Embodiment 1

[0014] Add TiO2 and CeO2 particles into the polyester by blending to prepare anti-ultraviolet polyester chips. The amount of anti-ultraviolet particles in the chips is 27% of the total weight of the anti-ultraviolet polyester chips, and the particle size of the anti-ultraviolet particles is 100nm. The anti-ultraviolet polyester chips are dried and then spun at a drying temperature of 130°C. The amount (weight) ratio of TiO2 and CeO2 particles is 50%:50%.

[0015] Spinning: Put the anti-ultraviolet polyester chips into the spinning equipment, pass through the screw extruder, the temperature of each zone of the extruder is between 280-295 ℃, make it into a molten state, flow to the metering pump, and press it after metering Into the assembly, and finally through the spinneret, the filaments are cooled by side blowing, and taken up and formed at a spinning speed of 2500-4000m / min. The obtained pre-drawn yarn has a strength ≥ 2.2cN / dtex and an elongation of 150-200%.

Abstract

The invention discloses an anti-ultraviolet polyester fiber. The anti-ultraviolet polyester fiber is formed by mixing anti-ultraviolet nanoparticles and polyester chips according to the weight percentage, wherein the content of the anti-ultraviolet nanoparticles is 0.5wt%-35wt% and the fineness of the fiber is 0.7dtex -10dtex. As containing the anti-ultraviolet nanoparticles, the polyester fiber has double functions of absorbing or reflecting ultraviolet rays, so that the ultraviolet ray shielding effect is high while the common performance of the polyester fiber is not influenced.

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 ...
