EMF series reactive dyes are major research and development achievements in the development of dyes, to achieve the birth of reactive dyes alkali free dyeing. It has high dyeing rate under neutral dyeing conditions, reducing the hydrolysis rate of dyes, good synchronization and compatibility of dyes, convenient and fast operation in dyeing and adding color, good dyeing ability is not easy to produce color flowers, shorten the dyeing process time, improve production efficiency and reduce the overall cost of dyeing. It is suitable for light medium color series dyeing of cellulose fibers such as cotton and hemp, and for light color series dyeing of blended fabrics such as disperse/active one bath method.
