Application of alkannin serving as dye

Abstract

The invention relates to application of alkannin serving as a dye, which comprises the following steps of: (1) extracting the alkannin from lithospermum; and (2) printing and dyeing the alkannin on atextile for dyeing. Compared with the prior art, the application uses the alkannin extracted from natural lithospermum as the dye to print and dye the textile, has an environmentally-friendly extraction process, and prevents the wide use of organic solvents with large hazard; and the extracted alkannin is natural and nontoxic, has mild performance, has the effects of clearing heat and releasing toxin, is environmentally-friendly and natural, is favorable for health, and can be taken as a purple dye to be widely applied in the garment sector.

Description

technical field [0001] The invention relates to shikonin, in particular to the application of shikonin as a dye. Background technique [0002] The dyeing of ancient Chinese clothes is to extract pigments from the leaves, stems and roots of plants to dye clothes. With the development of science and technology, most of the modern dyes are chemically synthesized dyes. The human body will be harmful. On the other hand, these dyes need to use a lot of chemical reagents in the production process. The production environment in the factory is poor, and it will cause serious pollution to the environment and destroy the ecological balance. Therefore, the concept of green environmental protection and returning to nature should be advocated, and natural dyes should be sought again. Contents of the invention [0003] The purpose of the present invention is to provide an environmentally friendly and reasonable application of shikonin as a dye in order to overcome the above-mentioned de...
