Direct Blue 106 Chemical Properties, Uses, Production

Chemical Properties

Gray-black powder. Soluble in water, solubility in water (80-85℃) is 20g/L. The aqueous solution is blue. When stained with copper, iron ions, the color light becomes green and dark.

Uses

Direct Blue 106 is mainly used for dyeing and printing on cotton, viscose, nylon, silk, and wool, producing a bright blue color with excellent fastness and vibrancy. However, it is not suitable for discharge dyeing, as its migration and dyeing rates are relatively poor. It can also be used for dyeing blended fabrics such as polyester/cotton, polyester/viscose, and wool/viscose. It can be used in the same high-temperature bath as disperse dyes to dye polyester/viscose fabrics without significantly altering the color. When cotton, viscose, silk, and wool are dyed in the same bath, the resulting colors are similar. It can also be used for direct printing on cotton and viscose fabrics, as well as for dyeing leather.

Preparation

5-Amino-2-(phenylamino)benzenesulfonic acid and the 2,3,5,6-Tetrachlorocyclohexa-2,5 -diene-1,4-dione in the water to magnesium oxide bound for acid agents for condensation, its product to hair smoke closed-loop have to dioxazine sulfuric acid, and then as two sodium salting out.

brand name

Solophenyl Brilliant Blue BL, Chlorantin Fast Brilliant Blue 2 GL (Ciba-Geigy), Tertro Direct Light Blue 2GLN (Crompton & Knowles).

Properties and Applications

bright blue. Mainly used for cotton, viscose, silk, polyamide fiber fabric dyeing and printing, also can be used for leather dyeing.
