Anti-ultraviolet woven fabric

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. 本发明公开了一种防紫外线机织物。该防紫外线机织物中聚酯纤维含量为40～100重量%，聚酯纤维表面及内部的有机化合物中，氯元素含量为50～120ppm，且有机化合物能够吸收波长290～400nm的光。这种有机化合物不但可以在纤维表面附着，甚至还能导入到纤维内部，提高了纤维中防紫外线成分的含量，抗紫外洗涤耐久性良好，同时机织物色差变化很小，基本不影响机织物的色光。
