Artificial leather and its manufacturing method

Abstract

The objective of this invention is to provide artificial leather with a beautiful and high-end appearance, high strength, and excellent softness. This invention relates to an artificial leather comprising a long-fiber nonwoven fabric composed of thermoplastic resin fibers belonging to the category of coiled fibers, wherein one side of the surface of the artificial leather has a piled portion and / or a resin layer, and with respect to portions PS1, PC, and PS2 of a cross-section parallel to the thickness direction of the artificial leather, the following formulas 1 to 4 are satisfied. 1.4×φPS1≦φPC≦4.0×φPS1 …(Equation 1) 0.05≦rPS1≦0.20 …(Equation 2) 0.05≦rPS2≦0.20 …(Equation 3) 0.05≦rPC≦0.20 …(Equation 4) Here, φPS1 and φPC are the average equivalent circle diameters (μm) of the thermoplastic resin fibers in the PS1 and PC portions, and rPS1, rPC, and rPS2 are the curvatures of the thermoplastic resin fibers in the PS1, PC, and PS2 portions.
