Problems solved by technology

For example, the patent document CN1303971A discloses a kind of anti-ultraviolet fabric, through padding mixed type anti-ultraviolet finishing agent, including reactive ultraviolet absorber and oil-soluble ultraviolet absorber, obtained SPF is more than 30 anti-ultraviolet fabric, but adopts dipping In the rolling processing method, the ultraviolet absorber can only be attached to the surface of the fiber. On the one hand, the amount of adhesion is limited, and the anti-ultraviolet effect is limited. On the other hand, the ultraviolet absorber attached to the surface is easy to fall off after washing, and the durability is poor.
Another example is the patent document CN105586773A which discloses a water-repellent and anti-ultraviolet textile. By impregnating an ultraviolet absorber, a diffusion accelerator and a fluorescent whitening agent, an anti-ultraviolet textile with an ultraviolet protection coefficient of more than 40 after 20 times of home washing is obtained. Although the anti-ultraviolet performance and durability of textiles have been improved to a certain extent, the addition of various finishing auxiliaries will change the color and shade of textiles, making the color difference of textiles larger

Embodiment 1

[0041] Select the polyester-cotton woven fabric that common PET content is 40% by weight, porosity 0.1%, put it in the dyeing machine, carry out in-bath processing in the finishing liquid that contains 0.3%o.w.f. benzotriazole ultraviolet absorber, The bath ratio is 1:20, and the product is obtained by incubating at 130°C for 30 minutes. The performance parameters of the obtained textiles are shown in Table 1.

Embodiment 2

[0043] The polyester-cotton woven fabric with a porosity of 0.1% is replaced with a polyester-cotton woven fabric with a porosity of 2.5%, and the rest are the same as in Example 1 to obtain the product. The performance parameters of the obtained textiles are shown in Table 1.

Embodiment 3

[0045] The polyester-cotton woven fabric with a porosity of 0.1% is replaced with a polyester-cotton woven fabric with a porosity of 2.6%, and the rest are the same as in Example 1 to obtain the product. The performance parameters of the obtained textiles are shown in Table 1.

Abstract

The invention discloses an anti-ultraviolet woven fabric. The anti-ultraviolet woven fabric contains 40wt%-100wt% of polyester fiber, the content of chlorine elements in organic compounds on the surface and inside of the polyester fiber is 50-120 ppm, and the organic compounds can absorb light with wavelength of 290-400 nm. The organic compound can not only adhere to the surface of the fiber, butalso can be introduced into the fiber, the content of anti-ultraviolet components in the fiber is increased, anti-ultraviolet washing durability is good, and the color difference of the woven fabric changes a little and the color light of the woven fabric is basically not affected.

Description

technical field [0001] The invention belongs to the field of textile post-finishing, and in particular relates to an anti-ultraviolet woven fabric with excellent washing durability obtained through a post-finishing method. Background technique [0002] With the development of society and the advancement of science and technology, frequent human activities, especially the extensive use of freon, have caused serious damage to the ozone layer in the earth's atmosphere, and the intensity of ultraviolet rays reaching the earth's surface has increased significantly. Excessive ultraviolet radiation has led to the onset of skin cancer The rate of pollution continues to increase, posing a huge threat to human health. For the health of the human body, in addition to sunscreens in the daily chemical industry, the development of functional textiles that can effectively prevent ultraviolet radiation has become an important issue in the textile industry. [0003] At present, there are th...
