DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a highly entangled absorbent cotton material used for cosmetic cosmetic cotton, body shape correction cotton for wearing Japanese clothes, wipe cotton for infants, and the like.

[0002]

2. Description of the Related Art Conventionally, in cotton products for cosmetics and cosmetics, in addition to mere laminated absorbent cotton products, a resin or high-pressure water is sprayed and sprayed on the surface with a nozzle in order to suppress fuzz on only the surface. There have been absorbent cotton products that have been attached, or absorbent cotton products in which the front and back surfaces of laminated absorbent cotton are wrapped with a nonwoven fabric material to suppress the fluff on the surface.

[0003]

However, in the case of a mere laminated absorbent cotton product, the surface has fluffing, and the cotton fiber on the surface easily adheres to the skin and easily loses shape especially during use for cosmetics. In addition, cotton fibers tended to adhere to the kimono during use for wearing kimono.

An absorbent cotton product sprayed and sprayed with resin or high-pressure water on its surface with a nozzle has a hard surface, and the skin feel is poor due to the unevenness of the surface. In addition, since only the surface layer was hard, it was easily peeled off, and the surface layer was displaced by friction, giving a sense of discomfort during use.

[0005] Absorbent cotton products whose front and back surfaces are wrapped with a nonwoven fabric material have poor water absorbency and moisture retention as compared with those made of only a cotton material, and their ends become hard due to heat sealing when cutting.
Because the nonwoven fabric is rough, it is easy to damage the skin,
There was a sense of incompatibility compared to a single material.

The present invention has been conceived in order to eliminate the above-mentioned drawbacks, and is made of a single material of cotton, in which fibers are entangled as a whole and have a binding force, and the surface is smooth and soft. It is an object of the present invention to provide a method for producing a highly entangled cotton wool material which has a good feel to the skin, does not become hard, is not fluffy or peels off in layers, and is excellent in water absorbency and moisture retention.

[0007]

According to the method for producing a highly entangled absorbent cotton material of the present invention, the absorbent cotton belt superposed in a plurality of layers is wrapped in the net on a net-shaped transport conveyor, and transported and supplied. At a halfway point, water is finely sprayed with a nozzle from above the absorbent cotton belt, and at the same time, water is sucked by a suction box provided below the absorbent cotton belt at the injection position, so that water is injected in a cross-sectional direction of the entire absorbent cotton belt. Quickly pass, entangle the cotton fibers of each layer of the absorbent cotton belt, and further, at a subsequent halfway point, after squeezing the absorbent cotton belt with a plurality of compression rollers wound tightly with a non-woven fabric to smooth the surface, It is characterized by drying.

[0008]

In the method for producing a highly entangled absorbent cotton material having the above-mentioned structure, the degreasing,
The bleached or dyed cotton is trimmed and superimposed in layers, sandwiched in a cotton wool band having a thickness according to the product specifications, and if continuously supplied, it is conveyed by a conveyor, on the production line, Finally, the product is dried while repeating the manufacturing process of the parts such as the water jet and the squeezing roller.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the method for producing highly entangled absorbent cotton material of the present invention will be described below with reference to the drawings.

A product is manufactured by sequentially performing the following steps (A) to (F). This method is called a first method.

(A) A multi-layered cotton wool band that has been degreased, bleached, or dyed thereafter is sandwiched between net-shaped conveyors. (B) Apply a slight pressure to the inside of the water curtain box to flow the water stream over the surface of the absorbent cotton belt. (C) Apply a negative pressure in the suction box for water curtain to suck excess water from the absorbent cotton belt. (D) Water adjusted to an appropriate pressure is supplied and jetted into the water jet nozzle box, and at the same time, suction is performed by applying a negative pressure to the water jet suction box. (E) Press the absorbent cotton belt with a pressing roller. (F) Dry the cotton wool belt in a drying room.

