Description

  The present invention relates to a functional sheet such as a cleaning sheet for cleaning a flooring or the like mounted on the cleaning unit of a cleaning tool including a cleaning unit and a rod-like handle connected to the cleaning unit, and a method for manufacturing the functional sheet. Is. In some cases, it is used as a functional sheet for floor protection such as floor protection, polishing, and waxing of flooring materials used for care. In addition, the functional sheet is not limited to a cleaning sheet, and can also be used as a wet tissue, hand wipe, body wipe, makeup remover, and the like.

As a conventional mop-shaped cleaning tool, for example, cleaning to remove foreign matter such as dust on the floor, hair, solid waste, seasoning, stain stains, adhering liquid, floor protection, floor care such as polishing Such a cleaning sheet is known as a functional sheet.
For example, as described in Patent Document 1, a type of cleaning sheet that is impregnated with a cleaning agent and directly wiped by hand is known. However, when this is mounted on a mop-shaped cleaning tool for cleaning, it is difficult to achieve both stains on the floor, cleanability, and operability of lightly wiping with one hand.
Patent Document 2 describes a cleaning sheet that is impregnated with a cleaning agent and wiped by hand. When this cleaning sheet is attached to a mop-shaped cleaning tool, the fiber may be caught by a protrusion on the floor and the sheet may be torn. Moreover, when it is used by being mounted on a mop-shaped cleaning tool, the cleaning agent is excessively discharged at the beginning of wiping, and there is no sustainability even if it is desired to clean a large area.
Accordingly, as described in Patent Document 3, Patent Document 4, and Patent Document 5, a disposable cleaning sheet is generally cleaned by supplying a cleaning agent or water to the cleaning sheet or the floor.

  In addition to the cleaning tool equipped with the cleaning sheet, such a cleaning method is very time-consuming, such as holding a cleaning agent in the hand, and removing the sheet from the cleaning tool in the middle of cleaning to wet it with water. In addition, when the amount of squeezing after wetting with water is weak, water may be excessively applied to the floor at the initial stage of cleaning, and the dirt may be spread on the contrary. Moreover, when the strength of the handle is weak like a mop for dry cleaning, the operability may be deteriorated. Furthermore, cracks such as cracks may be given to some wooden floors. In addition, although the above publication uses a cleaning sheet having a spunlace nonwoven fabric on the surface, the cleaning sheet is not sufficiently entangled with foreign matter such as hair and cotton dust in a water-containing state.

Japanese Utility Model Publication No. 4-89251 Japanese National Patent Publication No. 11-508256 Japanese Patent Laid-Open No. 10-262883 JP-A-10-286206 JP-A-9-131288 JP-T-2005-507271 JP 2005-42290 Gazette Japanese Patent Application No. 2006-214974

In particular, although Patent Document 1 discloses a cleaning sheet, there is no technical idea of storing a substance in a base material in a lattice pattern formed on the surface. Further, Patent Document 2 discloses a technique in which hair or the like protrudes from the surface of the support as a result of the rubbing operation. There is no technical idea of storing.
Patent Document 3 discloses a configuration that has good slipperiness, excellent water absorption and water retention, and can be used for both dry wiping and water wiping. Since the three-layer sheet is pressed and depressed at the joining line, a swell is formed on the sheet at the boundary between the joining line and the non-joining line. Although there is a statement that the effect is exhibited (paragraph [0034]), there is no idea of storing a substance in the cleaning sheet.
Furthermore, the embossed cleaning sheet of Patent Document 4 has a plurality of convex portions, and each convex portion is divided by a linear concave portion. In this embodiment, a continuous rhombus-like pattern is formed by the recess, and therefore there is no concept of storing a substance in the cleaning sheet.

  Patent Document 5 includes a wiping portion made of a liquid-permeable cleaning sheet and a liquid absorber that absorbs the liquid wiped by the wiping portion, and the cleaning sheet has a number of convex portions. In this technique, the area of the convex portion that contacts the surface to be cleaned at the time of cleaning is 5 to 60% with respect to the area of the entire cleaning sheet. However, as a result of experiments conducted by the inventors, the area of the convex portion that contacts the surface to be cleaned during cleaning is more than 5 to 60% of the total area of the cleaning sheet. Cleaning sheet used for removing stains, stains, adhering liquids, protecting floors, polishing, etc. works on dust, hair, solid debris, smudges, adhering liquids etc. and subsequent flow. Turned out to be affected.

  Furthermore, in Patent Document 6, a wiping substrate used in combination with substances such as ingredients and blending is disposed on the surface of a synthetic resin sheet found in the home or workplace, and the substance is applied to the substrate. The concept of storing is used. The shear force-sensitive micropockets described in Patent Document 6 are fine-scale three-dimensional sections in the surface of the substrate, and along the surface of the substrate when the substrate is in contact with the target surface. When a shearing force is applied, the shearing force substantially deforms the wall surface of the micropocket and releases the substance to the target surface. However, even when the base material has a plurality of micro pockets, when the cleaning part of the cleaning tool is reciprocated from the front to the back as shown in the example of FIGS. 19 to 27 published in Patent Document 6, When reciprocating left and right, moving in a specific direction guides dust on the floor, hair, solid debris, stains, adhering liquid, etc., and moves directly from one side of the cleaning part of the cleaning tool to the other opposite side. Therefore, the foreign matter securing efficiency does not increase.

In addition, in patent document 7, a pulp fiber layer is located between two card web layers, this is mounted on the support body of a coarse plain weave structure, a high pressure water stream is injected, and fibers are intertwined. In addition, a kitchen towel is disclosed in which a plurality of low integration regions and a plurality of high integration regions having a thickness larger than the thickness of the low integration region are formed to obtain a kitchen towel.
However, although it is distinguished from the low integration area and the high integration area, the maximum and minimum peak values of the low integration area and the high integration area, and the boundary between them are not clearly separated. It is not specified and is unknown. In particular, the highest peak value and the lowest peak value are connected to the top and bottom of FIG. 1 published in Patent Document 7, but on the foreign matter such as dust on the floor, hair, solid dust, stain stains, adhering liquid, etc. Even if a kitchen towel is placed on the wall, it cannot be secured as a foreign object.

Therefore, the inventors previously filed a patent application for the invention of Patent Document 8.
The functional sheet of the present invention draws a virtual reference line perpendicular to the opposing long sides of a rectangular reference sheet made of a nonwoven fabric sheet or a woven fabric sheet, and the reference sheet is drawn with respect to the drawn virtual reference line Lines formed so that the inclination angles of −45 degrees and +45 degrees do not intersect with each other due to the collection of non-woven fibers on the surface, and the line widths of −45 degrees and the lines of +45 degrees have the same line thickness and the same. A plurality of independent filament groups formed with the filament length, the same filament interval, and the same number of filaments are formed.
Moreover, the virtual straight line connecting the lowest ends of the filaments in the adjacent independent filament group is at the overlapping position where the virtual straight lines connecting the highest ends of the filaments at the shortest distance from the adjacent independent filament group overlap. Since the foreign matter that moves between the filaments collides with the filaments of the independent filament group, and the reflected foreign substances collide with the filaments in the independent filament group one after another, the cleaning unit In addition to eliminating the cleaning leakage of passing straightly without colliding with the lower surface of the cleaning unit main body surface, dust on the floor, hair, solid dust, stain stains, A foreign substance such as an adhering liquid can be submerged and held repeatedly, or floor management such as floor protection and polishing can be performed.

Therefore, the inventors have repeated various experiments, and as a result, it has been confirmed that removal of foreign matters such as dust on the floor, hair, solid dust, stain stains, adhering liquid, etc., and securing of efficient foreign matters are performed. Found the reason why is not retained.
In other words, a non-woven sheet or a rectangular reference sheet made of a woven cloth sheet is partially expanded and contracted due to floor irregularities, undulations, foreign matter adhesion, etc., and dust, hair, solid dust, stains on the retained floor It has also been found that even if foreign matters such as dirt and adhering liquid are removed, they are released in the middle, and it is not possible to maintain the foreign matter, or the amount is scattered although it is a small amount.
In particular, since the deformation of the reference sheet is used by pressing the reference sheet against the floor surface, the deformation of the reference sheet is a big problem.

  Accordingly, the present invention eliminates such conventional problems, removes foreign matter such as dust on the floor, hair, solid waste, seasonings, stains, and adhering liquid and holds it to protect the floor and polish the floor. It is an object of the present invention to provide a functional sheet that can be used as a cleaning sheet and wet tissue, a wipe, a body wipe, a makeup remover, etc. that is used for management and that efficiently retains and secures foreign substances. is there.

The functional sheet according to the invention of claim 1 is composed of a reference sheet formed by laminating non-woven fabrics, and a vertical beam and a horizontal beam formed of a synthetic resin strip, and both the vertical beam and the horizontal beam are joined. A mesh sheet in which a space is formed by the vertical beam and the horizontal beam, and the mesh sheet surface is disposed on the reference sheet, and the vertical sheet and the horizontal beam of the reference sheet and the mesh sheet are connected with water flow. It is integrated by the combined treatment.
Here, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyethylene fiber, polypropylene fiber, polyolefin fiber, aramid fiber, rayon fiber, glass fiber, etc. can be used as a reference sheet formed by laminating nonwoven fabrics. Basically, a synthetic resin, which is a raw material, is melted to make a thread, and the fiber is spread on the net of the standard sheet as it is. Have gained.
In addition, as a material for the mesh sheet, polyamide, polypropylene, polyethylene, acrylonitrile butadiene styrene, polycarbonate, polystyrene, vinyl chloride, phenol resin, or the like can be used. Of course, the material of the mesh sheet is preferably the same material as that of the reference sheet, and the mesh sheet material may be mixed with glass fiber, aramid fiber, carbon fiber or the like for preventing extension.

Then, the vertical beam and the horizontal beam of the net-like sheet are melted and joined at the initial stage when extruded as the same material, for example, polypropylene, so that the vertical beam and the horizontal beam are integrated. For joining the reference sheet and the net-like sheet, basically, the reference sheet is joined by a spunlace method (water flow entanglement method) in which non-woven fibers are entangled with a high-pressure water stream.
Furthermore, the space formed by the vertical rail and the horizontal rail of the mesh sheet forms a structure that is difficult to stretch, and a triangular or quadrangular space is desirable. In particular, it has been confirmed by the inventors that, as long as each side of a rectangular space is 15 mm or less, even if a single space independently extends due to the hooking of the reference sheet, there is little deformation as a whole. Further, since the vertical beam and the horizontal beam can be pushed out from the nozzle as a single thread, a triangular or quadrangular space is inexpensive to produce.
Furthermore, since the reference sheet and the mesh sheet are arranged, and the vertical beam and the horizontal beam are integrated by a hydroentanglement process, the nonwoven fabric fibers are wound around the vertical beam and the horizontal beam, Since it is not a partial connection but a two-dimensional or three-dimensional connection, the integration is firm.
Here, what is expressed as the vertical beam and the horizontal beam is a striate body. In the embodiment, the thickness of the line of the vertical beam and the horizontal beam is about 0.05 to 0.1 mm. Yes, at the intersection, it is about 0.2 to 0.5 mm.

The space of the mesh sheet of the functional sheet according to the invention of claim 2 is such that one space is a triangle or a quadrangle.
Here, the vertical beam and the horizontal beam are extruded from the nozzle as a single thread, and a triangular or quadrangular space can be formed by simple nozzle control, so that an inexpensive manufacturing apparatus can be obtained.
Although one space is a triangle or a quadrangle, in the case of carrying out the present invention, any shape that does not expand and contract may be used.

The hydroentanglement process by the spunlace method of the mesh sheet with respect to the reference sheet of the functional sheet according to the invention of claim 3 is performed so that fiber materials gather around the mesh sheet.
Here, in the spunlace method, the nonwoven fabric fibers are sprayed with a water flow, and the reference sheet and the mesh sheet are firmly integrated with the nonwoven fabric fibers intertwined by the sprayed nonwoven fabric fibers.

The method for producing a functional sheet according to the invention of claim 4 comprises a reference sheet processing part of a reference sheet in which nonwoven fabrics are laminated by a spunbond method, and a vertical beam and a horizontal beam formed by a solid linear body of a synthetic resin, By joining both the vertical beam and the horizontal beam, a mesh sheet processing unit for a mesh sheet having a space at the vertical beam and the horizontal beam, and the mesh sheet surface is disposed on the reference sheet surface, The crosspiece and the horizontal crosspiece are integrated with each other by a water entanglement process.
Here, as the reference sheet formed by laminating the nonwoven fabric of the reference sheet generation processing section by the spunbond method, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyethylene fiber, polypropylene fiber, polyolefin fiber, aramid fiber, rayon Fiber, glass fiber, etc. are used.
Moreover, polyamide, polypropylene, polyethylene, acrylonitrile butadiene styrene, polycarbonate, polystyrene, vinyl chloride, phenol resin, or the like is used as the material of the mesh sheet used in the mesh sheet generation processing unit. Of course, the same material as that of the reference sheet is preferable for the material of the mesh sheet, but glass fiber, aramid fiber, carbon fiber or the like for preventing extension may be mixed into the material of the mesh sheet.

