H Type Dyes (Monochloro Triazine Based)

This type of reactive dyes has low reactivity and substantivity. As they have low reactivity, these dyes require more severe conditions for fixation of cellulosic materials. To make these dyes readily soluble, pour water of 80-85oC on powder and stir it well. When compared with cold brand dyes, the ‘H’ brand ones require high thermo fixation temperature and long steaming time for the purpose of its optimum fixation.
