ABSTRACT:
A process for the production of a fabric/elastomer composite is provided. The inventive process involves the impregnation through a printing procedure of an inventive elastomer composition comprising (i) a water-borne polyurethane latex, (ii) an acid-generating chemical, (iii) a cloud point surfactant, (iv) a thickener, and (v) optionally, a cross-linking agent, within a textile fabric. Subsequently, the impregnated fabric is then heated, preferably with steam, in order to generate an acid, which, in turn, permits the surfactant to gel and uniformly coagulate the latex over the fabric surface. The fabric is preferably a circular knit comprised of polyester and/or lycra fibers. The composite may be utilized within any fabric application requiring a support function, particularly as joint braces, sports brassieres, support apparel, and the like. The inventive elastomer composition is also provided.
