    摘要： The present invention relates to a suede type artificial leather having antifouling property in which a polymeric elastomer is impregnated in a nonwoven fabric formed by three-dimensionally interlacing ultrafine fibers and raising is formed, wherein the polymeric elastomer is a fluorine-containing modified polyurethane, and the fluorine-containing modified polyurethane is a product obtained by a polymerization reaction between a urethane prepolymer having isocyanate groups at terminals, obtained by reacting a diol and a diisocyanate, and a fluorinated carbon compound having hydroxy functional groups at both terminals, and has a weight average molecular weight (Mw) of 500,000 to 800,000. According to the present invention, the suede type artificial leather is prepared by using a fluorine-containing polyurethane elastomer having antifouling property during the preparation of the artificial leather, thus a separate fluorine-based surfactant for an antifouling property does not need and the surface change with the passage of time of the artificial leather caused by using a fluorine-based surfactant does not occur.

    摘要： An artificial leather which has a surface structure such that short piles are densely present with an extremely decreased orientation and therefore exhibits good nubuck-type appearance and feeling; and a process for the production thereof. The artificial leather is produced by applying an elastic polymer to entangled ultrafine-denier fibers and having piles of the fibers on at least one surface thereof, has an apparent density of 0.3 g/cm or above and a pile length of 0.5 mm or below, and exhibits an R value of 25 % or below as determined from the reflection vs. angle curve measured with an automatic goniophotometer by rotating the piled surface from 0 to 180 DEG . The production process comprises ap plying an elastic polymer to entangled ultrafine-denier fibers, solidifying the elastic polymer substantially, immersing the resulting sheet in a swelling agent for the elastic polymer to swell the polymer, compressing the resulting sheet in the thickness-wise direction, removing the swelling agent from the sheet with an aqueous solvent, and raising at least one surface of the sheet.

    摘要： The present invention relates to an artificial leather having nap very little oriented on the surface and having short fibers densely, and hence having a good nubuck-like look and hand, and also relates to a production process thereof. The present invention provides an artificial leather having a nap surface of ultra-fine fibers at least on one side, which is formed by applying an elastic polymer to an ultra-fine fiber-entangled substrate, characterized by being 0.3 g/cm 3 or more in the apparent density of the artificial leather, being 0.5 mm or less in the nap length, and being 25% or less in the R value obtained from the goniometric reflectance distribution measured with the nap surface rotated from 0 degree to 180 degrees using a goniophotometer. The present invention also provides a process for producing a nubuck-like artificial leather, in which a sheet obtained by applying an elastic polymer to an ultra-fine fiber-entangled substrate is raised to produce a napped sheet, comprising the steps of applying an elastic polymer to an ultra-fine fiber-entangled substrate, substantially solidifying the elastic polymer, immersing the polymer-deposited fiber-entangled substrate into a swelling agent of the elastic polymer, to swell the elastic polymer, compressing the sheet in the normal direction of the sheet, removing the swelling agent by an aqueous solvent, and raising the sheet at least on one side.
