Preparation method of photocatalyst regenerated cellulose fibers

Abstract

The invention provides a preparation method of photocatalyst regenerated cellulose fibers. The preparation method comprises preparation of a photocatalyst emulsion, preparation of cellulose spinning viscose and preparation of a photocatalyst blending and spinning solution. The prepared photocatalyst regenerated cellulose fibers have a remarkable decomposition function on aldehyde, benzene, benzene compounds and amide and have a function of air pollutant purification, and the photocatalysis removal rate is 30%-60%; the photocatalysis removal rate is 30%-60% after ten times of washing; the dry breaking strength of the prepared cellulosic fibers is 2.15-2.38 cN / dtex, the wet breaking strength is 1.15-1.35 cN / dtex, the photocatalyst regenerated cellulose fibers have excellent physical and mechanical properties, textile processing performance and wearability, further keep characteristics of wet absorption breathability of conventional viscose and comfort in wearing and also have the advantages of high photocatalyst oxygenolysis of VOCs (volatile organic compounds) and function durability.

Description

technical field [0001] The invention relates to a preparation method of functional cellulose fibers, in particular to a preparation method of regenerated cellulose fibers with photocatalyst function, and belongs to the field of fiber technology. Background technique [0002] In recent years, a large number of new building materials, decoration and decoration materials have entered people's life and production. Volatile organic compounds (VOCs) such as aldehydes, benzene, benzene series, sulfides, and ammonia compounds have also become the main substances of indoor air pollution. It is a great threat to the healthy life of human beings. These harmful substances can cause damage to human skin, respiratory tract and internal organs, reduce human immunity, and long-term exposure can cause cancer and even cause gene mutations. If these harmful substances are not removed in time, it will have an extremely adverse impact on people's health. Therefore, the development of safe and e...

AI Technical Summary

Problems solved by technology

[0006] (1) Photocatalyst materials have poor stability on fabrics, are easy to fall off or wear and are not resistant to washing, have poor functional durability, and will affect the wearability of textiles;

[0007] (2) Good physical and mechanical properties, textile processing performance and wearing performance cannot be taken into account; conventional viscose fibers have good moisture absorption and breathability, and are comfortable to wear; photocatalysts have strong ability to oxidize and decompose volatile organic compounds (VOC), and good functional durability. specialty
