Prepara tion of β-Cyclodextrin/Latex Dispersion for Coating of Cellulose Fabric
In recent years there has been an increasing demand for the application of natural products to address problems in the environment. The use of products derived from renewable resources can provide a sustainable strategy to replace totally or partially synthetic products. Cymbopogon, commonly known as lemongrass, is a tropical grass cultivated mostly for its essential oil, which has demonstrated several bioactivities, including antibacterial and antifungal properties. In the present work the formation of inclusion complex between β-cyclodextrin (β-CD) and lemongrass essential oil (LGEO) as well as its fixation onto cotton fabric were investigated. Inclusion complex was prepared through solution method followed by freeze-drying. The starting materials and inclusion complex were characterized by FTIR, TG/DTG and SEM. The cotton fabric incorporated with inclusion complex was investigated by FTIR and XRD. The results suggested the success of complexation in the molar ratio of 0.015:0.018 mol/L (LGEO: β-CD) and the viability of fixing the inclusion complex leading to a potential functional textile.
