ABSTRACT:
A high durability composite textile material, like a synthetic suede, is prepared according to a procedure that comprises the impregnation of micro-fibers non-woven fabric substrate with a polyurethane-polyurea solution. This polymer solution, is made by a pre-polymerization phase between diisocyanate and polyols, a dilution phase of the pre-polymer thus obtained and an extension step of the pre-polymer, the extension of the pre-polymer free isocyanate groups is carried out by means water addition.
