* Explanation of symbols on the main parts of the drawings

A: nonwoven fabric containing superabsorbent fibers

B: breathable waterproof sheet

C: quick drying fabric

The present invention relates to a cold feeling sheet excellent in comfort, and more particularly, the present invention relates to the cooling effect of water itself by absorbing water in an absorbent material, and the hot summer outdoor activity by taking heat away from the skin while the water is rapidly diverging and vaporizing. The present invention relates to a cold feeling sheet capable of maintaining a cooling performance relatively comfortably and effectively for a long time in a hot workplace.

Japanese Patent Laid-Open No. Hei 9-253119 invented a cooling product that can be used for neck bands, wrist bands, etc. by inserting a super absorbent polymer into a tubular structure made of fabric. This patent has been proposed to improve the disadvantage that the superabsorbent resin inside the one-piece fabric sewing material absorbs water, and the superabsorbent resin swells and becomes almost circular in cross section, thereby reducing the area of contact with the skin. Sewing was made in the form of connecting several tubes, but even in this case, the tube form becomes circular as the superabsorbent polymer expands, so there is a problem that the increase of the skin contact area is inferior to the plane.

In Japanese Patent Application Laid-Open No. 10-339536, a non-woven fabric applied with superabsorbent fibers instead of superabsorbent resin was put inside the fabric to give a cooling effect.In this case, however, the skin contact area is effective, but the fabric that contacts the skin becomes wet with water. The damp feeling is transmitted to the skin as it is, there is a problem that the user feels uncomfortable.

Korean Patent Laid-Open Publication No. 2001-333928 has been made of a structure in which a superabsorbent polymer is wrapped with a superabsorbent fiber woven or nonwoven fabric, and then the outside thereof is wrapped with a synthetic fiber bag. The problem of directly contacting is not improving.

The object of the present invention is to solve the conventional problems as described above, while releasing water while maintaining moisture for a long time when absorbing water to exert a cooling effect for a long time, the moist part does not directly contact the skin, sweat emitted from the skin The purpose is to provide a cold feeling sheet having a three-layer structure which effectively discharges.

The cold-sensing sheet of the present invention for achieving the above object is a non-woven fabric (A) containing a superabsorbent fiber, a moisture-permeable waterproof sheet (B) bonded to one side of the nonwoven fabric and the sweat-absorbent quick-drying bonded to the other side of the nonwoven fabric Characterized in that composed of the fabric (C).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, the present invention is a non-woven fabric (A) comprising a superabsorbent fiber as shown in Figure 1, a moisture-permeable waterproof sheet (B) is bonded to one side of the nonwoven fabric and the sweat-absorbent quick-drying fabric is bonded to the other side of the nonwoven fabric It has a three-layer structure comprised by (C).

1 is a schematic cross-sectional view of the present invention.

The nonwoven fabric A including the superabsorbent fibers may be composed of superabsorbent fibers and ordinary synthetic fibers, or may be composed of superabsorbent fibers alone.

When the nonwoven fabric (A) comprising the superabsorbent fibers is composed of superabsorbent fibers and ordinary synthetic fibers, the superabsorbent fibers content is 20 to 50% by weight relative to the total weight of the nonwoven fabric (A) to sufficiently absorb and retain moisture. It is desirable to.

It is preferable that the weight of the nonwoven fabric (A) containing a superabsorbent fiber is 50-150 g / m <2>.

If the weight of the nonwoven fabric is less than 50g / ㎡ can reduce the cooling effect, if it exceeds 150g / ㎡ the weight is heavy and may be a bad fit.

As the superabsorbent fibers, fibers made of Acrylic acid / methyl acrylate copolymers such as Oasis (trade name) produced by Technical Absorbents company, or are used Fiber made from isobutylene / maleic anhydride copolymer, such as Fibersorb (trade name) produced by Camelot Superabsorbents, or Toyobo ) Acrylic fiber such as Lanseal (trade name) of the company is used.

