Problems solved by technology

[0005] The technical problem mainly solved by the present invention: aiming at the current chemical fiber textiles with low comfort after wearing, no sweat absorption and poor air permeability, while the chemical composition of viscose fiber is the same as that of cotton fiber, and has good biocompatibility and hygroscopicity, but Also therefore the surface often adheres to a large number of microorganisms such as bacteria, fungi and other organisms, and the defect of easily breeding bacteria provides a kind of method utilizing water lily to prepare antibacterial viscose fiber. The total flavonoids of lotus seeds are used as antibacterial agents, and water lily stems are used as natural cellulose sources. After alkalization, aging, sulfonation and other processes, cellulose sulfonate is made, and then dissolved in dilute alkali solution and supplemented with flavonoid antibacterial agents by spinning After that, antibacterial viscose fiber is obtained, which has the comfort of cotton fiber and antibacterial ability, which not only solves the defects of low wearing comfort, no sweat absorption and warmth retention of chemical fiber textiles, but also solves the problems that the surface of ordinary viscose fiber often suffers from. Adhering to a large number of microorganisms such as bacteria, fungi and other organisms, it is easy to breed bacteria, and the production process is green and environmentally friendly, the source of raw materials is abundant, the cost is low, and it has excellent application prospects

Abstract

The invention relates to a method for preparing antibacterial viscose fibers by comprehensively utilizing water lilies, and belongs to the field of viscose fiber preparation. The method comprises the steps that lotus plumule of the water lilies is taken as a material, lotus plumule total flavonoid is extracted through assistance of an enzymic method to serve as an antibacterial agent, water lily stems serve as a natural cellulose source to be prepared into cellulose sulphonate through the processes of alkalifying, aging, sulfonating and the like, the cellulose sulphonate is dissolved into a dilute alkali solution, a flavonoid antibacterial agent is added for assistance, spinning is performed, and then the antibacterial viscose fibers are obtained. According to the method, the antibacterial capacity is achieved while the antibacterial viscose fibers have the comfortableness of cotton fiber, the problems that chemical fiber textiles are low in wearing comfort degree and cannot absorb sweet and keep warm are solved, and the problems that a large number of microorganisms such as bacteria, fungi and other organisms are often stuck to the surfaces of ordinary viscose fibers, and the bacteria are easy to breed are solved; in addition, the production technology is green and environmentally friendly, the raw materials are rich in source, the cost is low, and the excellent application prospect is achieved.

Description

technical field [0001] The invention relates to a method for comprehensively utilizing water lilies to prepare antibacterial viscose fibers, which belongs to the field of viscose fiber preparation. Background technique [0002] Viscose fiber refers to cellulose extracted from cellulose raw materials such as cotton linters, wood and plant straw, processed into spinning stock solution, and then artificial fiber made by wet spinning. The chemical composition of viscose fiber is the same as that of cotton fiber, the degree of polymerization and crystallinity are lower than that of cotton fiber, the degree of orientation is lower, and the structure is looser. Therefore, viscose fiber has better adsorption performance, excellent adsorption, dyeing and color fastness, but ordinary viscose fiber has lower wet strength than cotton, poor elastic recovery, and the fabric is easy to deform and wrinkle. Similar to most natural fibers, viscose fibers have good biocompatibility and hygros...
