Embodiment 1

[0024] A preparation process for granular vegetable dyes, specifically comprising the steps of:

[0025] (1) Material selection: put freshly picked plant petals into a mortar, pound them into slag with a pestle, then pour clean water into the mortar, stir for 3 minutes to obtain a mixed solution, wherein the clear water The weight ratio to the plant petals is 1:8;

[0026] (2) Removal of slag: pass the above-mentioned uniformly stirred mixed solution through a slag removal net to remove particulate impurities in the mixed solution to obtain a filtrate;

[0027] (3) Preparation: Heat the above filtrate at a heating rate of 4°C / min. When the filtrate is heated for 10 minutes, put Yuanming powder into the filtrate while stirring. After heating for another 10 minutes, pour it into the filtrate Add the antibacterial auxiliary agent while stirring, and finally heat to boiling water to obtain a dyeing solution, wherein the weight ratio of the Yuanming powder to the filtrate is 1:3, ...

Embodiment 2

[0031] A preparation process for granular vegetable dyes, specifically comprising the steps of:

[0032] (1) Material selection: put freshly picked plant petals into a mortar, pound them into slag with a pestle, then pour clean water into the mortar, stir for 5 minutes to obtain a mixed solution, wherein the clear water The weight ratio to the plant petals is 1:12;

[0033] (2) Removal of slag: pass the above-mentioned uniformly stirred mixed solution through a slag removal net to remove particulate impurities in the mixed solution to obtain a filtrate;

[0034] (3) Preparation: Heat the above filtrate at a heating rate of 5°C / min. When the filtrate is heated for 8 minutes, put Yuanming powder into the filtrate while stirring. After heating for another 8 minutes, pour it into the filtrate Add the antibacterial auxiliary agent while stirring, and finally heat to boiling water to obtain a dyeing solution, wherein the weight ratio of the yuanming powder to the filtrate is 1:5, a...

Embodiment 3

[0038] A preparation process for granular vegetable dyes, specifically comprising the steps of:

[0039] (1) Material selection: put freshly picked plant petals into a mortar, pound them into slag with a pestle, then pour clean water into the mortar, stir for 4 minutes to obtain a mixed solution, wherein the clear water The weight ratio to the plant petals is 1:10;

[0040] (2) Removal of slag: pass the above-mentioned uniformly stirred mixed solution through a slag removal net to remove particulate impurities in the mixed solution to obtain a filtrate;

[0041] (3) Preparation: Heat the above filtrate at a heating rate of 4.5°C / min. When the filtrate is heated for 9 minutes, add Yuanming powder to the filtrate while stirring. After heating for another 9 minutes, pour it into the filtrate Add the antibacterial auxiliary agent while stirring, and finally heat to boiling water to obtain a dyeing solution, wherein the weight ratio of the yuanming powder to the filtrate is 1:4, a...

Abstract

The invention discloses a granular vegetable dye preparation process. The preparation process includes steps: selecting newly-picked plant petals, adding into a mortar, pounding with a pestle, pouringclear water into the mortar, and stirring for 3-5min to obtain mixed liquid; enabling the well stirred mixed liquid to pass through a residue removal net to remove granular impurities from the mixedliquid to obtain filtrate; heating the filtrate by a heating rate of 4-5 DEG C / min, when the filtrate is heating for 8-10min, adding anhydrous sodium sulphate into the filtrate while stirring, addingan antibacterial auxiliary agent into the filtrate while stirring after heating for 8-10min, and finally heating to boil to obtain dye solution; pouring the dye solution into a filter screen, taking out filter residues in the filter screen, adding a coal dye into the filter residues, and stirring for 4-6min to obtain dyed residues. By the granular vegetable dye preparation process, a vegetable dyewith flower fragrance can be obtained, and an antibacterial effect and environmental friendliness are realized.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a preparation process of granular vegetable dyes. Background technique [0002] As we all know, plant dyes are non-toxic and harmless, and will not cause any harm to human health. The dyed fabrics are natural in color and shape, durable, and have insect-proof and anti-bacterial effects, which are not available in chemical dyes. They are especially suitable for Children's clothing, underwear, footwear, car interior, luggage, interior, bedding, etc. [0003] With the continuous development of the clothing industry, the application of plant dyes is becoming more and more extensive. Today, the technical requirements for plant dyes are gradually increasing. Not only are the dyed fibers required to have antibacterial and comfortable effects, but also the color of the dye High fastness, obviously traditional plant dyes can not meet the above requirements.
