摘要： 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.
摘要翻译：由纤维束和弹性体聚合物组成的绒面革人造革在其表面上具有纤维状的绒毛并被染色，所述纤维束由具有0.02-0.2旦尼尔的微细纤维（A）和微细纤维（ B）具有不超过所述细纤维（A）的平均细度的1/5且小于0.02旦尼尔的纤度，所述纤维（A）和（B）基本均匀地分散在纤维束的横截面中，所述纤维（A）与纤维（B）的股线数之比为1/2至2/3，所述纤维束在构成每个纤维束的各纤维之间的间隙中基本上不包含弹性体聚合物，提供了绒毛构成纤维中的纤维数（A）与纤维（B）的比例为3/1以上的比例。人造革具有良好的外观和手感，并且在显色性和抗起毛性方面优异，并且可用于制造布，鞋，袋，手套等。
