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.

Embodiment 1

[0049] Firstly, carry out high-elastic false-twisting processing on nylon semi-drawn yarn 42dtex-10f-POY, wherein the draft ratio is 1.4 times, the temperature of the first hot box is 190°C, and the temperature of the second hot box is normal temperature, and the boiling water shrinkage is obtained. 30dtex-10f-nylon single-component elastic DTY yarn with 8% and CR value of 63%, and then use it as warp and weft yarn, using 2 / 2 twill, warp direction density 150 pieces / inch* weft density 130 pieces / inch for weaving to obtain a gray cloth, the ratio of the warp and weft coverage coefficients of the gray cloth is 1.15:1, and the overall coverage coefficient is 1533. The above-mentioned gray cloth is subjected to post-finishing processing, and the finished product is obtained through refining→dyeing→drying→stentering and setting→water-repellent laminating finishing→finishing and setting.

[0050] The post-finishing processing conditions are:

[0051] Refining (high temperature and...

Embodiment 2

[0060] The 30dtex-10f-nylon single-component elastic DTY yarn obtained in Example 1 is used as the warp yarn, and then the nylon full-drawn silk 70dtex-48f-FDY is subjected to high-elastic false twist processing, wherein the draft ratio is 1.02 times , the temperature of the first hot box is 150°C, the temperature of the second hot box is normal temperature, and the 68dtex-48f-nylon single-component elastic DTY yarn with a boiling water shrinkage rate of 5.5% and a CR value of 32% is prepared as a weft yarn Use, adopt plain weave, warp direction density 125 / inch*weft density 90 / inch to weave, make gray cloth, the overall coverage factor of gray cloth is 1400. The above-mentioned gray cloth is subjected to post-finishing processing, and the finished product is obtained through refining→dyeing→drying→water-repellent resin finishing→tentering→calendering→coating finishing→finishing and setting.

[0061] The post-finishing processing conditions are:

[0062] Water-repellent resin...

Embodiment 3

[0075] Firstly, high-elastic false-twisting processing is carried out on nylon fully drawn yarn 55dtex-48f-FDY, wherein the draft ratio is 1.1 times, the temperature of the first hot box is 170°C, and the temperature of the second hot box is normal temperature, and the boiling water shrinkage is obtained 48dtex-48f-nylon single-component elastic DTY yarn with 7% and CR value of 48%. Then use it as warp and weft yarn, adopt 3*2 warp heavy flat weave, warp direction density 120 / inch*weft density 105 / inch to weave, make gray cloth, gray cloth warp and weft direction coverage factor ratio is 1.14: 1, The overall coverage factor is 1600. After finishing the above gray cloth, the finished product is obtained through refining→dyeing→drying→stenter setting→water-repellent laminating finishing→finishing and setting.

[0076] The post-finishing processing conditions are:

[0077] Refining (high temperature and heat treatment): temperature 95°C, speed 100m / min, residence time 5-10s

Abstract

The invention discloses a nylon four-sided elastic fabric and a preparation method thereof. The warp and weft directions of the fabric adopt high-elastic nylon yarns, and the elastic elongation rate in the warp direction is 15-25%, and the elastic elongation rate in the weft direction is 15-35%. , the elastic recovery rate in the warp and weft direction is above 90%, the coverage factor is 1200-3000, and the color fastness to washing is above grade 4; when the warp and weft yarns are of the same denier, the warp and weft direction coverage factor ratio is 0.6-1.5:1; The invented fabric has the characteristics of excellent elasticity, high color fastness and simple processing technology, and is especially suitable for the production of sports and leisure clothing.

Description

technical field [0001] The invention relates to a textile, in particular to a four-sided elastic nylon fabric and a production method thereof. 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 achieve the elasticity of the ...
