<p>A fibrous substrate for artificial leather, comprising microfine fiber bundles, each of which is composed of 3-50 microfine fibers (A) comprising an elastic polymer and having an average fineness of 0.5 denier or less and 15 or more microfine fibers (B) comprising a non-elastic polymer and having an average fineness of 0.2 denier or less, the microfine fiber bundles satisfying the following conditions (1)-(3): (1) the ratio of the number of strands of the A to the number of strands of the B in cross sections of the bundles (A/B) is 1/5 or less, (2) the ratio of the weight of the A to the weight of the B in the bundles (A/B) is 10/90-60/40, and (3) the microfine fibers (B) comprising the non-elastic polymer encircle each of the microfine fibers (A) comprising the elastic polymer. It is possible to obtain, from the fibrous substrate, suede-like artificial leather and grain-like artificial leather having texture and appearance like natural leather, and having high-class feeling never available from artificial leather in the prior art.</p> |
