Abstract: The use of clear polymeric substances, such as polyvinyl pyrrolidone and silicone resins, polyvinyl pyrrolidone/acrylates copolymers, polyvinyl methacrylate/methacrylic acid copolymers, and polyvinyl acetate resins to coat nylon and similar fabrics, thus providing a protective film that greatly increases the strength of the fiber. These polymers can be packaged in spray form, using an alcohol base as carrier. The coating can then be applied directly to the finished article by the consumer by spraying the fabric with the alcohol solution of the protective substance.
