Application of China Cationic black X-O Factory:
New cationic dyes
1) Migrating cationic dyes
The so-called migrating cationic dyes refer to a kind of dyes with simple structure, small molecular weight and molecular volume, and good diffusibility and leveling performance. At present, they have become a large category of cationic dyes;
2) Cationic dyes for modification:
In order to adapt to the dyeing of modified synthetic fibers, a batch of cationic dyes were screened and synthesized. The modified polyester fiber has the following structures: yellow is mainly conjugated methylchuan dyes; red is triazole or thiazole azo dyes and isolation azo dyes; blue is thiazole azo dyes and oxazine dyes.
3) Disperse cationic dyes
In order to adapt to the dyeing of modified synthetic fibers, a batch of cationic dyes were screened and synthesized.
4) Reactive cationic dyes:
Reactive cationic dyes are a new type of cationic dyes. The introduction of reactive groups into conjugated or isolated dyes gives them special properties, especially in blended fibers, which can not only keep bright color, but also dye many kinds of fibers.
