  • Moisture-permeable, waterproof fabric and its production process
    Patent number: 5753568
    Abstract: A moisture-permeable, waterproof fabric comprising a textile fabric and a resin coating containing a fluorine-containing polyurethane resin and polyurethane resin having a low degree of polymerization on at least one side of said textile fabric. This moisture-permeable, waterproof fabric is obtained by a process comprising coating a resin solution, containing a fluorine-containing polyurethane resin and a polyurethane resin having a low degree of polymerization, on at least one side of a textile fabric, followed by coagulating the resin, removing the solvent, drying the fabric and applying a water repellent.
    Type: Grant
    Filed: December 2, 1996

  • Moisture-permeable waterproof fabric and process for producing the same
    Patent number: 5692936
    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.
