Problems solved by technology

Liquid disperse dyes have been widely used, but because liquid disperse dyes are suspensions of disperse dyes in water, precipitation is prone to occur over time.
This brings certain difficulties to the subsequent dyeing.

preparation example Construction

[0038] The preparation method of red liquid disperse dye of the present invention comprises the following steps:

[0039] The component A, additives and water are mixed in proportion with a sand mill or grinder to make a red liquid disperse dye;

[0040] Or add half of the water, component A and additives in proportion to mix them with a sand mill or grinder, and then make up water in proportion to make red liquid disperse dyes.

Embodiment 1

[0046] Component A shown in 23 grams of formula (1), 5 grams of diffusion agent CNF, 1 gram of Pingpinga O and 1 gram of Turkish red oil are added to 70 grams of water, and ground and dispersed with a sand mill to make a red liquid disperse dye .

Embodiment 2-9

[0056] According to the composition formula in Table 1, red liquid disperse dye is made.

[0057] Table 1:

[0058]

[0059] The performance test of the red liquid disperse dyes in Examples 2-9 was carried out using the same test method as in Example 1, and the specific data are shown in Table 2.

[0060] Table 2:

[0061] name

[0062] As can be seen from Table 2, compared with Comparative Example 1-2, the red liquid disperse dyes of Examples 1-9 have a longer precipitation time, which brings great convenience for transportation and use. And the red liquid disperse dye of embodiment 1-9 is compared with comparative example 1-2 and red powdery dye, dyed foot water chromaticity is light, COD is low, more environmental protection.

Abstract

The invention relates to red liquid disperse dye and a preparation method and application of the red liquid disperse dye. The red liquid disperse dye is suitable for dyeing and printing of dacron and blended fabrics of the dacron, and is especially suitable for the automatic production process of dyeing the dacron and the blended fabrics of the dacron.

Description

technical field [0001] The invention relates to a red liquid disperse dye and its preparation method and application. The red liquid disperse dye is suitable for dyeing and printing of polyester and its blended fabrics, especially for the automatic production process of polyester and its blended fabrics dyeing. Background technique [0002] Conventional powdery disperse dyes need to be sprayed dry, so they need a large amount of dispersant to wrap, and the dispersant is not dyed on the cloth during dyeing, but is discharged as waste water, which adds a serious burden to the downstream printing and dyeing industry. [0003] Moreover, the dust of powdery and granular disperse dyes is also a big problem. When dyeing, the powdery and granular disperse dyes need to be beaten into liquid before dyeing, which not only increases the workload of workers, but also brings certain negative effects on the health of workers. [0004] As the cost of the current labor market increases, mor...
