Description

TECHNICAL FIELD

[0001] The present invention relates to an artificial leather and a method for manufacturing the same. More specifically, the present invention relates to an artificial leather useful as an alternative to natural leather and a method for manufacturing the same.BACKGROUND ART

[0002] An artificial leather is manufactured by impregnating a polymeric elastomer in a non-woven fabric comprising three-dimensionally entangled ultrafine fibers, which is widely utilized in a variety of applications such as shoes, clothes, gloves, miscellaneous goods, furniture and automobile interior materials due to natural leather-like soft texture and unique appearance.

[0003] Such an artificial leather is manufactured using a variety of fibers such as polyethylene terephthalate fibers and polyamide fibers.

[0004] However, a common artificial leather is made of short fibers containing a single component. Accordingly, the short fibers constituting the artificial leather exhibit similar mechanical ph...
