Claim 1
Independent Claim
82 words
A COMPOSITE MATERIAL COMPRISING A THERMOPLASTIC POLYMER OF VINYL CHLORIDE ADHERING TO SYNTHETIC-RESIN COATED, HEAT-STABLE, FIBRE-FORMING MATERIAL, SAID MATERIAL BEING COMPOSED OF A LINEAR POLYMER CONTAINING RECURRING UNITS OF CARBON. HYDROGEN, AND AN ELEMENT MORE ELECTRONEGATIVE THAN CARBON, SAID RESIN BEING A WATERINSOLUBLE, ALCOHOL-SOLUBLE CONDENSATION PRODUCT OF FORMALDEHYDE WITH RESORCINOL, IN MOLAR PROPORTIONS BETWEEN 1:2 AND 1.1:1, AND BEING THE SOLE ADHESIVE BETWEEN THE VINYL POLYMER AND THE TEXTILE MATERIAL, AND THE COMPOSITE MATERIAL BEING FREE FROM ANY SOURCE OF ADDITIONAL FORMALDEHYDE.
Claim 2
Dependent Claim
119 words
PROCESS FOR MAKING A COMPOSITE MATERIAL, WHEREIN A DISPERSION OF THERMOPLASTIC POLYMER OF VINYL CHLORIDE IN A PLASTICISER THEREFOR IS APPLIED OVER THE SURFACE OF A WOVEN FABRIC OF WHICH AT LEAST 50% BY WEIGHT OF THE YARN IS COMPOSED OF HIGH TENACITY REGENERATED CELLULOSE CONTINUOUS FILAMENTS, THE SAID FABRIC BEING COATED WITH A SYNTHETIC RESIN WHICH IS A WATER INSOLUBLE, ALCOHOL SOLUBLE CONDENSATION PRODUCT OF AN ALDEHYDE AND A PHENOL IN MOLAR PROPORTIONS BETWEEN 1:2 AND 1.1:1, AND THE RESIN COATED FABRIC IS HEATED TO FORM SAID DISPERSION INTO A GEL, THE SAID RESIN BEING THE SOLE ADHESIVE BETWEEN THE VINYL POLYMER AND THE TEXTILE MATERIAL AND THE COMPOSITE MATERIAL BEING FREE FROM ANY ADDITIONAL SOURCE OF FORMALDEHYDE.
