Abstract
Abstract This invention concerns a process of producing a synthetic suede covered composite article which comprises the steps of fabricating a flexible laminate comprising a layer of nonexpandable vinyl polymer and a layer of expanded vinyl polymer, forming the flexible laminate against a surface wherein the nonexpandable layer is adjacent the surface, applying a backing material to the formed laminate adjacent the expanded layer to make a composite article, removing the composite article from the surface and stripping the nonexpandable layer from the expanded layer to produce a suede surface on the composite article.
