Preparation method of artemisia annua fiber

Abstract

The invention provides a preparation method of an artemisia annua fiber. The preparation method comprises the following steps: 1, preparing artemisia annua extract dispersion liquid; 2, preparing a reactive dye solution; 3, carrying out cationization on the fiber; 4, pretreating the fiber; and (5) coating the fiber. The content of artemisinin in the prepared fiber is high, and the prepared composite fiber has good performance; the production period is short and flexible, small-batch multi-variety operation can be achieved, and the stock pressure is reduced; The fiber prepared by the method disclosed by the invention has the characteristics of bright and soft gloss, good moisture absorption and moisture release properties and good fiber softness, also has relatively high dry breaking strength, wet breaking strength and dry breaking elongation, and has relatively good antibacterial and anti-mite effects; the dry breaking strength is 2.25 CN / dtex or above, the wet breaking strength is 1.25 CN / dtex or above, the dry breaking elongation is 9% or above, and the antibacterial rate is 95% or above.

Description

technical field [0001] The invention belongs to the field of light industry textiles, and in particular relates to a preparation method of Artemisia annua fiber. Background technique [0002] The textile industry is a traditional industry in China. With the rapid development of clothing, household and industrial textiles, the differentiation and individualization of textile products have become the focus of the development of various enterprises. Functional fibers as high-grade textile raw materials are generally improved by means of physical modification, chemical modification and molecular design to obtain fibers with specific properties, so that the original viscose fibers are stable in light and heat, conductive, Flame retardant, dyeing, antistatic, moisture absorption, fluffy, anti-pilling, anti-fouling and other aspects have been greatly improved. [0003] Regenerated cellulose fiber is made of natural cellulose (cotton, hemp, bamboo, tree, shrub) as raw material, wit...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the fibers with modified functions are added by blending the extracts of plant traditional Chinese medicines into the regenerated fiber fibers. This process will inevitably come into contact with a strong acid environment during the production process, which will more or less damage the extracts. and damage, and during the fiber forming process, the extract will be partially lost
