Description
Technical Field
The invention relates to a preparation process of a dye, in particular to a preparation process of a natural plant dye.
Background
The dye is divided into two categories of natural dye and synthetic dye, is a substance which can make certain color attached on fiber and is not easy to fall off or change color. Dyes are usually soluble in water and some require a mordant to enable the dye to adhere to the fiber. Most of the existing dyes are synthesized, which not only seriously pollutes the environment, but also easily causes harm to wearers. After being impregnated with traditional chemical dyes, clothing often emits harmful and pungent gases. And natural vegetable dyes, because of their: has wide source, no toxicity, mild property and soft color and luster, and is favored by more and more consumers.
In dye natural plants, purple cabbage and cotinus coggygria are rich in sources and high in pigment content; the natural pigment contained in the natural pigment is convenient to extract, the stability is good, the dye uptake and the color fastness are high after coloring, and the natural pigment has a great market prospect. However, the natural plant pigments extracted from plants have been difficult to popularize because of their complicated extraction process, high product price, and limited application range.
Therefore, a pure natural-burning plant dye with simple preparation process and good color fastness needs to be developed.
Disclosure of Invention
in order to solve the existing problems, the invention provides a preparation process of a natural plant dye. The invention is realized by the following technical scheme.
A manufacturing process of a natural plant dye comprises the following steps:
S1, cutting purple cabbage into small pieces;
S2, adding distilled water into the purple cabbage cut into small pieces according to the mass ratio of the material liquid of 1:3-1:10, and soaking for 20-60 minutes at the temperature of 40-100 ℃ under the condition of not isolating air to obtain a purple cabbage dye soaking solution;
S3, standing the purple cabbage soaking solution for 20-120 minutes, and filtering to obtain a purple cabbage extracting solution;
s4, adding a color regulator into the purple cabbage extracting solution to obtain purple cabbage dye liquor;
The toner is one or more of alum, blue vitriol, melanterite or plant toner.
Preferably, the plant toner is a cotinus coggygria extract.
Further preferably, the preparation method of the smoke tree extracting solution comprises the following steps:
S1, cutting cotinus coggygria into small blocks, adding distilled water according to the mass ratio of 1:3-1:10, and soaking for 20-60 minutes at the temperature of 40-100 ℃ under the condition of not isolating air to obtain cotinus coggygria dye soaking solution;
S2, standing the cotinus coggygria soaking solution for 20-120 minutes, and filtering to obtain the cotinus coggygria extracting solution.
Preferably, the purple cabbage dye solution and the cotinus coggygria extracting solution are mixed according to the mass ratio of 1:0-5: 1.
the invention has the beneficial effects that:
The invention relates to a process for preparing natural plant dye, which comprises the steps of taking purple cabbage as a main raw material, soaking, extracting, combining with alum, blue vitriol and copperas by using smoke tree extracting solution to prepare dye solutions with different colors; the preparation process is simple to operate, and the extracted natural plant dye is high in dye uptake and color fastness and is not suitable for decolorization. Meanwhile, the natural plant dye has less added chemical components, can effectively reduce the damage of the chemical components in the dye to human bodies, and the prepared dye has elegant color and classical aesthetic feeling and can be used for dip-dyeing of high-grade fabrics.
