Abstract

The invention belongs to the technical field of dyes, and particularly relates to a purple vegetable dye. The purple vegetable dye is prepared from, by weight, 60-100 parts of pterocarpus santalinus,30-50 parts of purple perilla, 30-50 parts of caulis spatholobi, 5-9 parts of mulberries, 6-9 parts of sodium sulfite, 5-10 parts of polydimethylsiloxane, 1 part of a color fixing agent and 1 part ofa dispersing agent. The dye prepared by mixing plant raw materials with chemical agents is very environment-friendly; after the dye is used, the skin of a human body is not damaged, the dye retains the plant smell, the dyed cloth has a plant fragrance, and the color is natural and bright; and the preparation method is simple, and the preparation cost of the traditional plant dye is greatly reduced. Nontoxic raw materials are adopted, so the purple vegetable dye is safe and environment-friendly, has good biological solubility and environmental compatibility, is especially non-irritant to humanbodies, is suitable for dyeing underwear fabrics, and has good color and luster degree and good color fixing effect.

Description

technical field [0001] The invention belongs to the technical field of dyes, in particular to a purple vegetable dye. Background technique [0002] In ancient China, people used plant dyes to dye cloth in the process of making clothes. However, with the continuous improvement of industrial level, traditional plant dyes have been replaced by dyes made of chemical combinations. The main reason is that the preparation of chemical dyes is easier, the cost is lower, and the color is stable. But along with the continuous improvement of human living standards, people find that in the contact process between body skin and clothes, long-term friction can easily lead to skin allergies and other symptoms. The main reason is that the components in the chemical dyes used are harmful to the human body. Traditional plant dyes are not harmful to human skin, but the preparation of traditional dyes is too complicated. How to use modern dye preparation methods to prepare plant dyes has always...
