摘要： A substrate for artificial leathers, comprising a nonwoven fabric body made of microfine fiber bundles and an elastic polymer impregnated therein. The substrate for artificial leathers simultaneously satisfies the following requirements 1 to 4: (1) each of the microfine fiber bundles contains 6 to 150 bundled microfine long fibers in average; (2) a cross-sectional area of the microfine long fibers constituting the microfine fiber bundles is 27 μm2 or less, and 80% or more of the microfine long fibers has a cross-sectional area of from 0.9 to 25 μm2; (3) an average cross-sectional area of the microfine fiber bundles is from 15 to 150 μm2; and (4) on a cross section parallel to a thickness direction of the nonwoven fabric body, cross sections of the microfine fiber bundles exist in a density of from 1000 to 3000/mm2 in average. The raised artificial leathers and grain-finished artificial leathers made from the substrate for artificial leathers are excellent in the properties which are hitherto difficult to be combined.

摘要： 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.

The substrate for artificial leather simultaneously satisfies the following requirements 1 to 4: (1) the bundle of microfine filaments comprises 8 to 70 microfine filaments having a cross-sectional shape of nearly circle; (2) the bundle of microfine filaments has a cross-sectional area of 170 to 700 μm2 and a flatness of 4.0 or less; (3) on a cross section parallel to a thickness direction of the nonwoven fabric body, cross sections of the microfine fiber bundles exist in a density of 1500 to 3000/mm2; and (4) on a cross section parallel to a thickness direction of the nonwoven fabric body, gaps between the microfine fiber bundles have a size of 70 μm or less. By satisfying the requirements, the substrate for artificial leather combines high level of sensuous qualities and high level of physical properties which have been considered to be mutually exclusive.

摘要： A (semi)grain-finished leather-like sheet composed of an entangled nonwoven fabric of three-dimensionally entangled fiber bundles containing microfine long fibers and an elastic polymer contained in the entangled nonwoven fabric. When dividing the (semi)grain-finished leather-like sheet to five layers with equal thickness, i.e., surface layer, substrate layer 1, substrate layer 2, substrate layer 3 and back layer in this order along the thickness direction, part of the microfine long fibers forming the surface layer and/or the back layer are fuse-bonded to each other and the microfine long fibers forming the intermediate layer are not fuse-bonded. With such a fuse-bonding state of the microfine long fibers, the (semi)grain-finished leather-like sheet combines a low compression resistance and a dense feel each comparable to natural leathers, has a sufficient practical strength, and are excellent in properties which are required according to its use.

摘要： A substrate for artificial leathers which is composed of a nonwoven fabric made of fiber bundles of microfine fibers having an average single fiber fineness of 0.5 dtex or less and an elastic polymer impregnated into the nonwoven fabric. The substrate for artificial leathers satisfies the following requirements 1 and 2: (1) the number of fiber bundles which are oriented to a thickness direction of the nonwoven fabric is 75 to 300 per 1 cm of width which is perpendicular to the thickness direction, when measured on a cross section parallel to the thickness direction; and (2) the number of cross sections of the fiber bundles which are oriented to the thickness direction is 30 to 800 per 1 mm2, when measured on a cross section perpendicular to the thickness direction. The substrate for artificial leathers is suitable for the production of a grain-finished artificial leather which combines a non-repulsive softness and firm hand resembling natural sheep leathers and has fine buckling wrinkles, and a suede-finished or nubuck artificial leather having a surface touch with fine texture and a grace writing effect each being hitherto not obtained.
