Problems solved by technology

Wearing white clothes in summer has the advantage of being cool and not absorbing heat. However, at present, there are few actual researches on the anti-ultraviolet finishing of white fabrics. On the one hand, white fabrics are prone to yellowing due to the influence of temperature or additives in pre-treatment and post-finishing processes, which greatly affects the aesthetics of clothing
These problems limit the use of white anti-ultraviolet fabrics

Embodiment 1

[0030] The production technology of white nylon anti-ultraviolet fabric comprises the following steps:

[0031] Step S1: Weaving. The warp and weft yarns are all made of 40D nylon core-spun yarn and 20D spandex core-spun yarn, which is made of four-way stretch fabric, and the number of warp and weft yarns is above 320T;

[0032] Step S2: washing the gray cloth with water. Using the open-width washing process, the gray cloth is preliminarily washed to release the tension of the gray cloth, and the desizing and refining aids are applied. The desizing and refining aids used include urea, linear alkylbenzene sulfonate, and AEO detergent;

[0033] Step S3: Cold pile treatment. The gray cloth is rolled and stacked for 24 hours;

[0034] Step S4: washing and shrinking. Wash the gray fabric after cold stacking in a tank, the bath ratio of washing and pre-shrinking is 1:10, add 5g / L caustic soda and 2g / L deoiling spirit to remove the oil agent and slurry on the fabric, and further ...

Embodiment 2

[0041] The production technology of white nylon anti-ultraviolet fabric comprises the following steps:

[0042] Step S1: Weaving. The warp and weft yarns are all made of 20D nylon core-spun yarn and 20D spandex core-spun yarn, which is made of four-way stretch fabric, and the number of warp and weft yarns is above 420T;

[0043] Step S2: washing the gray cloth with water. Using the open-width washing process, the gray cloth is preliminarily washed to release the tension of the gray cloth, and the desizing and refining aids are applied. The desizing and refining aids used include urea, linear alkylbenzene sulfonate, and AEO detergent;

[0044] Step S3: Cold pile treatment. The gray cloth is rolled and stacked for 18 hours;

[0045] Step S4: washing and shrinking. Wash the gray fabric after cold stacking in a tank, the bath ratio of washing and pre-shrinking is 1:12, add 3g / L caustic soda and 1g / L deoiling spirit, remove the oil agent and slurry on the fabric, and further el...

Embodiment 3

[0052] The production technology of white nylon anti-ultraviolet fabric comprises the following steps:

[0053] Step S1: Weaving. The warp and weft yarns are all made of 40D nylon core-spun yarn and 20D spandex core-spun yarn, which is made of four-way stretch fabric, and the number of warp and weft yarns is above 320T;

[0054] Step S2: washing the gray cloth with water. Using the open-width washing process, the gray cloth is preliminarily washed to release the tension of the gray cloth, and the desizing and refining aids are applied. The desizing and refining aids used include urea, linear alkylbenzene sulfonate, and AEO detergent;

[0055] Step S3: Cold pile treatment. The gray cloth is rolled and stacked for 21 hours;

[0056] Step S4: washing and shrinking. Wash the gray fabric after cold stacking in a tank, the bath ratio of washing and pre-shrinking is 1:11, add 4g / L caustic soda and 1.5g / L deoiling spirit, remove the oil agent and slurry on the fabric, and further ...

Abstract

The invention relates to the field of textile production, in particular to a production process of white nylon ultraviolet-resistant fabric. The production process of the white nylon ultraviolet-resistant fabric comprises the steps of weaving cloth, washing gray fabric with water, performing cold heap treatment, water-washing and pre-shrinking, presetting, putting into a jar and practicing cloth,performing ultraviolet-resistant water washing, shaping finished products as well as performing steam pre-shrinking. By the process provided by the invention, oil and impurities on the fabric can be removed deeply; furthermore, the internal stress of the gray fabric is released maximally, the fabric is continuously tightened and the porosity is reduced while the fabric is subjected to impurity removal, so that the best ultraviolet shielding effect is achieved; meanwhile, the fabric has high size stability, avoids wrinkle deformation in the use process, has high elasticity and is comfortable towear. According to the process, yellowing of the fabric in the technology process is avoided by controlling the aspects of treatment mode, treatment temperature and aid use.

Description

technical field [0001] The invention relates to the field of textile production, in particular to a production process of a white nylon anti-ultraviolet fabric. Background technique [0002] In recent years, thin outdoor sun protection clothing has gradually become popular in the market. It can help human skin resist ultraviolet radiation, reduce the probability of skin cancer, and protect human health. At the same time, it can also be worn indoors to resist the coolness of air-conditioned rooms. For the requirements of thin sun protection clothing, on the one hand, it must meet the national anti-ultraviolet standard and have a good anti-ultraviolet effect; [0003] The UV transmittance depends on many factors, such as tissue structure, coverage factor, color, chemical additives in the process and sample treatment, etc. The denser the woven or knitted fabric, the smaller the amount of ultraviolet rays passed, that is, the smaller the fabric porosity, the better it can block...
