Abstract

The invention provides a reactive black dye composition which comprises 30-85 parts by weight of ingredient A, 1-40 parts by weight of ingredient B, 5-50 parts by weight of ingredient C, 1-40 parts byweight of ingredient D and 0--40 parts by weight of ingredient E, wherein the ingredient A is at least one of compounds shown as formula (1) as shown in the specification; the ingredient B is at least one of compounds shown as formula (2) as shown in the specification; the ingredient C is at least one of compounds shown as formula (3) as shown in the specification; the ingredient D is at least one of compounds shown as formula (4) as shown in the specification; and the ingredient E is at least one of compounds shown as formula (5) as shown in the specification. When the reactive black dye composition is used for fabric printing and dyeing, the composition has a good deep dyeing property, and various excellent color fastnesses, particularly outstanding fastness to water washing and rubbing.

Description

(1) Technical field [0001] The invention relates to a reactive black dye composition, in particular to a reactive black dye composition suitable for printing and dyeing cellulose fibers or materials containing cellulose fibers. (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 there are also defects such as poor lifting force and insufficient blackness, which limit its wide use. [0003] The prior art appears to use reactive black KN-B as the main color matching to obtain reactive black dyes, and its dyeing performance is improved, such as patents CN101143972A, CN1861694A and CN1524904A, etc., but these products are still fast to washing and fastness to rubbing. There is room for further improvement. (3) Contents of...
