More Information
Summary:The leather-like sheet of the invention comprises a napped part of ultrafine fibers and a grainy part of nonporous elastic polymer randomly existing in the surface of a substrate prepared by infiltrating a porous polymer elastomer into a three-dimensionally intermingled nonwoven fabric of ultrafine fibers of not more than 0.5 dtex, and this is characterized in that the nonporous elastic polymer is infiltrated into the substrate to a depth thereof of from 5 to 20 mu m from the surface of the substrate. The production method of the invention is for producing a nubuck-type leather-like sheet of good surface abrasion resistance. A grainy part of resin and ultrafine fibers and a part of the ultrafine fibers are mingled on the surface of the substrate, and the sheet has an elegant and three-dimensional appearance like natural leather.
