US 12,529,185 B2 · Artificial leather and method for producing the same

Abstract

The present invention relates to an artificial leather and a method for producing the same. The artificial leather includes a substrate, a thermoplastic ethylene-propylene polymer elastic layer, and a surface layer. The substrate is formed from fibers having a first thermoplastic ethylene-propylene polymer. The surface layer is formed from a second thermoplastic ethylene-propylene polymer. The first thermoplastic ethylene-propylene polymer and the second thermoplastic ethylene-propylene polymer provide the substrate with a specific melting point and the surface layer with a specific melting point, respectively. By the substrate with the specific melting point and the surface layer with the specific melting point, the artificial leather has an excellent post-processability. Therefore, the artificial leather can have the substrate and the surface layer which have the same material, thereby having an excellent recyclability.
