Appearance is green powder. Soluble in water, the solution has no tendency to aggregate at room temperature, soluble in o-chlorophenol, slightly soluble in acetone, ethanol, pyridine, insoluble in chloroform, toluene. The dye is dark green in concentrated sulfuric acid, diluted It turns into emerald blue; it is brown in concentrated nitric acid. The aqueous solution is blue, hydrochloric acid is blue, and sodium hydroxide is blue-green.

Green powder. Soluble in water, no solution at room temperature gather the tendency. Soluble in o-chlorophenol, slightly soluble in acetone, ethanol, Pyridine, insoluble in chloroform, toluene. The strong sulfuric acid dyes shows blackish green color, diluted Tracy turn blue; In nitric acid are brown.

Acid Green 25 Application:

Used for wool, polyamide, silk and their blended fabric dyeing and printing. Can also be used in leather, paper, cosmetics, soap, wood, electrical-controlled aluminum and biological color.

Use condition:

1. It is used for dyeing and printing wool, silk, nylon and its blended fabrics. It can be used as the main dye for medium and dark dyeing. It can also be used for coloring leather, paper, cosmetics, soap, wood and anodized aluminum.

2. Wool dyeing is carried out in a weakly acidic bath. The pH of the dyeing bath is adjusted to 4-6. The dye is not resistant to high temperature cooking; silk and nylon dyeing should be carried out in an acetic acid bath.

3. When dyeing wool with various fibers in the same bath, nylon is colored, the apparent color depth of silk is lighter than wool, polyester stain, cellulose fiber and triacetate fiber are not stained. Dyeing wool or silk with cotton or sticky The rubber blended interwoven fabric can be dyed in the neutral bath with the direct dye in the same bath; the silk and cellulose fiber blended interwoven fabric is dyed with a neutral bath, and the wet treatment fastness is worse than the wool dyeing.

4. When dyeing, the copper ion color is basically unchanged, and the iron ion color is slightly dark.

5. It is suitable for direct printing of wool, silk and nylon fabrics, and can be used as flower dyes for stannous chloride discharge printing.

Packing:

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