HPLC Analysis of Monofluoro-S-Triazine Dye during the Dyeing Process
Abstract: In the research, the HPLC technique was applied in order to monitor the hydrolysis and dye-fibre bond-forming during the dyeing process. The results show that using a proper execution of calibration curves of the active and hydrolyzed form of the dye and defined equations, HPLC technique enable determining the exact amount of both dye forms anytime during dyeing. Dyeing process was performed in dyeing machine with use of combination of both alkalis—Na2CO3 and NaOH—and with use of one alkali—Na2CO3. It was established that NaOH causes additional hydrolysis of the dye and that the use of Na2CO3 is more appropriate for Novacron Scarlet F-3G dye. The temperature of adsorption has no influence on dye fixation; an amount of fixed dye on fibre is up to 83.0%.
