Soluble in water solution for big red, slightly soluble in ethanol and soluble fiber element, insoluble in other organic solvents. Meet strong sulfuric acid is blue light red, it will be diluted in a yellow after red; Meet nitric acid solution is orange turn orange; Meet strong hydrochloric acid generation red precipitation, dilute it dissolve. The aqueous solution of dyes and strong hydrochloric acid is product red; Add sodium hydroxide is orange brown. Copper ions in dyeing and dark blue colour and lustre to take; Iron ion in color with blue and light. Good levelness. 

Appearance is red powder. Soluble in water, large red in aqueous solution. Slightly soluble in ethanol and cellosolve, insoluble in other organic solvents. When concentrated sulfuric acid is blue-red, it will be diluted to a yellowish red color; Concentrated nitric acid turns orange when it is orange-red solution; it forms a red precipitate when concentrated hydrochloric acid, and dissolves after dilution. In its aqueous solution, concentrated hydrochloric acid is magenta, and sodium hydroxide is orange-brown.

Acid Red 1 Application:

Mainly used in strong acid medium in the wool dyeing and the piece dyed wool. Can be directly in the wool fabrics, polyamide fiber and fabric silk printing. Also can be used for leather dyeing, also can be used in the manufacture of color amylum, cosmetics, paper, soap and timber colorants, is used to make the ink. The Barium salt can be used in organic pigments.

Acid Red 1 Use condition:

1. It is used for dyeing and printing wool, silk and nylon. It can also be used for leather dyeing. It can also be used to make coloration of lake, cosmetics, paper, soap and wood. It is used in the manufacture of ink. It is rarely used in silk printing. Mainly used for wool dyeing and wool dyeing in strong acid media.

2. Wool dyeing: It is carried out in a strong acid bath. The pH value of the dyeing solution is adjusted to 2~4, which is suitable for boiling dyeing. The Jiayuanming powder can promote retarding dyeing. When dyeing wool, the leveling effect is good, the color is bright, suitable for dyeing light. color.

3. 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 similar to that of the wool, the silk color is light, and the cellulose fibers are not stained.

4. When dyeing, the copper ion color is blue and dark, and the iron ion color is blue and light.

Packing:

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