Abstract:
Disclosed is a napped artificial leather including: a fabric that has been impregnated with a first elastic polymer and that has a napped surface including napped ultrafine fibers with an average fineness of 0.01 to 0.5 dtex, wherein the napped surface has, as measured by a surface roughness measurement in accordance with ISO 25178, an arithmetic mean height (Sa) of 30 μm or less in both a grain direction and a reverse grain direction, and a density of peaks (Spd) having a height of 100 μm or more from a mean height, of 30/432 mm2 or less in both of the grain direction and the reverse grain direction, and a difference (absolute value) in the density of peaks (Spd) between the grain direction and the reverse grain direction is 20/432 mm2 or less.
