Claims (9)

A leather-like sheet-like material comprising fine fibers existing on the surface of a fiber , which is composed of a nonwoven fabric in which ultrafine fibers having a single fiber fineness of 0.0001 to 0.5 dtex are intertwined with each other . Basis weight 100~550g / ^{m 2,} fiber apparent density 0.230~0.700g / cm ^3, tear strength is 3～50N, and claim 1, characterized by satisfying the following expression (2) leather-like sheet product according to.
Tensile strength (N / cm) ≧ 0.45 × weight per unit area (g / m ² ) −40 (2) 3. The leather-like sheet-like shape according to claim 1, wherein, in the abrasion test in the Martindale method, the weight loss after wearing 20000 times is 20 mg or less and the number of pills is 5 or less. Thing . The leather-like sheet material according to any one of claims 1 to 3 , wherein the leather-like sheet material is substantially made of a fiber material. The leather-like sheet material according to any one of claims 1 to 4 , wherein at least one surface has napping. The leather-like sheet material according to any one of claims 1 to 5 , further comprising a softening agent. The leather-like sheet material according to any one of claims 1 to 6 , wherein the ultrafine fibers are short fibers having a fiber length of 0.1 to 10 cm. After tangling short fibers with a single fiber fineness of 1 to 10 dtex that can generate ultrafine fibers with a single fiber fineness of 0.0001 to 0.5 dtex, a fine fiber is generated to form an ultrafine short fiber nonwoven fabric, Next, a high-speed fluid treatment is performed at a pressure of at least 10 MPa, the materials are entangled again, and then dyed to give fine particles. The method for producing a leather-like sheet-like material according to claim 8 , wherein the raising treatment is performed before the fine particles are applied.
