Production method of four-face elastic nylon fabric

Abstract

The invention discloses a production method of four-face elastic nylon fabric. The method comprises the following steps that nylon full-draft filament serves as warp after being subjected to warping,and nylon semi-draft filament and spandex fiber are twisted to serve as weft; the warp is sequentially subjected to warping, slashing, beaming and drafting and then fed to a textile machine fiber shaft; weft is subjected to high-elastic false twist processing to obtain high-elastic yarn; and technological parameters of a textile machine are set, and the high-elastic yarn is orthographic and solidified to form the four-face elastic nylon fabric. According to the method, by reasonably designing the fabric overall coverage coefficient, good fabric elasticity and the good cloth cover effect can beobtained.

Description

technical field [0001] The invention relates to the technical field of four-way elastic nylon fabric, in particular to a production method of four-way elastic nylon fabric. Background technique [0002] At present, textile products using nylon fibers as raw materials have been greatly promoted and utilized in sports, leisure and other clothing fabrics due to their superior properties such as wear resistance, but ordinary nylon fabrics still have some shortcomings in terms of elasticity. In order to improve this deficiency, wrap nylon fiber and spandex fiber, or compound nylon yarn with cross-linked polyene to improve its elasticity by adding a second yarn elastic fiber, which is used in women's underwear, trousers It is widely used in socks and swimwear. For example, in CN200780016018.9, the method of adding the second yarn cross-linked polyolefin and nylon is used, and in CN200910102325.X, the technical solution of nylon fiber, spandex fiber and polyester fiber is used to ...

Problems solved by technology

The method of compounding with other elastic fibers is not only expensive, but also considers the two components in the dyeing process, and the process needs to be selected. Especially in the case of compounding with spandex, it must be preheated at high temperature in the post-processing process. Moreover, the dyeing process will pollute other fibers such as PU, and the color fastness to washing of the fabric is poor, especially for color fading items.

Even if the items such as fading / cotton / nylon in the color fastness to washing of the fabric reach level 4 or above, they can only reach level 3 in the color fading item, and the general products even only have level 1 and level 2.
