Abstract
Multifunctional finishing of textiles enhances the value of products by adding desired biological and functional properties. The purpose of this study was to extract essential oil from lemongrass and apply the extracted oil to traditional cotton fabric as finishing. Lemongrass oleoresin was obtained by extracting fresh blades of lemongrass for 16 h using a Soxhlet extractor, employing n-hexane as solvent, by the AATCC Method 30-25. The pad-dry technique was applied to impart fragrance to cotton fabric by using a finishing formulation containing lemongrass oil and β-cyclodextrin-grafted chitosan. The ester bond formation between β-cyclodextrin-grafted chitosan and cellulose was confirmed by FTIR spectroscopy (FTIR). After finishing, the fragrance release rate was evaluated by UV-visible spectroscopy. The fragrance release rate of the finished fabric was found to be durable up to 18 washing cycles and the fabric presented excellent antibacterial property and antioxidant activity. Standard test methods were used to evaluate the physical properties of the treated fabric.
