Method of coating fibrous structure with a mixture of polyurethane pre-polymer and polyorganosiloxane
Abstract
Abstract IMPROVED FIBROUS STRUCTURES SUCH AS FIBERS, YARNS, FABRICS, MADE-UP CLOTHES AND THE LIKE, HAVING VOLUMINOUS HAND, DURABLE ELASTICITY, EXCELLENT ANTI-PILLING PROPERTY, SHRINKPROOFNESS, CRASE RESISTANCE, AND OTHER DESIRABLE CHEMICAL AND PHYSICAL PROPERTIES, ARE MANUFACTURABLE BY FINISHING THE FIBROUS STRUCTURE WITH A NON-AQUEOUS ORGANIC SOLVENT SOLUTION OF A SPECIFIED POLYURETHANE PREPOLYMER AND A SPECIFIED POLYORGANOSILOXANE TOGETHER WITH A POLYMERIZATION CATALYST. FIBERS CONSTITUTING THE STRUCTURE ARE ENTIRELY COVERED BY URETHANE/ORGANOSILOXANE COPOLYMER FILM HAVING AN ELONGATION AT BRAK OF AT LEAST 200%, A TENSILE RECOVERY AT 100% ELONGATION OF AT LEAST 70%, A TENSILE STRENGTH OF 1-50 KG./CM.2 AND A HARDNESS OF 5-60*.
