Description of the Related Art Conventionally, as a method for producing a moisture-permeable waterproof cloth that requires high moisture permeability such as ski wear and outdoor wear, a microporous film of polyurethane resin is formed on a fiber substrate by a wet method or a dry method. The method of forming is done. For example, as a general method for producing a moisture-permeable waterproof cloth by a wet method, a polyurethane resin on a fiber substrate,
A method is known in which a microporous film is obtained by applying a resin solution containing a polyisocyanate crosslinking agent and a polar organic solvent, coagulating, washing with water, and drying. On the other hand, the dry method comprises a polyurethane resin, a polyisocyanate crosslinking agent and two or more kinds of diluents having different boiling points (generally, a low boiling organic solvent having high volatility and water) on a fiber substrate. A method is known in which a microporous film is obtained by applying multi-stage drying from low temperature drying to high temperature drying after applying a resin solution. More recently, as a dry process, polyurethane resins have water-soluble substances (eg salt, sugar,
Glauber's salt, sodium glutamate, gelatin, starch, etc.)
After applying the composition containing the added to the fiber base material, it is dried to form a film, and then immersed in water to dissolve and remove the water-soluble substance in the film to give a unique microporous film. A way to get is found. The moisture-permeable waterproof cloth as described above has a large dependency of moisture permeability on the outside air temperature, and the outside air temperature is in a range of 20 to 4 within a high range.
It has high moisture permeability at 0 ° C, but the temperature in winter is 0
The moisture permeability is remarkably reduced in an environment of -20 ° C. In other words, considering conventional sportswear, when the outside air temperature is high, even if the amount of exercise is intense and the amount of sweat increases sharply, stuffiness during wear hardly occurs due to high moisture permeability, but in winter sports such as skiing When using a damp waterproof fabric, the outside air is at a low temperature and the moisture permeability of the microporous film is significantly reduced, so there is a drawback that stuffiness and dew condensation will occur when the body is vigorously moved and the amount of sweating increases, and when worn The discomfort of was unavoidable.

くなるので好ましくない。As the keratin-modified powder used in the present invention, a powder obtained by partially cleaving the disulfide bond of cystine is used. This is the most preferable because it has excellent hygroscopicity and water retention and has water insolubility. Those in which the disulfide bond is not cleaved are water-insoluble, but cannot exhibit sufficient performance because of their low hygroscopicity and moisture retention. On the other hand, those in which the disulfide bond is completely cleaved have very good hygroscopicity and moisture retention,
It is not suitable because it is easily soluble in water and most of it elutes during wet processing. In addition, the shape has a particle size of 1 to 50 μm.
Fine particles of m are preferable, and if the particle size exceeds 50 μm, spots and streaks may occur during coating. The amount of the keratin-modified powder used is 0.5 to 30% by weight, preferably 1 to 10% by weight. If the amount used is less than 0.5% by weight, sufficient performance cannot be obtained, and conversely, if it exceeds 30% by weight, the physical properties of the film deteriorate, which is not preferable.

硬化するので好ましくない。Examples of the polyisocyanate crosslinking agent used in the present invention include compounds having two or more isocyanate groups such as diisocyanate crosslinking agent and triisocyanate crosslinking agent. For example, 2,4- (2,6-) triisocyanate is used. Diisocyanate, hexamethylene diisocyanate,
1,4-naphthalene diisocyanate, diphenylmethane-4,4'-diisocyanate, isophorone diisocyanate and other diisocyanate cross-linking agents and triisocyanate cross-linking agents that are adducts of these diisocyanate cross-linking agents with trimethylolpropane, glycerin, etc. You can choose. The amount of these polyisocyanate crosslinking agents used is 0.3 to 2% by weight, preferably 0.6 to 1.3% by weight. If the amount used is less than 0.3% by weight, the adhesive force of the resin to the fabric will be poor, and conversely, if it exceeds 2% by weight, the texture will be hardened, which is not preferable.

湿性防水布帛は、特にスキーウエア、アウトドアウエア
等のスポーツ衣料に適した素材である。As described above, the moisture-permeable waterproof cloth according to the present invention has an extremely small change in the amount of moisture permeation due to the change in the outside air temperature due to the keratin-modified powder in the film, and is very excellent in the prevention of dew condensation. There is. Therefore, it goes without saying that if a garment is made using this moisture-permeable waterproof cloth, the sweat releasing ability is good when the amount of sweating increases in the season (spring to autumn) when the outside air temperature is high to some extent. That is, sweat is satisfactorily released to the outside even in the winter when the outside air temperature is relatively low. Therefore, the present invention keeps the excellent waterproofness and water resistance of the conventional breathable waterproof cloth, and at the same time, regardless of the temperature of the environmental conditions, even if the amount of perspiration increases, the environment is always comfortable for the body. It is provided. The moisture-permeable waterproof fabric of the present invention is a material particularly suitable for sports clothing such as ski wear and outdoor wear.
