Zusammenfassung: | PURPOSE: To obtain a high-quality artificial leather excellent in balance of elongation, hardly causing deformation of a product in processing, further, excellent also in durability (resistance to hydrolysis) and to provide a method for producing the artificial leather. CONSTITUTION: This artificial leather is obtained by impregnating and/or coating a nonwoven fabric with a solution of a polyurethane resin, carrying out wet coagulation of the polyurethane resin and subjecting the treated nonwoven fabric to surface finishing and the nonwoven fabric is obtained by subjecting a divided type conjugate fiber web obtained by combining different fibers or a web obtained by blending the divided type conjugate fiber web with a non- dividing type fiber to spun lace finishing, and the polyurethane resin is a polyurethane resin consisting essentially of a polyester-based polyurethane resin. A fluorine-containing polyurethane resin in an amount of 0.1-3.0 pts. wt. based on 100 pts.wt. of the polyester-based polyurethane resin is blended as the polyester-based polyurethane resin. |
