ABSTRACT:
A moisture-permeable waterproof fabric comprising a textile fabric and, provided on at least one surface of said textile fabric, a resin film comprising a polyurethane resin produced by reacting an isocyanate with a polyol and a chain extender and having a glass transition temperature in the range of from -20.degree. to 20.degree. C. and an ethylene oxide unit content of at least 7.0 mol/kg. The moisture-permeable waterproof fabric is produced by coating at least one surface of a textile fabric with a solution of a resin in a polar organic solvent, the resin comprising a polyurethane resin, and subjecting the coating to wet solidification in a coagulation bath to form a film, or coating a release paper with a solution of a resin in a polar organic solvent, the resin comprising a polyurethane resin, to form a resin film and adhering the resin film on at least one surface of a textile fabric.
