Abstract

The invention discloses a production method of uvioresistant fiber. The production method includes the steps of preparing uvioresistant master-batches; mixing and drying uvioresistant compound additive and carrier resin, melting the mixture in a screw extruder for extrusion and pelletizing to obtain the uvioresistant master-batches; producing the uvioresistant fiber; and slicing and blending the uvioresistant master-batches and the fiber, and performing spinning, winding and drafting to obtain the uvioresistant fiber. The uvioresistant compound additive comprises, by weight, 30-40 parts of titanium dioxide, 20-25 parts of aluminum oxide, 3-5 parts of zeolite, 15-20 parts of 2-hydroxy-4-methoxybenzophenone, 10-15 parts of 4-t-butylphenyl salicylate, and 1-5 parts of sodium polyacrylate dispersant. The uvioresistant fiber is high in ultraviolet resistance, highly durable, nontoxic and safe.

Description

technical field [0001] The invention relates to a production method of an anti-ultraviolet fiber. Background technique [0002] Generally speaking, appropriate ultraviolet rays are beneficial to the human body. 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, and more and more diseases are caused by excessive ultraviolet radiation. Under normal circumstances, the safe radiation amount of ultraviolet rays that human skin can accept should be within 20kJ / m2 per day, while the radiation amount of ultraviolet rays reac...
