Dark even powder. Soluble in water (purple) and soluble fiber element, slightly soluble in ethanol (red light blue), insoluble in other organic solvents. Meet strong sulfuric acid in deep dark, it will be diluted to appear blue; Nitric acid in a Purple dark reddish brown change after the orange. Its water solution meet strong hydrochloric acid is blue, in thick red orange brown in sodium hydroxide solution.

Appearance is dark blue uniform powder. Soluble in water (purple) and cellosolve, slightly soluble in ethanol (red light blue), insoluble in other organic solvents. Dark sulfuric acid in dark sulfuric acid, blue after dilution; In case of concentrated nitric acid, it is purple sauce color, and then turns orange. Its aqueous solution is blue in concentrated hydrochloric acid, and it is reddish orange brown in concentrated sodium hydroxide solution.

Acid Blue 92 Application:

Can dyeing wool, silk, viscose, leather, paper and soap.

Use condition:

1. It is used for dyeing and printing wool and silk, and can also be used for coloring leather, paper and soap.

2. Wool dyeing: In the weak acid bath, the pH value of the dyeing solution is adjusted to 4~6, and the leveling powder can be used as a retarding agent to improve the leveling property. The highest dyeing temperature is 85~95°C during the heating process. Dyeing with a concentrated acetic acid bath gives a deep red cyan color, which can be used for velvet, knitted fabrics and hats to dye cyan.

3. Silk dyeing: carried out in a weakly acidic bath with moderate leveling.

4. Blending of blended fabrics: When the wool is dyed in the same bath as the various fibers, the apparent color depth of the nylon is close to that of the wool, the silk is very shallow, and the cellulose fibers and the triacetate fibers are not stained.

Packing:

20 or 25kg/compound bag, carton box, iron drum, fiber durm for powder dye and 1000kg/tank for liquid dye
