Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of textile fabric, especially an anti-UV fabric with air permeability and cool feeling. BACKGROUND

[0002] Sun protection clothing is necessary equipment for consumers to do outdoor sports in summer. However, with the specialization of sports, the functional requirements of consumers for products are not limited to single anti-UV function, but more functions are required, such as cool feeling, antibacterial, air permeability, water repellency, moisture absorption, elasticity, etc. Among them, cool feeling and air permeability are the two most intense consumer demands in addition to anti-UV function.

[0003] At present, most anti-UV products are still achieved by coating polyurethane on the fabric, which makes the air permeability of the fabric almost zero. Some skin clothes currently achieve air permeability through the punching process, but it is difficult to finely control the size of the holes through laser punching or mechanical punching, so it is difficult to balance between anti-UV and air permeability. Some fabrics currently use soluble fibers in the warp and weft directions, such as alkali-soluble fibers, to make the fibers dissolve by using strong alkali during dyeing and finishing. However, due to the high content of alkali-soluble fibers, the fabric is prone to have a musty edge at the hole and has serious pilling. In addition, a large amount of strong alkali is required, which not only greatly affects the strength of the fabric itself, but also increases environmental pollution.

[0004] Therefore, the utility model provides an anti-UV fabric with less alkali and cool feeling, air permeability, and elasticity in view of the problems of the existing anti-UV fabric. SUMMARY

[0005] The utility model aims at providing an anti-UV fabric with air permeability and cool feeling to solve the problems of high content of alkali-soluble fibers in the prior art, environmental pollution, musty edge at the hole, and serious pilling.

[0006] In order to achieve the above purpose, the solution of the utility model is as follows:

[0007] An anti-UV fabric with air permeability and cool feeling is woven by warp yarn and weft yarn in a plain weave with one over one, wherein each cycle of the warp yarn contains 2-3 empty reeds, so that the fabric finally presents the phenomenon of empty warp yarn. The empty reed refers to that the yarn is not inserted into the reed as in the conventional weaving. The warp yarn includes inner layer yarn and outer layer yarn, the outer layer yarn is polyamide dull yarn, and the inner layer is spandex yarn. The weft yarn includes first weft yarn and second weft yarn, the first weft yarn is the same yarn as the warp yarn, and the second weft yarn is alkali-soluble yarn. In each cycle of the weft yarn, the yarn ratio of the first weft yarn to the second weft yarn is 15-18:1-2.

[0008] Further, the warp yarn and the empty reed cycle ratio is 15-18:2-3, and no more than 10 cycles per inch, the second weft yarn is 1-2 strips per cycle, and no more than 8 strips per inch.

[0009] Further, among the warp yarn and the first weft yarn, the outer layer is 20D-40D nylon luster yarn, and the yarn form is FDY, and the inner layer is 20D / 1-30D / 1 spandex yarn.

[0010] Further, the nylon luster yarn and the spandex yarn are wrapped together by machine wrapping, and the twist is 850-900 twists.

[0011] Further, the density of the warp yarn is 150T-180T, and the density of the weft yarn is 130T-160T.

[0012] After adopting the above structure, the breathable and cool anti-UV fabric of the utility model, 2-3 empty reeds are arranged in each cycle of the warp yarn, 1-2 alkali-soluble yarns are arranged in each cycle of the weft yarn, when the fabric passes through the alkali solution, the alkali-soluble yarn in the weft yarn is dissolved, thereby forming a hole at the node with the vertical blank formed by the empty reed in the warp direction, the alkali-soluble yarn accounts for no more than 10%, and the amount is small, so the amount of strong alkali is correspondingly reduced, environmental pollution caused by excessive use of strong alkali is avoided, and the hole edge and the serious fuzz are also avoided. And because the warp yarn and the first weft yarn both use nylon-covered spandex elastic yarn, when the fabric is dyed and finished, it will be further shrunk and contracted, so that the holes are more dense and small, further improving the anti-UV and cool effect of the fabric. Because the size of the hole is larger than the cross node gap of the warp yarn and the weft yarn itself, the air permeability of the fabric is further improved. The nylon luster yarn contains TiO2, which is beneficial to the improvement of anti-UV, so the fabric of the utility model can simultaneously have the functions of air permeability, coolness, elasticity and anti-UV.
