Embodiment 1

[0032] A method of applying peony root pigment dyeing wool fabric, comprising the following steps:

[0033] Step 1, prepare peony root pigment

[0034] a. Excavate the roots of fresh first case red peony, wash them with water, remove impurities, and then dry them until the water content is no more than 10%. Then you can get dried peony roots. Crush the dried peony roots and pass through a 20-mesh sieve. Obtain peony root powder, set aside;

[0035] b. Add 5 times of its weight in ethanol solution to the peony root powder obtained in step a and soak, the mass concentration of ethanol solution is 70%, filter after soaking for 2d, collect the filtrate, and set aside; add its weight 5 times to the filter residue obtained after filtering times the ethanol solution, the mass concentration of the ethanol solution is 70%, filter after soaking for 2 days, collect the filtrate, then combine the two filtrates for subsequent use;

[0036] c. The combined filtrate obtained in step b i...

Embodiment 2

[0042] A method of applying peony root pigment dyeing wool fabric, comprising the following steps:

[0043] Step 1, the preparation of the peony root pigment is the same as in Example 1;

[0044] Step 2. Dyeing Wool Fabric with Peony Root Pigment

[0045] d. Take the wool fabric, wash it with water first, and dry it for later use;

[0046] e. Prepare a potassium sulfate aqueous solution with a mass concentration of 3%, add it to the mordant tank and heat it to 80°C, put the dried wool fabric obtained in step d into the potassium sulfate aqueous solution, and take it out after mordant dyeing at 80°C for 10 minutes. Wash with clear water to obtain mordant-dyed woolen fabric for subsequent use;

[0047] f. Take the prepared peony root pigment, add water to dissolve according to the ratio of material to liquid of 1:10, adjust the pH value to 5 after the dissolution is complete, and obtain the pigment solution for later use; add the pigment solution into the dyeing vat, and th...

Embodiment 3

[0050] The peony root pigment dyeing is applied to dyeing other protein-containing fabrics, such as rabbit hair, silk, etc., and the method is the same as in Example 1.

Abstract

The present invention mainly relates to a method for dyeing wool fabric with peony root pigment. Concentrate and dry to obtain the peony root pigment; step 2, apply the peony root pigment to dye the wool fabric, take the wool fabric, wash and dry, prepare an aqueous solution of potassium sulfate with a mass concentration of 3%, add it to the mordant tank and heat it to 80°C, and Put the wool fabric into potassium sulfate aqueous solution, take it out after mordant dyeing for 10 minutes, and wash it with clear water to obtain the wool fabric after mordant dyeing; take the prepared peony root pigment, add water to dissolve, adjust the pH value to 5, add it to the dyeing vat, and then mordant dye Put the finished woolen fabric into the pigment solution, heat the pigment solution to 100° C., and then keep it warm for 20 minutes. After dyeing, take it out, wash it, and dry it to complete the dyeing of the peony root pigment on the woolen fabric.

Description

technical field [0001] The invention relates to the field of preparation and application of pigment, in particular to a method for dyeing wool fabric with peony root pigment. Background technique [0002] At present, most of the pigments used are synthetic pigments, which belong to tar dyes, which not only have no nutritional value, but also are harmful to human body. Long-term use will endanger human health and cause cancer. Therefore, plant dyeing has been mentioned again. Moreover, natural pigments have attracted more and more attention in the field of scientific research, and have a tendency to replace artificial pigments. [0003] The whole body of peony is a treasure, and its root bark, leaves, flowers and fruits all have good application value. Cortex Moutan, the roots are excavated in autumn, the fine roots are removed, the root bark is stripped, and dried in the sun. Use raw or fried. "Compendium of Materia Medica": "Nourishing yin and reducing fire, detoxifying ...
