Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothing material having excellent heat retention and comfort.

[0002]

2. Description of the Related Art Conventionally, it has been known that some ceramics radiate far infrared rays, and attempts have been made to use these to give a thermal effect to a human body. For example, JP-A-63-152413 discloses that a fiber having a far-infrared radiation effect is obtained by incorporating ceramics into a polymer and spinning the resulting fiber product. These far-infrared emitting fibers are useful, but in practice, it is not easy to mix ceramics in a polymer and carry out spinning because of many problems. Therefore, it is known to coat a resin containing ceramics after forming a fiber structure such as a woven or knitted fabric.

[0003]

However, the heat retention and comfort of the conventional fiber structure having a synthetic resin on the surface have not been sufficiently satisfactory. That is, these fiber structures do not feel sufficient heat retention when worn, and cause sweating or rash when sweating due to intense exercise, and are not suitable for long-term wearing. It was

An object of the present invention is to eliminate the drawbacks of the conventional fiber structure having a synthetic resin film containing ceramics and to provide a clothing material having excellent heat retention and comfort.

[0005]

[Means for Solving the Problems] The above-mentioned object is characterized in that the outer material and the inner material are bonded together by a water-soluble adhesive material, and the bonding surface of the outer material is covered with a resin film containing ceramic particles. It is achieved by the cloth for clothing.

The present invention will be described in detail below.

The outer material and lining referred to in the present invention are woven fabrics and knitted fabrics using synthetic fibers such as polyamide, polyester, polyacryl and the like and / or natural fibers such as cotton, wool and silk, which are usually used for clothing and the like. It is a cloth such as a non-woven fabric and is not particularly limited.

The ceramics in the present invention comprises titanium nitride, aluminum oxide, silicon carbide, zirconium carbide, zirconium oxide, etc., or a mixture thereof,
The solid fine particles have a particle diameter of about 0.1 to 20 μm.

It is preferable that the ceramic particles are uniformly present in the resin, and it is preferable that the ceramic particles adhere to the surface material in an amount of about 3 to 6 g / m ² . This has a ceramic particle adhesion of 3
If it is less than g / m ² , a sufficient far-infrared radiation effect may not be obtained, and if it exceeds 6 g / m ² , the effect is saturated.
This is because the durability of the resin film also decreases.

The silicone resin preferably used as the resin in the present invention has a coating effect and plays a role of an adhesive between the ceramic particles and the surface material, and is particularly excellent in dispersibility in water. A silicon-based aqueous emulsion type that can be easily diluted, for example, an organopolysiloxane as a main component, which is emulsified with an emulsifier, is preferable. This has a rubber-like film that is cured by removing water and has the characteristics of silicone rubber, and exhibits a durable adhesive effect.

The organopolysiloxane emulsion is more preferably a low temperature reaction type organopolysiloxane prepolymer emulsion. The low-temperature-reactive organopolysiloxane prepolymer emulsion referred to herein is, for example, 100 parts by weight of organopolysiloxane having at least two hydroxyl groups bonded to silicon atoms in one molecule and its derivative, and aminofunctional silane or its derivative. 0.1-10 parts by weight of a reaction product of a hydrolyzate and an acid anhydride and colloidal silica 1
1 to 60 parts by weight of a uniform dispersion liquid of about 50 parts by weight with respect to the organopolysiloxane and 0.01 parts of a curing catalyst.
An aqueous emulsion of silicon comprising 10 to 10 parts by weight, 0.3 to 20 parts by weight of an anionic emulsifier, and 25 to 600 parts by weight of water is included.

As the resin applicable to the present invention, a low temperature reactive blocked isocyanate prepolymer emulsion may be used together with a fatty acid metal salt. This low-temperature-reactive blocked isocyanate prepolymer reacts with isocyanate groups to form a temporarily stable compound such as sodium bisulfite, acetylacetone, ethyl acetoacetate, and diethyl malonate, which is then thermally dissociated by heat treatment. And a prepolymer obtained by polymerizing an acrylic or methacrylic compound and a modified acrylic or methacrylic compound such as silicon-modified or fluorine-modified is a compound containing at least one blocked isocyanate group that regenerates an isocyanate group in a molecule. Can be mentioned.

