Problems solved by technology

But it also has defects such as poor lifting force and insufficient blackness, which limit its wide use.
[0003] In the prior art, reactive black KN-B is mainly used for color matching to obtain reactive black dyes, and its dyeing performance is improved. However, these products still have problems such as low coloring strength and large amount of dyes during use in the actual application process. Such as patent CN1746230A and patent CN1745147A, etc.

Embodiment 1

[0087] Mechanically mix 60 parts of the dye compound of formula (I-1), 18 parts of the dye compound of formula (II-1), 22 parts of the dye compound of formula (III-1) and 15 parts of sodium sulfate, and obtain the dye dye Cotton is black.

[0088]

Embodiment 2

[0090] Mechanically mix 65 parts of the dye compound of formula (I-2), 15 parts of the dye compound of formula (II-2), 20 parts of the dye compound of formula (III-2) and 10 parts of sodium sulfate, and obtain the dye dye Cotton is black.

[0091]

Embodiment 3～50

[0093] Mechanically mix the dyestuffs listed in Table 1 to dye cotton black:

[0094]

[0095]

[0096]

[0097] Dyeing example:

[0098]Add the dye composition that embodiment 1~50 obtains respectively in the dye bath that contains 60g / L sodium sulfate (dye concentration 2.0%, bath ratio 1:25), with 2 DEG C / min the temperature is raised to 60 DEG C, Dye the cotton fabric for 30 minutes, add 15g / L soda ash, and dye at this temperature for 60 minutes, then rinse the dyed matter, soap it with non-ionic detergent for 15 minutes, rinse and dry. 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:

[0099] Washing fastness: fading ≥ 4 ~ 5 grades, cotton staining ≥ 3 ~ 4 grades, nylon staining ≥ 3 ~ 4 grades, polyester staining ≥ 4 ~ 5 grades;

[0100] Rubbing fastness: dry rubbing ≥ 4 to 5 grades; wet rubbing ≥ 4 grades.

Abstract

The invention discloses poly-azo reactive black dye composition, a dye product and an application of the dye product. The poly-azo reactive black dye composition comprises a component A, a component B and a component C, wherein the component A is selected from at least one of compounds (I), the component B is selected from at least one of compounds (II), the component C is selected from at least one of compounds (III), G1 and G2 are independent of each other and do not adopt the structure shown in the formula (i) or formula (ii) simultaneously, G3 and G4 are independent of each other and do not adopt the structure shown in the formula (iii) or formula (iv) simultaneously, and G5 and G6 are independent of each other and do not adopt the structure shown in the formula (v) or formula (vi) simultaneously. The reactive black dye product contains the poly-azo reactive black dye composition. The invention further provides the application of the dye product to printing and dyeing of materials containing cellulose fibers and / or polyamide fibers.

Description

(1) Technical field [0001] The invention relates to a polyazo reactive black dye composition, a dye product and its application, especially the application in printing and dyeing of materials containing cellulose fiber and / or polyamide fiber. (2) Background technology [0002] Among reactive dyes, dark dyes are used in large amounts, especially black reactive dyes. Reactive black KN-B has low price, good fastness, high color fixation rate and easy washing, and there is no AOX Environmental protection issues, so the amount is relatively large. But it also has defects such as poor lifting force and insufficient blackness, which limit its wide use. [0003] In the prior art, reactive black KN-B is mainly used for color matching to obtain reactive black dyes, and its dyeing performance is improved. However, in the actual application process of these products, there are still problems such as low coloring strength and large amount of dyes used during use. Such as patent CN17462...
