Direct Yellow 86 Application:

Most suitable for dyeing of viscose like cotton, flax, viscose rayon, acetate and jute, also for Ink, Leather and Paper coloration.

Use condition:

Direct Yellow 86 For the dyeing of cotton and viscose fibers in a one-bath one-step dyeing process for polyester-cotton, polyester-bonded or cotton-nitrile blended fabrics, it can be dyed in the same bath as the disperse dyes, or as a direct dye.

It can be used as a substitute dye for CIDirectYellow24 and CIDirectYellow48.

It has high directness to cellulose fiber and high dyeing rate, that is, it uses a small amount of inorganic salt and has a high dye uptake rate.

There is no aggregation in the dye bath at 130 ° C. The pH value of the dye bath is wide, and the cellulose dye has a good dye uptake rate under acidic conditions.


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