Classification Of Reactive Dyeing
Classification Of Reactive Dyeing According to different reactive groups, reactive dyes can be divided into two types: symmetrical triazene type and vinylsulfone type. Symmetric triazene type: In this type of reactive dyes, the chemical properties of active chlorine atoms are more active. During ...Read more -
History Of Reactive Dyes
History Of Reactive Dyes Ciba began to study melamine dyes in the 1920s. The performance of melamine dyes is better than all direct dyes, especially Chloramine Fast Blue 8G. It is a blue dye composed of intrinsic binding molecules containing an amine group and a yellow dye with a cyanuryl ring to...Read more -

Why Is The Dispersion Fastness Poor?
Why Is The Dispersion Fastness Poor? Disperse dyeing mainly uses high temperature and high pressure when dyeing polyester fibers. Although the disperse dye molecules are small, it cannot guarantee that all the dye molecules enter the fiber during dyeing. Some disperse dyes will adhere to the fibe...Read more -
Disperse Dyeing Process
When dyeing at high temperature and high pressure. Disperse dyeing process of polyester fiber. Divided into four stages 1. Disperse dyes migrate from the dye solution to the fiber surface due to the difference in concentration: 2. Disperse dyes are adsorbed to the fiber surface: 3. Disperse dye p...Read more -

Unlike some direct dyes, the dyes are not toxic or carcinogenic. These direct dyes have not been widely used in general-...Read more -
Analysis of Causes of Aggregation of Reactive Dyes
Reactive Dyeing has a very good dissolution state in water. Reactive dyes mainly rely on the sulfonic acid group on the dye molecule to dissolve in water. For meso-temperature reactive dyes containing vinylsulfone groups, except for sulfonic acid groups In addition, its β-ethylsulfone sulfate is ...Read more -
