The Reactive Black 5 and Reactive Red dyestuffs have been synthesized in the laboratory. The synthesis wasobtained by diazotization of 1-amino-phenyl-4-beta hydroxyethyl sulfone sulfate ester and coupling with 1-amino-8-hydroxynaphthalene-3,6-disulfonic acid (H-acid) (mole ratio 2:1) (Reactive Black 5Na) and (mole ratio 1:1) (Reactive RedNa). The dye was purified-concentrated by ultrafiltration technology and the permeate (waste) was used as dye bath in theexhaustion of cotton and polyamide with the sodium salt of Reactive Black 5 (RB5Na) and the sodium salt of Reactive Red(RRNa). The same dyeing was also made with fresh water as dye bath. Fastness properties were also measured in both casesand the results were compared. Color measurement results of the dyeings were almost the same when the waste as dye bathwas used.
