Résumé : |
In this paper, the solubilisation kinetics of three novel monoazo disperse dyes based on naphthalimdes incorporating a butyric acid group were investigated in different conditions using spectrophotometry. All dyes showed a reasonable level of solubilisation in alkaline media. Kinetic studies of the solubilisation reaction of the dyes in alkaline media showed that the rate of solubilisation of all dyes is a pseudo first-order reaction equation. The rate constants of the solubilisation reaction of the dyes in alkaline media indicated that dye 3, which is prepared by the diazotisation of 4-amino-n-butyric acid 1,8-naphthalimide and coupled with N,N-diethy-n-hydroxyethyllaniline, has the highest rate of reaction and dye 1, which is prepared by the diazotisation of 4-amino-n-butyric acid 1,8-naphthalimide and coupled with N,N-diethylaniline, has the lowest rate. The dyes were applied on polyester fabrics and their fastness properties were examined. The dyed fabrics showed a good to excellent degree of wash and rubbing fastnesses after replacing reduction clearing with alkali clearing. |
