Direct Red 227 For the one-bath one-step dyeing process of polyester-cotton, polyester-bonded or cotton-nitrile blended fabrics, the dyeing of cotton and viscose fibers can be dyed in the same bath as the disperse dyes or as a direct dye.

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

The dye solution has good stability and does not agglomerate in the dye bath at 130 ° C. The pH value of the dye bath Wide adaptability, good dyeing rate for cellulose fibers under acidic conditions.


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