Abstract

Abstract NOVEL URETHANE COATED FABRICS OF ENHANCES RESISTANCE TO SCUFFING AND ABRASION ARE PREPARED BY APPLYING TO A URETHANE-COATED FABRIC A TOP COATING CONSISTING OF A FLEXBLE HEAT-CURED SILICONE POLYMER. THE SEQUENCE OF BONDING THE COATING TO THE FABRIC IS NOT CRITICAL. AN ADHESIVE MAY BE APPLIED DIRECTLY TO THE FABRIC AND THE URETHANE COATING HEATING WITH PRELIMINARY APPLIED THERETO AND CURED BY HEATING WITH PRELIMINARY USE OF RELEASE PAPER FOR THE COATING. OR, THE URETHANE-COATING COMPOSITION MAY BE APPLIED DIRECTLY ON THE FABRIC WITHOUT PRIOR USE OF ADHESIVE OR RELEASE PAPER. HEAT-CURABLE SILICONE RESIN POLYMERS ARE KNOWN ARTICLES OF COMMERCE AND ARE USED IN THE FORM OF AQUEOUS EMULSIONS OR SOLUTIONS. THEY TYPICALLY INCLUDE SOLUTIONS OF ORGANOSILIOXANES, AND SILIXANE CONDENSATION CATALYSTS. SUITABLE URETHANE COATING COMPOSITIONS ARE KNOWN IN THE ART AND ARE PREFERABLY ORGANIC SOLVENT SOLUTIONS OF FULLY REACTED POLYURETHANE UREA RESINS. THE COATING COMPOSITIONS MAY BE PIGMENTED WITH A VARIETY OF INORGANIC OR ORGANIC PIGMENTS SUCH AS TITANIUM DIOXIDE, PHTHALOCYANINE GREEN, PHTHALOCYANINE BLUE, CARBON BLACK, BONE BLACK, CHROME YELLOW, CADMIUM RED AND TOLUIDINE RED. FABRICS SUITABLE FOR COATING INCLUDE LINEN NYLON COTTON, RAYON, SILK, WOOL, POLYESTER, POLYACRYLONITRILE, MODACRYLIC, OR MIXTURES THEREOF. THE NOVEL URETHANE COATED FABRICS ARE PARTICULARLY USEFUL FOR AUTOMOTIVE AND FURNITURE UPHOLSTERY.
