Abstract: This invention provides a waterproof and moisture-permeable fabric which prevents to lower in a water pressure resistance, repetitively washed. The waterproof and moisture-permeable fabric consists of a body of a fabric and a microporous film of mainly polyurethane which is laid on the body. The microporous film contains 1 to 9 mass % of fluorinated water repellent agent, 0.1 to 2 mass % of oil-soluble fluorinated surfactant and if necessary 3 to 45 mass % of fine silica powders. The waterproof and moisture-permeable fabric is obtained by the following method. After coating a resin compound on the surface of the body, the resin compound is dipped in a coagulating bath to form the microporous film. The resin compound dissolves or disperses mainly polyurethane, 1 to 9 mass % of fluorinated water repellent agent, 0.1 to 2 mass % of oil-soluble fluorinated surfactant and if necessary 3 to 45 mass % of fine silica powders in N,N-dimethylformamide.

Abstract: This invention provides a fabric having a foamed layer. The fabric is obtained by the foaming method which prevents to expand heat expansible micro capsules in a cross-linked resin. A foamed layer is laminated on the fabric material. The foamed layer is comprising of heat expanded micro capsules, a synthetic resin holding the capsules on the fabric material, silica fine powders which are hydrophilic and fine porous. The fabric is obtained by the following method. A synthetic resin solution comprising of heat expansible micro capsules and the silica fine powders is prepared. The solution is applied on the fabric material at all surface or pattered surface. The synthetic resin layer is formed after drying. After that, the heat expansible micro capsules are expanded by heating.

Abstract: A synthetic fiber capable of absorbing and disabsorbing moisture comprising a component capable of absorbing and disabsorbing moisture and a fiber-forming polymer. The fiber of the present invention has a moisture absorption of 1.5% or more when it is allowed to reach a moisture equilibrium under the circumstance of 25° C.×60%RH and then is allowed to stand for 30 min. under the circumstance of 34° C.×90%RH, and has a moisture disabsorption of 2% or more when it is allowed to reach a moisture equilibrium under the circumstance of 34° C.×90%RH and then is allowed to stand for 30 min. under the circumstance of 25° C.×60%RH. The fiber also has a value of −1 to 5 in terms of b value in the CIE-LAB color system when it is allowed to stand for 30 days.
