Composite filament textile and environment-friendly composite filament artificial leather manufactured using the same

Abstract

An environmental-friendly composite filament artificial leather includes a composite filament textile and an elastomer film. The composite filament textile is made of composite filament. The composite filament includes at least one core portion and a sheath portion. The at least one core portion is a polyester-type polymer, a polyamide polymer or a polypropylene polymer. The sheath portion sheathes the at least one core portion, and the sheath portion is a thermoplastic elastomer. The elastomer film is bonded with the composite filament textile. The elastomer film is made of one selected from the following materials: thermoplastic polyurethane (TPU), thermoplastic polyester elastomer (TPEE) and thermoplastic polyolefin (TPO). By this way, an environment-friendly artificial leather of lightweight, good abrasion, good touch feeling and well dimentional stability can be manufactured. Furthermore, the artificial leather can be manufactured without use of any solvent, so as to conform to the environment protection requirement.

What is claimed is: 
     
         1 . An environmental-friendly composite filament artificial leather, comprising:
 a composite filament textile, which is made of composite filament, wherein the composite filament includes at least one core portion and a sheath portion, the at least one core portion is a polyester polymer, a polyamide polymer or a polypropylene polymer, the sheath portion sheathes the at least one core portion, and the sheath portion is a thermoplastic elastomer; and   an elastomer film bonded with the composite filament textile, wherein the elastomer film is made of one selected from the following materials: thermoplastic polyurethane (TPU), thermoplastic polyester elastomer (TPEE) and thermoplastic polyolefin (TPO);   wherein the elastomer film is a non-foamed film, and the thickness of the non-foamed film is 0.1 to 2.0 mm inclusive.   
     
     
         2 . The environmental-friendly composite filament artificial leather of  claim 1 , wherein the composite filament textile is in a woven or nonwoven form. 
     
     
         3 . The environmental-friendly composite filament artificial leather of  claim 1 , wherein the elastomer film and the composite filament textile are bonded in one manner selected from the following: bonding by using an water-based adhesive with a solid content of 5-55% inclusive, and bonding by directly performing hot-pressing at a temperature ranging from 90 to 180° C. inclusive.
