Problems solved by technology

[0004] Because the scale layer of wool hinders the diffusion of pigment, in the prior art, the hue of the dyed fabric obtained by the exhaust dyeing treatment of wool with the extract of yam yam is light, and the color fastness to rubbing of the fabric after dyeing is relatively poor

Embodiment 1

[0019] The wool fabric dyeing process of the Ranunculus yam extract of embodiment 1 comprises the following steps:

[0020] S1: Take yam as raw material, wash, dry and crush to get yam powder, add 1000ml of deionized water and lower ketone mixed solution for every 50g of yam powder, heat the mixed system to reflux at 100°C 2h, filter, and the extracted dye stock solution is directly used for dyeing wool fabrics;

[0021] S2: Add 5g of sodium hydroxymethyl cellulose to 1000ml of dyeing liquor, adjust the pH of the dyeing liquor to 4 with an acidic pH value regulator, enter the dyeing at room temperature according to the bath ratio of 1:30, slowly raise the temperature of the dyeing liquor to 90°C, and keep it warm React for 50 minutes, cool down to 60°C, keep it warm for 1 hour, then cool down to room temperature, and the dyeing is over;

[0022] S3: The wool fabric is washed, soaped, washed, and dried at room temperature in sequence.

[0023] The heating rate in S2 is 2°C / mi...

Embodiment 2

[0026] The difference between embodiment 2 and embodiment 1 is:

[0027] S1: Add 1000ml of deionized water and a mixed solution of lower ketones for every 70g of yam powder, heat the mixed system to reflux at 100°C for 1 hour, filter, and use the extracted dye stock solution directly for dyeing wool fabrics;

[0028] S2: Add 10g sodium hydroxymethyl cellulose to 1000ml dyeing solution, adjust the pH value of the dyeing solution to 3 with an acidic pH regulator, and dye at room temperature according to the liquor ratio of 1:40, slowly raise the temperature of the dyeing solution to 80°C, and keep it warm React for 90 minutes, cool down to 55°C, keep it warm for 2 hours, then cool down to room temperature, and the dyeing is over;

[0029] The dye solution in S2 also contains a mordant; the mordant is tin chloride.

[0030] The content of mordant in the dyeing liquor is 2g / L.

[0031] The heating rate in S2 is 1.4°C / min, and the cooling rate when the temperature of the dye liqu...

Embodiment 3

[0034] The difference between embodiment 3 and embodiment 2 is:

[0035] S1: Add 1000ml of deionized water and a mixed solution of lower ketones for every 60g of yam powder, heat the mixed system to 100°C and reflux for 1.5h, filter, and the extracted dye stock solution is directly used for dyeing wool fabrics;

[0036] S2: Add 7g of sodium hydroxymethyl cellulose to 1000ml dyeing solution, adjust the pH value of the dyeing solution to 3.5 with an acidic pH value regulator, enter the dyeing at room temperature according to the bath ratio of 1:35, slowly raise the temperature of the dyeing solution to 85°C, and keep it warm React for 70 minutes, cool down to 57°C, keep it warm for 1.5 hours, then cool down to room temperature, and the dyeing is over;

[0037] The mordant is copper sulfate. The content of mordant in the dyeing liquor is 4g / L.

[0038] The heating rate in S2 was 1.7°C / min, and the cooling rate when the dye liquor temperature dropped to 57°C was 2.5°C / min.

Abstract

The invention discloses a wool fabric dyeing process of a rhizoma dioscoreae cirrhosae extracting solution. The wool fabric dyeing process comprises the steps: textile pigment extraction, dyeing and fabric washing and drying. According to the wool fabric dyeing process of the rhizoma dioscoreae cirrhosae extracting solution, the rhizoma dioscoreae cirrhosae extracting solution is adopted as a dyeto directly dye a wool fabric, carboxymethyl cellulose sodium is added into dye liquor, the hue of the dyed wool fabric is deepened, and the color fastness to rubbing of the fabric is improved by onelevel.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing, in particular to a process for dyeing wool fabrics with yam yam extract. Background technique [0002] Natural plants have good biodegradability and environmental compatibility. As natural dyes for textiles, the color is soft and natural, and they often have certain medicinal and health effects while dyeing. [0003] In natural dyes, tannin dyes have ortho phenolic hydroxyl groups, which have good dyeing performance on protein fibers. At the same time, their phenolic hydroxyl groups also show certain antibacterial, anti-ultraviolet and anti-oxidation activities, and are natural dyes with special functions. representative species. Dioscorea is a vine belonging to the Dioscoreaceae family. The tubers of this species are rich in tannins, which can be extracted from tannins, or used to dye silk, cotton cloth, and fishnets; they can also be used as raw materials for wine making; used as medicin...