Then, the joining of the vertical beam and the horizontal beam of the mesh sheet generation processing unit is performed by using the same material for the reference sheet used in the mesh sheet generation processing unit and the mesh sheet used in the mesh sheet generation processing unit, and fusing them together. Is desirable. When an adhesive is used, hot melt is suitable, and general low density polyethylene resin and ethylene vinyl acetate resin can be used. Moreover, it is good also as use of copolyamide resin and copolyester resin. Of course, the vertical beam and the horizontal beam may be made of polypropylene, for example, and both may be joined at the initial stage when the molten synthetic resin is extruded.
Furthermore, the space formed by the vertical beam and the horizontal beam of the mesh sheet of the mesh sheet generation processing unit forms a structure that does not easily stretch, and a triangular or quadrangular space is desirable. In particular, the inventors have confirmed that, as long as each side of a rectangular space is 15 mm or less, even if a single space extends independently due to catching, the deformation as a whole is small. Further, since the vertical beam and the horizontal beam can be pushed out from the nozzle as a single thread, a triangular or quadrangular space is inexpensive to produce.
Furthermore, since the reference sheet and the mesh sheet are arranged and the vertical beam and the horizontal beam are integrated by a water entanglement process, the integration of the non-woven fabric is performed by the water entanglement process. It winds around the crosspiece and the horizontal crosspiece, is integrated, and becomes firm.

The functional sheet of the invention of claim 1 is composed of a reference sheet formed of a nonwoven fabric laminated by a spunbond method, and a vertical beam and a horizontal beam formed of a linear body of synthetic resin, both of the vertical beam and the horizontal beam. And a mesh sheet that forms a space surrounded by the vertical beam and the horizontal beam, and the vertical beam and the horizontal beam of the mesh sheet are connected to the reference sheet by hydroentanglement processing. To be integrated.
Therefore, even if the reference sheet made of non-woven fabric is caught due to floor irregularities, undulations, foreign matter adhesion, etc., and partly expands and contracts, dust, hair, solid dust, stains, adhesion on the retained floor When holding foreign objects such as liquid, the mesh sheet protects the reference sheet from being stretched or torn by catching on the floor protrusions or deposits, etc. Dust on the floor, hair, Since foreign matters such as solid dust, stain stains, and attached liquid are not released, it is possible to maintain the foreign matters and prevent them from being scattered. The mesh sheet attached to the reference sheet can suppress expansion and contraction even when the reference sheet is pressed against the floor surface, allowing foreign matter such as dust on the floor, hair, solid debris, stain stains, and adhering liquid to enter. Can be held. In the elastic change of the mesh sheet attached to the reference sheet, the foreign matter once held by the reference sheet is not easily released.

In particular, the space surrounded by the vertical rail and the horizontal rail does not capture foreign matter such as hair, solid waste, stain stain, adhering liquid directly in the space, and by prohibiting the expansion of the space, Since the state of the nonwoven fabric wound around the vertical rail and the horizontal rail of the reference sheet is maintained, even fine dust is not scattered.
Further, if the temperature at the time of joining the reticulated sheet and the reference sheet is set to the temperature in the molten state, both can be joined, so that it is not necessary to use a special binder (adhesive), so that the binder processing can be omitted.
In addition, since the space surrounded by the vertical beam and the horizontal beam becomes a three-dimensional space at the intersection of the vertical beam and the horizontal beam, the mesh sheet becomes a three-dimensional space and further suppresses expansion and contraction of the mesh sheet. can do. Furthermore, since one side of the mesh of the mesh sheet is 15 mm or less, for example, even in uniform floor cleaning, force can be uniformly applied to the entire floor surface, and cleaning without waste can be performed.
Furthermore, when the functional sheet of the present invention is used as a cleaning sheet or the like, it can be cut in consideration of the mesh, and it can be confirmed whether there is no mistake in the interval at which it is cutting.
In addition, the vertical beam and the horizontal beam are striated bodies, and the thickness of the line of the vertical beam and the horizontal beam is about 0.05 to 0.1 mm, and the intersection is about 0.2 to 0.5 mm. Since the absolute area is small, the mesh sheet does not interfere with the function of the reference sheet. In addition, since the volume of the mesh sheet is small, the capacity of the mesh sheet is small, and the reference sheet is not deformed even when melt-bonding.

  Since the space formed by the mesh sheet of the functional sheet of the invention of claim 2 is a space surrounded by the vertical beam and the horizontal beam, the space is a triangle or a quadrangle. In addition to the effect, if the space is a triangle, the extension of each side is reduced. Further, when the space is a square, particularly when one side is 15 mm or less, the extension of each side becomes a three-dimensional distortion, and the deformation of the space can be suppressed.

  Since the hydroentanglement process of the mesh sheet with respect to the reference sheet of the functional sheet of the invention of claim 3 is performed so that fiber materials are gathered around the mesh sheet, claim 1 or claim 2 In addition to the effects described in (1), the vertical beam and the horizontal beam of the mesh sheet can be firmly integrated with the reference sheet by a water entanglement process.

The method for producing a functional sheet according to the invention of claim 4 is the intersection of a reference sheet generation processing unit for obtaining a reference sheet formed of a nonwoven fabric by a spunbond method and a vertical beam and a horizontal beam formed of a synthetic resin strip. By joining the vertical rail and the horizontal rail to obtain a mesh sheet in the space surrounded by the vertical rail and the surface of the reference sheet and the surface of the mesh sheet, the spunlace method And an integration process for integrating the vertical beam and the horizontal beam of the mesh sheet with the reference sheet by a water entanglement process.
Therefore, in the reference sheet generation processing section, a reference sheet is formed with a nonwoven fabric by the spunbond method, etc., and this reference sheet is partially expanded and contracted due to floor irregularities, undulations, foreign matter adhesion, etc. Make it possible to remove and capture foreign objects such as dust, hair, solid debris, stains and adhering liquid on the floor. The mesh sheet generation processing unit obtains a mesh sheet in a space surrounded by the vertical beam and the horizontal beam by joining the intersections of both the vertical beam and the horizontal beam. The mesh sheet obtained by the spunlace method formed by the mesh sheet generation processing unit protects the reference sheet from being stretched or torn by catching on the floor protrusions, deposits, etc. Since foreign matter such as dust, hair, solid dust, stain stains and adhering liquid is not released, it is possible to maintain the foreign matter and prevent the foreign matter from being scattered. The mesh sheet attached to the reference sheet can suppress expansion and contraction even when the reference sheet is pressed against the floor surface, allowing foreign matter such as dust on the floor, hair, solid debris, stain stains, and adhering liquid to enter. Can be held.

In particular, the space surrounded by the vertical rail and the horizontal rail does not capture foreign matter such as hair, solid waste, stain stain, adhering liquid directly in the space, by prohibiting the expansion of the space, Since the spunlace method maintains the state of the nonwoven fabric wound around the vertical beam and the horizontal beam of the reference sheet, even fine dust is not scattered.
Further, if the temperature at the time of joining the reticulated sheet and the reference sheet is set to the temperature in the molten state, both can be joined, so that it is not necessary to use a special binder (adhesive), so that the binder bonding process can be omitted.
In addition, since the space surrounded by the vertical beam and the horizontal beam becomes a three-dimensional space at the intersection of the vertical beam and the horizontal beam, the mesh sheet formed by the spunlace method becomes a three-dimensional space, and the mesh sheet Can be further suppressed. Furthermore, since one side of the mesh of the mesh sheet is 15 mm or less, for example, even in uniform floor cleaning, a force sheet can be applied to the entire floor surface, and a functional sheet that can be cleaned without waste is obtained.
Further, the vertical beam and the horizontal beam are striated bodies, and the thickness of the line of the vertical beam and the horizontal beam is about 0.05 to 0.1 mm, and the intersection is about 0.2 to 0.5 mm. In addition, since the absolute area is small, the mesh sheet does not disturb the function of the reference sheet. In addition, since the volume of the mesh sheet is small, the capacity of the mesh sheet is small, and the reference sheet is not deformed even when melt-bonding.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that, in the embodiments, the same reference numerals and the same reference numerals are the same or corresponding functional parts, and therefore, redundant description thereof is omitted here.

[Embodiment 1]
First, the case where the functional sheet 6 according to the embodiment of the present invention is used as the cleaning sheet 1 will be described with reference to the drawings.
As shown in FIG. 1, a conventional cleaning tool 10 includes a rectangular cleaning part 11 parallel to the floor surface, a biaxial connecting part 12 rotatably connected to the cleaning part 11, and two axes thereof. It has a rod-like handle 13 that is connected to the connecting portion 12 and can be tilted up and down, and further, the cleaning portion 10 has six corners that interpolate at four corners of the cleaning sheet 1 or its long side. Has a sheet holding portion 14 composed of four or six locking holes for locking and holding the cleaning portion 11 connected to the rotating biaxial connecting portion 12 and connected to the biaxial connecting portion 12 The surface of the cleaning unit 11 on the opposite side is a cleaning unit main body surface 15.

The cleaning sheet 1 as the functional sheet 6 is mounted so as to cover the cleaning unit main body surface 15 on the lower surface of the cleaning unit 11 and to be engaged with the sheet holding units 14 at the four corners on the left and right sides. Therefore, after wetting with water and squeezing excess water, it can be used as it is for cleaning. That is, the cleaning sheet 1 can clean the floor surface and the like in the same manner as a normal mop.
In this type of cleaning sheet 1 according to the present embodiment, since a reference sheet 2 described later is formed from pulp fibers and thermoplastic fibers, the friction resistance value at the time of cleaning is low, and water is wiped smoothly with a light force. be able to.

Further, as shown in FIGS. 1 to 7, the rectangular cleaning sheet 1 includes a reference sheet 2 formed of nonwoven fabric laminated by a spunbond method, and a vertical beam formed by extruding a synthetic resin solid with a filament. _{A 1, A 2, ··· A} n and rungs B _1, B _2, consists · · · B _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, ... intersection of both C ₁ to B _n, C _2, and joining the ...

In addition, when implementing this invention, the reference | standard sheet | seat 2 formed with the nonwoven fabric which consists of a laminated long nonwoven fabric fiber or a short nonwoven fabric fiber is not limited to the spunbond method, The one formed by the spunlace method But you can. This invention does not ask the manufacturing method.

  In the reference sheet 2 formed by laminating by the spunbond method, the non-woven fabric is a fabric bonded by a chemical or physical method without weaving chemical fibers, glass fibers, metal fibers, natural fibers or the like. The nonwoven fabric used in the present invention has a short production period and is low in cost. Specifically, as the nonwoven fabric used for the reference sheet 2, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyethylene fiber, polypropylene fiber, polyolefin fiber, aramid fiber, rayon fiber, glass fiber and the like can be used.

  The reference sheet 2 formed by laminating non-woven fabrics by the spunbond method removes and retains foreign matters such as dust, hair, solid waste, seasonings, stains, and adhering liquid on the floor, and protects and polishes the floor. Also in the floor management, the agent such as wax is held and the supply of the agent such as wax is made uniform. In particular, the reference sheet 2 can also be used as a cleaning sheet 1 and wet tissue that efficiently holds and secures foreign matters, wipes, body wipes, makeup removers, and the like. In addition, although this reference | standard sheet | seat 2 is normally formed with the long fiber and short fiber of a nonwoven fabric, use of only a short fiber is not denied. In particular, strength and suppleness, it is difficult to break even when wet, low cost, suitable for mass production, the reference sheet 2 is made of a single material, using a nonwoven fabric of long fibers, etc. In carrying out the present invention, short fibers can be used.

  Moreover, as a material of the mesh sheet 3, polyamide, polypropylene, polyethylene, acrylonitrile butadiene styrene, polycarbonate, polystyrene, vinyl chloride, phenol resin, or the like is used. Of course, the reticulated sheet 3 is preferably made of the same material as that of the reference sheet 2, but may be made of a completely different material. In this case, it is also possible to use a mixture of glass fiber, aramid fiber, carbon fiber, or the like for preventing extension as the material of the mesh sheet 3.

