2.5.3. Dye temperature
Dyeing was performed at six different temperatures, namely, 75,80, 85, 90, 95 and 100 C. Sodium chloride (5 g/L) was used as an accelerant and the process was maintained at the specified temperature for 50 min. No adjustment of pH was made. The dye concentration and liquor ratio were kept constant as those obtained from the previous experiment.
