Embodiment 1
[0014] A dyeing process, comprising the steps of:
[0015] 1) Soak the fabric to be dyed in the dyeing accelerator for 2 minutes, and then perform ultrasonic treatment for 40 minutes;
[0016] 2) Add dye solution to step 1), the dyeing temperature is 30°C, and dye for 10 minutes;
[0017] 3) Add color-fixing agent to step 2), the amount of color-fixing agent added is 50g / L, and ultrasonic treatment is performed again for 10 min to complete the dyeing. Wherein said dye-accelerating agent is sodium sulfate, and said color-fixing agent is sodium carbonate.
Embodiment 2
[0019] A dyeing process, comprising the steps of:
[0020] 1) Soak the fabric to be dyed in the dyeing accelerator for 8 minutes, and then perform ultrasonic treatment for 20 minutes;
[0021] 2) Add the dye solution to step 1), the dyeing temperature is 20°C, and the dyeing time is 20 min;
[0022] 3) Add color-fixing agent to step 2), the amount of color-fixing agent added is 20g / L, and ultrasonic treatment is performed again for 20 minutes to complete the dyeing. Wherein said dye-accelerating agent is sodium sulfate, and said color-fixing agent is sodium carbonate.
Embodiment 3
[0024] A dyeing process, comprising the steps of:

Abstract
The invention discloses a dyeing process. The dyeing process comprises the following steps: 1) dipping a fabric to be dyed into a dyeing accelerant for soaking for 2-8min, and then performing ultrasonic treatment for 20-40min; 2) adding a dyeing solution into the step 1), and dyeing for 10-20min at the dyeing temperature of 20-30 DEG C; 3) adding a color fixing agent into the step 2), wherein the adding amount of the color fixing agent is 20-50g / L; further performing ultrasonic treatment for 10-20min to complete dyeing. The dyeing accelerant is sodium sulfate, and the color fixing agent is sodium carbonate. The invention provides the dyeing process, the dyeing temperature is low, the dyeing can be performed at the temperature of 20-30 DEG C which is close to normal temperature, and the damages to safety of operation workers caused by volatilization of a dyeing agent at high temperature can be avoided; in addition, according to the process disclosed by the invention, the ultrasonic treatment is particularly introduced, so that dye molecules can be significantly dispersed and better enter fabric fiber, and the color fastness is further improved; the process has the advantages of simplicity in operation and low cost.
Description
technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing process. Background technique [0002] With the pace of reform and opening up, while people's living standards are improving, their personalities are becoming more and more prominent, especially the younger generation, which has changed the shy tradition of the older generation, dressing more and more boldly, and color matching to show their individuality. Clothing colors are getting richer and richer. With the continuous advancement of printing and dyeing technology, more and more dyeing processes have been developed. Subtle changes in pH, temperature, inorganic salts and other conditions during the dyeing process will have a greater impact on the dyeing rate and color fastness. At present, various dyeing techniques generally have problems such as too long coloring time and high dyeing temperature, which cause the volatilization of dyes...
