    摘要: A substrate for artificial leathers which is composed of a nonwoven fabric made of fiber bundles of microfine fibers having an average single fiber fineness of 0.5 dtex or less and an elastic polymer impregnated into the nonwoven fabric. The substrate for artificial leathers satisfies the following requirements 1 and 2: (1) the number of fiber bundles which are oriented to a thickness direction of the nonwoven fabric is 75 to 300 per 1 cm of width which is perpendicular to the thickness direction, when measured on a cross section parallel to the thickness direction; and (2) the number of cross sections of the fiber bundles which are oriented to the thickness direction is 30 to 800 per 1 mm 2 , when measured on a cross section perpendicular to the thickness direction. The substrate for artificial leathers is suitable for the production of a grain-finished artificial leather which combines a non-repulsive softness and firm hand resembling natural sheep leathers and has fine buckling wrinkles, and a suede-finished or nubuck artificial leather having a surface touch with fine texture and a grace writing effect each being hitherto not obtained.
