Description

[Detailed description of the invention] (Industrial application field) This invention relates to a sweat-absorbing multilayer fabric useful for shoe parts such as shoe laces, linings, and insoles, and clothing core materials and lining materials. It is.

(Prior Art) Conventionally, breathable laminated fabrics for shoe coverings, which are laminated with a water-absorbing open-cell foam such as rubber latex foam interposed between hydrophobic fiber fabrics such as polyamide, are generally well known. be.

However, when shoes covered with these laminated fabrics are worn for a long time, the water absorption rate of the water-absorbing open-cell foam reaches a saturated state, reducing breathability and sweat absorption, and the inside of the shoe becomes The problem was that it was sticky due to sweat.

(Problems to be solved by the invention) This invention aims to provide an item that can continuously exhibit breathability and sweat absorption even when worn for a long time.

(Means for solving the problem) This invention will be explained below with reference to the actual drawings.
The gist of this invention is to create a sweat-absorbent multi-layered cloth characterized by layering a hydrophobic fiber cloth 1, a water-absorbing open-cell foam 2, and a hydrophobic open-cell foam 3. It is something to do.

In this invention, the hydrophobic fiber cloth 1 is composed of a woven fabric, knitted fabric, or nonwoven fabric made of synthetic fibers such as polyamide, polypropylene, and polyurethane.

In this invention, the water-absorbing open-cell foam 2 is an open-cell foam made of rubber latex or synthetic resin emulsion, other rubbers, vinyl chloride, EVA, polyurethane, or other rubber or synthetic resin open-cell foam. The body contains crushed pulp, cellulose fibers such as rayon, hydrophilic fibers such as cotton and vinylon, or saponified starch polyacrylonitrile graft copolymers, starch polyacrylic acid graft copolymers, crosslinked cellulose, crosslinked polyacrylates, It is composed of super water absorbent resins such as saponified vinyl acetate acrylic acid copolymer, starch grafted polyvinyl acetate, crosslinked modified polyvinyl alcohol, and crosslinked polyethylene oxide.

In this invention, the hydrophobic open-cell foam 3 is an open-cell foam made of ordinary rubber to which no hydrophilic fiber or superabsorbent resin is added, rubber such as vinyl chloride, EVA, polyurethane, or synthetic resin. Composed of foam.

If necessary, the strength of the hydrophobic open-cell foam 3 can be increased by layering reinforcing cloth 4 on the hydrophobic open-cell foam 3.

In this invention, the hydrophobic fiber cloth 1, the water-absorbing open-cell foam 2, and the hydrophobic open-cell foam 3 are sewn, for example, by quilting stitching, or by applying adhesive in dots or lines on the joint surfaces. By coating, the water-absorbing open-cell foam 2 can be bonded in dots or lines, or when the water-absorbing open-cell foam 2 is molded, the hydrophobic fiber cloth 1 and the hydrophobic open-cell foam can be attached to the water-absorbing open-cell foam 2. The foam body 3 is layered by bonding the foam body 3 together in a layered manner.

(Effects of the invention) Since this invention is constructed as described above, when the hydrophobic fiber cloth 1 is worn facing the body, the sweat generated by the body is absorbed by the hydrophobic fiber cloth 1. Sweat is absorbed by the water-absorbent foam 2 through the hydrophobic fiber cloth 1 without any sweat being absorbed, and the sweat absorbed by the foam 2 is further absorbed by a large number of hydrophobic foams 3 layered on the foam 2. It is released onto the surface 32 or side surface 33 of the foam 3 by capillary action caused by the open cells 31, 31, .

Therefore, the absorption rate of the water-absorbent foam 2 does not reach a saturated state when worn for a long period of time, unlike conventional methods, and the sweat-absorbent multilayer fabric of this invention maintains excellent breathability and sweat absorption. can be demonstrated.