Further, for example, when the molding temperature of the mesh sheet 3 is made higher than the molding temperature of the reference sheet 2 to integrate the both, the mesh sheet 3 and a part of the reference sheet 2 are fused. Adhesive and moderate joining is performed.
The vertical bar A _1, A ₂ of the net-like sheets 3, ··· A _n and rungs B _1, B _2, space of the rectangular shape shown in FIG. 2 formed in _{··· B n d 1, d 2} , ·· D _n forms a structure that does not easily stretch, and in particular, if a square space has a side of 15 mm or less, preferably 10 mm or less and 3 mm or more, a single space d ₁ , d ₂ ,・ ・ ・ D _n does not extend independently, and the inventors have confirmed that there is little deformation as a whole. Further, since the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n can be pushed out from the nozzle as a single thread, the rectangular spaces d ₁ , d _2, ··· d _n the production cost also becomes cheaper.

The vertical rails A ₁ , A ₂ ,... _An are linear rails (wires) extending in parallel with the conveyance direction of the functional sheet manufacturing apparatus described later, and the horizontal rails B ₁ , B ₂ ,. _Bn is a straight bar (wire) extending in a direction perpendicular to the conveying direction of the manufacturing apparatus described later. Vertical bar _{A 1, A 2, ··· A} n is the nozzle hole 62, 63 and 64 of a predetermined interval to form a nozzle hole 85, 86 and 87, the reference sheet 2 by free fall of the molten synthetic resin vertical bar a _1, a ₂ above, · · · a _n and rungs B _1, B _2, which is drawn · · · B _n. In addition, the horizontal rails B ₁ , B ₂ ,... B _n are based on a long line in the horizontal direction by opening and closing the gates of the straight holes arranged at right angles to the conveying direction of the manufacturing apparatus at a predetermined timing. It is drawn on the sheet 2. Of course, the vertical bar _{A 1, A 2, ··· A} n and rungs _{B 1, B 2, ··· B} n is a resin made of solid.

That is, a hot melt adhesive is suitable for bonding the reference sheet 2 and the net-like sheet 3, but general low density polyethylene resin and ethylene vinyl acetate resin can also be used. Moreover, it is good also as use of copolyamide resin and copolyester resin. However, when practicing the present invention, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, and · · · B _n, the same material, for example, a polypropylene was extruded Most preferably, the two are melted and bonded in the initial stage.

In any case, the reference sheet 2 and the net-like sheets 3, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, intersections of _{··· B n C 1, C 2} , · in · · C _n, or between the reference sheet 2 and the net-like sheets 3 are fused bonded to each other.
Incidentally, the vertical bar A _1, A ₂ of the present embodiment, · · · A _n and rungs B _1, B _2, intersections of _{··· B n C 1, C 2} , ··· C n , the reference The sheet 2 and the net-like sheet 3 are made of the same material, and their temperature is set to be equal to or higher than the melting point.

Vertical bar A _1, A ₂ of the net-like sheets 3, · · · A _n and rungs B _1, B _2, space d _1, d ₂ formed in ··· B _n, ··· d _n is the space d _1, d _2, hardly elongation · · · d _n, is intended to form a hardly deformed structure, in particular, the space of square _{d 1, d 2, ··· d} n is each side 15mm or less, 3 mm or more if the space d ₁ of a single by snagging nonwoven reference sheet 2, d _2, also extend · · · d _n are independently as a whole, it deformed less is confirmed by the inventors It was. Further, by controlling the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n as a single thread, the rectangular spaces d ₁ , d ₂ , ... d _n can be formed, and the production cost is also low. Here, the space of square d _1, d _2, and that the sides of · · · d _n is not less than 3mm, the cleaning function of the reference sheet 2 is a distance that can be maintained.
The thicknesses of the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n are about 0.05 to 0.1 mm. However, at the intersections of the intersection points C ₁ , C ₂ ,... C _n , it is about 0.2 to 0.5 mm.

Vertical bar _{A 1, A 2, ··· A} n and rungs _{B 1, B 2, ··· B} n is the striatum, the vertical bar _{A 1, A 2, ··· A} n , rung The thickness of the lines B ₁ , B ₂ ,... B _n is about 0.05 to 0.1 mm, and the intersection is about 0.2 to 0.5 mm. Does not interfere with the operation of the reference sheet 2. Further, since the volume of the mesh sheet 3 is small, the heat capacity held by the mesh sheet 3 is small, and the synthetic resin fibers of the reference sheet 2 are not deformed even when melt-bonding.
The above-described embodiments, the space of square d _1, d _2, has been described · · · d _n, the space d △ _1, d △ ₂ triangles shown in FIG. 3, for the · · · d △ _2n It can be formed similarly.
That is, the vertical bar _{A 1, A 2, ··· A} n is a straight line extending in the conveying direction of the manufacturing apparatus, the rungs B _1, B _2, with respect to the conveying direction of the · · · B _n manufacturing apparatus It is a straight line extending in a perpendicular direction. The inclination rungs _{E 1, E 2, ··· E} n is a straight line extending in the direction of 135 degrees with respect to the conveying direction of the manufacturing equipment (45 degrees).

Accordingly, the inclined lateral beam _{E 1, E 2, ··· E} n is set from the vertical bar A ₁ to repeatedly move the distance between the vertical bar A ₂ between the rungs B ₁ and rung B ₂ Thus, it is drawn on the drum to form triangular spaces dΔ ₁ , dΔ ₂ ,... DΔ _2n .

In particular, the space of square d _1, d _2, if · · · d _n than each side 15mm or less, a single space d _1, d ₂ by caught, even extend · · · d _n is independently As a whole, the inventors have confirmed that there is little deformation. In addition, since the vertical bars A ₁ , A ₂ ,... A _n and the horizontal bars B ₁ , B ₂ ,... B _n of the mesh sheet 3 can be extruded from the nozzle as a single thread, they are triangular or quadrangular. space d _1, d ₂ of, ··· d _n the production cost also becomes cheaper. However, when implementing this invention, it is not limited to the structure of these mesh sheets 3.

Reference sheet 2 formed by the spunbond method, the vertical bar A _1, A ₂ of the net-like sheets 3, · · · A _n and rungs _{B 1, B 2, ··· B} n, the intersection C _1, C ₂ , before the hydroentanglement process 5 · · · C _n, because the temperature is raised above the molding temperature, they are bonded.
However, it has been found that the reference sheet 2 and the net-like sheet 3 can be detached only by applying a large external force and are not joined to each other, so that they are weak against the external force.
Therefore, considering the expansion and contraction of the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n of the mesh sheet 3, the surfaces of the reference sheet 2 and the mesh sheet 3 are considered. And the effect of the water entanglement treatment 5 such as the spunlace method is required.

Specifically, as shown in FIGS. 5 and 7, a manufacturing method will be described for a functional sheet manufacturing apparatus that manufactures the cleaning sheet 1 of the present embodiment.
In the figure, a conveyor 21 including a conveying roller 20a, a conveying roller 20b, and the like sequentially forms the reference sheets 2 by a spunlace method while conveying from the left to the right in the drawing. That is, the first spunlace processing unit 30 for obtaining the reference sheet 2 formed of laminated nonwoven fabrics is formed. In the present embodiment, the spunlace method is used to obtain the reference sheet 2 without using the spunbond method.
The first spunlace processing unit 30 is provided with a spunlace nozzle (nonwoven fabric nozzle) 22 that entangles the aggregate of nonwoven fabric fibers with the reference sheet 2. Since the modification is easy, the cleaning sheet 1 is manufactured using a spunlace method in which fibers are entangled with a high-pressure water stream. In addition, a baffle plate (not shown) and an air nozzle 23 that rectify the air flow are disposed at the inlet of the first spunlace processing unit 30.

The collection tank 25 is a container that collects excess liquid containing excess fibers that have not been used in the reference sheet 2. The liquid containing fibers collected in the collection tank 25 is agitated and contains foreign substances such as dust. The mixture is removed and supplied to a stirring filter 26 that passes only the target fiber. The required amount of fiber and liquid are mixed and supplied by the stirring filter 26.
Fluid consisting of nonwoven fabric fibers and liquid is supplied by pumps 27A and 27B that are independently arranged to circulate the fluid. The pump 27A and the pump 27B that generate a predetermined pressure for supplying the fluid are passed through the pipe line 28 and the pipe line 29, and the first spunlace processing unit 30 or the second spunlace processing unit 40 is allowed to stir the non-woven fiber. Feed the fluid.

In the first spunlace processing section 30, a plurality of spunlace nozzles 31 are arranged at an angle in the length direction (traveling direction) of the conveyor 21. That is, the spunlace nozzle 31 is arranged perpendicular to the traveling direction of the conveyor 21.
That is, jet spray is ejected from the plurality of spunlace nozzles 31 as a row. Thereby, a specific surface of the reference sheet 2 is formed.

At this time, the manifold 32 is disposed in the pipe line 28 of the first spunlace processing unit 30, adjusts the pressure of the spunlace nozzle 31, and energy of the spunlace method in which fibers are entangled with a high-pressure water flow between the reference sheet 2. The fiber is entangled with the reference sheet 2 with a high-pressure water flow. Thereby, the position and cross-sectional shape of the reference sheet 2 are specified.
That is, the reference sheet 2 is provided with a hole made of a plurality of round holes on a plane, and in the example shown in FIG. Normally, the manifold 32 and the first spunlace processing unit 30 are integrated.

At this time, the drying roller 34 is disposed at the outlet of the first spunlace processing unit 30 in which the spunlace nozzle 31 is disposed, and is applied to the reference sheet 2 and the reference sheet 2 disposed on one surface of the reference sheet 2. The moisture contained is squeezed and dried, and the moisture on the upper surface of the reference sheet 2 and the reference sheet 2 is removed.
The conveyor 21 conveys the reference sheet 2 to the end thereof, while the outer surface of the large-diameter pulley 50 whose inside is depressurized is sucked and rotated along the large-diameter pulley 50, and the opposite surface is connected to the conveyor 51a. It is transferred to the conveyor 51 and transferred from the right to the left in the figure.

The reference sheet 2 formed by the first spun lace processing unit 30 placed on the conveyor 21 is inverted by a large-diameter pulley 50, and the vertical rails A ₁ , A ₂ ,. · a _n and rungs B _1, B _2, consists · · · B _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, both of · · · B _n intersection C _1, C _2, by joining · · · C _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, a space surrounded by the · · · B _n The processing of the mesh sheet processing unit 60 for obtaining the mesh sheet 3 having the shape is started.
A synthetic resin fiber of the manifold 61 is pushed out from the spunlace nozzles 62, 63, 64 by a sensor (not shown), and the synthetic resin is drawn on the upper surface of the reference sheet 2 continuously and at a predetermined interval.

The pressure regulator 45 is disposed in the pipe line 29 of the second spunlace processing unit 40, adjusts the pressure of the spunlace nozzle 44, and adjusts the energy of the spunlace method in which the fibers are entangled with the high-pressure water flow between the reference sheet 2 and the pressure regulator 45. Then, the degree of the process of intertwining the fibers with the reference sheet 2 with a high-pressure water flow is adjusted. Thus, the vertical bar A _1, A ₂ to the reference sheet 2, · · · A _n and rungs B _1, B _2, the position of the · · · B _n, the cross-sectional shape is specified.
The drying roller 46 is disposed at the exit of the second spunlace processing unit 40 where the spunlace nozzle 44 is disposed, and the reference sheet 2 and the vertical rails A ₁ , A ₂ ,. .. The water contained in A _n and the horizontal bars B ₁ , B ₂ ,... B _n is squeezed and dried. In addition, a baffle plate (not shown) and an air nozzle 42 that rectify the air flow are provided.

As a result, the reference sheet 2 is U-turned by the large-diameter pulley 50, and the vertical beams A ₁ , A ₂ ,... _An and the horizontal beams B ₁ , B ₂ ,. ... entering the formation of B _n. Basically, since the surface of the reference sheet 2 is reversed by the large-diameter pulley 50, the vertical beams A ₁ , A ₂ ,... _An and the horizontal beams B ₁ , B ₂ ,. · B _n the intertwining earlier, the formation of the opposite surface.
The pressure regulator 45 is disposed in the pipe line 29 of the manifold 61, adjusts the pressure of the spunlace nozzle 44, and uses the energy of the spunlace method in which fibers are entangled with the high-pressure water flow between the reference sheet 2 and the first span of the conveyor 21. The lace processing unit 30 and the second span lace processing unit 40 of the conveyor 41 are adjusted independently.

