  • Patent number: 10689800
    Abstract: Disclosed is a nubuck-finished leather-like sheet including a non-woven fabric that is an entangled body of ultrafine filaments, wherein the non-woven fabric includes a napped surface having napped fibers formed thereon, and the napped fibers are fixed to an acrylic resin on the napped surface while being laid down. Preferably, the acrylic resin is present so as to retain voids in the napped surface, while being made malleable.
    Type: Grant

  • Publication number: 20110020590
    Abstract: An aspect of the invention is a split leather product provided with a base material comprising split leather, and a skin layer laminated on a surface of the base material. The skin layer comprises a composite body of an entangled nonwoven fabric formed from microfine fibers, and a polymeric elastomer that impregnates the gaps in the entangled nonwoven fabric. The entangled nonwoven fabric in such a split leather product has the effect of increasing physical strength without detracting from a leather-like texture, in the same way as the longitudinally and transversally crisscrossing collagen fibers in the reticular layer. It is thus possible to obtain a split leather product that resembles leather not only in outward appearance but also in the feel derived from wrinkles and the like resulting when the leather is bent.
