Reaktivna bojila su skupina bojila koja se najviše upotrebljavaju za bojadisanje celuloznih vlakana. Tijekom postupka bojadisanja ovim bojilima, hidroliza bojila može uzrokovati smanjenje učinkovitosti bojadisanja i otežano ispiranje bojila nakon bojadisanja. Uklanjanje hidroliziranog bojila s materijala postupkom ispiranja je vrlo važno kako bi se postigla dobra svojstva postojanosti obojenja. U ovom radu istraživana je primjena β-ciklodekstrina, nano-tvari sastavljene od 7 D-glukopiranozil jedinica povezanih alfa-(1,4) glikozidnim vezama, čime se pospješuje ispiranje hidroliziranog bojila nakon provedbe bojadisanja. Prema dobivenim rezultatima može se reći da je moguća primjena β-ciklodekstrina u ispiranju nakon bojadisanja reaktivnim bojilima za bojila koja s njima stvaraju (inclusion) komplekse.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 β-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 β-cyclodextrins is possible in washing treatments after reactive dyeing for dyes which form inclusion complex with it
