Embodiment 1

[0016] The preparation method of this plant dyestuff adopts the raw material of following weight:

[0017] 4 kg glutinous rice grass; 6 kg red vine;

[0018] Its production steps are as follows:

[0019] A. Choose 4 kg of glutinous rice grass, grind it into powder with a traditional Chinese medicine grinder, put it in an extraction tank, add 100 mg of cellulase, 100 mg of pectinase, and 100 mg of protease in 100 kg of aqueous solution of pH=4, boil until Boil and keep for 15 to 25 minutes, stir during cooking, and then filter to obtain the filtrate;

[0020] B, mash the red vine to get the red vine material;

[0021] C. Add the filtrate prepared in step A to the red rattan paste prepared in step B, and stir for 0.5-1 hour to obtain a mixture;

[0022] D. Boil the mixture prepared in step C until boiling and keep it for 5-6 hours to obtain the vegetable dye.

Embodiment 2

[0024] The preparation method of this plant dyestuff adopts the raw material of following weight:

[0025] Glutinous rice grass 5 kg; red vine 6.8 kg;

[0026] Its production steps are as follows:

[0027] A. Choose 5 kg of glutinous rice grass, grind it into powder with a traditional Chinese medicine pulverizer, put it in an extraction tank, add 150 mg of cellulase, 150 mg of pectinase, and 150 mg of protease in 150 kg of aqueous solution of pH=4, boil until Boil and keep for 15 to 25 minutes, stir during cooking, and then filter to obtain the filtrate;

[0028] B, mash the red vine to get the red vine material;

[0029] C. Add the filtrate prepared in step A to the red rattan paste prepared in step B, and stir for 0.5-1 hour to obtain a mixture;

[0030] D. Boil the mixture prepared in step C until boiling and keep it for 5-6 hours to obtain the vegetable dye.

Abstract

The invention relates to the field of plant dyes, in particular to a preparing method for a plant dye. The method comprises the steps that firstly, by weight, 5 parts of digitaria ciliaris is selected, and 1 part of cellulase, 1 part of pectinase and 1 part of protease are added into a water solution accounting for 100 parts, boiled, stirred and filtered to obtain filter liquor, wherein the pH of the water solution is 4; secondly, sargentg loryvine stems are mashed, and a minced sargentg loryvine stem material is obtained; thirdly, the filter liquor prepared in the first step is added into the minced sargentg loryvine stem material prepared in the second step and stirred, and a mixture is obtained; fourthly, the mixture prepared in the third step is boiled and maintained for 5-6 hours in boiling, and the plant dye is obtained. By means of the method, the problems that synthetic dyes contain carcinogenic substances, can damage the human bodies and are not environmentally friendly are solved.

Description

technical field [0001] The invention relates to the field of plant dyes, in particular to a preparation method of plant dyes. Background technique [0002] Dye is a substance that can color fibers and other materials. It directly contacts people's skin during use. The raw materials and intermediates of commonly used synthetic dyes often contain carcinogenic substances, which not only seriously pollute the environment, but also cause direct wear. or producers are harmed. With the improvement of the quality of life, people pay more and more attention to health and pursue the products of original ecology and natural materials. Natural dyes extracted from plants are biodegradable, non-toxic and harmless because of their good compatibility with the environment. , and even has special health effects on the human body and is favored by people; glutinous rice grass and red rattan are two kinds of Chinese herbal medicines, and glutinous rice grass is the rooted whole plant of the pl...
