Problems solved by technology

[0002] With the rapid development of polyester fiber in recent years and the improvement of people's requirements for textiles, correspondingly higher requirements have been put forward for the dyeing performance and environmental protection performance of the dye itself, especially the complicated discharge printing process, which is prone to defects and relatively high cost. High, but the pattern printed by discharge dyeing is more delicate than that of resist dyeing, the outline is clear, and the edge is not white, the effect is better
Discharge printed fabrics are rich in color and fine in pattern, but the cost is high, the production process is long and complicated, and the equipment occupies a large area, so it is mostly used for high-end printed fabrics

Embodiment 1

[0018] Based on the total mass of the disperse black pullable dye mixture, each component is weighed according to the ratio of 40% disperse black pullable dye and 60% dispersant in mass percentage, wherein the disperse black pullable dye consists of 40% compound A, 40% of compound B, and 20% of compound C. The dispersant is composed of sodium methylnaphthalenesulfonate formaldehyde condensate and sodium lignosulfonate in a mass ratio of 3:7. After the above materials are mixed evenly, add water to grind, and the slurry obtained by grinding is spray-dried. The process conditions of spray-drying are: the inlet temperature is 120°C, the outlet temperature is 50°C, and after drying, a dispersed and removable black dye with a particle size of 1 μm is obtained. mixture.

[0019]

Embodiment 2

[0021] Compared with Example 1, the present embodiment is different in that: the disperse black dye mixture is made up of 88% disperse black dye and 12% dispersant, and the dispersant consists of sodium methylnaphthalenesulfonate formaldehyde condensate It is compounded with sodium lignosulfonate at a mass ratio of 2:3, and the rest are identical, so they will not be described here.

Embodiment 3

[0023] Compared with Example 1, the present embodiment differs in that: the disperse black dye mixture is made up of 90% disperse black dye and 10% dispersant, and the dispersant consists of sodium methylnaphthalenesulfonate formaldehyde condensate It is compounded with sodium lignosulfonate at a mass ratio of 10:21, and the rest are identical, so details are not repeated here.

Abstract

The invention discloses a disperse pullable black dye mixture, which is composed of disperse black pullable dye with a mass percentage of 40-90% and the rest of a dispersant, based on the total mass of the disperse pullable black dye mixture. Wherein, the disperse black pull out dyestuff is made up of following mass percent: 40~60% compound A, 17~40% compound B, 20~27% compound C, the structural formula of compound A, B, C is respectively as formula ( Ⅰ), (II), and (Ⅲ): The dispersible dischargeable black dye mixture of the invention has a reasonable formula, has good application performance in all aspects of discharge property, can obtain good discharge effect when applied to printing, and has excellent fastness properties when applied to dyeing. The invention also discloses a preparation method of the disperse pullable black dye mixture. The granular dye mixture is obtained after mixing the raw materials, adding water, grinding and spray drying. The process steps are simple, the operability is strong, and it is suitable for industrial production.

Description

technical field [0001] The invention relates to a dye mixture, in particular to a disperse pullable black dye mixture and its preparation method and application. Background technique [0002] With the rapid development of polyester fiber in recent years and the improvement of people's requirements for textiles, correspondingly higher requirements have been put forward for the dyeing performance and environmental protection performance of the dye itself, especially the complicated discharge printing process, which is prone to defects and relatively high cost. High, but the pattern printed by discharge dyeing is more delicate than that of resist dyeing, the outline is clear, and the edge is not white, so the effect is better. Discharge printed fabrics have full color and fine patterns, but the cost is high, the production process is long and complicated, and the equipment occupies a large area, so it is mostly used for high-end printed fabrics. Discharge printing has attracte...
