Embodiment 1

[0014] (1) Put sodium chloride, Pingpingjia, acid coacervation dyes and 1:2 metal complex dyes in a constant temperature water bath and stir evenly, then put the wool and silk blended fabric in a constant temperature water bath and dye for 30 minutes, The set temperature of the constant temperature water bath is 40°C;

[0015] (2) Raise the temperature of the solution in the constant temperature water bath to 97°C and continue dyeing for 60 minutes to obtain dyed wool and silk blended fabric.

Embodiment 2

[0017] (1) Put sodium chloride, Pingpingjia, acid coagulation dyes and 1:2 metal complex dyes in a constant temperature water bath and stir evenly, then put the wool and silk blended fabric in a constant temperature water bath and dye for 40 minutes, The set temperature of the constant temperature water bath is 30°C;

[0018] (2) Raise the temperature of the solution in the constant temperature water bath to 97° C. and continue dyeing for 50 minutes to obtain dyed wool and silk blended fabrics.

Embodiment 3

[0020] (1) Put sodium chloride, Pingpingjia, acid coacervation dyes and neutral ash in a constant temperature water bath in turn and stir evenly, then put the wool and silk blended fabric in a constant temperature water bath and dye for 35 minutes, the constant temperature water bath The set temperature of the pot is 35°C;

[0021] (2) Raise the temperature of the solution in the constant temperature water bath to 97°C and continue dyeing for 55 minutes to obtain dyed wool and silk blended fabric.

[0022] The method for dyeing wool and silk blended fabric disclosed by the present invention adopts the same-color dyeing technique to dye the wool and silk blended fabric. The blended fabric has good homochromaticity and is almost non-destructive to the blended fabric. No discoloration, less waste water and waste generated in the preparation process, greatly reducing water quality and environmental pollution.

Abstract

The invention discloses a dyeing method of a wool-silk blended fabric. The dyeing method comprises the following steps: sequentially adding sodium chloride, dye leveler, acidic condense dye and metal complex dye based on 1: 2 to a constant-temperature water bath and uniformly stirring; adding the wool-silk blended fabric to the constant-temperature water bath, and dyeing, wherein the setting temperature of the constant-temperature water bath is 30 to 40 DEG C; raising the temperature of the solution in the constant-temperature water bath to reach 97 DEG C; and continuously dyeing to obtain the dyed wool-silk blended fabric. According to the mode mentioned above, the dyeing method of the wool-silk blended fabric has the advantages that the wool-silk blended fabric is dyed by homochromy dyeing technology, so that the blended fabric is high in homochromatism and is nearly not damaged; the dye is firmly attached on the blended fabric and cannot be decoloured after placing under the blazing sun; and little wastewater and waste are generated during preparation, so that the pollution to the water and the environment can be greatly reduced.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for dyeing wool and silk blended fabrics. Background technique [0002] Wool, also known as wool, is a general term for fabrics woven with various wool and cashmere. Wool-viscose blended combed wool is a traditional combed wool product, which is comfortable and warm, and has a wide range of applications, but the viscose fiber has a general luster. , Wet strength is low, and the elasticity is average, which reduces the grade of the fabric. Generally, blending silk and wool can make up for the airtightness of ordinary wool fabrics, so that silk and wool blended clothes have the advantages of both silk fibers and wool fibers, and can be used to make high-end clothing and home textiles. [0003] The chemical and physical structures of silk fiber and wool fiber are different, and the dyeing properties of weak acid dyes are very different. The initial dyeing rate of wool fiber...
