Abstract

A method for forming a composite stratiform element with fibrous surface, said element consisting of a layer of non-woven fabric based on artificial fibers and, or, synthetic blended polyurethane material, of thickness between 0.1 and 10 mm having a density between 0.85 and 1.25 g per cm3, a hardness comprised between 85 and 95 share a and a breaking load between 1.5 and 2.5 kg per mm2, characterized in that it comprises the phases of subjecting at least one surface of a layer of a non-woven fabric, preferably previously treated with a bath of impregnation based on altopolymer and dried, said layer having a bulk density comprised between 0.10 and 0.60 g per cm 3, a a smearing operation using a urethane composition crosslinkable with moisture, having a viscosity at room temperature between 08,000 and 60,000 centipoise, based on urethane prepolymer with isociety groups free amersions, of subjecting the resulting assembly to a sufficient pressing operation so that said urethane composition penetrates within the fibers of the non-woven fabric layer, and for a period of time sufficient for said urethane composition to at least partially cross-link, and finally carry out the finishing operations on the composite stratiform element obtained.