Therefore, when the reference sheet 2 is introduced from the outside into the first spunlace processing unit 30, jet spray is ejected from the spunlace nozzle 22, and the first spunlace processing unit 30 between the conveyors 21 forms the reference sheet 2. It becomes the process which a fiber is entangled with the reference | standard sheet | seat 2 by the high-pressure water flow between nonwoven fabric fibers. That is, jet spray is sprayed from the spunlace nozzle 44, and the reference sheet 2 is entangled with the reference sheet 2 by the high-pressure water flow between the reference sheet 2 and the nonwoven fabric fibers in the second spunlace processing unit 40 between the conveyors 41. 2 is a process in which the mesh sheet 3 is entangled. Second spunlace processing section 40, the vertical bar A _1, A ₂ formed by a solid-like striatal synthetic resin, · · · A _n and rungs B _1, B _2, consists · · · B _n , vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , by joining · · · C _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, space surrounded by _{··· B n d 1, d 2} , ··· d n, d △ 1, d △ 2 ,..., DΔ _2n is obtained.

The functional sheet manufacturing method of the present embodiment is formed by a net-like sheet generation processing unit 60 that obtains the reference sheet 2 formed of the nonwoven fabric laminated by the first spunlace processing unit 30 and a solid filament of synthetic resin. vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, consists · · · B _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , by joining · · · C _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, ... A mesh sheet generation processing unit 60 for obtaining a mesh sheet 3 in which a space surrounded by B _n is obtained; _1, a _2, ··· a _n and rungs B _1, B _2, those comprising the integrated process for integrating · · · B _n in the standard sheet 2 and spunlace That. Here, the integrated processing means that the vertical beams A1, A2,... An and the horizontal beams B1, B2,. The Bn is integrated with the reference sheet 2 and corresponds to the water entanglement processing 5 and the span lace processing unit 97 by the second span lace processing unit 40 after the mesh sheet generation processing unit 60.

Here, as the reference sheet generation processing unit 60, the reference sheet 2 is formed of a non-woven fabric laminated by the spunlace method in the first spunlace processing unit 30, but when implementing the present invention, the spunlace method is used. However, the reference sheet generation processing unit 60 that forms the reference sheet 2 by the spunbond method can be configured.
That is, when the reference sheet 2 is formed, it means that the spunlace method, the spunbond method, or another method may be used.

Furthermore, the manufacturing method is demonstrated about the other example of the functional sheet manufacturing apparatus shown in FIG.6 and FIG.7 of the cleaning sheet 1 of this Embodiment formed in this way.
A reference sheet 2 formed by a spunbond method is supplied from the outside of the drawing apparatus. The reference sheet 2 may have a plate shape or a pattern, but a web shape as a network network of a nonwoven fabric is usually formed.

A net forming pulley 83 formed of a stainless steel plate of the cleaning sheet 1 as the functional sheet 6 of the present embodiment includes vertical bars A ₁ , A ₂ ,... _An and horizontal bars B ₁ , B ₂ ,. A manifold 84 and nozzles 85, 86, 87 forming B _n are disposed at the highest portion, and the vertical beam A ₁ , A ₂ ,... _An and the horizontal beam B ₁ , B are formed on the surface of the mesh forming pulley 83. ₂ ... B _n is drawn. Vertical bar A _1, A ₂ drawn, · · · A _n and rungs _{B 1, B 2, ··· B} n, the intersection C _1, C _2, figure · · · C _n is the net forming the pulley 83 It is formed in an annular shape, and is moved from the periphery of the net forming pulley 83 to the upper surface of the reference sheet 2 at the lowermost part of the net forming pulley 83.
By the tension rollers 88a and 88b, the reference sheet 2 and the net-like sheet 3 to which a predetermined tension is applied are overlapped. That is, the vertical bars A _1, A ₂ on the upper surface of the web forming the pulley 83, · · · A _n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , ··· C by joining _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, space surrounded by the · · · B _n intersections C _1, C _2, ··· C Processing of the mesh sheet generation processing units 60 and 80 for obtaining the mesh sheet 3 on which _n is formed is performed. Reticulated sheet generation processing unit 60 and 80, the vertical bar A _1, A ₂ formed by the solid of the striatum of the synthetic resin, · · · A _n and rungs B _1, B _2, consists · · · B _n , vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , by joining · · · C _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, space surrounded by _{··· B n d 1, d 2} , ··· d n, d △ 1, d △ 2 ,..., DΔ _2n is obtained.

Around the mask drum 90, the homogeneous reference sheet 2 is conveyed from the left to the right as shown in FIG. 6 by the tension roller 88a and the tension roller 88b so as to rotate along the outer periphery. Around the mask drum 90, the reference sheet 2 and the reticulated sheet 3 are rotated at the same speed as the outer periphery of the mask drum 90 in an angle range of 200 to 270 degrees.
The mask drum 90 formed of the stainless steel plate of the cleaning sheet 1 according to the present embodiment includes the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,. _n , intersections C ₁ , C ₂ ,... C _n are formed as through holes formed in an annular shape, and constitute a spunlace processing portion 97.

That is, the end of the mask drum 90 is closed, and a manifold 92 connected to the conduit 91 is disposed there. The pressure in the pipe 91 and the manifold 92 (not shown) is adjusted by adjusting the pressure of the spunlace nozzle 73 by a pressure regulator (not shown) and adjusting the energy of the spunlace method in which fibers are entangled with the high-pressure water flow between the reference sheet 2 and the pipe 91. The fiber is entangled with the reference sheet 2 with a high-pressure water flow. Thus, the vertical bar A _1, A ₂ to the reference sheet 2, · · · A _n and rungs B _1, B _2, the position of the · · · B _n, the cross-sectional shape is specified.
Below the mask drum 90, a collection tank 94 for collecting excess liquid after the nonwoven fabric fibers are entangled with the reference sheet 2 by high-pressure water flow is disposed. A stirring filter 95 is connected to the collection tank 94, and a necessary amount of nonwoven fabric fibers and liquid are mixed, and a fluid comprising the short fibers and liquid is supplied by a pump 96 that circulates the fluid.

A pump 96 that generates a predetermined pressure passes through the conduit 91 and supplies the manifold 92 with the required amount of nonwoven fibers and liquid. From this spunlaced nozzle 93 is always injected jet spray, vertical bars A _1, A ₂ by the short fibers within a predetermined angle range passes through the through holes of the mask drum 90, · · · A _n and rungs B ₁ , B ₂ ,... B _n are intertwined by the spunlace treatment section hydroentanglement process 5. At this time, the injection from the jet spray, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, the position of the · · · B _n becomes denser, also increased its mass It becomes a relatively highly elastic mass. As a result, the non-woven fabric near the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n has a dense fiber density and a large mass. Since the fiber density of the reference | standard sheet | seat 2 and the net-like sheet | seat 3 can be formed high, the absorption and holding | maintenance capability of a liquid become large by capillary action.

Therefore, the mask drum 90, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, because the through-hole to form a · · · B _n are formed, always span Jet spray is sprayed from the lace nozzle 63, and the spunlace processing unit 97 in the mask drum 90 causes the reference sheet 2 to be entangled with the reference sheet 2 by the high-pressure water flow of the nonwoven fabric fibers.
The figure shown in FIG. 2 is drawn as a through hole in the annular mask drum 90 so that the reference sheet 2 rotates at the same speed as the mask drum 90 along the periphery of the mask drum 90 around the mask drum 90. Furthermore, the tension roller 88a and the tension roller 88b move at a constant speed. That is, the shape of the reference sheet 2 is transferred to the reference sheet 2 around the mask drum 90 because the reference sheet 2 is at the same speed as the outer periphery of the mask drum 90 by the tension roller 88a and the tension roller 88b.

Therefore, since the jet spray is sprayed from the spunlace nozzle 63 through the through hole of the mask drum 90 and the fibers are entangled with the reference sheet 2 and the net-like sheet 3 by the high-pressure water flow between the nonwoven fabric fibers, the vertical beams A ₁ , A ₂ , · · a _n and rungs B _1, B _2, the density of only the position of · · · B _n increases, its mass also increases. At this time, the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n have a shape close to a lump, and the reference sheet is peeled off from the mask drum 90 in the meantime. On the floor side of 2, a low-density, low-mass foreign material passage is formed by the line spacing.
Also for the cleaning sheet 1 as the functional sheet 6 of this embodiment, the vertical beams A ₁ , A ₂ ,... _An and the horizontal beam B ₁ so that the nonwoven fabric fibers are intertwined with the reference sheet 2 by high-pressure water flow from one side. , B ₂ ,... B _n . In addition, the mesh sheet 3 in the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n has a high density of non-woven fibers and a large mass. Therefore, since the fiber density of the reference sheet 2 can be formed high, the ability to absorb and retain the liquid increases due to capillary action.

  The cleaning sheet 1 as the functional sheet 6 of the above embodiment further includes the long side of the reference sheet 2 on the long side of the cleaning unit main body surface 15 of the cleaning tool 10 and the short side of the cleaning unit main body surface 15 of the cleaning tool 10. Since the short side of the reference sheet 2 is attached in association with the side, the long side of the reference sheet 2 is attached to the cleaning unit main body surface 15 of the cleaning tool 10, and the cleaning unit main body surface 15 of the cleaning tool 10 is attached. You can definitely perform the installation on.

The functional sheet 6 of the above embodiment includes a reference sheet 2 formed of laminated nonwoven fabrics, vertical bars A ₁ , A ₂ ,... _An and horizontal bars B ₁ , formed of a synthetic resin solid filament. B _2, consists · · · B _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , ·· A space d ₁ , d ₂ ,... D _n , dΔ ₁ , d joined by C _n and surrounded by vertical bars A1, A2,... An and horizontal bars B1, B2,. △ _2, ··· d △ _2n features arranged a net-like sheet 3 formed with, vertical bar a _1, a ₂ of the net-like sheets 3 by hydroentanglement process 5, · · · a _n and rungs B _1, B ₂ ,... B _n are integrated with the reference sheet 2.

  Therefore, the reference sheet 2 formed of nonwoven fabric is partially expanded and contracted due to unevenness of the floor, undulations, adhesion of foreign matters, etc., and dust, hair, solid dust, stain stains, adhering liquid, etc. on the retained floor When the foreign material is removed and captured, the mesh sheet 3 protects the reference sheet 2 from being caught by protrusions and deposits on the floor and extending or torn, and the dust, hair, Since foreign matters such as solid dust, stains and adhering liquid are not released, it is possible to maintain the foreign matters and prevent them from being scattered. The net-like sheet 3 provided alongside the reference sheet 2 can suppress expansion and contraction even when the reference sheet 2 is pressed against the floor surface, and can remove foreign matter such as dust, hair, solid dust, stains, and adhering liquid on the floor. You can dive and hold.

In particular, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, space d _1, d ₂ surrounded by _{··· B n, ··· d n,} d △ 1, d △ _2, ··· d △ _2n, the space _{d 1, d 2, ··· d} n, d △ 1, d △ 2, directly hair, solid garbage ··· d △ _2n, stains dirt, not to capture foreign matters such as deposition liquid, the space _{d 1, d 2, ··· d} n, d △ 1, d △ 2, by inhibiting the growth of · · · d △ _2n, reference sheet 2 vertical bar a _1, a ₂ of, · · · a _n and rungs B _1, B _2, since it is intended to maintain the state of the nonwoven fabric wound around the · · · B _n, with reference sheet 2 fine after capture Even dust will not scatter them.
In addition, if the temperature at the time of joining the reticulated sheet 3 and the reference sheet 2 is set to a molten temperature, the two can be joined. Therefore, it is not necessary to use a special binder in the bonding process 4. Can be omitted.

The vertical bar A _1, A _2, · · · A _n and rungs B _1, B _2, intersections of ··· B _n C1, C2, the junction of · · · Cn is vertical bar A _1, A ₂ , · · · A _n and rungs B _1, B _2, space d _1, d ₂ surrounded by _{··· B n, ··· d n,} d △ 1, d △ 2, ··· d △ _{Since 2n} becomes a three-dimensional space, the mesh sheet 3 becomes a three-dimensional space, and expansion and contraction of the mesh sheet 3 can be further suppressed. Furthermore, since one side of the mesh of the mesh sheet 3 is 15 mm or less, for example, even in uniform floor cleaning, force can be applied to the entire floor surface, and cleaning without waste can be performed.

Space d _1, d ₂ formed in net-like sheets 3 functional sheet 6 of the above-described _{embodiment, ··· d n, d △ 1} , d △ 2, ··· d △ 2n is vertical bar A _1, A ₂ ,... A _n and one of the spaces surrounded by the horizontal bars B ₁ , B ₂ ,... B _n are triangular or quadrangular, the spaces dΔ ₁ , dΔ ₂ ,. .. When _dΔ2n is a triangle, the elongation of each side is reduced. A space d _1, d _2, the · · · d _n is a rectangle, in particular, when one side is 15mm or less may suppress the growth of each side.

