preparation example Construction

[0047] On the other hand, the present application also provides a preparation method of the disperse dye described in the present application, which is characterized in that it comprises: mixing the components contained in the disperse black dye composition described in the present application according to the stated ratio to prepare Disperse black dye composition, which is ground (micronized) in the presence of auxiliary materials, optionally dried, preferably spray-dried;

[0048] Alternatively, each component contained in the disperse black dye composition described in this application is ground separately in the presence of auxiliary materials, then mixed according to the stated ratio, and optionally dried, preferably spray-dried.

[0049] The disperse black dye composition of the present application or its components can be liquid or paste after grinding (micronization), and can be powder or granular after drying (preferably spray drying).

[0050]In another aspect, the p...

Embodiment

[0054] The present application will be further described below in conjunction with the examples, but the protection scope of the present application is not limited thereto.

[0055] In the embodiment, the component A, component B and component C of the present application are mixed with dispersant MF, diffusing agent NNO, diffusing agent CNF or sodium lignosulfonate 85A or 83A in a certain ratio, and then used Grinding and dispersing by sand milling to make slurry, and further spray drying to make disperse dyes.

[0056] The above-mentioned dye components are all known dye compounds and are commercially available. Dispersant MF, diffusing agent NNO, diffusing agent CNF, sodium lignosulfonate 85A and 83A are all known auxiliaries and can be purchased in the market.

[0057] Examples 1-16 Mix component A, component B, component C, additives and water according to the ratio shown in Table 1, grind and spray dry to prepare disperse dyes.

[0058] Table 1

[0059]

Embodiment 1

[0065] Take 43g of the compound of the following formula (III-1), 22g of the compound of the following formula (4), 1g of the compound of the following formula (5), mix and grind with 41.5g of lignin MF and 161g of water, and spray dry to prepare a disperse dye.

[0066]

[0067]

[0068] Use respectively 0.1g of the disperse dyes prepared in Examples 1-16 and Comparative Examples 1-2, mix with 10g of polyester ammonia and 99.9g of water, adjust the pH of the dye bath to 5 with acetic acid, and heat up to 5 in 35 minutes. 210°C, keep warm for 30 minutes, cool to 80°C, take it out, dye according to GB / T2394-2006 standard to obtain black textile material, and then carry out setting treatment at 190°C for 45 seconds. Using GB / T5718-1997 to measure its sublimation fastness, the results are as follows.

Abstract

The invention provides a disperse dye as well as a preparation method and an application thereof and a disperse black dye composition with high sublimation fastness. The disperse dye comprises the composition. Based on the total weight of the composition, the composition comprises 30-50wt% of component A in the formula (I) in the specification, 35-70wt% of component B in the formula (II) in the specification and 0-15wt% of component C in the formula (III) in the specification, wherein in the formulas, R1 is Cl or Br; R2 and R3 are respectively and independently -CH2CH2OCOCH3 or -CH2COOCH3; Q is shown in the structural formula in the specification; X1 is Cl or Br; R4 is H, -NHCOR7 or C1-C4 alkyl; R5 and R6 are respectively and independently C1-C4 alkyl, C1-C4 alkyl with one hydrogen replaced by cyano group or -CH2CH2OCOCH3; and R7 is C1-C4 alkyl.

Description

technical field [0001] The application relates to a disperse black dye composition with high sublimation fastness, a disperse dye containing the composition and its preparation method and application. The disperse dye is suitable for dyeing blended fabrics such as polyester fiber, polyester spandex or polyester cotton and printing. Background technique [0002] With the rapid development of the dye industry, people have higher and higher requirements for the application performance of dyes, and excellent fastness is the basic performance required by customers. At present, there is a great demand for disperse black dyes in the market. Traditional disperse black dyes such as disperse black ECO are widely used, but the sublimation fastness is average. Therefore, in order to meet the needs of customers, it is urgent to develop dyes with better sublimation fastness for dyeing and printing of blended fabrics such as polyester fiber, polyester spandex or polyester cotton. Conten...
