Abstract

A uvioresistant short fiber manufacturing method mainly includes that corn starch and polyesters are used as basic materials, and nano titanium dioxide is added to serve as a uvioresistant agent to make short fibers by melt spinning. The short fibers manufactured according to the method integrate advantages of corn fibers and polyester fibers and are excellent in uvioresistant effect.

Description

[0001] technical field [0002] The invention relates to the field of anti-ultraviolet fiber weaving, in particular to a method for manufacturing an anti-ultraviolet short fiber. [0003] Background technique [0004] The rapid development of the world's economy today has also brought about serious problems such as environmental pollution, especially the increasingly serious damage to the ozone layer. The intensity of ultraviolet rays reaching the ground has increased significantly, and the damage of ultraviolet rays to the human body has also increased. Long-term exposure to ultraviolet rays will cause Reduce the lifespan of organic molecules and reduce the immune function of the human body, which not only damages the skin and causes dermatitis, freckles, erythema and other diseases, but also promotes eye diseases, cataracts, and even skin cancer and other diseases. Therefore, how to solve the damage of ultraviolet rays has become an urgent problem to be solved. question. ...
