Grain-finished artificial leathers

Abstract

A grain-finished artificial leather composed of a base layer and a coating layer Y formed on one of the surfaces of the base layer. The base layer is composed of an entangled nonwoven fabric X made of bundles of microfine fibers having an average single fiber fineness of 0.07 dtex or less and impregnated with a polymeric elastomer A and a polymeric elastomer B. The entangled nonwoven fabric X is composed of a lower layer XA and an upper layer XB wherein the lower layer XA is impregnated mainly with the polymeric elastomer A which is substantially not adhered to the bundles of microfine fibers and the upper layer XB is impregnated mainly with the polymeric elastomer B which is substantially not adhered to the bundles of microfine fibers. The coating layer Y is composed of a coating layer YB having a thickness of 1 to 10 μm which is made of the polymeric elastomer B and formed on the upper layer XB, a coating layer YC which is made of a polymeric elastomer C and formed on the coating layer YB, and a finished layer YE which is formed on the coating layer YC. The grain-finished artificial leather having the above structure combines a natural leather-like, delicate appearance, a good softness and flexibility, and a high peel strength.
