Problems solved by technology

Ultra-thin and light-weight clothing in summer must pay attention to the research and development of anti-ultraviolet fibers and their fabrics. Long-term exposure to ultraviolet rays is likely to cause skin cancer and affect human health.
However, for ultra-thin and lightweight clothing in summer, the anti-ultraviolet functional particles added are limited, and the addition of functional particles will affect its spinnability, and the thin light of the clothes penetrates directly into the skin, often resulting in insufficient absorption of ultraviolet rays and the effect of sun protection. not good

Abstract

The invention relates to an uvioresistant nylon-6 fiber for an ultrathin and light fabric and a preparation method of the uvioresistant nylon-6 fiber. The uvioresistant nylon-6 fiber is formed by branched-chain nylon-6 functional master batches and conventional nylon-6 chips through blending and spinning, wherein the branched-chain nylon-6 functional master batches account for 6-10% in weight percentage; the preparation method comprises the steps of firstly, preparing the branched-chain nylon-6 functional master batches through in-situ polymerization or blending; secondly, crystallizing and drying the branched-chain nylon-6 functional master batches and the conventional nylon-6 chips respectively and mixing, and then performing vacuum drying to obtain blended chips; and finally, performing melt spinning to the blended chips with melt spinning equipment. The using amount of ultraviolet absorbents is reduced, the fiber spinnability is improved, the uvioresistant and the ultraviolet aging resistant effects are ensured; the fabric can strongly absorbing ultraviolet radiation while light weight is ensured, and is suitable for developing thin and light clothes in summer.

Description

technical field [0001] The invention belongs to the field of functional nylon 6 fibers, in particular to an anti-ultraviolet nylon 6 fiber for ultra-thin and lightweight fabrics and a preparation method thereof. Background technique [0002] China's nylon industry started in the mid-1950s and is one of the earliest chemical fiber varieties. It has a series of excellent elasticity, wear resistance, corrosion resistance and other characteristics, and plays an irreplaceable role in the field of industrial and engineering plastics. Nylon fiber (also known as polyamide fiber or nylon fiber) has many varieties. At present, nylon 6 fiber and nylon 66 fiber are still the most widely used in industrial production and application. Compared with foreign developed countries, there are very few new nylon fiber products with independent intellectual property rights in my country at present, and fewer varieties are actually used for industrialization. Secondly, the price of nylon fiber is ...
