<P>PROBLEM TO BE SOLVED: To provide a nonwoven fabric for artificial leather and an artificial leather using the aforementioned nonwoven fabric which combine excellency in feeling, high abrasion resistance, cutting ability and shape stability, without the impregnation of any elastomer such as polyurethane resin. <P>SOLUTION: A nonwoven fabric for artificial leather having a multilayer structure of at least 2 layers or more comprised of a surface fiber layer and a scrim layer, which is a woven and knitted fabric, has the following characteristics: (1) The surface fiber layer is composed of at least one or more main short fibers and a thermo-fusible short fiber having a melting point that is 20°C or more lower than the melting point of the main short fiber. (2) In the surface fiber layer, the mixing ratio of the thermo-fusible short fiber to the sum of the thermo-fusible short fiber and the main short fiber is in the range of 5 to 25%. (3) A part of, or all of the thermo-fusible short fiber is subjected to interfiber bonding by thermofusion. (4) The surface short fiber layer and the scrim layer are interlaced and structurally-integrated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
