ARTIFICIAL LEATHER AND METHOD OF PRODUCING THE SAME

摘要

A method of producing artificial leathers which comprises coating a fibrous base material with a polymeric solution containing, as the principal ingredient, a polyurethane-urea elastomer and then treating the coated fibrous base material with a nonsolvent for the polymer to coagulate the polymer. Certain critical methods for producing the polyurethane-urea elastomer, broadly described as either a "prepolymer" process or a "one-shot" process are described in the specification.
