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] The existing reactive black dye color matching products still have problems such as poor dyeing depth, low dyeing rate and color fixation rate, and difficult cleaning of dyed fabrics in the actual application process, such as patents CN102245712, CN1730566, etc.
This is due to the high concentration of dyes us

Abstract

The invention provides an active black dye composition, which comprises 45-90 weight parts of at least a component shown as a formula (I), 1-30 weight parts of at least a component B shown as a formula (II), and 1-40 weight parts of at least as a component C shown as a formula (III) and / or 1-40 weight parts of at least a component D shown as a formula (IV). The reactive black dye composition provided by the invention can be used for textile printing and dyeing, has advantages of good promotion performance, strong salt tolerance, easiness for washing and excellent wet-processing fastness, and is a rare economical black dye.

Description

(1) Technical field [0001] The invention relates to a reactive dye composition, in particular to a reactive black dye composition with excellent lifting power, easy water washing and stable dyeing performance. (2) Background technology [0002] In cotton fiber dyeing, black accounts for almost 40-50%, and 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] The existing reactive black dye color matching products still have problems such as poor dyeing depth, low dyeing rate and color fixation rate, and difficult cleaning of dyed fabrics in the actual application process, such as patents CN102245712, CN1730566, etc. This is...
