Patent number: 8445391Abstract: A leather-like sheet composed of a microfine-fiber entangled body made of bundles of microfine fibers and an elastic polymer impregnated therein. The bundles of microfine fibers are composed of microfine monofibers having an average cross-sectional area of 0.1 to 30 ?m2 and have an average cross-sectional area of 40 to 400 ?m2. The bundles of microfine fibers exist in a density of 600 to 4000/mm2 on a cross section taken along the thickness direction of the microfine-fiber entangled body. The elastic polymer contains 30 to 100% by mass of a polymer of ethylenically unsaturated monomer. The polymer of ethylenically unsaturated monomer is composed of a soft component having a glass transition temperature (Tg) of less than ?5° C., a crosslinkable component, and optionally a hard component having a glass transition temperature (Tg) of higher than 50° C. and another component. The polymer of ethylenically unsaturated monomer is bonded to the microfine fibers in the bundles of microfine fibers.Type: GrantFiled: September 28, 2006Date of Patent: May 21, 2013Assignee: Kuraray Co., Ltd.Inventors: Kimio Nakayama, Tsuyoshi Yamasaki, Nobuo Takaoka, Jiro Tanaka

Publication number: 20130055535Abstract: A method of producing a substrate suitable for artificial leathers. The substrate is composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate having the surface substantially free from the binder resin. The peeling strength between the substrate and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate is substantially free from the binder resin.Type: ApplicationFiled: November 2, 2012Publication date: March 7, 2013Inventors: Michinori FUJISAWA, Jiro Tanaka, Yoshiyuki Ando, Norio Makiyama
