  • Publication number: 20180245282
    Abstract: Provided is a nubuck-like artificial leather having a moist feel and nap close to those of natural leather, and superior abrasion resistance. A nubuck-like artificial leather 100 is provided with a flexible sheet 100? including a base material containing tangled fibers 10 to which a resin 20 is added. Voids 30 are formed in the flexible sheet 100?, the voids 30 being surrounded by cross-sections of the fibers 10 as viewed in a cross-section parallel to a thickness direction of the flexible sheet 100?, and the voids being held by the fibers 10 being bonded together by the resin 20. In a region having a unit area of the cross-section of the flexible sheet 100?, a ratio (A/B) of a cross-sectional area (A) of a continuous structure 40 formed by the fibers 10 being bonded together by the resin 20 to a cross-sectional area (B) of the voids is 15/85-90/10.
