Abstract

A manufacturing process for artificially absorbing moisture-resistant artificial leather, characterized in that a matrix is first prepared by coating a ductile and flat support or base, for the preparation of what is called a "separating layer", with a base-level dough of materials having a certain adhesion to a polymer layer to be applied subsequently, such as cellulose derivatives in organic solvents, and giving the surface of said separating layer, as it remains after solidification, a die-cut or printing of negative graining, after which a mass of a polymerized material, such as softened polyvinyl chloride, is spread over said grained surface, then solidifying at 140 [deg.] c., possibly applying another layer of the same material, overlaying the still wet mass a supporting material, such as a fabric, a knitted fabric or the like, and sun idifying at a temperature of 140 to 150º c., after which the artificial leather thus originating is removed from the ductile base provided with a separating layer, extending in the concavities of the graining of the artificial leather, thus producing another mashing dough consisting of the mixture of a polymerizable with a high molecular weight material or swellable in water, and then the assembly is gelled at 170ºC in the tensioner frame.
