Embodiment 1

[0047] Component A shown in 26 grams of formula (1-1), component B shown in 31 grams of formula (2), component C shown in 18 grams of formula (3-1), 25 grams of formula (4- 1) The components D shown are mixed, crushed with a pulverizer, and mixed to obtain the disperse gray dye composition of the present invention.

[0048] 50 grams of the disperse gray dye composition of the present invention, 300 grams of dispersant MF and 300 grams of water are micronized with a sand mill (for dispersion treatment), and then spray-dried to obtain a solid dye product of the disperse gray dye composition. Based on the disperse gray dye composition used: the mass fraction of component A shown in formula (1-1) is 26%, the mass fraction of component B shown in formula (2) is 31%, and the mass fraction of component C shown in formula (3) The fraction is 18%, and the mass fraction of component D shown in formula (4) is 25%.

Embodiment 2～5

[0050] According to the dosage shown in Table 1, Component A, Component B, Component C, Component D, auxiliary agent, synergist and 200 grams of water are ground and dispersed with a sand mill, and then spray-dried to prepare Solid dye preparations for disperse dye compositions.

Embodiment 6

[0067] Imitate the phenomenon of cylinder blockage during dyeing, stop the machine during the dyeing process, and then heat up the dyeing after cooling down.

[0068] Experimental equipment: overflow double-cylinder mid-sample test machine

[0069] Normal dyeing: Weigh 1.226kg of white embryo polyester fiber, install it in the sample tank, put 12.3L of water, 5.4g of disperse dye in the machine tank, and add 18g of 0.5g / L glacial acetic acid. Raise the temperature at 3°C / min to 130°C, keep the temperature for 60 minutes, cool down and take samples. Described disperse dye is respectively with the dye product made in embodiment 1, the dye product made in comparative example 3, makes normal dyed cloth sample.

[0070] Shutdown of the tank during simulated dyeing: Weigh 0.68kg of white embryo polyester fiber and install it in the sample tank. Put 12.3L of water, 5.4g of disperse dye into the machine tank, and add 12.26g of 10g / L glacial acetic acid. Raise the temperature at 3°C / ...

Abstract

The invention discloses a disperse grey dye composition, and belongs to the technical field of disperse dye compositions. The composition is characterized by comprising the following components in percentage by weight: a component A which is one or more of compounds shown as a formula (1-1), a formula (1-2), a formula (1-3) and a formula (1-4); a component B which is a compound as shown in a formula (2); a component C which is a compound as shown in a formula (3); and a component D which is one or more of compounds as shown in a formula (4). Compared with common disperse grey dye compositions, the disperse grey dye composition disclosed by the invention is high in coloring consistency and good in compatibility in a dyeing process, does not generate dyeing defects even if dyeing interruption is caused by a failure in the dyeing process, and is particularly suitable for a short-process rapid dyeing process.

Description

technical field [0001] The invention relates to a disperse gray dye composition, more specifically to a disperse gray dye composition, a dye product containing the composition, and an application. Background technique [0002] As we all know, different from single-component dyes, due to the different chemical structures and performances of each component dye in the dyeing process, there will be differences in dyeing rate and dye exhaustion rate in the dyeing process. In the process of large-scale production Stricter process control is required, resulting in prolonged working hours, increased costs, low success rate of one-time dyeing, and large batch difference. At present, there is no gray black with good performance in disperse dyes, and the dye component is a single chemical structure. Commercial disperse grays are almost all dye compositions compounded and blended with various components, and these components have characteristics of very different hues. The gray color ...
