Beschreibung
Zusammenfassung:Provided is artificial leather which has excellent flexible texture, wear resistance, and nubuck outer surface having a dense feeling. The present invention relates to napped artificial leather containing an entangled sheet, and a polymer elastomer filled into the entangled sheet, the napped artificial leather being characterized in that: the entangled sheet has a structure of two or more layers formed from a fiber layer (A) on the front surface side of the napped artificial leather, and a scrim in contact with the fiber layer (A); the average diameter of the fibers constituting the fiber layer (A) is 2.0-7.0 µm; and when measuring porosity in the thickness direction and defining the minimum porosity in the fiber layer (A) as εAmin(%), the minimum porosity in the scrim as εSmin(%), and the maximum porosity from the position of the εAmin(%) to the position of the εSmin(%) as εA-Smax(%), 40≤εAmin≤70, 70≤εA-Smax≤90, and εSmin(%)
