Embodiment 1

[0062] Add 70 grams of component A shown in formula (1), 30 grams of component B shown in formula (2-1), and 30 grams of dispersant CNF into 520 grams of water, and then grind and disperse with a sand mill to make a slurry , Or further spray drying to obtain yellow disperse dye.

[0063] The yellow disperse dye of Example 1 was tested for performance.

[0064] The specific test method is as follows:

[0065] Weigh 0.5 g of the yellow disperse dye of Example 1 and the commercially available C.I. Disperse Yellow 23 into 500 ml of water to prepare a disperse dye suspension. Mix 40ml of disperse dye suspension with 60ml of water, adjust the pH of the dye bath to 5 with acetic acid, and then raise the temperature to 60°C. At the same time, put 10 grams of polyester fiber into each for high-temperature and high-pressure dyeing. The temperature is raised to 130°C in 35 minutes. Keep the temperature for 45 minutes and cool to 80°C for sampling.

[0066] Observe the color of the cloth sample...

Embodiment 2-9

[0068] According to the composition formula in Table 1, a yellow disperse dye was prepared.

[0069] Table 1:

[0070]

[0071] The performance test of the yellow disperse dyes of Examples 2-9 was carried out using the same test method as that of Example 1, and the specific data are shown in Table 2.

[0072] Table 2: Unit: Level

[0073] name Sublimation fastness Washing fastness Rubbing fastness Example 13-44-55 Example 2455 Example 33-44-55 Example 4455 Example 5455 Example 6455 Example 7455 Example 8455 Example 9455 C.I. Disperse Yellow 23 344-5

[0074] It can be seen from Table 2 that the sublimation fastness, washing fastness and rubbing fastness of the yellow disperse dyes of Examples 1-9 are better than C.I. Disperse Yellow 23.

Abstract

The invention relates to a yellow disperse dye combination, disperse dye and a preparation method and application of the disperse dye. The disperse dye is suitable for dyeing and printing of dacron and blended fabrics of the dacron.

Description

Technical field [0001] The invention relates to a yellow disperse dye composition, a disperse dye, and a preparation method and application thereof. The disperse dye is suitable for dyeing and printing of polyester and its blended fabric. Background technique [0002] The traditional CI Disperse Yellow 23#, because of its affordable price and excellent performance, has been recognized by the majority of users and has a certain share in the market. However, because CI Disperse Yellow 23# is diazotized with phenol The dye obtained by coupling. In recent years, with increasing attention to environmental issues, p-aminoazobenzene has been listed as one of the 24 prohibited azo dyes. In the face of huge market demand, various companies have successively introduced alternative products, but so far, there has not been a substitute that can take both price and performance into consideration. Summary of the invention [0003] The problem to be solved by the invention [0004] The inventi...
