摘要： 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.

摘要： 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.
