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.

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.

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.

摘要： A process for the production of artificial leather which comprises coating or impregnating a fibrous base material for the production of artificial leather with an aqueous emulsion of a polymer exhibiting elasticity in a solid state and subjecting the resulting base material to both wet heat (utilizing heat of water vapor) and irradiation with microwave to solidify the emulsion. As this process can dispense with an organic solvent, it is friendly to the environment, is reduced in the migration as compared with the conventional dry-heat solidification processes using hot air, and can give an artificial leather which has distinct voids (noncontact areas) indispensable to the feeling of artificial leather between the fibers of the base material and the polymer incorporated into the material, is excellent in air permeability by virtue of innumerable extremely fine pores formed when the water vapor generating in the solidification passes therethrough, and contains pores also in the polymer solidified in the base material. This process can dispense with also the shrinking step which has been essential in the prior art, thereby simplifying the production process, and can be shortened in the processing time so as to enhance the production efficiency.

摘要： Artificial leather can be produced, without using any organic solvent, by coating or impregnating a fibrous base material to be formed into artificial leather with a polymer solution in the form of an aqueous emulsion, in which the polymer exhibits elasticity when it is solidified and adhered to the base material; and then solidifying and adhering or fixed, in the fibrous base material, the polymer solution contained in the base material using a combination of wet heat (using the heat of water vapor) and microwave heating. Therefore, the method is not harmful to the environment and permits the reduction of the degree of migration as compared with the conventional methods in which the solidification and adhesion or fixation are performed by dry heating while making use of hot air. The method also permits the formation of a product having clear voids (contact-free portions) formed between fibers in the fibrous base material and the impregnated polymer, the voids being indispensable to the handling or feeling of the artificial leather. The resulting product further has gas permeability due to the presence of numerous very fine pores formed by the release of water vapor generated during the solidification and adhesion or fixation of the polymer. There is also observed the presence of porous structures in the polymer solidified and adhered or fixed within the fibrous base material. In addition, the method permits the elimination of the shrinking step which is essential for the conventional processing steps and this correspondingly allows the simplification of the production process. Moreover, the method of the invention permits the reduction of the processing time and the improvement of the production efficiency.
