        Reuse of Effluent Water Obtained in Ultrafiltration of Reactive Dyes

        Smaro Lykidou,Evangelos Karanikas,Chrysa Anagnostopoulou,Nikolaos Nikolaidis,Eforia Tsatsaroni 한국섬유공학회 2019 Fibers and polymers Vol.20 No.6

        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.

        Study on the Dyeing Properties of a Novel Reactive Dye with One Vinylsulfone Reactive Group, on Cotton Substrates, Before and After Its Ultrafiltration Treatment

        Smaro Lykidou,Eleftheria Gitsouli,Vasileios Daniilidis,Evangelia Vouvoudi,Nikolaos F. Nikolaidis 한국섬유공학회 2023 Fibers and polymers Vol.24 No.11

        Reactive dyes are widely used in the textile industry due to their versatility of shades, high wash fastness properties, and the ease of application. Dyeing properties such as exhaustion, substantivity, fixation, time to half dyeing, migration index and effect of metal salts were studied for a novel reactive dye (named RRNa) synthesized with one vinylsulfone as reactive group. The aim of this study is to figure out the influence of the ultrafiltration process this dye went through on its aforementioned properties. It was found that the ultrafiltrated reactive dye shows higher exhaustion, substantivity, dye uptake than the original dye, which is attributed to the purification performed by the ultrafiltration process. The migration index is slightly lower for the ultrafiltrated dye which indicates that its mobility is lower, due to the possible formation of more covalent bonds between the dye and the substrate. The effect of metals (Fe, Co, Cu) was also studied and the color strength of the dyeings in the presence of sulfate salts was compared with the control sample. It was found that Co2+ and Cu2+ have a detrimental effect on the shade obtained, whereas Fe3+ reduces color strength to a lower extent.
