Kationisk rød XGRL
Kationisk rød XGRL is a kind of cationic dye. The cation of the dye can be combined with the acid group of the third monomer in the fabric to dye the fiber. It is a special dye for acrylic fiber dyeing; a cationic dye produced by Milestone Industrial Co. ltd. It has the advantages of high strength, bright color and good light fastness, etc., and has been widely used and praised by customers;

Influencing factors of Cationic RødXGRL staining
1. The effect of Kationisk rød XGRL dyeing has a great affinity for acrylic fiber. It is easy to produce uneven dyeing due to fast absorption and slow diffusion during dyeing. Once uneven dyeing occurs, it is difficult to correct it by extending the dyeing time. Therefore, the type of acrylic fiber has a great influence on the dyeing rate;
2. The influence of temperature on the dyeing of Kationisk rød XGRL: Temperature is an important factor to control level dyeing. When acrylic fibers are dyed with cationic dyes, they are rarely dyed below 75°C. When the dyeing temperature reaches the glass transition temperature of the fiber (75-85°C), the dye uptake rate increases rapidly. Therefore, when the dyeing temperature reaches the glass transition temperature of the fiber, the temperature should be raised slowly, generally 1°C every 2 to 4 minutes. It can also be kept at 85～90℃for dyeing for a period of time, and then continue to heat up to boiling.
