Breathable artificial leather and its manufacturing method

Abstract

This invention provides a breathable artificial leather and a method for manufacturing the same. The breathable artificial leather includes a substrate layer, a thermoplastic elastomer layer, a thermoplastic elastomer meltblown layer, and a plurality of air channels. The thermoplastic elastomer layer is disposed on the substrate layer. The thermoplastic elastomer meltblown layer is disposed on the thermoplastic elastomer layer and has a surface textured structure. The plurality of air channels penetrate the thermoplastic elastomer layer. Compared with the prior art, the breathable artificial leather of this invention can improve breathability to 1.0-5.0 CFM, while preserving its appearance and maintaining the peel strength required for shoemaking.

Claims

A method for manufacturing breathable artificial leather, comprising: (a) providing a thermoplastic elastomer meltblown layer; (b) impregnating and coloring the thermoplastic elastomer meltblown layer; (c) bonding the colored thermoplastic elastomer meltblown layer to a thermoplastic elastomer layer; (d) forming a plurality of air channels penetrating the thermoplastic elastomer meltblown layer and the thermoplastic elastomer layer; (e) bonding a substrate layer to the lower surface of the thermoplastic elastomer layer; and (f) forming a surface texture structure on the upper surface of the thermoplastic elastomer meltblown layer.

2. The method for manufacturing breathable artificial leather as claimed in claim 1, wherein step (f) includes: (f1) Heating the thermoplastic elastomer meltblown layer to 140-180°C to soften the thermoplastic elastomer meltblown layer; and (f2) Forming the surface texture structure on the upper surface of the thermoplastic elastomer meltblown layer.

3. A method for manufacturing breathable artificial leather, comprising: (a) providing a thermoplastic elastomer meltblown layer; (b) impregnating and coloring the thermoplastic elastomer meltblown layer; (c) bonding the colored thermoplastic elastomer meltblown layer together with a thermoplastic elastomer layer having a plurality of air channels; (d) bonding a substrate layer to the lower surface of the thermoplastic elastomer layer; and (e) forming a surface texture structure on the upper surface of the thermoplastic elastomer meltblown layer.