After the step (D), as (D-1), a step of inverting the net of the conveyor is inserted, and the step (D) is performed again, and the process proceeds to (E). There is a case where the confounding is made from behind and the bonding strength is further increased, and the manner of doing so is referred to as a second method. In the second method, (A) to (C) and (E) and (F) are the same as in the first method.

FIG. 1 is a simplified explanatory view of a production line for performing the second method. The absorbent cotton belt is continuously transported by a single net-shaped transport conveyor 1 throughout the entirety.

First, the above step (A) is performed in the material mounting port 2.

Next, in the water curtain box 3,
Step (B) is performed. This makes it possible to make the surface of the absorbent cotton belt smooth and at the same time to wash off oil and dirt by the water flow.

Next, the above step (C) is performed in the water curtain suction box 4. As a result, the absorbent cotton belt can be brought into close contact with the conveyor and slack, twist, and wrinkles can be removed.

Next, the water jet nozzle box 5 and the water jet suction box 6
They are arranged vertically above and below the conveyor. In the water jet nozzle box 5, a plate provided with injection ports having a diameter of 0.1 mm to 0.2 mm arranged at a pitch of about 1 mm is set at a lower portion. The pressure of the water supplied into the water jet nozzle box 5 is adjusted in several stages. The negative pressure of the water jet suction box 6 can also be adjusted in several stages. Water jet nozzle box 5
In the suction box 6 for water jet, the above-mentioned step (D) is performed, whereby water quickly passes vertically across the absorbent cotton band in the cross-sectional direction, and the cotton fibers are entangled not only on the surface but also inside.

Next, an inversion section 7 is arranged, and the (D-
Step 1) is performed.

Next, the step (D) is performed again.

Subsequently, a pressing roller 8 in which a non-woven fabric is wound tightly in multiple layers is arranged, and the step (E) is performed. Thereby, dehydration and smooth finishing of the surface can be performed.

Finally, the step (F) is performed in the dryer 9. At this time, hot air is circulated, and the absorbent cotton belt is passed through the drying chamber 9 kept at low humidity and high temperature.

A product can be produced by the above production line. In some cases, steps (B) and (C) can be omitted.

A plurality of pairs of the water jet nozzle box 5 and the water jet suction box 6 can be arranged continuously as required.

[0024]

Since the present invention is configured as described above, it has the following effects.

Since water is quickly passed in the cross-sectional direction of the whole cotton swab and the cotton fibers of each layer are entangled with each other, a cotton product for cosmetics or the like made of a single material having a binding force which is well entangled throughout can be used. Can be manufactured. Therefore, it is possible to manufacture an integrated product which is excellent in water absorbing and moisturizing properties and does not peel off in layers or harden somewhere.

In order to quickly pass water in the cross-sectional direction of the whole cotton swab, when the net-shaped conveyor is turned over to perform the work from both the front side and the back side of the cotton swab, When the operation is performed from the back side, the pressure of the water supplied to the water jet nozzle box 5 and the water jet suction box 6
Can be independently changed. Therefore, it is possible to give each of the front and back surfaces a degree of entanglement according to the intended use.

Therefore, it is possible to produce a product having two uses with the same absorbent cotton band. In other words, it is possible to provide a cotton wool product having two functions capable of performing operations such as removing makeup on the front side and applying a lotion on the back side.

Further, by providing a facility in which the arrangement interval of the mesh of the net of the conveyor and the arrangement of the injection ports of the water jet nozzle box 5 is changed, the pitch of the entanglement of the cotton fibers of the absorbent cotton belt can be changed.

[0029] With this arrangement, if the mesh of the net of the conveyor is enlarged, the entangled portions of the cotton fibers of the absorbent cotton band are strongly entangled in a hole shape, so that the absorbent cotton band can be treated in a gauze shape. it can.

Further, since the surface is smoothed by pressing with a pressing roller, it is possible to produce a cotton product having a smooth and soft surface and a good touch to the skin.
