Microporous sheet, substrate for artificial leather using said sheet, and process for production of said sheet |
摘要 |
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.
