Problems solved by technology

Traditional synthetic leather uses cotton or polyester / cotton yarn as the base fabric. This kind of synthetic leather has good dimensional stability and strong air permeability, but its elasticity is poor, and its flatness, uniformity and surface style are not ideal.
At present, this kind of synthetic leather can only be used as a medium and low-grade product, but it cannot be used as a high-grade synthetic leather.

Embodiment Construction

[0016] Concrete processing technology of the present invention is as follows:

[0017] A. fiber mixing: polyamide fiber and polyester fiber are mixed into composite fiber, and its proportioning by weight is:

[0018] Polyamide fiber 35-45 polyester fiber 55-65;

[0019] B. Weaving: Weaving double-layer fabrics with composite fibers (A type of warp knitted fabric formed by connecting two layers of single-sided weaves with connecting yarns is called a double-layer fabric. The layer fabric has warp yarns of two systems, the surface warp and the inside warp, which can be connected with the surface weft and the inside warp in a variety of structural ways. The weft yarns of the two weft systems are interwoven, such as connecting yarns on both sides of the two-layer single-jersey fabric to form a tubular warp-knitted fabric; Multi-thread stable connection between two layers of single-jersey weave. Both sides of warp-knitted double-layer fabrics expose the front loop backbone, a...

Abstract

The invention discloses polyamide fiber and polyester fiber composite synthetic leather which comprises the following components in weight part: 35-45 parts of polyamide fiber and 55-65 parts of polyester fiber. The processing technology comprises the following steps: A, fiber mixing; B, weaving; C, alkali treatment; D, dyeing; E, padding, preliminary drying and baking; F, softening finishing; G, gigging; H, shape setting of finished products. The polyamide fiber and polyester fiber composite synthetic leather has the advantages that the ultra high water absorption of superfine fiber is achieved, so that the superfine PU synthetic leather has the moisture absorption characteristic of natural leather made of bunchy superfine collagen fiber, further the appearance quality, physical property, wearing comfort for people and the like of the synthetic leather can be comparable with that of advanced natural leather.

Description

technical field [0001] The invention relates to the field of textile synthetic leather. Background technique [0002] . Traditional synthetic leather uses cotton or polyester / cotton yarn as the base fabric. This kind of synthetic leather has good dimensional stability and strong air permeability, but its elasticity is poor, and its flatness, uniformity and surface style are not ideal. At present, this kind of synthetic leather can only be used as a medium and low-grade product, but it cannot be used as a high-grade synthetic leather. Contents of the invention [0003] The object of the present invention is exactly to provide a kind of composite synthetic leather of polyamide fiber and polyester fiber and processing technology for the above-mentioned deficiency of traditional synthetic leather. [0004] Polyamide fiber and polyester fiber compound synthetic leather, it is made up of polyamide fiber and polyester fiber; Its proportion by weight is: [0005] Polyamide fibe...
