Disperse Blue 183 Usage And Synthesis

Preparation

2-Cyano-4-nitro-6-bromoaniline diazo, and N-(3-(diethylamino)phenyl)propionamide?coupling.

Properties and Applications

blue. Blue-black powder. Soluble in acetone, DMF. Used for polyester and their blended fabric dyeing, lifting force high, suitable for dyeing very deep colour and lustre, high temperature and high pressure method is suitable for the dye shallow, color, levelness and poor coverage. With the melt method dye, lifting force is high, used for polyester/cotton blended, can direct dyes and a bath dyeing of step. Suitable for polyester fiber dyeing and superfine of printing. In addition to the three vinegar fiber, is not suitable for dyeing other fiber, dye three vinegar fiber, dyeing rate is not high. Can be used for direct printing polyester fabric, light color can make discharge printing.
