Abstract
A suede-like artificial leather which is composed of fiber bundles and an elastomeric polymer, has fibrous nap on its surface and is dyed, said fiber bundles being composed of fine fibers (A) having a finess of 0.02-0.2 denier and microfine fibers (B) having a fineness not more than 1/5 of the average fineness of said fine fibers (A) and also less than 0.02 denier, said fibers (A) and (B) being substantially uniformly dispersed in cross sections of the fiber bundles, the ratio between the strand numbers of fibers (A) to fibers (B) ranging from 1/2 to 2/3, said fiber bundles not substantially containing the elastomeric polymer in the interspaces among the individual fibers constituting each of the fiber bundles, and the ratio of the number of fibers (A) to that of fibers (B) in the nap-constituting fibers being at least 3/1, is provided. The artificial leather has good appearance and hand and excels in color-developing property and pilling resistance, and is useful for making cloths, shoes, pouches, gloves and the like.
