摘要 |
An artificial grain leather sheet free of rubber-like elasticity and characterized by excellent softness and strength composed of ultrafine super-entangled synthetic fibers having a denier of less than about 0.5 and a resin. The sheet has a body portion and a grain surface portion wherein the ultrafine fibers are supertangled at a multiplicity of entangling points, with the average distance between entangling points being less than about 200 microns and the fiber density coefficient near the surface being greater than about 30.
