A porous sheet is provided suitable for use as a substitute for natural leather for shoes, clothes, and a fiber composite sheet. The porous sheet is formed of an elastic polymer, has a thickness of 10 to 500 &#x3bc;m, and has 500 to 15,000 fine pores mminside, the fine pores having an average pore diameter of 1 to 20 &#x3bc;m, and which has a breaking strength of 1 to 15 N/mmand a breaking elongation of 100 to 500%. A fiber composite sheet is also provided, wherein the porous sheet is laminated on a substrate made of a fiber aggregate as a main component.

Porous sheet, fiber composite sheet and processes for the production thereof

Non-woven fabric, and sheet and artificial leather produced from the same

A microporous sheet suitably used as a substrate for artificial leather for its good balance in properties such as softness, abrasion resistance and the like, obtained by impregnating a non-woven fabric with an elastic polymer and then coagulating the impregnated polymer, said non-woven fabric being a blend of (a) an aromatic polyester fiber (fiber A) and (b) a polyolefin or aliphatic polyamide fiber (fiber B), which sheet is scattered with portions where the fiber A is surrounded by the elastic polymer in a bonded state and portions where the fiber B is surrounded by the elastic polymer in a not-bonded state.
