Preparation method of wild chrysanthemum natural dye and preparation of anti-bacterial textiles adopting wild chrysanthemum natural dye

Abstract

The invention discloses a preparation method of wild chrysanthemum natural dye and preparation of anti-bacterial textiles adopting the wild chrysanthemum natural dye. The preparation method of the wild chrysanthemum natural dye is as follows: smashed wild chrysanthemum is added to an ethanol water solution, is subjected to reflux extraction for 0.5-2 h at the temperature ranging from 60 DEG C to 90 DEG C, an extracting solution is obtained, and the concentrated wild chrysanthemum natural dye is obtained by treating the extracting solution; the ethanol water solution comprises, in percentage by mass, 10%-40% of ethanol, each kilogram of the ethanol water solution contains 0.5-1.5 g of sodium carbonate, the mass ratio of the smashed wild chrysanthemum to the ethanol water solution is 1:(10-30), and the mass of the concentrated wild chrysanthemum natural dye is 1 / 6-1 / 2 of that of the ethanol water solution . Environmental pollution cannot be caused in the extraction process of the wild chrysanthemum natural dye, the extracting solution is taken as a dyeing agent and used for dyeing protein fiber, then the protein fiber has good anti-bacterial performance, soft color and luster and good color fastness, and the textiles made of the protein fiber are safe and comfortable to wear.

Description

technical field [0001] The invention relates to the preparation and application of natural dyes, in particular to a preparation method of wild chrysanthemum natural dyes and the preparation of antibacterial textiles. Background technique [0002] Natural dyes are mainly extracted from plant rhizomes, fruit shells, etc., which have good compatibility with the ecological environment and can be biodegraded. Some natural plant dyes come from Chinese herbal medicines. Besides dyeing, they also have the function of medicine and health care. Therefore, natural dyes have broad application prospects in the fields of high-grade real silk products, home textile products and decorations. [0003] Wild chrysanthemum is a perennial herb of Compositae. Mainly distributed in Jilin, Liaoning, Hebei, Henan and other places in China. Existing data show that wild chrysanthemum contains a variety of pharmacologically active ingredients, including luteolin, chrysanthemum ketone (birrhanonediol...

AI Technical Summary

Problems solved by technology

[0004] After searching the prior art documents, it was found that Shen Haijin and others published in the "Journal of Plant Resources and Environment" published in "The composition of phenolic components of 60% ethanol extract of wild chrysanthemum and its ability to scavenge free radicals and prevent mildew" in the article Mainly carried out analysis and research on the extraction of wild chrysanthemum and the composition and content of phenolic components. The extractant is a certain concentration of ethanol solution, and no other extractant is added. This method not only has poor extraction effect, but also takes a long time to extract (2 ~24h); People such as Nateepat Pitinidhipat pointed out in the article "Antibacterial Activity of Chrysanthemumindicum, Centellaasiatica and Andrographis paniculata against Bacillus cereus and Listeriamonocytogenes under Osmotic Stress" published in "Technical Report" that the wild chrysanthemum extract has certain antibacterial properties to Bacillus, Listeria; Poor, and its antibacterial effect is general, not suitable for the application and promotion of textiles

[0005] At present, the research on wild chrysanthemum is limited to traditional Chinese medicine and food coloring, and there is no report about the preparation method of wild chrysanthemum natural dye antibacterial functional textiles