The metal salt of fatty acid is a catalyst for promoting the dissociation of blocked isocyanate, and examples thereof include zinc octylate, zirconium octylate, zinc laurate, and zinc stearate.

Further, as the resin, it is also possible to use an emulsion of an acrylic or methacrylic compound obtained by emulsion polymerization of a monomer containing one or more vinyl groups. Such emulsions include, for example, acrylic acid, methacrylic acid, methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, butyl acrylate, butyl methacrylate,
Acrylonitrile, acrylamide, N-methylol acrylamide, 2-hydroxyethyl acrylate, 2
-Emulsion polymer emulsion such as hydroxybutyl acrylate.

Furthermore, a polyalkylene emulsion,
An emulsion of a polyester resin composed of a polyhydric alcohol and a polybasic acid or a polyurethane emulsion composed of a diisocyanate and a polyol can also be used as the binder.

Examples of the polyalkylene include polyethylene and polypropylene, and examples of the polyhydric alcohol include ethylene glycol, 1,4-butanediol,
1,6-hexanediol, diethylene glycol, trimethylolpropane, and polybasic acids include phthalic acid, adipic acid, maleic acid, trimetic acid, and terephthalic acid. Further, as the diisocyanate, hexamethylene diisocyanate, xylene diisocyanate, tolylene diisocyanate, 4,4'-diphenylmethane diisocyanate, 1,5-naphthalene diisocyanate, etc., and as the polyol, polyethylene adipate, polypropylene adipate, polybutylene adipate, polyethylene. Examples thereof include phthalate, polyethylene glycol, polypropylene glycol, polyethylene propylene glycol, etc., and an emulsion of a polyurethane resin made of these forms a water-insoluble resin by a drying treatment.

Such a resin is used in an amount of 1 to 10 g / m ^{2 with} respect to the surface material.
It is preferably adhered to some extent. This has a resin adhesion of 1
This is because if it is less than g / m ² , a sufficient adhesive effect may not be obtained, and if it exceeds 10 g / m ² , the feel becomes hard.

Examples of the water-soluble paste material applicable to the present invention include starches (starch, soluble starch, water-soluble starch derivatives, etc.), water-soluble cellulose derivatives (carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, etc.), sodium alginate, Arabic. Gum, gums (locust bean gum, guar gum, etc.),
Examples include water-soluble proteins (gelatin, glue, etc.), water-soluble synthetic polymer compounds (sodium polyacrylate, polyvinyl alcohol, polyethylene oxide, polyvinylpyrrolidone, polyacrylamide, polyethyleneimine, quaternized water-soluble cationic polymers, etc.) ..

It is preferable that 0.01 to 5 g / m ^{2 of} such a water-soluble paste material is adhered in a dot shape having a diameter of 1 to 3 mm between the surface material and the backing material. This is because, outside this range, the surface and lining are not easily separated by washing with water after sewing.

Next, a production example of the clothing material according to the present invention will be described.

First, formation of a film containing ceramic particles on the bonding surface of the outer material is achieved by using a treatment liquid containing ceramic fine particles, a resin and, if necessary, a thickener. The application of such treatment liquid to the outer material is preferably performed by a coating method, and if necessary, a foaming agent may be added to use a foam processing method. Examples of such a foaming agent include isobutane-based foaming agents called saran microspheres.

Further, the heat treatment is followed by drying at 100 to 130 ° C. and then heat treatment at 150 ° C. for about 3 minutes, whereby the resin is fixed to the fiber structure.

Next, a production method for obtaining a cloth by laminating a coated surface material and a lining material prepared separately will be described. A water-soluble paste material is thickened to 100 to 30000 cps,
A gravure roll, a rotary screen, a screen printing device or the like is used to print on the resin film forming surface and / or the lining of the outer material, and the nip roll presses the outer material and the inner material together, and the material is dried.

[0024]

[Function] The far-infrared ray effect is obtained because the outer material is covered with a resin film containing ceramic particles, and since the outer material and the lining are bonded together with a water-soluble glue, it is washed with water after the cutting and sewing process. In the process, the air layer is formed by the natural separation of the outer material and the lining,
It becomes excellent in heat retention. In addition, since no resin film is formed on the lining, it absorbs sweat and water when sweating due to intense exercise, and also has comfort.
