Abstract

The invention provides a vegetable dye for fabrics. The vegetable dye is prepared from, by weight, 15-25 parts of a plant coloring agent, 25-45 parts of dimethyl carbonate, 1-3 parts of urea, 2-5 parts of polyethylene glycol, 0.8-1.5 parts of sodium polyacrylate, 0.5-1 part of cellulose sodium sulfonate, 0.3-0.5 part of diphenylamine, 1.5-3 parts of sodium bicarbonate, 4-9 parts of ethylenediaminetetraacetic acid and 50-90 parts of deionized water. The vegetable dye for the fabrics is also prepared from, by weight, 2-7 parts of an antibacterial agent, wherein the antibacterial agent is chitosan or chitin. The invention further provides a preparation method of the vegetable dye. The method is simple in operation and mild in condition. The vegetable dye for the fabrics has the advantages that a natural plant extract is adopted as the vegetable dye, the vegetable dye is safe, environmentally friendly, easy to degrade, and poisonless and harmless for the human body, through the auxiliaryaction of the polyethylene glycol, the cellulose sodium sulfonate, the diphenylamine, the sodium polyacrylate and the sodium bicarbonate, the color fixing rate is high, the vegetable dye does not falloff easily, and the practical significance is higher.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a vegetable dye for fabric and a preparation method thereof. Background technique [0002] Textile dyes are divided into natural dyes and synthetic dyes, most of which are synthetic dyes on the market. Synthetic dyes have certain safety hazards to human health, and may cause skin allergies. The production process will also produce a large amount of harmful substances and a large amount of waste water, which will pollute the environment and cause waste of water resources. And produce light pollution, so synthetic dyes cause great pressure to the ecological environment. [0003] Moreover, with the improvement of people's living standards, the quality of life has been greatly improved, health has become a topic of current people's relationship, and the pursuit of green products and green consumption has become an important demand. At present, synthetic dyes can no longer meet peop...
