Use weak acid brilliant red B should be dyed in the neutral dye bath, leveling agent should be added to improve its levelness. The color is more bright, is the main dye dyed pink. It is also used for color matching and color adjustment. It can also be used for the dyeing of silk and nylon, and the direct printing on wool and silk fabrics. It is used for hand printing on wool knitted products, and the effect is good. The wool/viscose blended fabric is dyed in the same bath with the direct sun-resistant dye, and the color is uniform.
used for dyeing silk, nylon and wool fabrics
production method with 5-chloro-2-phenoxyaniline and N-p-Toluenesulfonyl H acid as raw materials, the former is first diazotized and then coupled with the latter to obtain a product. After salting out, filtration, drying to obtain the finished product..
