る。(Effects) In the method for producing artificial leather according to the present invention, crushed leather powder in the form of particles of 50 to 250 mesh and natural fibers, synthetic fibers, or both fibers are bound by a thermoplastic resin. is bound to the fibers, and each fiber is also bound in a state entangled with leather powder, so that an artificial leather with excellent strength against tension and tearing can be obtained. The surface of the artificial leather is not sanded or otherwise treated, and the surface is protected by a dense thin skin layer, and no fibers or leather powder protrudes from the surface, so the artificial leather surface has a fluffy appearance similar to that of conventional fluffed leather. Moreover, there is no need for surface treatment, which reduces costs accordingly.
