    The efficiency of ?-cyclodextrin in the post-dyeing removal of hydrolyzed reactive dyes
    (2013) Kumbasar, P.A.; Atav, Rıza; Özkaya, K.; Yurdakul, Abbas
    Reactive dyes are the most commonly used dye class in cellulosic fibers dyeing. But during dyeing with these dyes, the hydrolyzation of dye may decrease dyeing efficiency and may cause the washing treatments after dyeing to be much harder. It is very important to remove hydrolyzed reactive dye from the textile material by washing treatments to obtain the desired fastness properties. In this research, usage possibilities of ?-cyclodextrins, that are nano-substances structurally consist of 7 D-glucopyranosyl units connected by alpha-(1, 4) glycosidic linkages, to enhance hydrolyzed reactive dye in washing treatments after reactive dyeing were investigated. According to the experimental results, it can be said that usage of ?-cyclodextrins is possible in washing treatments after reactive dyeing for dyes which form inclusion complex with it.
