Abstract

The invention provides artemisinin cellulose fiber and a preparation method thereof. The preparation method comprises an artemisinin dispersion liquid preparation step. The artemisinin dispersion liquid is prepared from the following ingredients in parts by weight: 1 to 1.5 parts of artemisinin, 0.8 to 1.1 parts of rose fruit oil, 2 to 3 parts of cedar camphor, 0.4 to 0.5 part of sodium surfactin,0.6 to 0.7 part of sodium alginate, 3 to 4 parts of sodium dodecyl benzene sulfonate, 7.5 to 8.2 parts of ethyl acetate, 2.5 to 3.4 parts of sodium hexametaphosphate and 8.2 to 8.8 parts of normal propyl alcohol. The cellulose fiber disclosed by the invention has the characteristics of good antibacterial and acarus killing functions, water absorption and water vapor permeability performance, highdye uptake and small surface dyeing.

Description

technical field [0001] The invention relates to an artemisinin cellulose fiber and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] The traditional cellulose fiber is made of natural fiber (wood fiber, cotton linter) as raw material, through alkalization, aging, sulfonation and other processes to make soluble cellulose xanthate, and then dissolved in dilute lye to make viscose , made by wet spinning, also known as viscose fiber; ordinary viscose fiber has general physical and mechanical properties and chemical properties, and is divided into cotton type, wool type and filament type, commonly known as artificial cotton, artificial wool and Rayon. [0003] Cellulose fibers are more absorbent, breathable, and softer than cotton and hemp fibers. [0004] Cellulose fiber is characterized by good dyeability, high brightness, comfortable wearing, dilute alkali resistance and good hygroscopicity. Therefore, it is widely lov...
