Description
Technical Field
The invention belongs to the field of textile dye technology and application, and particularly relates to a green pigment extracted from madder roots, and an extraction method and application thereof.
Background
The plant dye is extracted from roots, stems, leaves, flowers and fruits of plants, has good environmental compatibility, no toxicity and harm, no allergy and carcinogenicity to skin, better biodegradability and environmental compatibility, and has multiple functions of medicines, spices and the like besides the dyeing function. In the dyeing process, the medicines, the fragrance components and the pigment are absorbed by the fabric together, so that the dyed fabric has a special medicine health-care function for human bodies, and the added value of the dyed product is improved. Therefore, the natural dye is used for dyeing, which has important significance for reducing environmental pollution and promoting human health. However, the natural dye has incomplete color spectrum, and the application of the natural plant dye is greatly limited.
The green dye is not much, and the frozen green has rare sources and higher price; the other silkworm excrement is silkworm excrement and is dyed by sodium copper chlorophyllin, but the green silkworm excrement has poor heat resistance. And the natural dye has limited dyeing suitable for split dyeing due to different dyeing acid-base environments, and the split dyeing also increases the technical process and the cost.
Disclosure of Invention
In order to solve the problems of few varieties of green plant pigments and incomplete natural dye chromatography at present, the invention provides a method for preparing a green pigment by using madder roots, and the green pigment can be used for dyeing various textile materials.
In order to achieve the purpose, the invention adopts the following technical scheme:
a natural green pigment is extracted from radix Rubiae.
The extraction method of the natural green pigment comprises the following steps: adding radix Rubiae into acid solution, standing in dark for 24 hr, boiling the soaking solution for 30-60min, filtering, adding hard water into the residue, boiling for 30-60min, filtering, centrifuging the filtrate, and standing the supernatant at 20-30 deg.C for 3-5 days to obtain green pigment extractive solution.
Further, the acid solution is selected from an aqueous sulfuric acid solution, an aqueous nitric acid solution or an aqueous phosphoric acid solution.
Further, specifically, 10g of madder is added to an acid solution obtained by adding 2mL of acid to 100mL of deionized water.
The natural green pigment is used as a fiber coloring agent.
Furthermore, the application is that the fiber material is wetted in warm water, squeezed to be dry and put into green pigment extracting solution, the dyeing bath ratio is 1:10-1:50, the dyeing temperature is 70-120 ℃, and the dyeing time is 30-60 min.
Further, the fiber material includes a fiber, a yarn, a knitted fabric, a woven fabric, or a nonwoven fabric.
Further, the material of the fiber material comprises cellulose fiber, protein fiber or chemical fiber.
According to the method, madder roots are used as raw materials and extracted through a specific process, firstly, an acid solution is adopted for soaking and boiling, filtrate is removed after filtration, various impurities affecting pigment purity can be effectively removed, then, filter residues obtained through filtration are placed in hard water for boiling and extraction, an extracting solution is obtained after filtration, the filtrate is centrifuged, and supernatant is placed at 20-30 ℃ for 3-5 days to obtain a green pigment extracting solution, so that a fiber material can obtain a green chromatogram.
The extraction process adopted by the invention is simple and has low cost. The obtained pigment has good thermal stability, does not need any mordant and is also suitable for high-temperature dyeing conditions.
The pigment of the invention is suitable for developing ecological health care textile materials, such as clothes, underwear, scarves, hats, home textile bedding, sofa and automobile seat fabrics, surgical gowns and masks.
Detailed Description
The following examples further illustrate the present invention but are not to be construed as limiting the invention. Modifications or substitutions to methods, procedures, or conditions of the invention may be made without departing from the spirit and scope of the invention. The experimental methods and reagents of the formulations not specified in the examples are in accordance with the conventional conditions in the art.
Example 1
The method for extracting the green pigment from the madder root comprises the following steps: adding 2mL of sulfuric acid and 100mL of deionized water into 10g of madder, standing for 24 hours in the dark, boiling for 30-60 minutes, filtering, leaving filter residue, adding 100mL of hard water, boiling for 30-60 minutes, filtering, centrifuging the filtrate, and standing the supernatant for 3-5 days at 20-30 ℃.
Other acids may also be used for extraction, such as phosphoric acid, nitric acid.
Extracting pigment from madder root and dyeing: wetting the fiber material in warm water, squeezing and putting into a dye liquor, wherein the dyeing bath ratio is 1:10-1:50, the dyeing temperature is 70-120 ℃, and the dyeing time is 30-60 min.
The pigment of the invention can be used for dyeing various fiber materials, including but not limited to fibers, yarns, knitted fabrics, woven fabrics and non-woven fabrics. There is no limitation on the material of the fiber material, such as: cellulose fibers such as cotton, hemp, viscose and the like, protein fibers such as wool, silk and the like, and chemical fibers such as terylene, acrylon, chinlon, spandex, polypropylene and the like can be dyed by adopting the pigment.
The method utilizes madder which is commonly extracted from the market to carry out red spectrum dyeing to obtain green pigment through a specific process, namely, the fiber material can obtain green chromatogram.
The extraction process is simple, the cost is low, the obtained pigment has good thermal stability, no mordant is needed, and the method is also suitable for high-temperature dyeing conditions. Is suitable for developing ecological health care textile materials, such as clothes, underwear, scarves, hats, home textile bedding, sofa and automobile seat fabrics, surgical gowns and masks.
