Problems solved by technology

This method is to make pulp from wormwood stalks and use the conventional viscose production process to make fibers. It mainly utilizes the A-type cellulose of the wormwood stalks. Low, short fibers, low utilization rate for the production of viscose fibers, and less use of antibacterial ingredients in wormwood
This preparation process is cumbersome and costly, and the black liquor produced in the pulp preparation process has a high organic content, and the cost of treating waste liquor is very high

Abstract

The invention provides a preparation method of antibacterial artemisia argyi viscose fibers. The preparation method comprises following steps: (1), preparation of an artemisia argyi extracting liquid: artemisia argyi is cooked in water, cooking liquor obtained after cooking is filtered, and the artemisia argyi extracting solution is obtained; (2), preparation of the antibacterial fibers: the artemisia argyi extracting solution is added in the process of preparing cellulose fibers from plant pulp, and the antibacterial fibers are obtained. The viscose fibers prepared with the method touch soft and have good antibacterial activity, and the antibacterial activity is long-lasting.

Description

technical field [0001] The invention relates to a preparation method of viscose fiber, in particular to a preparation method of antibacterial viscose fiber, more specifically, the present invention relates to a preparation method of mugwort antibacterial viscose fiber. Background technique [0002] With the improvement of people's living standards, people's requirements for textile and clothing are getting higher and higher, especially for functional and health-care requirements, such as antistatic, anti-flame retardant, antibacterial and so on. [0003] For antibacterial textiles, it is mainly divided into two categories: one is antibacterial textiles processed after finishing, which are widely used due to their simple process, large selection of antibacterial agents, and wide applicability. However, the application of such antibacterial textiles also shows many problems, such as the persistence of antibacterial effect and the safety of leachable substances to the human bod...
