Cationic Yellow X-GRL Application

Cationic Yellow X-GRL is mainly used for dyeing and printing acrylic fibers and their textiles.

Cationic Yellow X-GRL dyeing method and mechanism

Cationic Yellow X-GRL is a special dye for acrylonitrile fiber. The dyeing method is to use acetic acid and sodium acetate as buffers in a weakly acidic (pH value of about 4.5) bathtub. In the presence of a dielectric and appropriate additives, it is close to boiling. dyeing.

The dyeing mechanism of Cationic Yellow X-GRL can be divided into three steps:

(1) The dye cations in the dye bath are adsorbed on the fiber surface.

(2) Dye cations diffuse from the surface of the fiber to the inside.

(3) The dye cation and the anionic group contained in the fiber form a salt bond.
