Embodiment 1

[0014] Rinse the wool with clean water, let go of the cleaning solution, add water at a bath ratio of 1:50, add 20% (ratio to the mass of the textile, W / W) copper sulfate for pre-mordant dyeing at a temperature of 60°C, and release the liquid after mordanting for 30 minutes . The scutellaria dye powder was mixed with water to prepare a dye solution, the dye amount was 5g / 50g wool, the dye solution pH value was 3, the bath ratio was 1:20, and the dyeing solution was dyed for 2 hours at room temperature, then washed with water, and the wool obtained after dehydration was grass green. The pigment component baicalin contained in the scutellaria vegetable dye is more than 20%.

[0015] The invention uses natural dyes extracted from the Scutellaria baicalensis plant to dye a variety of colors. The color is soft, simple and natural, giving people a feeling of "returning to nature"; the dyeing fastness is good, the color is not faded in the sun, and it is soaped It does not change color a...

Embodiment 2

[0017] Rinse the wool with clean water, let go of the cleaning solution, dissolve the scutellaria dye powder in water to prepare a dye solution, dye it at a bath ratio of 1:30, the dye amount is 5g / 50g wool, the dye solution pH is 6.5, and 2% ( The ratio of the weight to the textile fabric, W / W) ferrous sulfate, was dyed with the same medium at 25°C for 0.5 hours, then washed with water, and the wool obtained after dehydration was brown. The pigment component baicalin contained in the scutellaria vegetable dye is more than 20%.

[0018] The invention uses natural dyes extracted from the Scutellaria baicalensis plant to dye a variety of colors. The color is soft, simple and natural, giving people a feeling of "returning to nature"; the dyeing fastness is good, the color is not faded in the sun, and it is soaped It does not change color afterwards, with good reproducibility and uniform dyeing; direct dyeing with existing dyeing equipment without adding equipment or increasing cost; ...

Embodiment 3

[0020] Take the silk crepe de chine and rinse with clean water, drain the cleaning solution, add water at a bath ratio of 1:20, add 10% (ratio to textile mass, W / W) alum pre-mordant, temperature 80 ℃, Mordant 2 hours later liquid. Dissolve the scutellaria dye powder with water to prepare a dye solution, dye it according to the bath ratio of 1:40, the dye amount is 5g / 50g silk crepe de chine, the dye solution pH value is 4, dyeing at room temperature for 2 hours, then add water to wash, the silk double obtained after dehydration The crepe is yellow. The pigment component baicalin contained in the scutellaria vegetable dye is more than 20%.

[0021] The invention uses natural dyes extracted from the Scutellaria baicalensis plant to dye a variety of colors. The color is soft, simple and natural, giving people a feeling of "returning to nature"; the dyeing fastness is good, the color is not faded in the sun, and it is soaped It does not change color afterwards, with good reproducibili...

Abstract

The invention opened a method of dying the true silk crepe-de-chine and the wool using scutellaria dyestuff. The process: a. put the scutellaria dyestuff which the pH is 3-6.5 on the true silk crepe-de-chine and the wool; b. do the fore and mordanting by the mordant which is 2-20 %( w / w). The dyestuff is the natural, soft, simple and innoxious to the human.

Description

Technical field [0001] The invention relates to a method in the technical field of textile printing and dyeing, in particular to a method for dyeing silk crepe de chine and wool with a skullcap vegetable dye. Background technique [0002] Scutellaria baicalensis Georgi (Scutellaria baicalensis Georgi) is a perennial herb of the Lamiaceae family. It is a commonly used Chinese medicine for clearing away heat and detoxification. It is mainly produced in Northwest and Northeast provinces (regions) of my country, among which Hebei, Shaanxi, Shandong and other places are more planted. Its main active ingredients are a variety of flavonoids and their derivatives. Among them, baicalin and baicalein are antibacterial active ingredients. Baicalin has a certain degree of anti-cancer activity. Baicalin can also treat hepatitis. The main pigment component in Scutellaria baicalin is Baicalin, which can be used to dye fabrics. [0003] After searching the existing technical literature, Sun Xin ...
