Embodiment 1

[0027] A kind of dyeing method that improves the disperse dye color fastness of polyester fabric, comprises the steps:

[0028] (1) Polyester fiber pretreatment:

[0029] a. Immerse the polyester fabric in the treatment solution, and then immerse the ultrasonic probe in the treatment solution. After 19 minutes of ultrasonic treatment at a specific frequency, filter out the polyester fabric, wash it in purified water, and dry it for later use;

[0030] b. Place the polyester fabric treated with the treatment liquid in operation a in a plasma generator for cold plasma treatment, and take it out for use after the treatment is completed;

[0031] (2) Dyeing:

[0032] Immerse the polyester fabric pretreated in step (1) in the dyeing solution, adjust the pH to 5, then raise the temperature in the dyeing solution to 60°C at a rate of 2°C / min, connect the DC magnetic field, and keep the magnetic field strength constant. Immerse the ultrasonic probe in the dyeing solution, and after ...

Abstract

The invention belongs to the technical field of polyester dyeing and discloses a dyeing method for improving disperse dye color fastness of polyester fabrics. The dyeing method includes steps: (1) polyester fiber pretreatment; (2) dyeing; (3) dyeing aftertreatment. The polyester fabrics dyed according to the dyeing method are high in dyeing depth and dye utilization rate, the dyed fabrics are excellent in color fastness, dyeing effects of different primary color dyestuffs are equalized, and popularization and application are benefited.

Description

technical field [0001] The invention belongs to the technical field of polyester dyeing, and in particular relates to a dyeing method for improving the dyeing fastness of disperse dyes of polyester fabrics. Background technique [0002] Polyester is a synthetic fiber with the highest output, the fastest development and the widest application. Its fiber fabrics are widely used in clothing, curtains, curtains, bedding and other fields. It has good elasticity, high strength, wear resistance, corrosion resistance, No insects and other advantages. Polyester fiber is the most used chemical fiber in textile fibers, and it is usually dyed with disperse dyes. Disperse dyes have the characteristics of small molecules, weak polarity, insoluble in water, and good compatibility with polyester fibers. They can be "solid-dissolved" in the amorphous region of fibers, but no chemical bonds occur. Therefore, during storage, washing, heat setting, etc., the dye molecules on the fabric are ea...
