Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . An artificial leather, comprising: a substrate, wherein the substrate is formed from fibers, the fibers have a first thermoplastic ethylene-propylene copolymer, and a melting point of the substrate is 125° C. to 152° C., a hardness of the substrate is 70 A; a thermoplastic ethylene-propylene copolymeric elastic layer, disposed on the substrate; and a surface coating layer, disposed on the thermoplastic ethylene-propylene copolymeric elastic layer, wherein the surface coating layer is formed from a second thermoplastic ethylene-propylene copolymer, and a melting point of the surface coating layer is 60° C. to 100° C., the melting point of the substrate is higher than the melting point of the surface coating layer. 2 . The artificial leather of claim 1 , wherein a thickness of the surface coating layer is 0.01 mm to 0.05 mm. 3 . The artificial leather of claim 1 , wherein the surface coating layer has a surface texture. 4 . The artificial leather of claim 1 , wherein the surface coating layer has a treated surface.
