摘要： The invention provides artificial leather having texture very similar to that of natural leather and a base for the artificial leather at low cost. The processes for the production of the artificial leather and the base are characterized by piling up successively a dry surfacing web produced by a wet process and comprising both an aggregate of fibers having a fineness of 1 denier or below, a fiber length of 3 to 15mm and a basis weight of 20 to 150g/m2 and a water-soluble polymer applied thereto, a fabric made of fiber having a fineness of 1 denier or above and having an air permeability of 3 to 250 cm3/cm2 ⋅ s as determined according to JIS-L1096A, and a dry backing web produced by a wet process and comprising both an aggregate of fibers having a fineness larger than that of the surfacing web, a fiber length of 5 to 25 mm and a basis weight of 50 to 200g/m2 and a water-soluble polymer applied thereto at a density higher than that of the surfacing web, subjecting the resulting laminate to water jet entanglement, and impregnating the obtained nonwoven fabric with an elastic polymer solution.

摘要： A sheet of an artificial leather substrate contains an upper-layer nonwoven fabric A (1) and a base nonwoven fabric B (2). The upper-layer nonwoven fabric A (1) is a wet-laid nonwoven fabric having a density of 0.30 to 0.50 g/cm 3 and being produced with synthetic fibers in which the component fibers have a fineness of 0.005 to 1.1 dtex, a fiber length of 3 to 10 mm and a weight per unit area of 20 to 150 g/m 2 , and the base nonwoven fabric B (2) is a layer of a nonwoven fabric having a density of 0.15 g/cm 3 or more and less than 0.28 g/cm 3 and being produced with synthetic fibers in which the component fibers have a fineness greater than that of the component fibers of the upper-layer nonwoven fabric A and 4.5 dtex or less, a fiber length of 2 to 15 mm and a weight per unit area of 50 to 400 g/m 2 . The upper-layer nonwoven fabric A (1) and the base nonwoven fabric B (2) are layered, made into a single body by entanglement of the component fibers of both layers and impregnated with an elastic polymer. Thus, artificial leather having a texture similar to natural leather and a substrate for use therein are provided at low cost.

摘要： An artificial leather that feels like natural leather and a substrate for artificial leather are provided at low cost. A method for manufacturing the substrate for artificial leather includes the following: laminating an upper layer web, a fabric, and a lower layer web in the indicated order; subjecting the resultant laminate to hydroentanglement to form a non-woven fabric; and impregnating the non-woven fabric with an elastic polymer solution. The upper layer web is obtained by wet papermaking and drying, and includes a group of fibers having a fineness of 1 denier or less, a fiber length of 3 to 15 mm, and a basis weight of 20 to 150 g/m 2 and a water-soluble polymer. The fabric includes fibers having a fineness of 1 denier or more and has an air permeability of 3 to 250 cm 3 /cm 2 ·sec based on JIS L 1096 Method A. The lower layer web is obtained by wet papermaking and drying, and includes a group of fibers having a fineness greater than that of the upper layer web, a fiber length of 5 to 25 mm, and a basis weight of 50 to 200 g/m 2 and a water-soluble polymer filled into the lower layer web at a density higher than that of the upper layer web.