Since the hydroentanglement process 5 of the mesh sheet 3 with respect to the reference sheet 2 of the functional sheet 6 of the above embodiment is performed so that the fiber material gathers around the mesh sheet 3, the hydroentanglement process 5 the vertical bar a _1, a ₂ of the net-like sheets, · · · a _n and rungs B _1, B _2, can be firmly integrated with · · · B _n and the reference sheet 2.

The functional sheet manufacturing method of the above embodiment includes a reference sheet generation processing unit for obtaining a reference sheet 2 formed of a nonwoven fabric by a spunbond method, and vertical bars A ₁ , A ₂ , ...

Therefore, in the reference sheet generation processing units 60 and 80, the reference sheet 2 is formed of a nonwoven fabric by a spunbond method or the like, and the reference sheet 2 is partially expanded or contracted due to floor irregularities, undulations, adhesion of foreign matters, and the like. It is possible to remove and capture foreign matter such as dust, hair, solid waste, stains, and adhering liquid on the held floor. Reticulated sheet generation processing unit 60, by joining the intersection of both vertical bars and rungs, vertical bar _{A 1, A 2, ··· A} n and rungs _{B 1, B 2, ··· B} n space d _1, d ₂ surrounded _{by, ··· d n, d △ 1} , d △ 2, to obtain the net-like sheets 3 ··· d △ _2n. The reticulated sheet 3 obtained by the spunlace method formed by the reticulated sheet generation processing unit 60 protects the reference sheet from being stretched or torn by being caught on floor protrusions or deposits, and retained during operation. Since foreign matter such as dust on the floor, hair, solid debris, stain stains, and attached liquid is not released, it is possible to maintain the foreign matter and prevent the foreign matter from being scattered. The net-like sheet 3 attached to the reference sheet 2 can suppress expansion and contraction even when the reference sheet is pressed against the floor surface, and foreign matter such as dust on the floor, hair, solid debris, stain stains, adhering liquid, etc. can be trapped in the floor. Can be held.

In particular, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, a space surrounded by the · · · B _n, the space _{d 1, d 2, ··· d} n, d △ _1, d △ _2, directly · · · d △ _2n hair, not to capture solid waste, stain dirt, foreign matters such as deposition liquid, the space _{d 1, d 2, ··· d} n, d △ _1, d △ _2, by inhibiting the growth ··· d △ _2n, vertical bar a _1, a ₂ of the reference sheet 2 by spun lace method, · · · a _n and rungs B _1, B ₂ Since the nonwoven fabric wound around _Bn is maintained, even fine dust is not scattered.
In addition, if the temperature at the time of joining the reticulated sheet 3 and the reference sheet 2 is set to a molten temperature, the two can be joined. There is no need to do.
The vertical bar A _1, A _2, · · · A _n and rungs B _1, B _2, the intersection point of intersection of _{··· B n C 1, C 2} , junction · · · C _n is the vertical bar A ₁ , A ₂ ,...

Since dΔ _2n becomes a three-dimensional space, the mesh sheet 3 formed by the spunlace method becomes a three-dimensional space, and the expansion and contraction of the mesh sheet can be further suppressed. Furthermore, since one side of the mesh of the mesh sheet 3 is 15 mm or less, for example, even in uniform floor cleaning, a force sheet can be applied to the entire floor surface, and a functional sheet 6 that can be cleaned without waste is obtained.

  The present invention relates to a functional sheet such as a cleaning sheet for cleaning a flooring or the like mounted on the cleaning unit of a cleaning tool including a cleaning unit and a rod-like handle connected to the cleaning unit, and a method for manufacturing the functional sheet. Is. In some cases, it is used as a functional sheet for floor protection such as floor protection, polishing, and waxing of flooring materials used for care. In addition, the functional sheet is not limited to a cleaning sheet, and can also be used as a wet tissue, hand wipe, body wipe, makeup remover, and the like.

As a conventional mop-shaped cleaning tool, for example, cleaning to remove foreign matter such as dust on the floor, hair, solid waste, seasoning, stain stains, adhering liquid, floor protection, floor care such as polishing Such a cleaning sheet is known as a functional sheet.
For example, as described in Patent Document 1, a type of cleaning sheet that is impregnated with a cleaning agent and directly wiped by hand is known. However, when this is mounted on a mop-shaped cleaning tool for cleaning, it is difficult to achieve both stains on the floor, cleanability, and operability of lightly wiping with one hand.
Patent Document 2 describes a cleaning sheet that is impregnated with a cleaning agent and wiped by hand. When this cleaning sheet is attached to a mop-shaped cleaning tool, the fiber may be caught by a protrusion on the floor and the sheet may be torn. Moreover, when it is used by being mounted on a mop-shaped cleaning tool, the cleaning agent is excessively discharged at the beginning of wiping, and there is no sustainability even if it is desired to clean a large area.
Accordingly, as described in Patent Document 3, Patent Document 4, and Patent Document 5, a disposable cleaning sheet is generally cleaned by supplying a cleaning agent or water to the cleaning sheet or the floor.

  In addition to the cleaning tool equipped with the cleaning sheet, such a cleaning method is very time-consuming, such as holding a cleaning agent in the hand, and removing the sheet from the cleaning tool in the middle of cleaning to wet it with water. In addition, when the amount of squeezing after wetting with water is weak, water may be excessively applied to the floor at the initial stage of cleaning, and the dirt may be spread on the contrary. Moreover, when the strength of the handle is weak like a mop for dry cleaning, the operability may be deteriorated. Furthermore, cracks such as cracks may be given to some wooden floors. In addition, although the above publication uses a cleaning sheet having a spunlace nonwoven fabric on the surface, the cleaning sheet is not sufficiently entangled with foreign matter such as hair and cotton dust in a water-containing state.

Japanese Utility Model Publication No. 4-89251 Japanese National Patent Publication No. 11-508256 Japanese Patent Laid-Open No. 10-262883 JP-A-10-286206 JP-A-9-131288 JP-T-2005-507271 JP 2005-42290 Gazette Japanese Patent Application No. 2006-214974

In particular, although Patent Document 1 discloses a cleaning sheet, there is no technical idea of storing a substance in a base material in a lattice pattern formed on the surface. Further, Patent Document 2 discloses a technique in which hair or the like protrudes from the surface of the support as a result of the rubbing operation. There is no technical idea of storing.
Patent Document 3 discloses a configuration that has good slipperiness, excellent water absorption and water retention, and can be used for both dry wiping and water wiping. Since the three-layer sheet is pressed and depressed at the joining line, a swell is formed on the sheet at the boundary between the joining line and the non-joining line. Although there is a statement that the effect is exhibited (paragraph [0034]), there is no idea of storing a substance in the cleaning sheet.
Furthermore, the embossed cleaning sheet of Patent Document 4 has a plurality of convex portions, and each convex portion is divided by a linear concave portion. In this embodiment, a continuous rhombus-like pattern is formed by the recess, and therefore there is no concept of storing a substance in the cleaning sheet.

  Patent Document 5 includes a wiping portion made of a liquid-permeable cleaning sheet and a liquid absorber that absorbs the liquid wiped by the wiping portion, and the cleaning sheet has a number of convex portions. In this technique, the area of the convex portion that contacts the surface to be cleaned at the time of cleaning is 5 to 60% with respect to the area of the entire cleaning sheet. However, as a result of experiments conducted by the inventors, the area of the convex portion that contacts the surface to be cleaned during cleaning is more than 5 to 60% of the total area of the cleaning sheet. Cleaning sheet used for removing stains, stains, adhering liquids, protecting floors, polishing, etc. works on dust, hair, solid debris, smudges, adhering liquids etc. and subsequent flow. Turned out to be affected.

  Furthermore, in Patent Document 6, a wiping substrate used in combination with substances such as ingredients and blending is disposed on the surface of a synthetic resin sheet found in the home or workplace, and the substance is applied to the substrate. The concept of storing is used. The shear force-sensitive micropockets described in Patent Document 6 are fine-scale three-dimensional sections in the surface of the substrate, and along the surface of the substrate when the substrate is in contact with the target surface. When a shearing force is applied, the shearing force substantially deforms the wall surface of the micropocket and releases the substance to the target surface. However, even when the base material has a plurality of micro pockets, when the cleaning part of the cleaning tool is reciprocated from the front to the back as shown in the example of FIGS. 19 to 27 published in Patent Document 6, When reciprocating left and right, moving in a specific direction guides dust on the floor, hair, solid debris, stains, adhering liquid, etc., and moves directly from one side of the cleaning part of the cleaning tool to the other opposite side. Therefore, the foreign matter securing efficiency does not increase.

In addition, in patent document 7, a pulp fiber layer is located between two card web layers, this is mounted on the support body of a coarse plain weave structure, a high pressure water stream is injected, and fibers are intertwined. In addition, a kitchen towel is disclosed in which a plurality of low integration regions and a plurality of high integration regions having a thickness larger than the thickness of the low integration region are formed to obtain a kitchen towel.
However, although it is distinguished from the low integration area and the high integration area, the maximum and minimum peak values of the low integration area and the high integration area, and the boundary between them are not clearly separated. It is not specified and is unknown. In particular, the highest peak value and the lowest peak value are connected to the top and bottom of FIG. 1 published in Patent Document 7, but on the foreign matter such as dust on the floor, hair, solid dust, stain stains, adhering liquid, etc. Even if a kitchen towel is placed on the wall, it cannot be secured as a foreign object.

Therefore, the inventors previously filed a patent application for the invention of Patent Document 8.
The functional sheet of the present invention draws a virtual reference line perpendicular to the opposing long sides of a rectangular reference sheet made of a nonwoven fabric sheet or a woven fabric sheet, and the reference sheet is drawn with respect to the drawn virtual reference line Lines formed so that the inclination angles of −45 degrees and +45 degrees do not intersect with each other due to the collection of non-woven fibers on the surface, and the line widths of −45 degrees and the lines of +45 degrees have the same line thickness and the same. A plurality of independent filament groups formed with the filament length, the same filament interval, and the same number of filaments are formed.
Moreover, the virtual straight line connecting the lowest ends of the filaments in the adjacent independent filament group is at the overlapping position where the virtual straight lines connecting the highest ends of the filaments at the shortest distance from the adjacent independent filament group overlap. Since the foreign matter that moves between the filaments collides with the filaments of the independent filament group, and the reflected foreign substances collide with the filaments in the independent filament group one after another, the cleaning unit In addition to eliminating the cleaning leakage of passing straightly without colliding with the lower surface of the cleaning unit main body surface, dust on the floor, hair, solid dust, stain stains, A foreign substance such as an adhering liquid can be submerged and held repeatedly, or floor management such as floor protection and polishing can be performed.

Therefore, the inventors have repeated various experiments, and as a result, it has been confirmed that removal of foreign matters such as dust on the floor, hair, solid dust, stain stains, adhering liquid, etc., and securing of efficient foreign matters are performed. Found the reason why is not retained.
In other words, a non-woven sheet or a rectangular reference sheet made of a woven cloth sheet is partially expanded and contracted due to floor irregularities, undulations, foreign matter adhesion, etc., and dust, hair, solid dust, stains on the retained floor It has also been found that even if foreign matters such as dirt and adhering liquid are removed, they are released in the middle, and it is not possible to maintain the foreign matter, or the amount is scattered although it is a small amount.
In particular, since the deformation of the reference sheet is used by pressing the reference sheet against the floor surface, the deformation of the reference sheet is a big problem.

  Accordingly, the present invention eliminates such conventional problems, removes foreign matter such as dust on the floor, hair, solid waste, seasonings, stains, and adhering liquid and holds it to protect the floor and polish the floor. It is an object of the present invention to provide a functional sheet that can be used as a cleaning sheet and wet tissue, a wipe, a body wipe, a makeup remover, etc. that is used for management and that efficiently retains and secures foreign substances. is there.

