Abstract
Abstract A waterproof, breathable textile substrate and a process for producing same are disclosed and claimed herein. The substrate is preferably interstice containing and an extensible polymer film is applied onto a side thereof, intended for interior use with respect to contact with water, etc., without striking through to an opposite side thereof. A durable, water repellant composition may also be applied to the complete substrate if desired. The process for producing the waterproof, breathable substrate according to the present invention involves the presentation of a smooth substrate to an applicator unit and the application thereat of a polymeric film forming composition onto one side of the substrate only without any of the composition striking through the substrate to the opposite side thereof. Subsequent to application of the polymeric composition, the substrate is handled on the uncoated side only prior to formation of the film. The film is formed during drying of the substrate, preferably in a completely relaxed condition both in the longitudinal and transverse directions.
