High saline alkali reactive brilliant blue KN-RSR dye composition and preparation method thereof

Abstract

The invention discloses a high saline alkali reactive brilliant blue KN-RSR dye composition and a preparation method thereof, which belong to the technical field of reactive dyes, and solve the problem that reactive brilliant blue molecules are easily associated and hydrolyzed to separate out in the prior art. The high saline alkali reactive brilliant blue KN-RSR dye composition is a homogeneous mixture based on a complex synergism principle, and utilizes a supramolecular chemistry theory, so that the defect that the saline-alkaline resistance of reactive brilliant blue KN-RSR is poor under the condition of conventional dyeing is improved, meanwhile, the enhancement performance of dye is increased, and the dye composition has excellent leveling property and pile-onproperties; the high saline alkali reactive brilliant blue KN-RSR dye composition not only can be used for dyeing cheese and finished garment which have higher requirements on leveling property, but also can be applied in currently favored energy-saving and environment-protecting dyeing: cold padder dyeing.

Description

Technical field [0001] The invention relates to the technical field of reactive dyes, in particular to a high-salt basic reactive brilliant blue KN-RSR dye composition and a preparation method thereof. Background technique [0002] There are many blue reactive dyes on the market. KN-RSR Brilliant Blue is an anthraquinone reactive dye. It is widely used in the printing and dyeing industry for its bright shade, light fastness, and excellent weather (color) fastness. However, due to the characteristics of its own molecular structure, the molecules are easily associated, especially when the alkali is added to fix the color, the sulfate vinyl sulfone group is converted into a vinyl sulfone group, which is easier to be resolved by water, and it is easy to cause color spots on the fabric and reduce Improve the coloring rate, and produce more dyeing wastewater. [0003] With the rapid development of my country's economy, due to domestic energy shortages and serious environmental pollution...
