Embodiment 1

[0014] (1) Put the wool and silk blended fabric, alum and alizarin into a water bath and dye it. The temperature of the water bath is set at 35°C, then add sodium sulfate and sodium bicarbonate into the water bath and continue dyeing;

[0015] (2) Take out the dyed wool and silk blended fabric and put it into another water bath, set the temperature of the water bath at 90°C, add acid red and sodium sulfate and dye it, cool it at 40°C and add sodium carbonate to solidify it. Color, take out to get red wool and silk blended fabric.

Embodiment 2

[0017] (1) Put the wool and silk blended fabric, alum and alizarin into a water bath and dye it. The temperature of the water bath is set at 40°C, then add sodium sulfate and sodium bicarbonate into the water bath and continue dyeing;

[0018] (2) Take out the dyed wool and silk blended fabric and put it into another water bath, set the temperature of the water bath to 95°C, add acid red and sodium sulfate and dye it, cool it at 40°C and add sodium carbonate to solidify it. Color, take out to get red wool and silk blended fabric.

Embodiment 3

[0020] (1) Put the wool and silk blended fabric, alum and alizarin into a water bath and dye it. The temperature of the water bath is set at 20°C, then add sodium sulfate and sodium bicarbonate into the water bath and continue dyeing;

[0021] (2) Take out the dyed wool and silk blended fabric and put it into another water bath, set the temperature of the water bath to 95°C, add acid red and sodium sulfate and dye it, cool it at 40°C and add sodium carbonate to solidify it. Color, take out to get red wool and silk blended fabric.

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

Abstract

The invention discloses a wool and silk blended fabric dyeing method which comprises the following steps of: dyeing a wool and silk blended fabric, alum and alizarine in a water bath kettle at 20-40 DEG C, adding sodium sulfate and sodium bicarbonate to the water bath kettle for dyeing continuously; dyeing the dyed wool and silk blended fabric, which is taken out of the water bath kettle before, in another water bath kettle at 90-95 DEG C with acid red and anhydrous sodium sulfate, cooling the wool and silk blended fabric, and adding sodium carbonate to the water bath kettle for fixation of the wool and silk blended fabric, thus obtaining a red wool and silk blended fabric which is taken out of the water bath kettle. In the mode, the wool and silk blended fabric dyeing method adopts a homochromy dyeing technology to dye the wool and silk blended fabric, and thus the blended fabric has a high homochromy property and is hardly damaged; the dye is firmly attached to the blended fabric, and thus the blended fabric is not discolored under exposure to the sun; and a small quantity of wastewater and scraps are generated in the preparation process, and thus the pollution to water quality and environment is greatly alleviated.

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 fabrics and wool knitwear use animal hair as the main component, and the blended fabrics obtained have the function of thick and warm. However, in recent years, people are no longer limited to woolen fabrics and wool knitwear, and will be blended with other fibers, increasing The design and color varieties of blended fabrics are improved, and the fabrics become lighter and thinner. Silk fabrics are easy to wrinkle and draw, and because of the high price of individual silk products, it is usually possible to blend silk with cashmere and wool to obtain high-grade textiles with excellent performance. [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 is slow, ...
