The Influence of Pretreatment and Various Cross-Linking Agents on Binding of β- Cyclodextrin and Cotton

β-Cyclodextrin (β-CD) is a cyclic glucose polymer that can include other molecules within a structural cavity to form a microcapsule with many products based on organic and inorganic compounds. The purpose of this research was to establish an optimal method of bonding β- cyclodextrin onto cotton, using citric (CA) and maleic acid (MA) as non-aggressive cross- linking agents. The grafted amount was determined by gravimetric method and the treated fabrics were analyzed by Fourier transform infrared spectroscopy (FTIR). Scanning electron microscopy (SEM) was employed to study the morphology and structure of cellulose materials treated with β- cyclodextrin. The results indicated that probably a more stable bonding between cellulose and β-cyclodextrine was achieved in the sample, which was pre-treated in alkaline bath and treated with β-CD and MA as cross- linking agents.
