Anti-ultraviolet fiber, fiber filtering net and preparation method and application of anti-ultraviolet fiber

Abstract

The invention discloses an anti-ultraviolet fiber. The anti-ultraviolet fiber contains the following components in parts by weight: 0-4 parts of an anti-ultraviolet slice and 96-100 parts of PET, or 1-3 parts of the anti-ultraviolet slice and 97-99 parts of PET or 2 parts of an anti-ultraviolet slice and 98 parts of PET, wherein PET is polyethylene glycol terephthalate, and the chemical formula ofPET is COC6H4COOCH2CH2O. The anti-ultraviolet fiber is prepared by the steps of adequately mixing the raw materials, drying, putting the mixture into a spiral extruder, carrying out melt blending extrusion, granulating so as to obtain an anti-ultraviolet fiber master batch, and carrying out spinning, winding and stretching so as to obtain the anti-ultraviolet fiber. The anti-ultraviolet fiber isparticularly applicable to the field of deep sea fishing, capable of resisting ultraviolet rays, applicable to deep sea environments, strong in corrosion resistance or alkali resistance, high in breaking strength, soft in line and applicable to the preparation of deep sea fishing tools.

Description

technical field [0001] The invention belongs to the field of fiber materials and marine fishing materials and fishing gear, and in particular relates to an anti-ultraviolet fiber, a filter net containing the fiber, a preparation method and application of the fiber and the filter net. Background technique [0002] Generally speaking, appropriate ultraviolet rays are beneficial. It can promote the synthesis of vitamin D, inhibit rickets, and have disinfection and sterilization effects. However, in recent years, due to the large amount of chlorofluorocarbons such as Freon and other chlorofluorocarbons discharged by human production and life, the earth's protective umbrella, that is, the atmosphere, has been increasingly damaged. The protective circle of the earth, that is, the ozone layer becomes thinner and thinner, and the amount of ultraviolet radiation reaching the ground increases. The diseases caused by excessive ultraviolet radiation are increasing, and the damage caused...

AI Technical Summary

Problems solved by technology

Natural fibers such as cotton and silk have low UV absorption ability, so they have poor UV protection performance.

[0003] At present, in the deep-sea special fishing industry, only synthetic fibers with low breaking strength are generally considered.

However, it has not been considered that since marine fishing is generally exposed to the sun for a long time without shelter, in the current situation where ultraviolet rays are more and more harmful, if traditional fishing gear fiber nets are used, it will cause aging and deformation of fishing gear Acceleration is getting faster and the breaking strength is getting higher, so the service life of fishing gear is seriously shortened
