Problems solved by technology

[0002] Conventional disperse gray dyes are generally composed of C.I. disperse blue 56, C.I. disperse red 60, and C.I. disperse yellow 23. However, since C.I. disperse yellow 23 is listed as 24 banned azo dyes, C.I. Disperse Red 60 and C.I. Disperse Yellow 54 are gray disperse dyes compounded. However, due to the high cost of the compounded dyes, the dye lifting effect is inconsistent and the synchronization is poor, resulting in a large head-to-tail color difference during dyeing, which brings certain problems for printing and dyeing. difficulty

Embodiment 1

[0050] Add 20 grams of formula (I) component A, 54 grams of formula (II) component B, 26 grams of formula (III) component C, 200 grams of lignin 83A, 200 grams of diffusing agent MF, add 700 grams of water and stir well, Grind and disperse and dry to obtain gray disperse dyes.

Embodiment 2-10

[0062] According to the composition formula in Table 2, the gray disperse dye was made through stirring, grinding and drying. Wherein the moisture weight in Table 2 is the moisture weight of final gray disperse dye.

[0063] Table 2:

[0064]

[0065] The gray disperse dye of embodiment 2-10 is carried out performance test with the same method, compared with comparative example 1, the dyeing intensity of the gray disperse dye of embodiment 2-10 is high more than 3%, sublimation fastness reaches 4 grades, compatibility The performance reaches A-B level, and the cost is more than 3% lower.

Abstract

The invention relates to a grey disperse dye compound, disperse dye and a preparation method and usage of the disperse dye. The disperse dye is suitable for dyeing and printing of polyester and polyester blended fabrics.

Description

technical field [0001] The invention relates to a gray disperse dye composition, a disperse dye and a preparation method and application thereof. The disperse dye is suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] Conventional disperse gray dyes are generally composed of C.I. disperse blue 56, C.I. disperse red 60, and C.I. disperse yellow 23. However, since C.I. disperse yellow 23 is listed as 24 banned azo dyes, C.I. Disperse Red 60 and C.I. Disperse Yellow 54 are gray disperse dyes compounded. However, due to the high cost of the compounded dyes, the dye lifting effect is inconsistent and the synchronization is poor, resulting in a large head-to-tail color difference during dyeing, which brings certain problems for printing and dyeing. difficulty. How to provide an environmentally friendly dye with a wide range of pH values, consistent synchronization, good sublimation fastness, and relatively economical efficiency is an...
