Steel blue wheat straw preparation dye and production method thereof

Abstract

The invention relates to a steel blue wheat straw preparation dye and a production method thereof. Polygonum tinctorium leaf stalk, cornflower petal, Chinese toona leaf, alum, an iron ion compound solution and mineral water are adopted as main raw materials. The production method mainly comprises the following steps: choosing materials, cutting, drying, immersing, carrying out hot boiling, mixing, precipitating, and dyeing to obtain a finished product. The steel blue wheat straw preparation dye produced from pure natural plants has the advantages of pure naturalness, no pollution, environmental protection, and no toxic side effects to human bodies.

Description

Technical field: [0001] The invention relates to a plant dye, in particular to a method for preparing a steely blue wheat straw dye and a production method. Background technique: [0002] In the prior art, there are many methods of dyeing wheat straw, the main raw material for making wheat straw paintings, into just blue color, but most of the dyes are chemical dyes, and the dyed just blue color is impure and easy to fade, which is not only not environmentally friendly, but some dyes are During the dyeing process, toxic gases will even be produced, threatening human health. [0003] Thereby, lack a kind of plant dyestuff that dyes wheat straw into different colors in the field of wheat straw painting production, especially the pure natural vegetable dye that dyes wheat straw into just blue color, the just blue color wheat straw that it dyes is not only pure in color, and can be used for other purposes. The wheat straw paintings made of materials are bright and bright, not...

Problems solved by technology

[0002] In the prior art, there are many methods of dyeing wheat straw, the main raw material for making wheat straw paintings, into steel blue, but most of the dyes are chemical dyes. The color of just blue is impure and easy to fade. Not only is it not environmentally friendly, some dyes may even produce toxic gases during the dyeing process, which threatens human health.

[0003]Therefore, in the field of wheat straw painting production, there is a lack of a plant dye that can dye wheat straw into different colors, especially a pure natural vegetable dye that can dye wheat straw into just blue , the blue-colored wheat straw dyed by it is not only pure in color, but the wheat straw painting made of its material is bright and bright, not easy to fade, and it is green and environmentally friendly. The hazards caused by other toxic and harmful chemical dyes to people's bodies during the dyeing process
