Problems solved by technology

But at the same time, there are also defects such as poor lifting force and insufficient blackness, which limit its wide use.
[0003] In the prior art, reactive navy blue or black dyes are obtained through color matching based on reactive black KN-B, and the dyeing performance is improved, but these products still have weak dyeing depth, dyeing rate and color fixation in the actual application process. Low efficiency, dyed fabrics are not easy to clean, etc., such as patent CN103342901A and patent CN103627208A, etc.

Embodiment 1

[0084] Mechanically mix 90 parts of the dye compound represented by formula (I-1), 10 parts of the dye compound represented by formula (II-1) and 15 parts of sodium sulfate, and the obtained dye product dyes cotton in navy blue.

[0085]

Embodiment 2

[0087] With 58 parts of dye compounds shown in formula (I-1), 8 parts of dye compounds shown in formula (II-1), 19 parts of dye compounds shown in formula (III-1), 15 parts of formula (IV-1 ) The dye compound shown in ) and 10 parts of sodium sulfate are mechanically mixed, and the dye product dyed cotton obtained is black.

[0088]

Embodiment 3～50

[0090] Mechanically mix the dyestuffs listed in Table 1 to dye cotton from navy blue to black:

[0091] Table 1

[0092]

[0093]

[0094]

[0095] Dyeing example:

[0096]Add the dye products obtained in Examples 1 to 50 respectively to the dyeing bath containing 60g / L sodium sulfate (dye concentration 2.0%, bath ratio 1:25), and the temperature is raised to 60°C at 2°C / min. Cotton fabrics were dyed for 30 minutes, added soda ash to make the concentration 15g / L, and dyed at this temperature for 45 minutes, then washed the dyed matter, soaped with non-ionic detergent for 15 minutes, rinsed and dried. Test its color fastness to washing and rubbing according to the methods determined in GB / T3921-2008 and GB / T3920-2008 respectively, and the results are as follows:

[0097] Washing fastness: fading ≥ 4 ~ 5 grades, cotton staining ≥ 4 ~ 5 grades, nylon staining ≥ 4 ~ 5 grades, polyester staining ≥ 4 ~ 5 grades;

[0098] Rubbing fastness: dry rubbing ≥ 4 to 5 grades; wet...

Abstract

The invention discloses an activated dark blue to black dye compositioncombination and a dye product. The dye compositioncombination comprises a component A, a component B and a component C, wherein the component A is selected from at least one compound as shown in formula (I); the component B is selected from at least one compound as shown in formula (II); the component C is selected from at least one compound as shown in formula (III) and/or formula (IV); the quantity of the parts by weight of the component A is 1 to 99; the quantity of the parts by weight of the component B is 1 to 99; the quantity of the parts by weight of the component C is 0 to 50. The dye product comprises the dye compositioncombination. The dye compositioncombination and the dye product are good in deep dyeing property, excellent in promoting capacity, high in dyeing rate and fixation rate, good in compatibility, and excellent in color fastness, small in use level, easy to wash and clear in residual liquor during printing and dyeing process, stable in dyeing property, and applicable to technologies of dip dyeing, pad dyeing and , printing and the like.

Description

(1) Technical field [0001] The invention relates to a reactive navy blue to black dye composition and a dye product suitable for printing and dyeing of cellulose fibers or materials containing cellulose fibers. (2) Background technology [0002] Among reactive dyes, navy blue to black dyes are used in the largest amount, among which more direct dyes and sulfur dyes are banned and restricted due to environmental protection issues. Reactive black KN-B is used in a large amount because of its low price, good fastness, high color fixation rate and easy washing, and there is no environmental protection problem including AOX. But there are also defects such as poor lifting force and insufficient blackness, which limit its wide use. [0003] In the prior art, reactive navy blue or black dyes are mainly obtained through color matching based on reactive black KN-B, and the dyeing performance is improved, but these products still have weak dyeing depth, dyeing rate and color fixation...
