Preparation method of anti-ultraviolet, anti-ageing and insect-prevention fiber

Abstract

The invention discloses a preparation method of an anti-ultraviolet, anti-ageing and insect-prevention fiber. The preparation of the anti-ultraviolet, anti-ageing and insect-repellent fiber is completed through preparation of a blended spinning solution, a spinning process and a post-treatment process. The preparation method of the anti-ultraviolet, anti-ageing and insect-prevention fiber adds lanthanide rare-earth metal organic complexes, the lanthanide rare-earth metal organic complexes have a good UV light conversion effect, can absorb 300 to 380nm ultraviolet light and convert ultravioletlight into infrared light, and the fiber prepared by blending the lanthanide rare-earth metal organic complexes and the solution spinning solution has good anti-UV and anti-yellowing functions. By adding permethrin and deltamethrin, the prepared fiber has a long-lasting pest control effect, and can be effectively applied to agricultural nets, pest control nets for animal husbandry, outdoor shadingproducts for zoos, outdoor working clothing and military uniform fields.

Description

technical field [0001] The invention belongs to the field of textile fiber preparation, and in particular relates to a method for preparing an anti-ultraviolet, anti-aging, anti-insect fiber. Background technique [0002] With the development of the modern industrial revolution, the ozone layer in the atmosphere is constantly being destroyed. The ozone layer is the best protective umbrella for the earth, it can absorb most of the ultraviolet rays from the sun. However, nearly two decades of scientific research and atmospheric observations have found that the ozone layer has been thinning, and an ozone hole has even been formed over the Antarctic. Generally, ultraviolet rays can be divided into short-wave (UVC: 200-290nm), medium-wave (UVB: 290-320nm) and long-wave (UVA: 320-400nm). The results of the study show that moderate exposure to ultraviolet rays is beneficial to human health, but excessive exposure to ultraviolet rays can cause some damage. Among them, when UVC pa...

Problems solved by technology

Textiles that have been placed outdoors for a long time also cause the internal molecular chain structure of the fiber to break, embrittle, and age due to ultraviolet radiation, which seriously affects the service life of outdoor products.

With the development and production of organic agriculture, a large number of insect-proof agricultural nets are increasingly used in agricultural planting. Such agricultural nets that have been placed in the wild for a long time have been aged by ultraviolet radiation, which seriously affects their service life.
