Abstract: A napped leather-like sheet material comprising an entangled nonwoven fabric composed of ultrafine fibers and an elastomer contained therein and having a nap made of ultrafine fibers on one or both sides thereof, which material is provided with a silk protein substance and a softening agent on the surface portion of the napped face or faces; and a method of producing the above napped leather-like sheet material which comprises applying a liquid containing a silk protein substance and a softening agent to the surface of a napped leather-like sheet material by, for example, a gravure printing or spraying technique.

Abstract: An abrasive sheet for texturing of magnetic recording media which comprises an entangled ultrafine fiber nonwoven fabric made of three-dimensionally entangled ultrafine fiber bundles composed of ultrafine fibers (A) and a high-molecular elastomer occurring in a porous state in spaces among the entangled ultrafine fibers, with the high-molecular elastomer occurring therein without substantially confining most of the ultrafine fiber bundles and which is characterized in that there is a nap consisting of ultrafine fibers (B) having a fineness of not more than 0.03 dtex on at least one side of that sheet is excellent in precision and stability in processing.
