Problems solved by technology

Especially in recent years, the environment has deteriorated, the atmospheric ozone layer has been seriously damaged, and the ozone layer is thin or even empty, which leads to an increase in the ultraviolet content directly radiated to the ground, which increases the damage to the human body.
Ultraviolet rays are divided into near ultraviolet rays (UVA), mid-wavelength ultraviolet rays (UVB), far ultraviolet rays (UVC) and vacuum ultraviolet rays (UVD). UVA can penetrate the skin and cause melanin precipitation. Long-term exposure can destroy elastic fibers and collagen fibers, making the skin Wrinkle aging loses elasticity, which is the component with the highest ultraviolet content; UVB penetrating ability is not as good as UVA, basically absorbed by the ozone layer of the atmosphere, and the content reaching the ground is relatively small, but in recent years, due to the destruction of the ozone layer, UVB can penetrate the atmosphere to reach the surface , due

Abstract

The invention provides a preparation method of an ultrathin woven fabric with anti-ultraviolet-photocatalysis, antibacterial and water-proof functions. The preparation method comprises the steps of weaving, setting, finishing and dyeing and forming, wherein in the step of weaving, the fibrous raw materials comprise anti-ultraviolet and antibacterial polyester or polyamide. The product prepared byusing the method has excellent functional effects in the anti-ultraviolet, antibacterial and water-proof aspects, wherein in the anti-ultraviolet aspect, the ultraviolet protection factor (UPF) valuecan reach 100, the ultrathin woven fabric can reach the highest anti-ultraviolet standard UPF value 50+, and compared with products prepared by using other methods, the gain is about 100%; according to the antibacterial effect, the sterilizing rate under photocatalysis (sun light) reaches 99%, and meanwhile, it can be stably ensured that the water-proof grade of the fabric reaches four.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to a method for preparing an ultra-thin woven fabric with anti-ultraviolet photocatalysis, antibacterial and waterproof functions. Background technique [0002] With the improvement of people's quality of life, the demand for clothing functionality has gradually increased. Especially in recent years, the environment has deteriorated, the atmospheric ozone layer has been severely damaged, and the ozone layer is thin or even empty, which leads to an increase in the ultraviolet content directly radiated to the ground, which increases the damage to the human body. Ultraviolet rays are divided into near ultraviolet rays (UVA), mid-wavelength ultraviolet rays (UVB), far ultraviolet rays (UVC) and vacuum ultraviolet rays (UVD). UVA can penetrate the skin and cause melanin precipitation. Long-term exposure can destroy elastic fibers and collagen fibers, making the skin Wrinkle aging loses...
