    IPC: D06N3/00

    Abstract: PURPOSE:An artificial leather having a specific relationship between a void ratio, water permeability, and water vapor transmission, having improved appearance, feeling, resistance to scratching, mechanical strength and comfortableness, comprising a fiber structure of finely entangled extremely thin fibers and/or their bundles, and a resin existing in the void parts of them. CONSTITUTION:A sheet like leather having at least one silver face layer made of a composite material consisting of a fiber structure wherein extremely thin fibers having =2,500g/cm .24hr, especially >=3,000g/m .24hr water vapor transmission rate, and .minute, especially .minute water permeability. Preferably the lower layer of the silver face layer consists essentially of the entangled bundles of the extremely thin fibers, and the silver face layer has a structure wherein extremely thin fibers (bundles) branched from the fiber bundles are further finely entangled.

    Abstract: PURPOSE:An extremely thin leathery sheet having flexibility and feeling of good touch, having a fibrous structure of extremely thin fiber (bundle) entangled in three-dimensional state, having a surface skin layer of the fiber densely entangled on at least one side of the structure. CONSTITUTION:A sheet having a fibrous structure of extremely thin fibers having =0.3g/cm , especially >=0.35g/cm aparent density (increased feeling of good touch), =3kg/cm tensile strength. A leathery sheet having improved strength and durability is obtained without providing a base material layer with an elastic polymer as reinforcement.
