Problems solved by technology

[0003] At present, the colored antibacterial viscose fiber produced by the pre-spinning injection process with natural plant source dyes has not been reported. Most of the commonly used antibacterial agents are inorganic or organic antibacterial agents. Organic antibacterial agents are rapid and efficient in inhibiting bacteria and bacteria. The human body has side effects, bacteria are prone to drug resistance, poor timeliness, and high temperature resistance; inorganic antibacterial agents are mainly metal inorganic salts and antibacterial zeolites with antibacterial effects
Heavy metal ions in such antibacterial agents are easily absorbed by the human body through contact with human skin, causing potential harm to human health
Natural plant-derived antibacterial agents have the advantages of high antibacterial efficiency, safety to the human body, no resistance to bacteria, and environmental protection. Natural plant-derived dyes are also safe to the human body and environmentally friendly. Therefore, they are increasingly valued in applications. However, the low color fastness of vegetable dyes is also the main factor restricting the large-scale use of vegetable dyes. Usually, mordants are used to solve this problem, and the mordants currently used are mainly metal mordants. Because they contain heavy metal ions, they are also harmful to the human body. Security poses hidden dangers
The use of plant-derived mordants can solve this problem, but so far in the prior art, there is no such thing as a fabric with antibacterial function and richer colors that uses plant-derived dyes, mordants and plant-derived antibacterial agents. Viscose fiber with high fastness is available
And how to apply the plant source extract as the dyestuff and antibacterial agent and mordant used for spinning has not yet reasonable, simple and mature production technology, therefore, urgently need to study a kind of preparation method of plant source colored antibacterial viscose fiber

Abstract

The invention discloses a plant-derived colored antibacterial viscose fiber and a preparation method thereof, wherein the fiber is light yellow to coffee in color, prepared textile fabrics are high in color fastness and high in bacteriostasis rate. The preparation comprises that any one of a gentian extract or a homalomena occulta extract or a mixture thereof as an antibacterial coloring agent and a dispersing agent as an auxiliary material are subjected to blended spinning with a viscose spinning solution, the fiber obtained after water washing in post-processing is subjected to color fixing bath treatment by a dyeing mordant obtained with any one of a persimmon peel extract or a loquat leaf extract or a mixture thereof as a dyeing mordant to obtain the product. The plant-derived colored antibacterial viscose fiber has the characteristics of excellent wearability, good textile processing performance, prominent anti-bacterial and bacteriostasis functions, high color fastness, and reasonable, simple, environmental-protection preparation process, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the technical field of functional cellulose fibers, in particular to a method for preparing plant-derived colored antibacterial viscose fibers. Background technique [0002] In the prior art, most of the colored viscose fibers are produced by synthetic dyes and conventional dyeing processes after spinning. Not only the cost is high, but also the quality of viscose fiber products and the fluctuation of dyeing and finishing process will be affected during the dyeing process. Cause problems such as uneven color and poor color fastness. Due to the use of synthetic dyes, a large amount of dyeing and finishing wastewater will be generated during the dyeing process, polluting the environment. At the same time, there are some colored antibacterial viscose fibers produced by pre-spinning injection. Although some problems have been initially solved, such as uniform color and high color fastness of the product, and low production cost an...
