example 1

[0074] Polyethylene terephthalate as an island component and copolymer polyester as a sea component are subjected to composite spinning to form filaments, and the formed filaments are drawn, crimped, and cut to form first composite fibers , the form of the first composite fiber is a short fiber with a fineness of 3.5 denier and a length of 50 mm. The content of polyethylene terephthalate as the island component of the first composite fiber is 70% by weight, and the content of copolymer polyester as the sea component of the first composite fiber is 30% ( weight).

[0075] In addition, except that polytrimethylene terephthalate was used as the island component, a second composite fiber was prepared in the same manner as the first composite fiber in the form of a fineness of 4.0 denier and a length of 51mm staple fiber. The content of polytrimethylene terephthalate as an island component of the second conjugate fiber was 70% by weight, and the content of copolymer polyester as ...

example 2

[0081] Artificial leather was produced in the same manner as in Example 1 except that polybutylene terephthalate was used as the island component instead of polytrimethylene terephthalate to prepare the second conjugate fiber.

example 3

[0083] Artificial leather was produced in the same manner as in Example 1 except that a nonwoven fabric was produced such that the contents of the first conjugate fiber and the second conjugate fiber were 70% by weight and 30% by weight, respectively.

Abstract

Disclosed are artificial leather and a method for manufacturing same, wherein the artificial leather comprises two or more types of short fibers made of different components so as to achieve superior feel, flexibility, breathability, fullness, and significantly improved lightweight properties. The artificial leather of the present invention comprises: non-woven fabric including short fibers having a fineness of 0.001 to 0.5 denier; and a polymeric elastomer with which the non-woven fabric is impregnated, wherein the short fibers are two or more types of polyester-based short fibers having different numbers of repeating -CH2-units.

Description

technical field [0001] The invention relates to an artificial leather and a manufacturing method thereof. More particularly, the present invention relates to an artificial leather that can be used as a substitute for natural leather and a method for producing the same. Background technique [0002] Artificial leather is made by impregnating a polymer elastomer in a non-woven fabric containing three-dimensionally entangled microfibers. Due to its soft texture and unique appearance like natural leather, artificial leather is widely used in various occasions such as shoes, clothes , gloves, groceries, furniture and automotive interior materials. [0003] Such artificial leather is made using various fibers such as polyethylene terephthalate fibers and polyamide fibers. [0004] However, ordinary artificial leather is made of short fibers containing a single component. Therefore, the short fibers constituting the artificial leather exhibit similar mechanical physical properti...