The functional sheet according to the invention of claim 1 is composed of a reference sheet formed by laminating non-woven fabrics, and a vertical beam and a horizontal beam formed of a synthetic resin strip, and both the vertical beam and the horizontal beam are joined. A mesh sheet in which a space is formed by the vertical beam and the horizontal beam, and the mesh sheet surface is disposed on the reference sheet, and the vertical sheet and the horizontal beam of the reference sheet and the mesh sheet are connected with water flow. It is integrated by the combined treatment.
Here, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyethylene fiber, polypropylene fiber, polyolefin fiber, aramid fiber, rayon fiber, glass fiber, etc. can be used as a reference sheet formed by laminating nonwoven fabrics. Basically, a synthetic resin, which is a raw material, is melted to make a thread, and the fiber is spread on the net of the standard sheet as it is. Have gained.
In addition, as a material for the mesh sheet, polyamide, polypropylene, polyethylene, acrylonitrile butadiene styrene, polycarbonate, polystyrene, vinyl chloride, phenol resin, or the like can be used. Of course, the material of the mesh sheet is preferably the same material as that of the reference sheet, and the mesh sheet material may be mixed with glass fiber, aramid fiber, carbon fiber or the like for preventing extension.

Then, the vertical beam and the horizontal beam of the net-like sheet are melted and joined at the initial stage when extruded as the same material, for example, polypropylene, so that the vertical beam and the horizontal beam are integrated. For joining the reference sheet and the net-like sheet, basically, the reference sheet is joined by a spunlace method (water flow entanglement method) in which non-woven fibers are entangled with a high-pressure water stream.
Furthermore, the space formed by the vertical rail and the horizontal rail of the mesh sheet forms a structure that is difficult to stretch, and a triangular or quadrangular space is desirable. In particular, it has been confirmed by the inventors that, as long as each side of a rectangular space is 15 mm or less, even if a single space independently extends due to the hooking of the reference sheet, there is little deformation as a whole. Further, since the vertical beam and the horizontal beam can be pushed out from the nozzle as a single thread, a triangular or quadrangular space is inexpensive to produce.
Furthermore, since the reference sheet and the mesh sheet are arranged, and the vertical beam and the horizontal beam are integrated by a hydroentanglement process, the nonwoven fabric fibers are wound around the vertical beam and the horizontal beam, Since it is not a partial connection but a two-dimensional or three-dimensional connection, the integration is firm.
Here, what is expressed as the vertical beam and the horizontal beam is a striate body. In the embodiment, the thickness of the line of the vertical beam and the horizontal beam is about 0.05 to 0.1 mm. Yes, at the intersection, it is about 0.2 to 0.5 mm.

The space of the mesh sheet is such that one space is a triangle or a quadrangle.
Here, the vertical beam and the horizontal beam are extruded from the nozzle as a single thread, and a triangular or quadrangular space can be formed by simple nozzle control, so that an inexpensive manufacturing apparatus can be obtained.
Although one space is a triangle or a quadrangle, in the case of carrying out the present invention, any shape that does not expand and contract may be used.

The hydroentanglement process by the spunlace method of the mesh sheet with respect to the reference sheet is performed so that fiber materials gather around the mesh sheet.
Here, in the spunlace method, the nonwoven fabric fibers are sprayed with a water flow, and the reference sheet and the mesh sheet are firmly integrated with the nonwoven fabric fibers intertwined by the sprayed nonwoven fabric fibers.

The method for producing a functional sheet according to the invention of claim 2 comprises a reference sheet processing portion of a reference sheet in which nonwoven fabrics are laminated by a spunbond method, and a vertical beam and a horizontal beam formed by a solid linear body of a synthetic resin, By joining both the vertical beam and the horizontal beam, a mesh sheet processing unit for a mesh sheet having a space at the vertical beam and the horizontal beam, and the mesh sheet surface is disposed on the reference sheet surface, The crosspiece and the horizontal crosspiece are integrated with each other by a water entanglement process.
Here, as the reference sheet formed by laminating the nonwoven fabric of the reference sheet generation processing section by the spunbond method, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyethylene fiber, polypropylene fiber, polyolefin fiber, aramid fiber, rayon Fiber, glass fiber, etc. are used.
Moreover, polyamide, polypropylene, polyethylene, acrylonitrile butadiene styrene, polycarbonate, polystyrene, vinyl chloride, phenol resin, or the like is used as the material of the mesh sheet used in the mesh sheet generation processing unit. Of course, the same material as that of the reference sheet is preferable for the material of the mesh sheet, but glass fiber, aramid fiber, carbon fiber or the like for preventing extension may be mixed into the material of the mesh sheet.

Then, the joining of the vertical beam and the horizontal beam of the mesh sheet generation processing unit is performed by using the same material for the reference sheet used in the mesh sheet generation processing unit and the mesh sheet used in the mesh sheet generation processing unit, and fusing them together. Is desirable. When an adhesive is used, hot melt is suitable, and general low density polyethylene resin and ethylene vinyl acetate resin can be used. Moreover, it is good also as use of copolyamide resin and copolyester resin. Of course, the vertical beam and the horizontal beam may be made of polypropylene, for example, and both may be joined at the initial stage when the molten synthetic resin is extruded.
Furthermore, the space formed by the vertical beam and the horizontal beam of the mesh sheet of the mesh sheet generation processing unit forms a structure that does not easily stretch, and a triangular or quadrangular space is desirable. In particular, the inventors have confirmed that, as long as each side of a rectangular space is 15 mm or less, even if a single space extends independently due to catching, the deformation as a whole is small. Further, since the vertical beam and the horizontal beam can be pushed out from the nozzle as a single thread, a triangular or quadrangular space is inexpensive to produce.
Furthermore, since the reference sheet and the mesh sheet are arranged and the vertical beam and the horizontal beam are integrated by a water entanglement process, the integration of the non-woven fabric is performed by the water entanglement process. It winds around the crosspiece and the horizontal crosspiece, is integrated, and becomes firm.

The functional sheet of the invention of claim 1 is composed of a reference sheet formed of a nonwoven fabric laminated by a spunbond method, and a vertical beam and a horizontal beam formed of a linear body of synthetic resin, both of the vertical beam and the horizontal beam. And a mesh sheet that forms a space surrounded by the vertical beam and the horizontal beam, and the vertical beam and the horizontal beam of the mesh sheet are connected to the reference sheet by hydroentanglement processing. To be integrated.
Therefore, even if the reference sheet made of non-woven fabric is caught due to floor irregularities, undulations, foreign matter adhesion, etc., and partly expands and contracts, dust, hair, solid dust, stains, adhesion on the retained floor When holding foreign objects such as liquid, the mesh sheet protects the reference sheet from being stretched or torn by catching on the floor protrusions or deposits, etc. Dust on the floor, hair, Since foreign matters such as solid dust, stain stains, and attached liquid are not released, it is possible to maintain the foreign matters and prevent them from being scattered. The mesh sheet attached to the reference sheet can suppress expansion and contraction even when the reference sheet is pressed against the floor surface, allowing foreign matter such as dust on the floor, hair, solid debris, stain stains, and adhering liquid to enter. Can be held. In the elastic change of the mesh sheet attached to the reference sheet, the foreign matter once held by the reference sheet is not easily released.

In particular, the space surrounded by the vertical rail and the horizontal rail does not capture foreign matter such as hair, solid waste, stain stain, adhering liquid directly in the space, and by prohibiting the expansion of the space, Since the state of the nonwoven fabric wound around the vertical rail and the horizontal rail of the reference sheet is maintained, even fine dust is not scattered.
Further, if the temperature at the time of joining the reticulated sheet and the reference sheet is set to the temperature in the molten state, both can be joined, so that it is not necessary to use a special binder (adhesive), so that the binder processing can be omitted.
In addition, since the space surrounded by the vertical beam and the horizontal beam becomes a three-dimensional space at the intersection of the vertical beam and the horizontal beam, the mesh sheet becomes a three-dimensional space and further suppresses expansion and contraction of the mesh sheet. can do. Furthermore, since one side of the mesh of the mesh sheet is 15 mm or less, for example, even in uniform floor cleaning, force can be uniformly applied to the entire floor surface, and cleaning without waste can be performed.
Furthermore, when the functional sheet of the present invention is used as a cleaning sheet or the like, it can be cut in consideration of the mesh, and it can be confirmed whether there is no mistake in the interval at which it is cutting.
In addition, the vertical beam and the horizontal beam are striated bodies, and the thickness of the line of the vertical beam and the horizontal beam is about 0.05 to 0.1 mm, and the intersection is about 0.2 to 0.5 mm. Since the absolute area is small, the mesh sheet does not interfere with the function of the reference sheet. In addition, since the volume of the mesh sheet is small, the capacity of the mesh sheet is small, and the reference sheet is not deformed even when melt-bonding.

Since the space formed by the mesh sheet is a triangular or quadrangular space surrounded by the vertical beam and the horizontal beam, the extension of each side is reduced when the space is a triangle . In addition, when the space is square, particularly when one side is 15 mm or less, the extension of each side becomes a three-dimensional distortion, and the deformation of the space can be suppressed .

Water flow entangling treatment of said net-like sheets with respect to the reference sheet, said from the periphery of the net-like sheets in which fibrous material is performed as set, the longitudinal bars and the transverse bars of the mesh sheet by hydroentanglement treatment And the reference sheet can be firmly integrated.

The method for producing a functional sheet according to claim 2 is the intersection of a reference sheet generation processing unit for obtaining a reference sheet formed of a nonwoven fabric by a spunbond method and a vertical beam and a horizontal beam formed of a synthetic resin strip. By joining the vertical rail and the horizontal rail to obtain a mesh sheet in the space surrounded by the vertical rail and the surface of the reference sheet and the surface of the mesh sheet, the spunlace method And an integration process for integrating the vertical beam and the horizontal beam of the mesh sheet with the reference sheet by a water entanglement process.
Therefore, in the reference sheet generation processing section, a reference sheet is formed with a nonwoven fabric by the spunbond method, etc., and this reference sheet is partially expanded and contracted due to floor irregularities, undulations, foreign matter adhesion, etc. Make it possible to remove and capture foreign objects such as dust, hair, solid debris, stains and adhering liquid on the floor. The mesh sheet generation processing unit obtains a mesh sheet in a space surrounded by the vertical beam and the horizontal beam by joining the intersections of both the vertical beam and the horizontal beam. The mesh sheet obtained by the spunlace method formed by the mesh sheet generation processing unit protects the reference sheet from being stretched or torn by catching on the floor protrusions, deposits, etc. Since foreign matter such as dust, hair, solid dust, stain stains and adhering liquid is not released, it is possible to maintain the foreign matter and prevent the foreign matter from being scattered. The mesh sheet attached to the reference sheet can suppress expansion and contraction even when the reference sheet is pressed against the floor surface, allowing foreign matter such as dust on the floor, hair, solid debris, stain stains, and adhering liquid to enter. Can be held.

In particular, the space surrounded by the vertical rail and the horizontal rail does not capture foreign matter such as hair, solid waste, stain stain, adhering liquid directly in the space, by prohibiting the expansion of the space, Since the spunlace method maintains the state of the nonwoven fabric wound around the vertical beam and the horizontal beam of the reference sheet, even fine dust is not scattered.
Further, if the temperature at the time of joining the reticulated sheet and the reference sheet is set to the temperature in the molten state, both can be joined, so that it is not necessary to use a special binder (adhesive), so that the binder bonding process can be omitted.
In addition, since the space surrounded by the vertical beam and the horizontal beam becomes a three-dimensional space at the intersection of the vertical beam and the horizontal beam, the mesh sheet formed by the spunlace method becomes a three-dimensional space, and the mesh sheet Can be further suppressed. Furthermore, since one side of the mesh of the mesh sheet is 15 mm or less, for example, even in uniform floor cleaning, a force sheet can be applied to the entire floor surface, and a functional sheet that can be cleaned without waste is obtained.
Further, the vertical beam and the horizontal beam are striated bodies, and the thickness of the line of the vertical beam and the horizontal beam is about 0.05 to 0.1 mm, and the intersection is about 0.2 to 0.5 mm. In addition, since the absolute area is small, the mesh sheet does not disturb the function of the reference sheet. In addition, since the volume of the mesh sheet is small, the capacity of the mesh sheet is small, and the reference sheet is not deformed even when melt-bonding.

Of course, the reticulated sheet 3 is preferably made of the same material as that of the reference sheet 2, but may be made of a completely different material. In this case, it is also possible to use a mixture of glass fiber, aramid fiber, carbon fiber, or the like for preventing extension as the material of the mesh sheet 3.

Further, for example, when the molding temperature of the mesh sheet 3 is made higher than the molding temperature of the reference sheet 2 to integrate the both, the mesh sheet 3 and a part of the reference sheet 2 are fused. Adhesive and moderate joining is performed.

Further, since the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n can be pushed out from the nozzle as a single thread, the rectangular spaces d ₁ , d _2, ··· d _n the production cost also becomes cheaper.

