Abstract
A leather-like sheet material comprising a substrate layer composed of an entangled nonwoven fabric consisting of ultrafine fibers and an elastic polymer or elastomer filled therein and having, on one side (side A) of the substrate layer, a grain layer comprising an elastomer mainly consisting of a polyurethane, wherein the ultrafine fibers (a) constituting the side A of the substrate layer have a mean fineness substantially within the range of 0.01 to 0.5 decitex and the ultrafine fibers (b) substantially constituting the other side (side B) opposite to the side A of the substrate layer have a mean fineness of not more than ½ of the mean fineness of the ultrafine fibers (a).
Claims25
A leather-like sheet material comprising:
- a substrate layer comprising an entangled nonwoven fabric comprising ultrafine fibers and an elastic polymer or elastomer filled therein, and
- wherein one side (side A) of the substrate layer is overlayed with a grain layer comprising an elastomer mainly consisting of a polyurethane, and
