Abstract: The present invention relates to an artificial leather having a nap of low orientation on the surface and short dense fibers, thereby having a good nubuck-like appearance texture and hand. It also relates to a production process thereof. The present invention provides an artificial leather having a nap surface of ultra-fine fibers on at least one side, which is formed by applying an elastic polymer to an ultra-fine fiber-entangled substrate, characterized by being 0.3 g/cm3 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 on at least one side.

Abstract: The fishing materials are designed to be unsuitable for clinging to by living organisms and specified to be covered with many fibres composed of fine fibres of 5 deniers or less ( preferred 1.5 deniers or less ). The fibres are curled and frizzled. The length of the raised fine fibres lies between 0.5 mm and 45 mm. The fishing materials can be ropes or nets having these raised fibres. The materials can be obtained by attaching the raised fibres onto a base material using paste. One of these fishing materials can be a braided rope comprising a core and a sheath with at least the sheath having the raised fine fibres. The fishing materials are produced by the following processes 1) weaving a cloth from raised fine fibres of 5 denier or less, 2) making a string using at least one of the following two treatments a) twisting the cloth with the raised fibres facing outwards and b) covering a core with the cloth with the raised fibres facing the core surface, 3) making a rope or a net from these strings.

Abstract: An artificial leather comprises a fiber tangled component containing an ultrafine fiber and a polymeric elastic material. The ultrafine fiber has a single fiber size of 0.9 or less dtex. The artificial leather has elongation ratio of 15% or more and expansion recovery factor of 80% or more, along longitudinal direction. A polymeric layer is formed on at least one surface of the fiber tangled component. An independent claim is also included for manufacture of artificial leather, which involves shrinking a contractible sheet contracted to 10% or more in the length direction, adhering to at least one side of artificial leather and subsequently removing contractible sheet.

Abstract: Improved ultrafine sheath-core composite fibers and composite sheets composed of these fibers are disclosed. The composite fibers have a fineness of 0.0001 to 0.5 denier and comprises 10 to 70 % of the core having a very high intrinsic viscosity within a specific range and being located at the center of the sheath ant 90 to 30 % of the sheath composed of a polyester copolymerized 1.5 to 8 mole %, based on the total acid component, of 5-sodium(or lithium or potassium) sulfoisophthalte and having a thickness of 0.04 to 2 microns. The composite fibers have a high strength and are dyeable with a cationic dye. When the composite fibers are combined with a elastic material such as polyurethane, suede-like artificial leathers having excellent softness, touch, feel and colour can be obtained.

Abstract: 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/cm3 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~. 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.
