AI Technical Summary

Problems solved by technology

Long-term ultraviolet radiation causes fabric aging, easy yellowing, reduced strength, and shortened its service life
The dye or brightener on the fabric has a certain filtering effect on ultraviolet rays, but its effect will be greatly weakened after repeated washing and wearing. For fabrics used in tropical areas or in summer, the ultraviolet protection effect played is not enough

Abstract

The invention discloses an anti-ultraviolet and antibacterial fiber and a preparation method thereof, and belongs to the technical field of medical new materials. The fiber comprises the following raw materials of polyamide 6 and polyamide master batch; the polyamide master batch is obtained by uniform mixing of dried polyamide 6 and an anti-ultraviolet agent, stirring and mixing by a high-speed mixer, and extruding and granulating by a double-screw extruder; and the used anti-ultraviolet agent is TiO2 and / or TiO2 / Ag composite nanoparticles modified by a surface modifier, and the used surface modifier is obtained by carrying out a reaction on 5,5-diphenyl hydantoin and chlorosilane. The preparation method of the fiber comprises the following steps of drying the polyamide 6 and the polyamide master batch; and melting the polyamide 6 and the polyamide master batch by using the double-screw extruder, performing spinning by using a spinneret plate, and performing winding and drafting to obtain the anti-ultraviolet and antibacterial fiber. The anti-ultraviolet and antibacterial fiber has good anti-ultraviolet property, antibacterial property and yellowing resistance.

Description

technical field [0001] The invention belongs to the technical field of new fiber materials, and in particular relates to an anti-ultraviolet and antibacterial fiber and a preparation method thereof. Background technique [0002] Sunlight and artificial light sources contain invisible ultraviolet rays. Ultraviolet rays are an electromagnetic wave with a wavelength between X-rays and visible light waves. Generally, they can be divided into three types: UVA, UVB, and UVC according to the wavelength. The shorter the wavelength of ultraviolet rays, the higher the energy. Big. Ozone that exists more than 10km above the ground is the "protective umbrella" of the earth. It can absorb a large amount of ultraviolet rays that are harmful to humans and plants in solar radiation, especially UVC is mostly absorbed by ozone. Therefore, the harm of ultraviolet rays is generally caused by the combined effect of UVB and UVA. Long-term ultraviolet radiation causes human skin pigmentation, er...
