Abstract
The invention relates to the field of active dye in a novel material technology, and particularly relates to composite active black dye. The composite active black dye is formed by mixing active dye A, active dye B, active dye C and active dye D, wherein the weight percent of the four active dye is as follows: the dye A accounts for 5 to 70 percent; the dye B accounts for 5 to 70 percent; the dye C accounts for 5 to 20 percent; the dye D accounts for 5 to 30 percent. The dye provided by the invention is not only good in compatibility and easy to wash, but also relatively high in fixation rate; the absolute fixation rate of the composite active black dye reaches up to 80 to 85 percent; the dying residual liquid can be reduced by 30 to 40 percent under the same condition.
Description
Technical field
The present invention relates to the reactive dyestuff field in new material technology, particularly a kind of compound reactive black dye.
Background technology
Reactive dyestuffs are as the representative of modern dyestuffs industries, and immediate and mid-term obtains fast development.At present, Reactive Dye for Cellulose Fibre annual production reaches about 250,000 tons in the world, accounts for 20% of world's dyestuff annual production.Active black dye applies more, that consumption is maximum look kind in dyestuff.In view of at present conventional reactive black dye kind (such as: reactive black WNN) is when exhaust dyeing, its absolute fixation rate is not high, and unstable, generally only has 65-70%.Thus it is inadequate to result in its dye stability, front and back aberration is comparatively large, and when factory uses, one-time success rate is not high, do over again, modify more.Because the absolute fixation rate of reactive black dye is not high, result also in its dyeing residual liquid COD very high.
Summary of the invention
The invention provides and a kind ofly not only have good compatibleness and easy detergency, and have higher fixation rate, its absolute fixation rate is up to 80-85%, and dyeing residual liquid can reduce the compound reactive black dye of 30-40% on year-on-year basis under condition simultaneously.
