Problems solved by technology

Since only TiO with UV shielding effect is used 2 Micro particles, cannot effectively absorb ultraviolet rays in the UVA and UVB regions
[0005] According to related reports, TiO 2 , ZnO, SiO 2 、Al 2 o 3 , Fe 2 o 3 , CaCO 3 , PbO, kaolin, talcum powder, and clay particles themselves do not absorb ultraviolet rays, but only have reflective functions, which have low UV shielding efficiency

Abstract

The invention discloses an anti-ultraviolet functional fabric. The fabric contains polyester fibre with anti-ultraviolet nanoparticles; the anti-ultraviolet nanoparticle is one or more of TiO2, ZnO, CeO2, SiO2, Al2O3, Fe2O3, CaCO3, PbO, kaoline, talcum powder and argil nanoparticles; the nanoparticle accounts for 0.1 to 30 weight percent of the total weight of the fabric; the UPF value of the fabric is 50 plus; and T(UVA)AV is less than 5. The fabric can be used for manufacturing clothes, a cap, a sun shading article, a parasol, a tent, work clothes and various touring articles.

Description

Technical field: [0001] The invention relates to an ultraviolet-proof functional fabric. 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 UVB (280-315nm) with shorter wavelength and higher intensity, UVA (315-400nm) and UVC (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, an ideal protective textile should have high safety, low irritation, and more importantly, the function of resisting UVA and UVB at the same time. Analyzed from the mechanism, UV protective agents can be divided into UV absorbers and UV shielding agents. Among them, UV absorbers have a strong absorption function for ultraviolet rays in the UVA region and UVB region, and can ...
