Abstract

The invention discloses ultraviolet resistant polyester fiber; the polyester fiber contains ultraviolet resistant nano particles; the content of the ultraviolet resistant nano particles is 0.1 weight percent to 30 weight percent, and the size of the fiber is 0.7dtex to 10dtex. The production method comprises the following steps: the ultraviolet resistant nano particles are extruded, blended or co-polymerized and added into polyester to prepare ultraviolet resistant polyester slices; and then the polyester slices are spun and wound to obtain as-formed fiber; the as-formed fiber is falsely twisted or stretched to obtain DTY or FDY. The fabric developed with the fiber is good to touch, has good fabric properties and dyeing properties, can be used to manufacture ready-to-wear clothes, hats, sunshade products, sun umbrellas, tents, work clothes and all tourist products. The process is simple and easy to be operated.

Description

Technical field: [0001] The invention relates to an anti-ultraviolet polyester fiber. Background technique: [0002] The sunlight that reaches the earth's surface consists of ultraviolet rays (5%), visible light (50%), and infrared rays (45%). Ultraviolet rays are composed of UV-B (280-315nm) with shorter wavelength and higher intensity, UV-A (315-400nm) and UV-C (200-280nm) with longer wavelength and lower intensity. The literature of scientific and clinical trials shows that the skin damage caused by UVB is immediate and severe, while the skin damage caused by UVA is long-term and chronic. Therefore, ideal protective products should be safe, less irritating, and more importantly, have the function of resisting UVA and UVB at the same time. Analyzed from the mechanism, it is divided into ultraviolet absorbers and ultraviolet shielding agents. Absorbers have strong absorption properties for ultraviolet rays in the UVB region and UVA region, can reduce or completely absorb ...
