Reactive dye for turquoise blue printing based on copper phthalocyanine color body and preparation method and application thereof

Abstract

The present invention relates to a reactive dye for a turquoise blue printing based on a copper phthalocyanine color body and a preparation method and an application thereof. The kind of the turquoiseblue reactive dye is obtained by chlorosulfonation of copper phthalocyanine, preparation of phthalocyanine turquoise blue base, primary condensation and secondary condensation. The obtained turquoiseblue reactive dye is suitable for printing on cotton, linen and other textiles, has an excellent easy water washing ability, good leveling property and excellent lifting power and dyeing depth, and has a higher fixation rate than that of commercial dyes, and printing textiles show relatively excellent color fastness to light and rubbing color fastness, and have a very good application prospect.

Description

technical field [0001] The invention belongs to the field of reactive dyes, in particular to a class of reactive dyes for emerald blue printing based on copper phthalocyanine chromophores and a preparation method and application thereof. Background technique [0002] Reactive dyes have developed rapidly because they can be combined with fibers by covalent bonds, have excellent wet fastness and level dyeing performance, bright colors, complete chromatograms, and low cost. Most of the light-colored varieties of reactive dyes such as yellow, orange, and red have an azo structure, and the purple, brown, and black varieties often use metal-complexed azo structures. Most of the bright blue colors are anthraquinone derivatives. The reactive turquoise blue dye whose parent is copper phthalocyanine has always occupied a very important position because of its unique turquoise blue color. At present, reactive turquoise blue dye is often used to mix bright green with reactive bright ye...

AI Technical Summary

Problems solved by technology

At present, reactive turquoise blue dye is often used to mix bright green with reactive bright yellow dye. However, due to the different structure of the dyes in the process of blending green, the dyeing rate, lifting power, and color fixation rate of each dye are different, and printing and dyeing fabrics will appear The color reproducibility is poor, the vat difference is large, and the color fastness is affected. Therefore, it is very important to develop a single-structure light green reactive dye to improve the color reproducibility.
