Problems solved by technology

But DMF is harmful to human body and environment
[0008] (4) Use natural lipids as dyeing auxiliaries to dye wool fabrics with disperse dyes, but natural lipids are expensive and should not be used in the printing and dyeing industry
There is still a long way to go to achieve the same color in the same bath dyeing of silk and wool interwoven fabrics or blended fabrics, and none of them mentioned the use of disperse dyes

Embodiment 1

[0038] The fabric is a silk-wool interwoven fabric, the warp is 4 / 20 / 22D real silk, the weft is 62Ne / 2 strong-twist wool yarn, and the structure is a plain weave variation structure, and real silk: wool is 32:68 (mass ratio).

[0039] Pre-treatment: Accurately weigh 550 g of the above-mentioned silk wool fabric, add 8.25 kg of water at a bath ratio of 1:15, add 2 g / L of Genencor MU-823 biological protease, and then use Na 2 CO 3 Adjust the pH value of the treatment solution to 7.8, raise the temperature to 55°C, stir continuously, adjust the pH value to 4 with acetic acid after holding for 1 hour and raise the temperature to 75°C, circulate the fabric for 5 minutes, then cool down to 40°C, dehydrate, rinse with water, dehydrate, and dry Dry.

[0040] Dyeing: Accurately weigh 2 g of the silk-wool interwoven fabric, prepare the dye solution at a bath ratio of 1:50, add disperse fluorescent yellow 8GFF 2% (percentage relative to the fabric mass), and auxiliary agent ZWS 4g / L; dy...

Embodiment 2

[0043] The dye is disperse ruby ​​S-2GHL, the dosage is 1% of the fabric mass, the dosage of auxiliary agent ZWS is 4g / L, and other parameters are the same as in Example 1. After testing, the dyed finished product has a dry rubbing fastness of grade 4, a wet rubbing fastness of 3-4 grades, and a soaping fastness of 3-4 grades. The dye homochromaticity is grade 4.5 (ΔE=0.86).

Embodiment 3

[0045] The dye is disperse blue 2BLN, the consumption is 2% of the fabric quality, the ZWS consumption is 6g / L, and other parameters are the same as in Example 1. After testing, the dyed finished product has a dry rubbing fastness of 4-5 grades, a wet rubbing fastness of 3 grades, a soaping fastness of 3-4 grades, and a dyeing homochromaticity of 4.5 grades (ΔE=1.03).

Abstract

A method for dyeing the interwoven silk-wool blended fabric includes pretreating with the pretreating liquid containing biologic proteinase and dyeing with disperse dye and solubilizer which contains sodium C12-C18 alkyl benzene sulfonate, polyoxyethylenated alcohol, methyl benzoate, phenylmethanol, octadecyl naphthalenesulfonic acid and water. Its advantages are high colour fastness and low environmental pollution.

Description

technical field [0001] The invention relates to a dyeing method in the field of textile printing and dyeing production, in particular to a method for dyeing silk-wool blended and interwoven fabrics with disperse dyes. Background technique [0002] Silk and wool are both natural silkworm white fibers. Silk has bright luster, smoothness, softness, lightness, and excellent hygroscopicity. The main body is silk fibroin and the outside is surrounded by sericin. Wool has excellent qualities such as luster, softness, elasticity, moisture absorption, and heat preservation. The hair shaft of fine wool is composed of a scale layer and a cortex layer. Due to the above characteristics, the fabrics woven with silk and wool are all high-grade products, especially the products of interweaving or blending silk and wool have both advantages, making them a new type of fabric with beautiful and elegant appearance, unique style and comfortable wearing. much attention. However, due to the dif...
