The process comprises continuously feeding at least three separate films, sheets or webs of the appropriate non-fibrous feed materials into the nip formed by two rotating, heated cylinders wherein the feed materials are contacted under pressure with two heated flexible molding bands provided with a multiplicity of molding cavities whereby outwardly extending fibrous polyurethane surfaces are formed and wherein the separate layers are welded together. The novel synthetic suede product obtained by this process is also disclosed and claimed.
