Abstract
A process for the production of a fabric/elastomer composite is provided. The inventive process involves the impregnation of an inventive elastomer composition comprising (i) a water-borne polyurethane latex, (ii) an acid-generating chemical, and (iii) a cloud point surfactant, within a textile fabric. Subsequently, the impregnated fabric is then heated, preferably with steam, in order to generate an acid and gel the surfactant which then uniformly coagulates the latex over the fabric surface. The fabric is preferably comprised of polyester fibers. The composite may be utilized as upholstery in furniture or in automobiles, apparel, drapery, and the like. The inventive elastomer composition is also provided.
