Problems solved by technology

[0009] However, after the above-mentioned three primary colors are compounded, the saturation, compatibility and dyeing performance of the color still need to be improved. For this, the patents CN1730565 and CN1730566 have selected other red components and yellow components to compound with the above-mentioned navy blue components. CN1912014 then achieves the purpose of improvement by changing the structure of the active navy blue component, and then compounding with the above-mentioned magenta component and orange-yellow component, but the dyeing performance of the above-mentioned compound dye is still not fully satisfactory, and the product cost is relatively high. High, not suitable for large-scale promotion and application, and its cost performance still needs to be further improved

Embodiment 1

[0050] The following dye compositions are provided:

[0051] Fuchsin dye component A15 grams, wherein weight percent, formula (I-1): formula (II-1): Yuanming powder (industrial sodium sulfate)=90: 10: 10;

[0052] Orange dye component B15 grams, wherein weight percentage, formula (III-1): formula (IV-1): Yuanming powder=92: 8: 15;

[0053] Navy blue dye component C70 grams, wherein weight percent, formula (V-1): Yuan Mingfen=85:15

[0054] Fully stir the dyes of each component according to the above ratio in the dry blending barrel, and mix the dry powder evenly. The black dye obtained is used for dyeing cotton fabrics, and has the properties of good blackness, level dyeing and color fastness.

Embodiment 2

[0056] The following dye compositions are provided:

[0057] Fuchsin dye component A10 grams, wherein weight percent, formula (I-1): formula (II-1): Yuan Mingfen=95: 5: 15;

[0058] Orange dye component B20 grams, wherein weight percent, formula (III-4): formula (IV-1): Yuanming powder=90: 10: 20;

[0059] Navy blue dye component C70 grams, wherein weight percent, formula (V-1): Yuan Mingfen=90:10;

[0060] With each component dyestuff of above-mentioned proportioning, 5 grams of diffusing agent naphthalenesulfonate formaldehyde condensate (NNO), add water to dissolve, stir evenly and dry, the black dyestuff that obtains is used for dyeing cotton fabric, has blackness good, uniform Good dyeing and color fastness properties.

Embodiment 3

[0062] The following dye compositions are provided:

[0063] Fuchsin dye component A10 grams, wherein weight percent, formula (I-1): formula (II-1)=95:5;

[0064] Orange dye component B15 grams, wherein weight percent, formula (III-1): formula (IV-1): Yuanming powder=90:10;

[0065] The navy blue dye component C75 gram of formula (V-4),

[0066] With the dyestuff of above-mentioned proportioning and 20 grams of sodium sulfate, 5 grams of dispersant MF (methylnaphthalenesulfonic acid formaldehyde condensate), after adding water to dissolve, stir evenly and dry, the black dyestuff that obtains is used for dyeing cotton fabric, has Good blackness, level dyeing and color fastness.

Abstract

The invention relates to active black dye which essentially comprises fuchsine component A, orange yellow component B and navy component C, and is based on the component A, the component B and the component C; the weight percentage of the component A is 1 to 25 percent, the weight percentage of the component B is 1 to 25 percent, and the weight percentage of the component C is 50 to 95 percent; and the component A comprises at least a dye shown as formula (I) and a dye shown as formula (II), the component B comprises at least a dye shown as formula (III) and a dye shown as formula (IV), and the component C comprises at least a dye shown as formula (V). The active black dye has the advantages of high product solubility, strong salt and alkali resistance, high uptake date and color fixing rate, excellent dyeing fastness and environmental protection.

Description

(1) Technical field [0001] The invention relates to a reactive black dye, in particular to a reactive and economical reactive black dye blended with three primary colors with high quality, low price, green and environmental protection. (2) Background technology [0002] Reactive dyes are widely used for their bright color, good color fastness, and are suitable for dyeing cellulose fibers. Among them, the three primary colors are used because the dyeing performance of each single-color component is close, the compatibility is good, and various shades that meet the requirements can be compounded. Highly respected, the common three primary colors in dyes are composed of reactive magenta, reactive orange, and reactive navy blue. The traditional classic three primary colors are as follows: [0003] Active Fuchsin Components: [0004] [0005] Active orange component: [0006] [0007] Active navy blue components: [0008] [0009] However, after the above-mentioned th...
