Abstract: The present invention provides an artificial leather including an entangled fiber mass of ultrafine fibers having a monofilament fineness of 0.01 dtex or more and 0.50 dtex or less and a polymeric elastomer; wherein at least one surface is napped; the cross-sectional profile curve of the napped surface has an arithmetic mean height Pa of 26 μm or more and 100 μm or less; the arithmetic mean height Pa of the cross-sectional profile curve of the opposite surface is 20% or more and 80% or less of the cross-sectional roughness Pa of the napped side; the existence frequency of asperity peaks found in the cross-sectional profile curve of the napped surface is 1.8 or more and 20 or less per 1.0 mm; and a woven or knitted fabric lamination is present near the opposite surface at a depth position of 10% or more and 50% or less.

Abstract: A leather-like fabric has a feel of natural nubuck leather and a napped feel and air permeability of suede leather, as well as high wear resistance. The leather-like fabric includes a fibrous structure including ultrafine fibers having an average monofilament fineness of 0.0001 dtex or more and 0.5 dtex or less, at least one surface of the fibrous structure being napped, the napped surface having resin layers located discontinuously, and each of the resin layers containing two or more layers.

Abstract: A dyed artificial leather includes a fibrous base containing ultrafine fibers with a filament fineness of 2 decitex or less and a polymeric elastomer, and characterized in that the lightness difference ΔL* between the ultrafine fibers and the polymeric elastomer represented by the following equation meet the requirement of −16≤ΔL*≤5: ΔL*=(average lightness L* of ultrafine fibers)−(average lightness L* of polymeric elastomer). A production method for dyed artificial leather includes a first dying step in which artificial leather constituted mainly of a fibrous base containing ultrafine fibers with a filament fineness of 2 decitex or less and a polymeric elastomer is dyed using a dye and a subsequent second dyeing step performed at a dye concentration that is 0.1% to 30% of the dye concentration (owf) in the first dyeing step.
