In order to study the dyeability of reactive dyes fixable at neutral pH, three reactive dyes(DYE-NC, DYE-PC, and DYE-LC) were prepared by the reaction of Cibacron Brilliant Red 3B-A with nicotinic acid, pyridine, and lutidine, respectively. FT-IR and UV/Vis spectrophometry were used to identify the dyes prepared. While the maximum absorption wavelength () of Cibacron Brilliant Red 3B-A was 515nm, the of DYE-NC, DYE-PC, and DYE-LC were 522nm, 525nm, and 536nm, respectively. The was shifted to the longer wavelength by introducing the electron donating groups to the pyridine ring of Cibacron Brilliant Red 3B-A. All of the reactive dyes synthesized showed good exhaustion and fixation property to cotton fabric at higher temperature and neutral pH condition. It was regarded that the quaternary pyridinium ion functionated as the leaving group instead of the chloride ion. Among them, DYE-NC showed the best dyeability at the above condition. It was considered that the electron withdrawing carboxylic acid group in nicotinic acid enhanced the cationic property of nitrogn in pyridine ring, resulting the good reactivity with OH group in cellulose. |
