Embodiment 1

[0019] Embodiment one: the color scheme of cyan color dyeing

[0020] Textile material: 100% mulberry silk fabric after desizing and degumming pre-treatment; Dyestuff: Coptis chinensis, purified natural plant indigo.

[0021] (1) Extraction of Coptidis dyeing solution: crush 100 g of Coptidis Rhizoma and soak in distilled water for 24 hours; decoct for 1 hour and then filter repeatedly 3 times to obtain 1 L of Coptidis Coptidis dyeing solution.

[0022] (2) Add 10g of natural plant indigo extracted through fermentation and other techniques, 4g / L of caustic soda, and 6g / L of sodium dithionite into 1L of coptis dyeing liquor, add 100g of mulberry silk fabric after reduction at 60°C for 10min, and then add chlorinated Sodium 40g / L, adjust the pH value to 7, dye at 60°C for 40min, rinse with cold water and oxidize, and dry in the air.

Embodiment 2

[0023] Embodiment two: the color scheme of tan

[0024] Textile material: 100% cotton fabric desized, scoured and bleached; dyes: hematoxylin, coptis.

[0025] (1) Extraction of hematoxylin dye solution: crush 50 g hematoxylin and soak in distilled water for 24 hours; decoct for 1 hour and filter repeatedly 3 times to obtain 1 L hematoxylin dye solution.

[0026] (2) Extraction of Coptis Rhizoma Dyeing Solution: crush 100 g of Coptidis Rhizoma and soak in distilled water for 24 hours; decoct for 1 hour and then filter repeatedly 3 times to obtain 1 L of Coptidis Coptis Rhizoma Dyeing Solution.

[0027] (3) Mix 1L hematoxylin dye solution with 1L coptis dye solution, add 100g cotton fabric, add 40g / L sodium chloride, adjust pH to 7, dye at 90°C for 60min, rinse with cold water, and dry in the air.

Embodiment 3

[0028] Embodiment three: the color scheme of purple blue dyeing

[0029] Textile material: 100% mulberry silk fabric after desizing and degumming pre-treatment; Dyestuff: hematoxylin, purified natural plant indigo

[0030] (1) Extraction of hematoxylin dye solution: crush 50 g hematoxylin and soak in distilled water for 24 hours; decoct for 1 hour and filter repeatedly 3 times to obtain 1 L hematoxylin dye solution.

[0031] (2) Add 10g of natural plant indigo, 4g / L of caustic soda, and 6g / L of sodium dithionite to 1L of hematoxylin dye solution, add 100g of mulberry silk fabric after reduction at 60°C for 10min, and then add chlorine Sodium chloride 40g / L, adjust the pH value to 7, dye at 60°C for 40min, rinse with cold water, oxidize, and dry in the air.

Abstract

The invention discloses a method for dying fabrics by the color combination of vegetable dyes, which belongs to the technical field of the fabrics. The method comprises the following steps that two and more than two extracted vegetable dyes are mixed in a certain proportion, and a reasonable dying process is formulated according to the dying properties of various vegetable dyes to dye different colors on the different fabrics. The method breaks through the defect of single color variety of the vegetable dyes, enriches the color variety of the vegetable dyes on the fabrics, enlarges the use range of the vegetable dyes, enables the fabrics to be bright in color, colorful in colors and elegant in hues, and lays the foundation for the wide application of the vegetable dyes on the fabrics.

Description

technical field [0001] The invention relates to a color matching method of plant dyes, specifically mixing two or more extracted plant dyes in a certain proportion, and then formulating a reasonable dyeing process to dye different textiles according to the dyeing properties of various plant dyes. different colors. It belongs to the technical field of textiles. Background technique [0002] Some synthetic dyes used in textiles have been gradually banned because of their serious environmental pollution and harmfulness to human health. Since the raw material of synthetic dyes is mainly petroleum, in the long run, its resources will become increasingly scarce, which does not meet the requirements of sustainable development. Moreover, "returning to nature" has become the trend of the times. Thus, in recent years, people have paid more attention to traditional natural dyes. Since the application of natural plant fuels has a long history, various plant fuels have become more and ...
