The effects of two-step fixation of steaming and baking on the dischargeability of cotton fabrics dyed with C.I. Reactive Black 5(Bl-5) were investigated when the concentrations of and benzaldehyde sodium bisulfite(BASB) were increased over 120/kg. Remarkably increased dischargeability resulted from baking for 3 min or more at 160t after steaming for 8 min or more at , but 120g/kg or more amounts of and BASB(50%) had little influence on dischargeability. Therefore the discharge mechanism can be suggested that covalent bonds between cellulose and Bl-5 undergo attack by hydroxide ion formed by the reaction of and water in steaming at first and then, through transition states they are cleavaged in baking at 160t to yield hydrolyzed Bl-S and compounds of BASB and Bl-5 isolated from fiber, which are undyeable and removed by washing. The effect of urea, one of the hydrotrope agents, on discharge printing was also studied. The result which dischargeability was greatly improved by increasing the steaming time from 8 min to 15 min at or by increasing the amount of urea obviously shows that water in steaming and urea in print paste play an important role in discharge printing. And as an increase of the baking time from 5 min to 7 min at makes it possible to improve dischargeability, it is once more confirmed that high temperature of about 160t is exactly required to discharge the dyed Bl-5. The colored discharge printing demands a more amount of urea because urea contributes to the putting color fixation as well as the discharge reaction. |
