Embodiment 1

[0052] On the 28G double-sided circular knitting machine, yarn 1 is used for the inner and outer yarns, which is 75D-72f-full-dull PET DTY. The length of the surface yarn is 255mm, and the length of the inner yarn is 290mm. figure 1 The tissue is weaved, then pre-treated and dyed white (1g / l refining agent, 130°C*30min with disperse white dye), post-finishing (1g / l antistatic agent, 1g / l neutralizing acid), and after dyeing Compared with the setting, the horizontal density is reduced by 12%, and the vertical density is reduced by 17%, wherein the TiO in the yarn 2 The content is 2.4%, and the knitted fabric of the present invention whose middle layer average height is 62um is obtained.

[0053] The properties of the obtained fabric are shown in Table 1.

Embodiment 2

[0055] In the finishing process, compared with after dyeing, the transverse density decreases by 14%, and the longitudinal density decreases by 20%, and all the other are the same as in Example 1, and the knitted fabric of the present invention whose middle layer average height is 62um is obtained.

[0056] The properties of the obtained fabric are shown in Table 1.

Embodiment 3

[0058] When weaving, the line length of the inner yarn is lengthened by 0.35%, and all the other are the same as embodiment 2 to make the knitted fabric of the present invention whose middle layer average height is 135um.

[0059] The properties of the obtained fabric are shown in Table 1.

Abstract

The invention discloses a highly-breathable anti-ultraviolet knitted fabric and application thereof. The knitted fabric comprises a surface layer, a middle layer and a lining layer; an occupied proportion of direct mesh openings on the surface layer of the knitted fabric is 5% to 15%; and an average height of the middle layer of the knitted fabric is 60 mum to 200 mum. The knitted fabric disclosedby the invention has excellent breathability and ultraviolet resistance, and garments made of the knitted fabric are very suitable to wear outdoors in spring and summer.

Description

technical field [0001] The invention relates to a knitted fabric and its application, in particular to a knitted fabric with high air permeability and good continuous anti-ultraviolet effect and its application. Background technique [0002] In the hot summer, people put forward more and more functional requirements for sweatshirts, T-shirts, POLO shirts, etc. worn next to the body. As we all know, the weather in summer is very sultry, and the amount of ultraviolet radiation is large. Excessive exposure will damage the skin and even destroy the immune system. At the same time, due to sweating, it is easy to cause physical discomfort. Good UV resistance and good breathability. [0003] In terms of tissue design, there is a mutual restrictive relationship between air permeability and UV resistance. Most of the fabrics with good air permeability have weak anti-ultraviolet performance. This is because most of the fabrics with good air permeability have low density and many por...
