  • 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.

  • Patent number: 4840817
    Abstract: A fabrous material is impregnated with a treating agent comprising (1) a tetrakishydroxymethyl phosphonium compound or an ammonium condensate of a tetrakishydroxymethyl phosphonium compound, (2) methylolmelamine and (3) urea, thiourea or a guamidine salt, and the fabric is heated with high-pressure steam or subjected to a microwave heat treatment in the pressure of water vapor. A high and durable flame retardancy can be imparted to the fibrous material by this treatment. Especially good results are obtained when a fibrous material composed of a mixture of a polyester fiber and a cellulose fiber is treated according to this method.
