The cationization of cotton fibers is emerging
as an effective tool for solving the environmental problems
associated with the dyeing of cotton fabrics with
anionic dyes. In this study, the dyeing performance of cationizing
agents (Rucomor Bur, Kemifix REA, Optifix F,
and Optifix RSL) were examined, and we found that this
method had better results compared with normal or existing
methods of reactive dyeing. The dye-bath exhaustion
and fixation were determined by the help of an ultraviolet–
visible absorbance spectrophotometer on the basis of
the maximum absorbance wavelength. Better fixation values
were found with the cationizing process than with
salty dyeing. The washing and rubbing fastness results
were as the same as those of traditional dyeing
