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

[0037] The preparation method of yellow liquid disperse dye of the present invention may further comprise the steps:

[0038] The component A, additives and water are mixed in proportion with a sand mill or grinder to make a yellow liquid disperse dye;

[0039] Or add half of the water, component A and additives in proportion to mix with a sand mill or grinder, and then make up water in proportion to make a yellow liquid disperse dye.

Embodiment 1

[0045] Add 10 grams of component A shown in formula (1), 3.5 grams of diffusing agent CNF and 0.5 grams of Pingpinga O to 86 grams of water, grind and disperse with a sand mill to make a yellow liquid disperse dye.

Embodiment 2-9

[0055] According to the composition recipe in Table 1, a yellow liquid disperse dye was made.

[0056] Table 1

[0057]

[0058] The performance test of the yellow liquid disperse dyes in Examples 2-9 was carried out by the same test method as in Example 1, and the specific data are shown in Table 2.

[0059] Table 2: Unit: Grade

[0060]

[0061] It can be seen from Table 2 that compared with Comparative Example 1-2, the yellow liquid disperse dyes of Examples 1-9 have prolonged precipitation time, which brings great convenience for transportation and use. And the yellow liquid disperse dye of embodiment 1-9 is compared with comparative example 1-2 and yellow powdery dye, dyed foot water chromaticity is light, COD is low, more environmental protection.

Abstract

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

Description

technical field [0001] The invention relates to a yellow liquid disperse dye and its preparation method and application. The yellow 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 increase...
