HE Dyes are Reactive Dyes for cellulosic material and are designed to give high fixation by exhaust dyeing methods when applied at the temperature 75" 90º C. HE dyes are suitable for dying cotton and other cellulosic materials. These dyes process significantly higher exhausation and Fixation efficiency which result in appreciable cost reduction, in compariso to Conventional reactive dyes. Some advantages of HE Dyes have:-
(i) Excellent compatibility
(ii) Good built up.
(iii) Excellent Reproducibility
(iv) Wide Applicability
(v) Outstading built up and consistency.

Method Of Dyeing

Set the dye bath at 50 and add dyestuff. Run for 15 Minutes. Add half of the glauber salt and continue Dyeing Raise the temperature to 80º-85º c and run for 15 minutes. Add soda Ash solution and run 30-60 minutes. Wash properly the material.
