Description

  The present invention relates to a cleaning tool and a knitting device. For example, in a kitchen or a bathroom, each object includes a surface portion of a dirty sink or bathtub, and a surface portion of a small object such as dirty tableware or a cooking utensil. The present invention relates to a cleaning tool for removing dirt from an object by rubbing against the object, and a knitting device for the cleaning tool.

  Conventionally, a cloth-like body is formed by using a synthetic resin film tape subjected to metal vapor deposition such as aluminum as a thread-like fiber, and this is used as a cleaning tool like "scouring". (Hereinafter, the cloth-like body having such a configuration is also expressed as scouring). Since the synthetic resin film tape is strip-shaped, rubbing it with its corners in contact with the object to be cleaned can scrape off the dirt, so it was formed using this synthetic resin film tape. Scourers have better cleaning ability than common sponges.

Further, Patent Document 1 discloses that coloring is performed by forming a multicolored coating film on the surface of a soft synthetic resin film such as nylon so that fading due to wear is suppressed as much as possible. In Patent Literature 2, a film tape is wound around a film tape so as to be entangled with a long fiber, and the film tape is piled, so that the film tape can have a soft feeling and can withstand excessive tension. It has been shown to be
JP-A-5-305048 JP-A-8-280594

  However, since the conventional scourer uses soft synthetic resin, the strength of the film tape itself is not sufficient, and it softens further when heat is applied. For example, it is sufficient when cleaning dishes and utensils using hot water. There were times when it was not possible to demonstrate the power. In addition, since the film tape is strip-shaped, even if a pile portion is formed, depending on the angle, the smooth curved surface of the film tape may come into contact with the surface of the object to be cleaned. Sometimes it was not enough.

  Furthermore, even if the film tape is colored, the coloring by a single color can only be colored to one color as a whole. Moreover, even if the film tape is colored with a plurality of different colors, it is only possible to form an irregular pattern, and it is extremely difficult to make a meaningful picture.

  The present invention has been made in consideration of the above-mentioned matters, and the purpose of the present invention is to provide an excellent fashionable cleaning that can exhibit excellent cleaning ability by contacting the surface of an object so as to remove dirt. It is to provide a tool and a knitting device.

  In order to achieve the above object, the cleaning tool according to claim 1 includes a cloth-like body that removes dirt from the object by rubbing against the object, and the cloth-like body includes at least a belt-like fiber made of polyethylene terephthalate. It has a PET pile portion formed by knitting while twisting. In addition, as for the thickness of the strip shaped fiber which consists of a polyethylene terephthalate, it is desirable that it is 30-50 micrometers and a width | variety is 0.75-0.87 mm.

  The cleaning tool according to claim 2, comprising a cloth-like body knitted in a circular knitting manner that removes dirt from the object by rubbing against the object, and a sponge material housed in the cloth-like body. The body has a PET pile portion formed by braiding at least a belt-like fiber made of polyethylene terephthalate, and a sponge material is accommodated inside the cloth body with the PET pile portion facing the front. It is characterized in that a sponge material is sealed in a cloth-like body. The cloth-like body is preferably wide enough to fit in the palm of a person.

  The band-like fiber made of at least polyethylene terephthalate may be a polyethylene terephthalate film adhered with a colored resin film (claim 3). It is desirable to use a colored resin film that has been processed with a special color (hereinafter, this special color is called aurora) coated with a plurality of colors so as to reflect different colors depending on the angle.

  The band-like fiber made of at least polyethylene terephthalate may be a polyethylene terephthalate film deposited with a metal (Claim 4). As the metal to be deposited, it is desirable to use, for example, silver, copper, gold, aluminum or the like.

  A pattern may be formed by partially providing the PET pile portion.

  The cloth-like body may have an acrylic pile portion formed by weaving fibers made of acrylic.

  The cloth-like body may have a fiber pile portion formed by weaving fibers made of microfibers (Claim 7).

  The knitting apparatus according to claim 8, comprising a PET pile portion formed by weaving a belt-like fiber made of polyethylene terephthalate into a cloth-like body, and cleaning the object by rubbing against the object. Is a circular knitting machine for circular knitting, and is arranged downstream of the yarn feeder for supplying fibers for forming a pile to the knitting needles arranged in an annular shape so as to knit the cloth-like body And a pile knitting cam for forming the pile using the fiber, and a control unit for controlling the formation of the pile by the pile knitting cam. Further, it is desirable that the yarn feeding port of the belt-like fiber is provided with a twisting mechanism for feeding yarn while twisting the fiber.

