<p>An artificial leather which has a surface structure such that short piles are densely present with an extremely decreased orientation and therefore exhibits good nubuck-type appearance and feeling; and a process for the production thereof. The artificial leather is produced by applying an elastic polymer to entangled ultrafine-denier fibers and having piles of the fibers on at least one surface thereof, has an apparent density of 0.3 g/cm3 or above and a pile length of 0.5 mm or below, and exhibits an R value of 25 % or below as determined from the reflection vs. angle curve measured with an automatic goniophotometer by rotating the piled surface from 0 to 180°. The production process comprises ap plying an elastic polymer to entangled ultrafine-denier fibers, solidifying the elastic polymer substantially, immersing the resulting sheet in a swelling agent for the elastic polymer to swell the polymer, compressing the resulting sheet in the thickness-wise direction, removing the swelling agent from the sheet with an aqueous solvent, and raising at least one surface of the sheet.</p> |
