What are the characteristics of reactive dyes?

Solubility: Good-quality reactive dyes have good water solubility for commercial applications. Diffusion: refers to the ability of the dye to move into the fiber, and the diffusion of dye molecules under temperature. Reactivity: refers to the ability of the dye to react with the cellulose hydroxyl group. The dye with strong reactivity can be fixed under the condition of room temperature and weak alkali.