  A plurality of sets of yarn feeders and pile knitting cams may be provided in different phases with respect to the annularly arranged knitting needles, and each pile knitting cam may move independently ( Claim 9).

  The control unit may include a storage unit that stores a pattern of a cleaning tool, and a pile instruction unit that instructs a pile length of the pile knitting cam in accordance with a position of the pile knitting cam. ).

  According to the cleaning tool of claim 1, polyethylene terephthalate (hereinafter abbreviated as PET) does not soften at the temperature of hot water used in kitchen work or bathroom, and can maintain sufficient strength. It is a synthetic resin. Therefore, even when cleaning is performed using hot water, dirt can be easily scraped off by the corners of the PET pile portion. Further, since the belt-like fibers made of PET (hereinafter referred to as PET fibers) are knitted while being twisted, the corners of the PET fibers draw a spiral, and the PET pile portion is also in the contact portion with the object to be cleaned. Twist and the corners come into contact with the object to be cleaned. That is, regardless of the direction in which the PET pile part comes into contact with the object to be cleaned, dirt on the surface can be scraped off by the corners of the PET fiber, and the cleaning ability is improved.

  In addition, by setting the thickness of the PET fiber to 30 to 50 μm and the width to 0.75 to 0.87 mm, the PET fiber can have appropriate hardness and flexibility. As a result, dirt can be scraped off using the PET fiber, and it can be formed into a moderately flexible thread shape that can be used as a fiber.

  According to the cleaning tool of claim 2, in addition to the above effects, the detergent can be absorbed and stored in the cleaning tool by using the water absorption power of the sponge material, so that the object can be stored more efficiently. You can clean things. Further, since the circularly knitted cloth-like body is cylindrical, it is only necessary to sew two sides in order to store the sponge material inside, and the labor required for sewing can be minimized. . It is easy to use for cleaning an object because the width of the cloth-like body fits in the palm of a person.

  In the case where the belt-like fiber composed of at least polyethylene terephthalate is obtained by sticking a colored resin film to a polyethylene terephthalate film (Claim 3), the PET fiber can be arbitrarily colored. In addition, since the resin film colored in advance is stuck, the colored part can be protected by both films by sticking the colored part inside both the films. In other words, the same brightness can be maintained forever by preventing discoloration and peeling. In particular, by using a resin film that has been subjected to an aurora process, a special shine can be imparted, so that a special texture can be maintained for a long time.

  In the case where the belt-like fiber made of at least polyethylene terephthalate is a polyethylene terephthalate film deposited with metal (Claim 4), the PET fiber can have a metallic texture. Moreover, if the metal to vapor-deposit is silver and copper, the antimicrobial function by silver and copper can be given to PET fiber. Further, if the metal to be deposited is gold, it has a high-class feeling, and it can be made difficult to peel off because it is resistant to chemical reaction. When the metal to be deposited is aluminum, the production cost can be kept low.

  In the case where a pattern is formed by partially providing the PET pile part (Claim 5), an arbitrary pattern can be easily formed on the cleaning tool by changing the presence or absence of the pile part and its length. be able to. In other words, the color and texture of the fibers constituting the pile portion are emphasized by the length of the pile portion, and the color of the base fabric of the cloth-like body is emphasized by not providing the pile portion (minimizing the pile length). Therefore, by increasing the length of the pile portion at an arbitrary position of the cleaning tool, an arbitrary pattern can be formed on the cloth-like body depending on the color and texture of the fiber.

  When the cloth-like body has an acrylic pile portion formed by weaving fibers made of acrylic (Claim 6), acrylic has a property of adsorbing to dirt components and is softer than PET fibers. The touch is improved, and the object can be made less likely to be damaged by the cushioning property of the acrylic pile portion. In addition, since acrylic is easily dyed and hardly discolored, the cleaning tool can be easily colored by the acrylic pile portion.

  In the case where the cloth-like body has a fiber pile portion formed by weaving fibers made of microfibers (Claim 7), dirt can be scraped off using each microfiber of the microfibers. The cleaning ability can be increased.

  According to the knitting device shown in claim 8, it is possible to easily knit a cylindrical cloth-like body formed by forming a pile portion at a predetermined position. In particular, when a fiber supplied to the yarn feeder is knitted, a pile can be formed by a pile knitting cam. By controlling this pile knitting cam by a control unit, the presence or absence of a pile in an arbitrary portion and its The length can be changed, and some pattern such as a stripe or check can be formed. Moreover, when the yarn feeding port of the belt-like fiber is provided with a twisting mechanism for feeding the yarn while twisting the fiber, the cleaning ability of the formed cleaning tool can be enhanced.

