Abstract

The invention provides turquoise blue reactive dye as well as a preparation method and application thereof. The dye has the following structure shown in the specification, wherein in the formula, x+y =3.5. The dye has small average particle diameter and low saltness; when in dyeing, the dye has gorgeous color, high coloring rate and good stability and repeatability; and the turquoise blue reactive dye is particularly suitable for inkjet printing, has excellent application performance and is convenient for use. Simultaneously, environment pollution can be reduced by the preparation and application of the dye, and the cost of the required raw material is low.

Description

technical field [0001] The invention relates to a reactive dye and its preparation method and application, in particular to a turquoise blue reactive dye, its preparation method and its application in ink-jet printing. Background technique [0002] Inkjet printing technology is one of the main areas. There are two main types of this technology: continuous inkjet and drop-on-demand. These two printing technologies have special requirements for the dyes or organic pigments in the ink, such as the chemical structure of the dye, the average particle size, the conductivity of the aqueous solution, the pH value of the dye, the purity of the dye, especially the content of inorganic salts, etc. With the development of digital technology, using computers to precisely control the dyeing process can improve production efficiency and yield, reduce production costs, and minimize the pollution of wastewater. However, the current inkjet dyes have a large average particle size and a high sa...