The vertical rails A ₁ , A ₂ ,... _An are linear rails (wires) extending in parallel with the conveyance direction of the functional sheet manufacturing apparatus described later, and the horizontal rails B ₁ , B ₂ ,. _Bn is a straight bar (wire) extending in a direction perpendicular to the conveying direction of the manufacturing apparatus described later. Vertical bar _{A 1, A 2, ··· A} n nozzles 62 of a predetermined distance, 63 and 64, the nozzle 85, to form a 86 and 87, on the reference sheet 2 by free fall of the molten synthetic resin vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, which is drawn · · · B _n. In addition, the horizontal rails B ₁ , B ₂ ,... B _n are based on a long line in the horizontal direction by opening and closing the gates of the straight holes arranged at right angles to the conveying direction of the manufacturing apparatus at a predetermined timing. It is drawn on the sheet 2. Of course, the vertical bar _{A 1, A 2, ··· A} n and rungs _{B 1, B 2, ··· B} n is a resin made of solid.

Usually, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, intersections of _{··· B n C 1, C 2} , ··· C n , the temperature of both the molding temperature Because of the above, it is fused and united. At this time, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, the · · · B _n, because the thickness of the molten resin is cross-sectional circular or elliptical cross section, both It will be three-dimensionally bonded, that is, unlike a quadrilateral drawn by a line, if tension is applied to one side, twisting occurs and it becomes difficult to stretch. Further, if each side of the rectangular space is 15 mm or less, the tension applied in a specific side direction becomes a force of expansion and contraction and twisting, and as a result, the vertical beams A ₁ , A ₂ ,. _n and the crosspieces B ₁ , B ₂ ,... B _n are difficult to expand and contract.

Vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, intersection C ₁ of _{··· B n, C 2, ···} C n is the temperature of both higher molding temperature There has been described a case where the integral is fused adhesion, adhesion vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, between the · · · B _n with adhesive May be.
That is, a hot melt adhesive is suitable for bonding the reference sheet 2 and the net-like sheet 3, but general low density polyethylene resin and ethylene vinyl acetate resin can also be used. Moreover, it is good also as use of copolyamide resin and copolyester resin. However, when practicing the present invention, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, and · · · B _n, the same material, for example, a polypropylene was extruded Most preferably, the two are melted and bonded in the initial stage.

In any case, the reference sheet 2 and the net-like sheets 3, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, intersections of _{··· B n C 1, C 2} , · in · · C _n, or between the reference sheet 2 and the net-like sheets 3 are fused bonded to each other.
Incidentally, the vertical bar A _1, A ₂ of the present embodiment, · · · A _n and rungs B _1, B _2, intersections of _{··· B n C 1, C 2} , ··· C n , the reference The sheet 2 and the net-like sheet 3 are made of the same material, and their temperature is set to be equal to or higher than the melting point.

Vertical bar A _1, A ₂ of the net-like sheets 3, · · · A _n and rungs B _1, B _2, space d _1, d ₂ formed in ··· B _n, ··· d _n is the space d _1, d _2, hardly elongation · · · d _n, is intended to form a hardly deformed structure, in particular, the space of square _{d 1, d 2, ··· d} n is each side 15mm or less, 3 mm or more if the space d ₁ of a single by snagging nonwoven reference sheet 2, d _2, also extend · · · d _n are independently as a whole, it deformed less is confirmed by the inventors It was. Further, by controlling the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n as a single thread, the rectangular spaces d ₁ , d ₂ , ... d _n can be formed, and the production cost is also low. Here, the space of square d _1, d _2, and that the sides of · · · d _n is not less than 3mm, the cleaning function of the reference sheet 2 is a distance that can be maintained.
The thicknesses of the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n are about 0.05 to 0.1 mm. However, at the intersections of the intersection points C ₁ , C ₂ ,... C _n , it is about 0.2 to 0.5 mm.

Vertical bar _{A 1, A 2, ··· A} n and rungs _{B 1, B 2, ··· B} n is the striatum, the vertical bar _{A 1, A 2, ··· A} n , rung The thickness of the lines B ₁ , B ₂ ,... B _n is about 0.05 to 0.1 mm, and the intersection is about 0.2 to 0.5 mm. Does not interfere with the operation of the reference sheet 2. Further, since the volume of the mesh sheet 3 is small, the heat capacity held by the mesh sheet 3 is small, and the synthetic resin fibers of the reference sheet 2 are not deformed even when melt-bonding.
The above-described embodiments, the space of square d _1, d _2, has been described · · · d _n, the space d △ _1, d △ ₂ triangles shown in FIG. 3, for the · · · d △ _2n It can be formed similarly.
That is, the vertical bar _{A 1, A 2, ··· A} n is a straight line extending in the conveying direction of the manufacturing apparatus, the rungs B _1, B _2, with respect to the conveying direction of the · · · B _n manufacturing apparatus It is a straight line extending in a perpendicular direction. The inclination rungs _{E 1, E 2, ··· E} n is a straight line extending in the direction of 135 degrees with respect to the conveying direction of the manufacturing equipment (45 degrees).

Accordingly, the inclined lateral beam _{E 1, E 2, ··· E} n is set from the vertical bar A ₁ to repeatedly move the distance between the vertical bar A ₂ between the rungs B ₁ and rung B ₂ Thus, it is drawn on the drum to form triangular spaces dΔ ₁ , dΔ ₂ ,... DΔ _2n .
Vertical bar A _1, A ₂ of the net-like sheets 3 of the present embodiment, · · · A _n and rungs B _1, B _2, space d _1, d ₂ formed in ··· B _n, ··· d _n forms a structure that is difficult to stretch, and is preferably a triangle. In particular, the space of square d _1, d _2, if · · · d _n than each side 15mm or less, a single space d _1, d ₂ by caught, even extend · · · d _n is independently As a whole, the inventors have confirmed that there is little deformation. In addition, since the vertical bars A ₁ , A ₂ ,... A _n and the horizontal bars B ₁ , B ₂ ,... B _n of the mesh sheet 3 can be extruded from the nozzle as a single thread, they are triangular or quadrangular. space d _1, d ₂ of, ··· d _n the production cost also becomes cheaper. However, when implementing this invention, it is not limited to the structure of these mesh sheets 3.

Reference sheet 2 formed by the spunbond method, the vertical bar A _1, A ₂ of the net-like sheets 3, · · · A _n and rungs _{B 1, B 2, ··· B} n, the intersection C _1, C ₂ , before the hydroentanglement process 5 · · · C _n, because the temperature is raised above the molding temperature, they are bonded.
However, it has been found that the reference sheet 2 and the net-like sheet 3 can be detached only by applying a large external force and are not joined to each other, so that they are weak against the external force.
Therefore, considering the expansion and contraction of the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n of the mesh sheet 3, the surfaces of the reference sheet 2 and the mesh sheet 3 are considered. And the effect of the water entanglement treatment 5 such as the spunlace method is required.

Specifically, as shown in FIGS. 5 and 7, a manufacturing method will be described for a functional sheet manufacturing apparatus that manufactures the cleaning sheet 1 of the present embodiment.
In the figure, a conveyor 21 including a conveying roller 20a, a conveying roller 20b, and the like sequentially forms the reference sheets 2 by a spunlace method while conveying from the left to the right in the drawing. That is, the first spunlace processing unit 30 for obtaining the reference sheet 2 formed of laminated nonwoven fabrics is formed. In the present embodiment, the spunlace method is used to obtain the reference sheet 2 without using the spunbond method.
The first spunlace processing unit 30 is provided with a spunlace nozzle (nonwoven fabric nozzle) 22 that entangles the aggregate of nonwoven fabric fibers with the reference sheet 2. Since the modification is easy, the cleaning sheet 1 is manufactured using a spunlace method in which fibers are entangled with a high-pressure water stream. In addition, a baffle plate (not shown) and an air nozzle 23 that rectify the air flow are disposed at the inlet of the first spunlace processing unit 30.

The collection tank 25 is a container that collects excess liquid containing excess fibers that have not been used in the reference sheet 2. The liquid containing fibers collected in the collection tank 25 is agitated and contains foreign substances such as dust. The mixture is removed and supplied to a stirring filter 26 that passes only the target fiber. The required amount of fiber and liquid are mixed and supplied by the stirring filter 26.
Fluid consisting of nonwoven fabric fibers and liquid is supplied by pumps 27A and 27B that are independently arranged to circulate the fluid. The pump 27A and the pump 27B that generate a predetermined pressure for supplying the fluid are passed through the pipe line 28 and the pipe line 29, and the first spunlace processing unit 30 or the second spunlace processing unit 40 is allowed to stir the non-woven fiber. Feed the fluid.

The first spunlace processing unit 30 is provided with a plurality of spunlace nozzles 22 at an angle in the length direction (traveling direction) of the conveyor 21. That is, the spunlace nozzle 22 is disposed perpendicular to the traveling direction of the conveyor 21.
That is, jet spray is ejected from the plurality of spunlace nozzles 22 as a row. Thereby, a specific surface of the reference sheet 2 is formed.

At this time, the manifold 32 is disposed in the pipe line 28 of the first spunlace processing unit 30, adjusts the pressure of the spunlace nozzle 22 , and energy of the spunlace method in which the fibers are entangled with the high-pressure water flow between the reference sheet 2. The fiber is entangled with the reference sheet 2 with a high-pressure water flow. Thereby, the position and cross-sectional shape of the reference sheet 2 are specified.
That is, the reference sheet 2 is provided with a hole made of a plurality of round holes on a plane, and in the example shown in FIG. Normally, the manifold 32 and the first spunlace processing unit 30 are integrated.

At this time, the drying roller 34 is disposed at the outlet of the first spunlace processing unit 30 in which the spunlace nozzle 22 is disposed, and is applied to the reference sheet 2 and the reference sheet 2 disposed on one surface of the reference sheet 2. The moisture contained is squeezed and dried, and the moisture on the upper surface of the reference sheet 2 and the reference sheet 2 is removed.
The conveyor 21 conveys the reference sheet 2 to the end thereof, while the outer surface of the large-diameter pulley 50 whose inside is depressurized is sucked and rotated along the large-diameter pulley 50, and the opposite surface is connected to the conveyor 51a. It is transferred to the conveyor 51b and transferred from the right to the left in the drawing.

The reference sheet 2 formed by the first spunlace processing unit 30 placed on the conveyor 21 is inverted by a large-diameter pulley 50, and the vertical rails A ₁ , A ₂ ,. · a _n and rungs B _1, B _2, consists · · · B _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, both of · · · B _n intersection C _1, C _2, by joining · · · C _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, a space surrounded by the · · · B _n The network sheet generation processing unit 60 that obtains the network sheet 3 formed with the process starts.
A synthetic resin fiber of the manifold 61 is pushed out from the nozzles 62, 63, 64 by a sensor (not shown), and the synthetic resin is drawn continuously and at a predetermined interval on the upper surface of the reference sheet 2.

The pressure regulator 45 is disposed in the pipe line 29 of the second spunlace processing unit 40, adjusts the pressure of the spunlace nozzle 44, and adjusts the energy of the spunlace method in which the fibers are entangled with the high-pressure water flow between the reference sheet 2 and the pressure regulator 45. Then, the degree of the process of intertwining the fibers with the reference sheet 2 with a high-pressure water flow is adjusted. Thus, the vertical bar A _1, A ₂ to the reference sheet 2, · · · A _n and rungs B _1, B _2, the position of the · · · B _n, the cross-sectional shape is specified.
The drying roller 46 is disposed at the exit of the second spunlace processing unit 40 where the spunlace nozzle 44 is disposed, and the reference sheet 2 and the vertical rails A ₁ , A ₂ ,. .. The water contained in A _n and the horizontal bars B ₁ , B ₂ ,... B _n is squeezed and dried. In addition, a baffle plate (not shown) and an air nozzle 42 that rectify the air flow are provided.

As a result, the reference sheet 2 is U-turned by the large-diameter pulley 50, and the vertical beams A ₁ , A ₂ ,... _An and the horizontal beams B ₁ , B ₂ ,. ... entering the formation of B _n. Basically, since the surface of the reference sheet 2 is reversed by the large-diameter pulley 50, the vertical beams A ₁ , A ₂ ,... _An and the horizontal beams B ₁ , B ₂ ,. · B _n the intertwining earlier, the formation of the opposite surface.
The pressure regulator 45 is disposed in the pipe line 29 of the manifold 61, adjusts the pressure of the spunlace nozzle 44, and uses the energy of the spunlace method in which fibers are entangled with the high-pressure water flow between the reference sheet 2 and the first span of the conveyor 21. The lace processing unit 30 and the second span lace processing unit 40 of the conveyor 51 are adjusted independently.

