Abstract

The invention discloses a composite active brilliant orange dye composition. The active ingredients mainly comprise alkali metal salt of dye I and alkali metal salt of dye II, wherein the molar ratio of the two ingredients is (1-5):(3-7). The composite active orange dye disclosed by the invention is synthesized by a mixing structure using a one-step method; the obtained composite-structure product has high solubility which reaches 280g / l at 2 DEG C and bright color light, and the dyeing is improved; and the composite active orange dye can be applied to extra dark printing. Conventional printing is realized, and the composite active orange dye also can be applied to the printing equipment adopting an automatic size mixing system.

Description

technical field

[0001] The invention belongs to the technical field of dyes, and relates to a novel composite reactive brilliant orange dye and a manufacturing method thereof. Background technique

[0002] Reactive Orange P-2R (C.I Reactive Orange 13) is often used in the printing of cellulose fibers due to its bright color, but it also has some defects, mainly due to the low color fixation rate of the dye, which is not conducive to dyeing dark colors. At the same time, the solubility at low temperature is poor. Under certain conditions, the solubility is less than 100g / l, which cannot meet the technical requirements of printing equipment using an automatic pulping system. Contents of the invention

[0003] The purpose of the present invention is to provide a new type of composite reactive orange dye in view of the current printing and dyeing industry's high fixation rate, high solubility, strong process applicability, energy saving and environmental protection requirement...
