Problems solved by technology

The above-mentioned existing inventions have all obtained non-toxic viscose fibers with antibacterial effects, but in the production and preparation process, a large amount of organic amines are inevitably used as surfactants and stabilizers, which not only makes the production process not environmentally friendly , and the waste water produced is likely to lead to eutrophication of the water body. In addition, the organic amine stabilizers used will cause certain harm to the human body

Abstract

The invention relates to a method for preparing an anti-bacterial viscose fiber by taking a nano-silver colloid solution as an additive. The method comprises the steps of meal mixing, colloid preparing, spinning, bundling, cutting, refining, drying and packaging; the additive nano-silver colloid solution is formed by mixing a honewort extract solution with silver nitrate in proportion and then performing incubation on the mixture. The viscose fiber produced through the method has the higher anti-bacterial, sterilizing and ultraviolet-proof effects, is lasting in anti-bacterial effect and has no toxic or side effect on a human body.

Description

technical field [0001] The invention belongs to the field of antibacterial fibers, in particular to a method for producing antibacterial fibers by compounding nano-silver colloid solution prepared by biologically active substances and cellulose pulp. Background technique [0002] At present, synthetic fibers occupy a large share of the market of clothing, sanitary materials, and household products due to their advantages such as low production cost and wide range of raw material sources. By modifying it to add new functions, synthetic fibers with new functions are designed and synthesized. For example, the common antibacterial fibers on the market are mostly synthetic fibers, with organic antibacterial agents as functional additive components, and composite fibers are generally obtained through melt spinning. Although these fibers are low in cost and have certain antibacterial effects, at the same time they also have some defects that have not been overcome, such as poor hy...
