Problems solved by technology

[0002] Pure polyester fabrics are generally dyed by high-temperature and high-pressure exhaust dyeing, which has the problems of long dyeing time, low production efficiency, large electricity and steam consumption, and high sewage discharge.
In addition, in the actual dyeing process, a large amount of dispersant and other auxiliary agents need to be added, resulting in serious chroma pollution and more COD emissions
Similarly, the adsorption and solubilization of the auxiliary agent on the fiber surface leads to the adsorption and solubilization of the dye on the fiber surface, and also leads to the accumulation of the dye on the fiber surface. With the help of complex post-washing, including reduction cleaning and soaping, etc., to fully remove these floating colors and give dyed fabrics sufficient color fastness performance, multiple post-washing will consume a lot of water, energy and a considerable amount of chemicals , causing serious pollution to the environment

Embodiment 1

[0022] (1) Mix disperse blue BGL disperse dye filter cake, anionic surfactant, nonionic surfactant and water and grind evenly to obtain a blue disperse dye slurry with a dye particle fineness of 0.75 μm; wherein the disperse dye filter The mass ratio of cake, anionic surfactant, and nonionic surfactant is 90:7:3, and an appropriate amount of water.

[0023] (2) Mix vegetable oil and water with a volume ratio of 7:3, add Tween 80 in an amount of 2% of the total mass concentration of vegetable oil and water, and stir at a rotating speed of 2000rmp to obtain an emulsified paste.

[0024] (3) Dilute the disperse blue BGL dye slurry obtained in step (1) with water, and add the emulsified paste and acrylic synthetic paste of step (2) to obtain disperse blue BGL liquid disperse dyes, wherein the emulsified paste and acrylic The solid contents of the synthetic pastes are respectively 0.5% and 0.5% of the total amount of the dye slurry.

[0025] (4) Add water to the disperse blue BGL ...

Embodiment 2

[0028] (1) Disperse yellow H3GL disperse dye filter cake, anionic surfactant, nonionic surfactant and water are mixed and ground evenly to obtain a disperse yellow H3GL dye slurry with a dye particle fineness of 0.85 μm, wherein the disperse dye filter The mass ratio of cake, anionic surfactant, and nonionic surfactant is 90:7:3, and an appropriate amount of water.

[0029] (2) Dilute the disperse yellow H3GL dye slurry obtained in step (1) with water, and add the emulsified paste and acrylic synthetic paste obtained in Example 1 step (2), to obtain yellow liquid disperse dyes, wherein the emulsified paste and The solid contents of the acrylic synthetic pastes are respectively 0.5% and 0.5% of the total amount of the dye slurry.

[0030] (3) Add water to the disperse yellow H3GL liquid disperse dye obtained in step (2) to obtain a disperse dye bath, wherein the volumes of liquid disperse dye and water are 20mL and 180mL; Dyeing in the dyeing bath, one dipping and one padding,...

Abstract

The invention relates to a washing-free continuous dyeing method for polyester fabrics with disperse dyes. The invention mixes disperse dyes, surfactants and water and grinds them uniformly to obtain disperse dye slurry; then dilutes with water, and adds emulsified paste and Thickening agent to obtain liquid disperse dyes; add water to obtain disperse dye dyeing baths, padding polyester fabrics for dyeing, then drying, and then baking to fix the color, and finally drop the cloth to cool, and the dyeing is completed. The dyeing process of the invention is simple, the chemicals used are ecological and environment-friendly, the production efficiency is high, no dyeing waste water is discharged, energy is saved, and the invention has important practical significance for energy saving and emission reduction. The dye uptake rate of the dyed product obtained by the present invention is higher than 95%, the chemical content on the fabric is not more than 3%, the dyed fabric does not need to be washed, and the dry and wet rubbing fastness and staining fastness can reach 4-5 grades. The color fastness to fading is grade 5, meeting the quality requirements for textile dyeing.

technical field [0001] The invention belongs to the technical field of textile dyeing, in particular to a washing-free continuous dyeing method for polyester fabric with disperse dyes. Background technique [0002] Pure polyester fabrics are generally dyed by high-temperature and high-pressure exhaust dyeing, which has the problems of long dyeing time, low production efficiency, large electricity and steam consumption, and high sewage discharge. In addition, in the actual dyeing process, it is necessary to add a large amount of auxiliary agents such as dispersants, resulting in serious chroma pollution and more COD emissions. Similarly, the adsorption and solubilization of the auxiliary agent on the fiber surface leads to the adsorption and solubilization of the dye on the fiber surface, and also leads to the accumulation of the dye on the fiber surface.
