    • A base for synthetic leather comprising a nonwoven fabric structure made of ultrafine-denier fiber bundles and a polymeric elastomer contained therein, which satisfies all of the following four requirements: (1) the ultrafine-denier fiber bundles are each composed of on average 6 to 150 gathered ultrafine-denier filaments, (2) the sectional areas of the ultrafine-denier filaments constituting the bundles are 27mum^2 or below and at least 80% of the ultrafine-denier filaments have sectional areas of 0.9 to 25mum^2, (3) the average sectional area of the ultrafine-denier fiber bundles falls within the range of 15 to 150mum^2, and (4) in an arbitrary cross section of the nonwoven fabric structure parallel to the thicknesswise direction thereof, on average 1000 to 3000 cross sections of ultrafine-denier fiber bundles are present per square millimeter. Plush-tone synthetic leathers or silver-clad-tone ones made by using the base are excellent in the characteristics that conventional leathers could not attain.
    • 一种合成革的基材,其包含由超细旦尼尔纤维束制成的非织造织物结构和其中包含的聚合物弹性体,其满足以下四个要求:(1)超细旦纤维束平均为6至 150聚集的超细旦丝,(2)构成束的超细旦长丝的截面积为27m 2/2或以下,超细旦丝的至少80%的截面积为0.9〜25mum ^ 2( 3)超细旦纤维束的平均截面积在15〜150m ^ 2的范围内,(4)无纺布结构的厚度方向平行的任意截面平均为1000〜3000 超细旦纤维束的横截面存在于每平方毫米。 通过使用基材制成的绒毛合成革或银包色,具有优异的传统皮革无法达到的特性。