Therefore, when the reference sheet 2 is introduced from the outside into the first spunlace processing unit 30, jet spray is ejected from the spunlace nozzle 22, and the first spunlace processing unit 30 between the conveyors 21 forms the reference sheet 2. It becomes the process which a fiber is entangled with the reference | standard sheet | seat 2 by the high-pressure water flow between nonwoven fabric fibers. That is, jet spray is sprayed from the spunlace nozzle 44, and the reference sheet 2 is entangled with the reference sheet 2 by the high-pressure water flow between the reference sheet 2 and the nonwoven fabric fibers in the second spunlace processing unit 40 between the conveyors 41. 2 is a process in which the mesh sheet 3 is entangled. Second spunlace processing section 40, the vertical bar A _1, A ₂ formed by a solid-like striatal synthetic resin, · · · A _n and rungs B _1, B _2, consists · · · B _n , vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , by joining · · · C _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, space surrounded by _{··· B n d 1, d 2} , ··· d n, d △ 1, d △ 2 ,..., DΔ _2n is obtained.

The functional sheet manufacturing method of the present embodiment is formed by a net-like sheet generation processing unit 60 that obtains the reference sheet 2 formed of the nonwoven fabric laminated by the first spunlace processing unit 30 and a solid filament of synthetic resin. vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, consists · · · B _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , by joining · · · C _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, ... A mesh sheet generation processing unit 60 for obtaining a mesh sheet 3 in which a space surrounded by B _n is obtained; _1, a _2, ··· a _n and rungs B _1, B _2, those comprising the integrated process for integrating · · · B _n in the standard sheet 2 and spunlace That. Here, the integrated processing means that the vertical beams A ₁ , A ₂ ,... _An and the horizontal beam B ₁ , of the mesh sheet 3 by the water entanglement processing 5 by the span lace method by the first span lace processing unit 30 . B ₂ ,... B _n are integrated with the reference sheet 2, and corresponds to the water entanglement process 5 and the span lace processing part 97 by the second span lace processing part 40 after passing through the mesh sheet generation processing part 60.

Here, the reference sheet 2 is formed of the nonwoven fabric laminated by the spunlace method in the first spunlace processing unit 30 as the reticulated sheet generation processing unit 60. The reticulated sheet generation processing unit 60 that forms the reference sheet 2 by the spunbond method is not limited thereto.
That is, when the reference sheet 2 is formed, it means that the spunlace method, the spunbond method, or another method may be used.

Furthermore, the manufacturing method is demonstrated about the other example of the functional sheet manufacturing apparatus shown in FIG.6 and FIG.7 of the cleaning sheet 1 of this Embodiment formed in this way.
A reference sheet 2 formed by a spunbond method is supplied from the outside of the drawing apparatus. The reference sheet 2 may have a plate shape or a pattern, but a web shape as a network network of a nonwoven fabric is usually formed.

A net forming pulley 83 formed of a stainless steel plate of the cleaning sheet 1 as the functional sheet 6 of the present embodiment includes vertical bars A ₁ , A ₂ ,... _An and horizontal bars B ₁ , B ₂ ,. A manifold 84 and nozzles 85, 86, 87 forming B _n are disposed at the highest portion, and the vertical beam A ₁ , A ₂ ,... _An and the horizontal beam B ₁ , B are formed on the surface of the mesh forming pulley 83. ₂ ... B _n is drawn. Vertical bar A _1, A ₂ drawn, · · · A _n and rungs _{B 1, B 2, ··· B} n, the intersection C _1, C _2, figure · · · C _n is the net forming the pulley 83 It is formed in an annular shape, and is moved from the periphery of the net forming pulley 83 to the upper surface of the reference sheet 2 at the lowermost part of the net forming pulley 83.
By the tension rollers 88a and 88b, the reference sheet 2 and the net-like sheet 3 to which a predetermined tension is applied are overlapped. That is, the vertical bars A _1, A ₂ on the upper surface of the web forming the pulley 83, · · · A _n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , ··· C by joining _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, space surrounded by the · · · B _n intersections C _1, C _2, ··· C Processing of the mesh sheet generation processing units 60 and 80 for obtaining the mesh sheet 3 on which _n is formed is performed. Reticulated sheet generation processing unit 60 and 80, the vertical bar A _1, A ₂ formed by the solid of the striatum of the synthetic resin, · · · A _n and rungs B _1, B _2, consists · · · B _n , vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , by joining · · · C _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, space surrounded by _{··· B n d 1, d 2} , ··· d n, d △ 1, d △ 2 ,..., DΔ _2n is obtained.

Around the mask drum 90, the homogeneous reference sheet 2 is conveyed from the left to the right as shown in FIG. 6 by the tension roller 88a and the tension roller 88b so as to rotate along the outer periphery. Around the mask drum 90, the reference sheet 2 and the reticulated sheet 3 are rotated at the same speed as the outer periphery of the mask drum 90 in an angle range of 200 to 270 degrees.
Mask drum 90 formed by a stainless steel plate of the cleaning sheet 1 of the present embodiment, the vertical bar A _1, A ₂ shown in FIG. 2, · · · A _n and rungs B _1, B _2, · · · B _n , intersections C ₁ , C ₂ ,... C _n are formed as through holes formed in an annular shape, and constitute a spunlace processing portion 97.

That is, the end of the mask drum 90 is closed, and a manifold 92 connected to the conduit 91 is disposed there. The pressure in the pipe 91 and the manifold 92 (not shown) is adjusted by adjusting the pressure of the spunlace nozzle 93 by a pressure regulator (not shown) and adjusting the energy of the spunlace method in which fibers are entangled with the high-pressure water flow between the reference sheet 2 and the pipe 91. The fiber is entangled with the reference sheet 2 with a high-pressure water flow. Thus, the vertical bar A _1, A ₂ to the reference sheet 2, · · · A _n and rungs B _1, B _2, the position of the · · · B _n, the cross-sectional shape is specified.
Below the mask drum 90, a collection tank 94 for collecting excess liquid after the nonwoven fabric fibers are entangled with the reference sheet 2 by high-pressure water flow is disposed. A stirring filter 95 is connected to the collection tank 94, and a necessary amount of nonwoven fabric fibers and liquid are mixed, and a fluid comprising the short fibers and liquid is supplied by a pump 96 that circulates the fluid.

A pump 96 that generates a predetermined pressure passes through the conduit 91 and supplies the manifold 92 with the required amount of nonwoven fibers and liquid. From this spunlaced nozzle 93 is always injected jet spray, vertical bars A _1, A ₂ by the short fibers within a predetermined angle range passes through the through holes of the mask drum 90, · · · A _n and rungs B ₁ , B ₂ ,... B _n are intertwined by the spunlace treatment section hydroentanglement process 5. At this time, the injection from the jet spray, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, the position of the · · · B _n becomes denser, also increased its mass It becomes a relatively highly elastic mass. As a result, the non-woven fabric near the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n has a dense fiber density and a large mass. Since the fiber density of the reference | standard sheet | seat 2 and the net-like sheet | seat 3 can be formed high, the absorption and holding | maintenance capability of a liquid become large by capillary action.

Therefore, the mask drum 90, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, because the through-hole to form a · · · B _n are formed, always span Jet spray is sprayed from the lace nozzle 93 , and the spunlace processing unit 97 in the mask drum 90 causes the reference sheet 2 to be entangled with the reference sheet 2 by the high-pressure water flow of the nonwoven fabric fibers.
The figure shown in FIG. 2 is drawn as a through hole in the annular mask drum 90 so that the reference sheet 2 rotates at the same speed as the mask drum 90 along the periphery of the mask drum 90 around the mask drum 90. Furthermore, the tension roller 88a and the tension roller 88b move at a constant speed. That is, the shape of the reference sheet 2 is transferred to the reference sheet 2 around the mask drum 90 because the reference sheet 2 is at the same speed as the outer periphery of the mask drum 90 by the tension roller 88a and the tension roller 88b.

Thus, the jet spray is injected from spunlace nozzle 93 through the through holes of the mask drum 90, the vertical bar A ₁ from fibers intertwined standard sheet 2 and the net-like sheets 3 with a high pressure water flow between the non-woven fibers, A _2, · · · a _n and rungs B _1, B _2, the density of only the position of · · · B _n increases, its mass also increases. At this time, the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n have a shape close to a lump, and the reference sheet is peeled off from the mask drum 90 in the meantime. On the floor side of 2, a low-density, low-mass foreign material passage is formed by the line spacing.
Also for the cleaning sheet 1 as the functional sheet 6 of this embodiment, the vertical beams A ₁ , A ₂ ,... _An and the horizontal beam B ₁ so that the nonwoven fabric fibers are intertwined with the reference sheet 2 by high-pressure water flow from one side. , B ₂ ,... B _n . In addition, the mesh sheet 3 in the vertical bars A ₁ , A ₂ ,... _An and the horizontal bars B ₁ , B ₂ ,... B _n has a high density of non-woven fibers and a large mass. Therefore, since the fiber density of the reference sheet 2 can be formed high, the ability to absorb and retain the liquid increases due to capillary action.

Cleaning sheet 1 as a functional sheet 6 of the above embodiment, further, the long side of the reference sheet 2 to the long side of the cleaning body surface 15 of the cleaning tool 10, the short cleaning body surface 15 of the cleaning tool 10 since those mounted in association with the short side of the reference sheet 2 side, which attach the long side of the reference sheet 2 to the cleaning unit body surface 15 of the cleaning tool 10, the cleaning unit body surface 15 of the cleaning tool 10 You can definitely perform the installation on.

The functional sheet 6 of the above embodiment includes a reference sheet 2 formed of laminated nonwoven fabrics, vertical bars A ₁ , A ₂ ,... _An and horizontal bars B ₁ , formed of a synthetic resin solid filament. B _2, consists · · · B _n, vertical bar _{a 1, a 2, ··· a} n and rungs B _1, B _2, the intersection of both _{··· B n C 1, C 2} , ·· - joined with C _n, vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, space surrounded by _{··· B n d 1, d 2} , ··· d n _{, d △ 1, d △ 2} , ··· d △ 2n features arranged a net-like sheet 3 formed with, vertical bars a ₁ of net-like sheets 3 by hydroentanglement process 5, a _2, ··· a _n And the crosspieces B ₁ , B ₂ ,... B _n are integrated with the reference sheet 2.

  Therefore, the reference sheet 2 formed of nonwoven fabric is partially expanded and contracted due to unevenness of the floor, undulations, adhesion of foreign matters, etc., and dust, hair, solid dust, stain stains, adhering liquid, etc. on the retained floor When the foreign material is removed and captured, the mesh sheet 3 protects the reference sheet 2 from being caught by protrusions and deposits on the floor and extending or torn, and the dust, hair, Since foreign matters such as solid dust, stains and adhering liquid are not released, it is possible to maintain the foreign matters and prevent them from being scattered. The net-like sheet 3 provided alongside the reference sheet 2 can suppress expansion and contraction even when the reference sheet 2 is pressed against the floor surface, and can remove foreign matter such as dust, hair, solid dust, stains, and adhering liquid on the floor. You can dive and hold.

In particular, the vertical bar _{A 1, A 2, ··· A} n and rungs B _1, B _2, space d _1, d ₂ surrounded by _{··· B n, ··· d n,} d △ 1, d △ _2, ··· d △ _2n, the space _{d 1, d 2, ··· d} n, d △ 1, d △ 2, directly hair, solid garbage ··· d △ _2n, stains dirt, not to capture foreign matters such as deposition liquid, the space _{d 1, d 2, ··· d} n, d △ 1, d △ 2, by inhibiting the growth of · · · d △ _2n, reference sheet 2 vertical bar a _1, a ₂ of, · · · a _n and rungs B _1, B _2, since it is intended to maintain the state of the nonwoven fabric wound around the · · · B _n, with reference sheet 2 fine after capture Even dust will not scatter them.
In addition, if the temperature at the time of joining the reticulated sheet 3 and the reference sheet 2 is set to a molten temperature, the two can be joined. Therefore, it is not necessary to use a special binder in the bonding process 4. Can be omitted.

The reticulated sheet 3 obtained by the spunlace method formed by the reticulated sheet generation processing unit 60 protects the reference sheet from being stretched or torn by being caught on floor protrusions or deposits, and retained during operation. Since foreign matter such as dust on the floor, hair, solid debris, stain stains, and attached liquid is not released, it is possible to maintain the foreign matter and prevent the foreign matter from being scattered. The net-like sheet 3 attached to the reference sheet 2 can suppress expansion and contraction even when the reference sheet is pressed against the floor surface, and foreign matter such as dust on the floor, hair, solid debris, stain stains, adhering liquid, etc. can be trapped in the floor. Can be held.