  A case in which a plurality of sets of the yarn feeder and the pile knitting cam are provided in different phases with respect to the annularly arranged knitting needles, and each pile knitting cam moves independently (claim) In 9), different fibers can be supplied to each pile knitting cam, and the fibers forming the pile at an arbitrary portion can be easily switched. Therefore, a pattern such as a stripe or a check can be formed by changing the fibers constituting the pile.

  The control unit includes a storage unit that stores a pattern of a cleaning tool, and a pile instruction unit that instructs a pile length of the pile knitting cam in accordance with the position of the pile knitting cam (Claim 10). In addition to simple patterns such as stripes and checks, an arbitrary pattern such as a polka dot pattern or some pattern can be formed on the cleaning tool. By adjusting the length of the pile, it is also possible to finely adjust the degree of emphasis on the color and texture of the fibers that make up the pile part. Color and texture can be arbitrarily formed.

  FIG. 1 is a diagram showing a configuration of a cleaning tool 1 according to a first embodiment of the present invention. The cleaning tool 1 according to the present embodiment is a cloth-like body that removes dirt from an object by rubbing the object. A base fabric 2 formed by knitting, a PET pile portion 4 formed by twisting a strip-like PET fiber 3 made of PET against the base fabric 2, and a fiber 5 made of acrylic (hereinafter referred to as other fibers) Acrylic pile portion 6 formed by weaving and fiber 7 made of microfiber (hereinafter referred to as fiber fiber 7 when it is necessary to distinguish from other fibers). And a fiber pile portion 8 formed by weaving.

  Each pile part 4,6,8 is formed in the rhombus area | region a1-a4, respectively. In addition, only the PET pile portion 4 is formed in the region a1, and both the acrylic pile portion 6 and the PET pile portion 4 are formed in the region a2, but the PET pile portion 4 is formed shorter than the acrylic pile portion 6. Therefore, the color and texture of the acrylic fiber 5 appear on the table as a whole. In the region a3, both the fiber pile portion 8 and the PET pile portion 4 are formed. However, since the PET pile portion 4 is formed short, the color and texture of the fiber fiber 7 appear on the table as a whole. . In the region a4, all the pile portions 4, 6, and 8 are formed, but the PET pile portion 4 is formed shorter than the other pile portions 6 and 8, and the colors of the acrylic fibers 5 and the fiber fibers 7 are formed. And the texture is mixed.

  That is, the cleaning tool 1 configured as described above has pile portions 4, 6, and 8 formed on the entire surface, but the pile is applied to each of the regions a 1 to a 4 corresponding to the pile portions 4, 6, and 8. By switching the constituent fibers 3, 5 and 7 (in other words, partially changing the length of the pile formed by the fibers 3, 5 and 7 having different colors and textures) I'm drawing a pattern.

  FIG. 2 is a diagram for explaining the configuration of the PET fiber 3 and the manufacturing method thereof. In FIG. 2, 3A and 3B are, for example, resin films that serve as raw materials for the PET fibers 3, and 9A and 9B are pressure rollers for bonding these resin films 3A and 3B, for example, by heat fusion to form a film 3 '. It is.

  That is, the film 3 'is formed by sticking the aurora film 3B made of a synthetic resin having a thickness d2 of 18 μm, for example, to a film 3A made of polyethylene terephthalate having a thickness d1 of 12 μm, for example. The aurora film 3B is coated with a plurality of colors, for example, and is subjected to aurora processing 3a, and both films 3A and 3B are adhered so that the aurora processing 3a is on the inside. Then, the film 3 ′ on which the both films 3 </ b> A and 3 </ b> B are adhered is cut into a strip shape having a width of 0.75 mm, for example, to become the PET fiber 3.

  Since the PET fiber 3 configured as described above is inside the aurora processing 3a protected by the resin films 3A and 3B, the brightness does not deteriorate, and the appearance is deteriorated due to color baldness or the like as in the past. There is nothing. That is, the PET fiber 3 can always shine differently depending on the angle like an aurora. Further, since PET does not soften at a hot water temperature that is used for cleaning a cleaning object at home, it is possible to easily scrape off the dirt adhering to the object. That is, it is possible to remove dirt from the object by rubbing it against the object using the cleaning tool 1 of the present invention, but by washing the dirt together with a fluid such as water or hot water. The detergency can be further increased.

