Abstract

The invention discloses blue wool reactive dye and a preparation method thereof. The general formula of the dye is as shown (on the lower right). The preparation method for the blue reactive dye comprises the following steps: copper phthalocyanine, a chlorosulfonic acid, thionyl chloride, ethanolamine and oleum are taken as main raw materials, and the blue wool reactive dye is prepared by chlorosulfonation, condensation, esterification, improvement of the concentration of the dye, adjustment of the chromatic light, adjustment of the strength, drying and packaging. The blue wool reactive dye obtained has higher reactivity, superior solubility, colorful chromatic light, good lightfastness performance and high exhaustion rate and fixation rate, and does not contain free metal ions and chemical raw materials which are strictly prohibited to be used. By adoption of the pre-mixing technology after film treatment, waste water and waste residue can be prevented from being generated, so that the blue wool reactive dye greatly promotes environmental protection.

Description

technical field

[0001] The invention relates to a reactive dye for wool and a preparation method thereof, in particular to a blue reactive dye for wool and a preparation method thereof. Background technique

[0002] Now generally dyeing wool and cashmere, the dyes used are acid dyes, acid mordant dyes and metal complex dyes. Because the materials dyed with these types of dyes have poor fastness, the shade is not very bright, and it will cause troubles to the environment. In the 21st century, due to environmental and ecological constraints, the requirements for color uptake rate, color fixation rate and dyeing wastewater are getting higher and higher. Acid dyes can no longer meet the development of the times. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a blue reactive dye for wool that can reduce environmental pollution, has low raw material cost, high product solubility, bright color, excellent application ...
