Artificial leather and method for manufacturing the same

Abstract

Disclosed are an artificial leather that comprises two or more types of short fibers made of different components and thus exhibits superior texture, flexibility, breathability and fullness and enables great weight reduction, and a method for manufacturing the same.The artificial leather includes a non-woven fabric having a fineness of 0.001 to 0.5 denier, and a polymeric elastomer impregnated in the non-woven fabric, wherein the short fibers are two or more types of polyester short fibers having different numbers of repeat units of —CH2—.

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...

AI Technical Summary

Benefits of technology

The present invention relates to an artificial leather that exhibits superior flexibility, breathability, and fullness while reducing weight. The artificial leather comprises two or more types of polyester short fibers having different elastic recovery, which form a spring-like structure during an entanglement process. It also has pores that exhibit superior compressive elasticity and are uniformly formed to have a predetermined size. Furthermore, the spring structure makes surface naps upright, reducing displeasure caused by the difference in friction property according to the nap direction. The non-woven fabric used in the invention exhibits superior adhesiveness to polyurethane and is widely utilized in various fields such as shoes, clothes, gloves, miscellaneous goods, furniture and vehicle internal materials.

Problems solved by technology

Also, there is a problem of difficulty of realization of an artificial leather having satisfactory texture, fullness and flexibility due to differentiation in terms of interaction between short fibers.

However, these methods may deteriorate other properties of an artificial leather such as texture or appearance.
