Suede type artificial leather with antifouling property and preparation method therefor

Abstract

A suede type artificial leather having an antifouling property is provided. A polymeric elastomer is impregnated in a nonwoven fabric formed by three-dimensionally interlacing ultrafine fibers and raising is formed, wherein the polymeric elastomer is a fluorine-containing modified polyurethane, and the fluorine-containing modified polyurethane is obtained by a polymerization of a urethane prepolymer having isocyanate groups at terminals, obtained by reacting a diol and a diisocyanate, and a fluorinated carbon compound having hydroxy functional groups at both terminals. The fluorine-containing modified polyurethane has a weight average molecular weight of 500,000 to 800,000. The suede type artificial leather is prepared by using the fluorine-containing polyurethane elastomer.
