red powder | [Uses]
ACID ORANGE 63 is suitable for dyeing wool, silk, nylon, and wool blends. It can also be used for direct printing on wool, silk, and nylon fabrics. It is generally used alone, but can also be used in combination with other dyes for dyeing coarse woolen fabrics and loose wool. It has good leveling properties, but a relatively low dye uptake. When used for dyeing wool with other fibers in the same bath, nylon achieves a color similar to wool, silk a lighter color, and acetate and cellulose fibers show slight staining. | [Preparation]
2-Amino-5-(4-aminophenyl)benzenesulfonic acid double nitriding, respectively with the 4-(3-Methyl-5-oxo-4,5-dihydropyrazol-1-yl)benzenesulfonic acid and phenol coupling, then use 4-Methylbenzene-1-sulfonyl chloride esterification of hydroxyl phenol. | [Properties and Applications]
orange. Orange powder, soluble in water. In the red for sulfuric acid, precipitation, diluted into old yellow, precipitation disappeared; In nitric acid to orange. The water solution is orange, join hydrochloric acid or sodium hydroxide colour and lustre is dark. Discharge performance is good. Copper ions and chromium in ion colour and lustre is no change, encounter iron ion turn dark colored. This product is mainly used for wool, silk, jin theory and its blended fabric dyeing and printing, the application of good performance
