Embodiment Construction

[0010] The present invention will be further described below in conjunction with embodiment.

[0011] A kind of same-color dyeing process of wool / acrylic fiber blended fabric, said process at least includes the following steps: a. Fabric washing: wash the wool blended fabric in warm water at 40°C, dehydrate after removing impurities; b. Dyeing: wash the After the fabric is placed in the dyeing machine, add 2% owf leveling agent, the leveling agent is the mixture of fatty alcohol polyoxyethylene ether and sodium methylene dinaphthalene sulfonate; the fatty alcohol polyoxyethylene ether and The dosage of sodium methylene dinaphthalene sulfonate is 1:1; the mixed dye composed of vinylsulfone sulfate and disperse cationic dye is used for dyeing, and the dyeing bath ratio is 1:10; the pH value is adjusted by acetic acid during the dyeing process 4~5; When dyeing, use 70°C to bathe, then raise the temperature to 85°C at 1°C / min, keep it for 10 minutes, then raise the temperature to ...

Abstract

The invention provides a homochromatic dyeing process of wool / acrylic fiber blended fabric, which comprises the following steps: A)washing fabric; B)dyeing: compositing 1-2%owf leveling agent, a reactive dye and a dispersion-type cationic dye to form a mixed dye, wherein the bath ratio is 1: 10, adjusting the pH value by acetic acid to 4.5-5; bathing at the temperature of 70 DEG C while dyeing, then heating to the temperature of 85 DEG C with rate of 1 DEG C / min, insulating for 10 minutes, heating to 95 DEG C with rate of 0.5 DEG C / min, insulating for 20 minutes, heating to 100 DEG C with rate of 0.5 DEG C / min, insulating for 20 minutes; C) slowly cooling; D)fixing color, washing the dyed fabric by water with temperature of 50 DEG C, adding 10%owf fixing agent, immersing for 30-50 minutes under normal temperature; and E)drying. The homochromatic dyeing process has the advantage of good homochromatic dyeing effect of the blended fabric, aberration delta E of acrylic fiber and wool fiber is less than 3, and the staining fastness and fading fastness of the dyed fabric can reach more than grade 4.

Description

technical field [0001] The invention relates to a fabric dyeing process, in particular to a same-color dyeing process of wool / acrylic fiber blended fabric. Background technique [0002] Wool is an important natural fiber, which is widely used in high-grade textile fabrics. However, wool fiber has complex physical and chemical structures, and its surface layer has a hydrophobic scale layer structure, which is extremely unfavorable to the adsorption and dyeing of dye molecules, and at the same time prevents dyes from Diffusion into the fiber. Acrylic fiber is soft, light, warm, corrosion-resistant, and sun-resistant. It is about 10% lighter than wool and more than twice as strong. It is called artificial wool. Acrylic fiber will not be moldy and moth-eaten, and its resistance to light is 1 times greater than wool and 10 times greater than cotton. Acrylic and wool learn from each other in terms of characteristics, and they are blended to improve the wearability of the fabric....
