Document Type and Number:
WIPO Patent Application WO/2005/106108
Kind Code:
A1
Abstract:
An artificial leather with a silvered tone which comprises a base layer and a coating layer (Y) formed on one side of the base layer. The base layer comprises an interlacing nonwoven fabric (X) made of bundles of microfine fibers having an average single-fiber fineness of 0.07 dtex or smaller and a polymeric elastomer (A) and a polymeric elastomer (B) each infiltrated in inner parts of the fabric (X). The interlacing nonwoven fabric (X) comprises a lower layer (XA) and an upper layer (XB). Mainly the polymeric elastomer (A) has been infiltrated in the lower layer (XA) substantially in the state of being not bonded to the microfine-fiber bundles. Mainly the polymeric elastomer (B) has been infiltrated in the upper layer (XB) substantially in the state of being not bonded to the microfine-fiber bundles. The coating layer (Y) is composed of a 1-10 μm-thick coating layer (YB) of the polymeric elastomer (B) formed on the upper layer (XB), a coating layer (YC) of a polymeric elastomer (C) formed on the coating layer (YB), and a finish layer (YE) formed on the coating layer (YC). The artificial leather with a silvered tone, which has such structure, combines an excellent appearance similar to those of natural leathers with excellent softness, flexibility, and high peel strength.