  Moreover, the aurora processing 3a of the PET fiber 3 shown in the present embodiment is, for example, shining in seven colors based on yellow. The PET fibers 3 are not limited to those subjected to the aurora processing 3a, and may be metal-deposited. In this case, it is not necessary to attach another film to the PET film 3A, and the manufacturing cost can be reduced. However, a film for protecting the metal deposition surface may be attached. Moreover, you may perform both metal vapor deposition and aurora film 3B sticking.

  On the other hand, when metal deposition is performed on the PET fiber 3, it is possible to provide an additional function of metal by exposing the metal deposition surface to the surface. That is, the PET fiber 3 on which a metal such as copper or silver is deposited has a bactericidal power.

  In any case, when the PET fiber 3 has a thickness of 30 to 50 μm and a width of 0.75 to 0.87 mm, the PET pile portion 4 can have appropriate hardness and flexibility as the cleaning tool 1. it can.

  In the cleaning tool 1 of the present invention, the PET fibers 3 configured as described above are knitted into the base fabric 2 while being twisted. Accordingly, the corner portion of the PET fiber 3 has a spiral twist, and the PET pile portion 4 can be uniformly contacted with the object by this twist, and the dirt can be scraped off. Has been. (Refer to FIG. 5 described later)

  The acrylic fiber 5 is dyed yellow, for example. The acrylic fiber 5 has flexibility and water absorption, and has a characteristic that it is easily dyed and does not easily lose color. That is, since the acrylic pile portion 6 is superior in water absorption compared to the PET pile portion 4, the region including the PET pile portion 4 around the region a1 where only the PET pile portion 4 is formed as in this embodiment. By arranging a2 and a4, it is possible to absorb detergent and improve the cleaning ability.

  Further, in the regions a2 and a4 including both the acrylic pile portion 6 and the PET pile portion 4, the acrylic pile portion 6 first comes into contact with the object and then the PET pile portion 4 comes into contact with the object. Can be made softer. That is, this can be protected so as not to damage the object.

  The fiber fiber 7 is dyed in an egg color, for example. The fiber fiber 7 not only has some water absorption, but each fine fiber constituting the fiber fiber 7 is rubbed against the surface of the object so that the dirt can be easily removed. Further, since the fiber fiber 7 is dyed in a slightly lighter color than the acrylic fiber 5, the region a3 can be colored with an egg color. The region a4 can be an intermediate color between the acrylic fiber 5 and the fiber fiber 7.

  That is, the cleaning tool 1 of the present embodiment has a check pattern by forming a dark portion, a thin portion, and a bright portion like an aurora in a roughly rhombus shape based on yellow. And this pattern has both fashion and functionality.

  FIG. 3 is a diagram conceptually showing the configuration of a knitting device 10 for circular knitting the cleaning tool 1. In FIG. 3, reference numeral 11 denotes a knitting needle arranged in a ring so as to knit the cloth-like body 2, and 12 to 14 supply three fibers 3, 5, 7 for forming a pile to the knitting needle 11, respectively. The yarn feeders 15 to 17 are arranged on the downstream side of the yarn feeders 12 to 14, respectively, and pile knitting cams for forming the pile portions 4, 6, 8 using the fibers 3, 5, 7, 18 Is a control unit for controlling the formation of piles by the pile knitting cams 15-17.

  For example, the knitting needle 11 is arranged so that the knitting portion 11a has a circular shape with a diameter of 3 to 4 inches (7.6 to 10.2 cm), and the polyester yarn (not shown) is used as the basis of the cloth-like body 2. A large number are arranged so as to be knitted to form a structure. The sets of the yarn feeders 12 to 14 and the pile knitting cams 15 to 17 are rotated with respect to the knitting needle 11 so that the pile portions 4, 6, and 8 can be knitted into the cloth-like body 2. It is configured.

  The yarn feeder 12 is formed with a twisting mechanism for feeding the PET fiber 3 while twisting it, whereby the PET fiber 3 constituting the PET pile portion 4 is twisted so that the corners are spiral. It is configured.

