Title:
BASE MATERIAL FOR ARTIFICIAL LEATHER AND GRAINED ARTIFICIAL LEATHER
Document Type and Number:
WIPO Patent Application WO/2007/138931
Kind Code:
A1
Abstract:
A base material for artificial leather comprising a nonwoven fabric made of entangled ultrafine-denier fibers and a binder resin, characterized in that at least one surface of the base material is constituted of a dense layer made of ultrafine-denier fibers substantially free from the binder resin and that excepting the dense layer, the base material is impregnated with the binder resin. By virtue of the presence of the dense layer, the binder resin impregnated into the nonwoven fabric is inhibited from migrating to the surface of the fabric, whereby a base material for artificial leather which has a surface substantially free from binder resin can be obtained. Since substantially no binder resin is present on the surface of the base material, the peel strength between the base material and a grain layer formed thereon can be remarkably improved.