In the case of using the Oasis (trade name) or five-sorb (Fibersorb (trade name)) as a super absorbent fiber, a needle punched nonwoven fabric is prepared by mixing 20 to 50% of super absorbent fiber and 50 to 80% of polyester fiber. Since the two superabsorbent fibers lack shape stability when water is absorbed, the superabsorbent fibers may be mixed with polyester fibers to ensure morphological stability of the superabsorbent layer. Since Lanseal (trade name) is about 30% of the surface layer of the yarn hydrolyzed and absorbent, even if a nonwoven fabric is formed alone, the shape stability of the super absorbent layer is secured.

The moisture-permeable waterproof sheet (B) used in the present invention is a moisture-permeable moisture-proof waterproof fabric used for conventional moisture-permeable fabrics, such as a polyurethane sheet manufactured by a wet method, a polyurethane nano web sheet made by an electrospinning, and a polytetrafluoroethylene film. Sheet is possible. When bonding the moisture-permeable waterproof sheet (B) with the nonwoven fabric (A), hot melt or polyurethane-based adhesive may be used depending on the type of moisture-permeable waterproof sheet. However, when using the polyurethane sheet, the adhesive solvent may damage the polyurethane sheet. Therefore, it is preferable to adhere by hot melt method.

The sweat-absorbent quick-drying fabric (C) used in the present invention may be a fabric which is applied to a sweat-absorbing quick-drying yarn that is widely applied to general sports clothing, that is, Kolon Co., Ltd.'s Coolon (trade name) and Invista's Coolmax (trade name) yarn. . When adhering the sweat-absorbing quick-drying fabric (C) with the nonwoven fabric (B), the polyurethane-based adhesive may be adhered to the nonwoven fabric by gravure coating of a polyurethane-based adhesive on the fabric surface or a hot melt adhesive may be used.

The sweat-absorbing quick-drying fabric (C) is preferably composed of a release cross-section yarn.

Looking at an example of a method for producing a cold-feel sheet of the present invention, after mixing the super absorbent fibers and polyester fibers and needle punching them to form a nonwoven fabric (A), the moisture-permeable waterproof sheet ( B) is bonded with a hot melt or adhesive, and the moisture-absorbing quick-dry yarn (C) is bonded to the opposite side of the nonwoven fabric (A) using a hot melt or adhesive. The three-layer sheet thus formed is a non-woven fabric (A) mixed with the superabsorbent fibers when wet in water absorbs a large amount of water, and the polyester fibers mixed together to maintain the shape of the superabsorbent layer. The moisture-permeable waterproof sheet (B) bonded to the inside prevents water absorbed by the nonwoven fabric (A) from directly contacting the skin, thereby preventing skin discomfort when made into a product such as a hat, vest, hair band, or neck band. , Moisture generated from the skin, sweat is absorbed into the nonwoven fabric (A) through the moisture-permeable waterproof sheet (B). Since the water absorbed by the nonwoven fabric (A) has a low temperature of its own, if it has a cooling effect in a hot season or in a working environment, and gradually absorbs and dissipates the water of the nonwoven fabric (A) from the sweat-absorbing quick-drying fabric (C) bonded to the outside, It can give cooling effect by evaporation heat and can maintain the effect for a long time.

Hereinafter, the present invention will be described in detail through Examples and Comparative Examples. However, the scope of the present invention is not limited by the following examples.

Example  One

A needle punched nonwoven fabric having a weight of 100 g / m 2 was prepared by mixing 30% by weight of a super absorbent fiber (trade name: Oasis) staples and 70% by weight of polyethylene terephthalate fiber staples. A superabsorbent layer is formed by inserting a polyethylene-based hot melt web between the nonwoven fabric (A) containing the superabsorbent fibers thus prepared and the moisture-permeable waterproof polyurethane sheet (water-permeable waterproof sheet, B) prepared by electrospinning and thermally calendering at a temperature of 120 ° C. A nonwoven fabric and a moisture-permeable polyurethane sheet are bonded together. Next, apply a polyurethane adhesive to the gravure roll to the tricot fabric (absorbent quick-drying fabric, C) to which the sweat-absorbing quick-drying yarn (product name: Coolon) was applied, and then attach the nonwoven fabric side of the sheet of the two-layer structure manufactured above to cool the three-layer structure. The sheet was prepared. The results of evaluating various physical properties of the produced cold-feel sheet are shown in Table 2.