  Each of the pile knitting cams 15 to 17 is knitted with three different yarns, and therefore is arranged with a phase difference of 120 ° from each other. , 5 and 7 and the pile length 4, 6 and 8 and the pile length can be adjusted independently. The numbers of the yarn feeders 12 to 14 and the pile knitting cams 15 to 17 are provided according to the number of fibers 3, 5 and 7 to be knitted. Therefore, when four fibers are knitted, the interval between the yarn feeders 12 and the pile knitting cams 15 is 90 °, and in the case of two fibers, it is 180 °.

  The configuration of the control unit 18 may be variously modified. For example, the storage unit 18a that stores a pattern 19 desired to be formed on the cleaning tool 1 and the pile positions of the pile knitting cams 15 to 17 are set in accordance with each pile. A pile instruction unit 18b that indicates the pile length (that is, a pile is not formed when the length is 0) by independently controlling the knitting cams 15 to 17, and the storage unit 18a. A central processing unit 18c for controlling the pile instruction unit 18a so as to be a handle 19 is provided.

  The pile instruction section 18b or the pile knitting cams 15 to 17 are for reading the rotational position of a set of yarn feeders 12 to 14 and pile knitting cams 15 to 17 (hereinafter referred to as a pile knitting mechanism P). Although a positioning mechanism such as a rotary encoder or a potentiometer is provided, various configurations are conceivable for this positioning mechanism.

  By using the knitting device 10 described above, the cleaning tool 1 having an arbitrary pattern can be formed. Therefore, in FIGS. 1 and 2, the cleaning tool 1 shows an example in which the handle is a check, but the present invention is not limited to this point, and various forms such as a stripe, a polka dot pattern, and an arbitrary pattern can be considered. It is done. Needless to say, the colors and properties of the fibers 3, 5, and 7 are not limited to those described above. It is also possible to form a clear pattern by combining a plurality of fibers of completely different colors such as the three primary colors. If only the PET pile portion 4 is included, the acrylic pile portion 6 and the fiber pile portion 8 may be omitted.

  FIG. 4 is a view showing a configuration of the cleaning tool 20 of the second embodiment formed by further processing the cleaning tool 1. That is, the cleaning tool 20 shown in FIG. 4 has a flat sponge material 21 (sponge) accommodated in the cleaning tool 1.

  As shown in FIG. 4 (A), the cylindrical cleaning tool 1 is cut into an appropriate length and sewn at one end 1a to form a bag. Next, with the pile portions 4, 6, 8 facing the front, the sponge 21 is accommodated in the bag, and the other end 1b is sewn. FIG. 4 (B) is a diagram showing a configuration of the cleaning tool 20 having excellent water absorption, in which the sponge 21 is housed.

  In the cleaning tool 20 shown in FIG. 4B, since the sewing portions 22 and 23 are only two, the manufacturing process of the cleaning tool 20 can be simplified as much as possible. That is, the manufacturing cost of the cleaning tool 20 can be reduced. Further, the object can be easily cleaned by causing the sponge 21 to absorb detergent or the like.

  FIG. 5 is a partially enlarged view showing a state in which the cleaning tool 20 configured as described above (the same applies to the cleaning tool 1) is rubbed against the dish 25 as a cleaning object. As shown in the enlarged view of FIG. 5, in the cleaning tools 1 and 20 of the present invention, since the PET fibers 3 constituting the PET pile portion 4 are knitted while being twisted, the corner portions 3b of the PET fibers 3 are spiraled by this twisting. It is twisted to draw.

  Therefore, in the example shown in FIG. 5, since at least three corners 3b contact the surface of the dish 25 for one pile, the dirt adhering to the surface of the dish 25 can be easily scraped using these corners 3b. Can be taken. Moreover, since the corner | angular part 3b contacts the surface of the dish 25 at all angles, even if the cleaning tools 1 and 20 are moved to which direction, the dirt on the surface of the dish 25 can be scraped off. And since the PET fiber 3 is elastically deformed, it has an appropriate elasticity, can keep the spiral shape of the corner 3b, and does not soften at a temperature that can touch the user. Therefore, sufficient performance can be exhibited even if cleaning with hot water is performed.

  Further, in the cleaning tool 20 shown in FIG. 5, a meaningful pattern 26 is formed on the surface. That is, by controlling the presence and length of the pile portions 4, 6, and 8 as in the present invention, the pile portions 4, 6, and 8 are partially provided, or the fibers that constitute the pile portions 4, 6, and 8 Since patterns 3, 5, and 7 are partially changed to form a pattern, the cleaning tools 1, 20 of the present invention can form any pattern that is impossible at all with the pile parts 4, 6, 8. can do.
