发明名称 LEATHER-LIKE SHEET BEARING GRAIN FINISH AND PROCESS FOR PRODUCING THE SAME
摘要 A (semi)grain-finished leather-like sheet composed of an entangled nonwoven fabric of three-dimensionally entangled fiber bundles containing microfine long fibers and an elastic polymer contained in the entangled nonwoven fabric. When dividing the (semi)grain-finished leather-like sheet to five layers with equal thickness, i.e., surface layer, substrate layer 1, substrate layer 2, substrate layer 3 and back layer in this order along the thickness direction, part of the microfine long fibers forming the surface layer and/or the back layer are fuse-bonded to each other and the microfine long fibers forming the intermediate layer are not fuse-bonded. With such a fuse-bonding state of the microfine long fibers, the (semi)grain-finished leather-like sheet combines a low compression resistance and a dense feel each comparable to natural leathers, has a sufficient practical strength, and are excellent in properties which are required according to its use.
