PURPOSE: To obtain a soft and excellent heat insulating, moisture-permeable and waterproof fabric by forming a resin composition containing specific metallic powder added to a one-pack type moisture permeable polyurethane resin into a thin film, applying a specified resin composition onto the resultant thin film and laminating a fabric thereto. n CONSTITUTION: For example, a resin composition containing metallic fine powder having ≤0.3 emissivity (preferred example; aluminum) added to a one-pack type polyurethane resin is applied to a polypropylene-coated paper with a knife coater, etc., to form a skin layer of the above-mentioned resin. The resultant skin layer is then coated with a resin composition consisting of a two-pack type polyether polyol-modified polyurethane resin, melamine derivative, organic polyisocyanate (e.g., diphenylmethane-4,4'-diisocyanate) and a crosslinking catalyst (e.g., consisting of a melamine crosslinking and urethane crosslinking catalysts). A fabric consisting of a polyester-based fiber is subsequently laminated thereto through the afore-mentioned composition and thermocompression bonded to afford the objective heat insulating, moisture-permeable and waterproof fabric having excellent mechanical characteristics and suitable for sportswear, etc. n COPYRIGHT: (C)1990,JPO&Japio |
