Multifunctional Linen Fabric Obtained through Finishing with Chitosan-gelatin Microcapsules Loaded with Cinnamon Oil

Abstract

ABSTRACT In the 21st century, the occurrences of deadly viruses, mosquito-borne and pathogenic diseases have increased significantly. To avoid the spread of these diseases, one of the best strategies is to use protective textile products such as functional (antibacterial, antioxidant, antiviral, mosquito repellent) mask, scarf, gowns, curtains, bedsheets, etc. The present work deals with the preparation of chitosan-gelatin microcapsules loaded with cinnamon bark oil and the application of prepared microcapsules to the linen to develop multifunctional protective linen fabric. The scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) and Fourier transform infrared (ATR-FTIR) spectroscopy were utilized to characterize the prepared microcapsules and the finished fabric. The encapsulation efficiency of microcapsules was also calculated to optimize the concentration of polymers and oil. The chitosan-gelatin shell on cinnamon bark oil core provided a controlled-release system, which delivers excellent washing durability to the functionalities of the finished linen. The finished linen with an excellent antibacterial property against E. coli and S. aureus bacteria and outstanding mosquito repellency (up to 100%) durable up to 20 washes was obtained. The finished fabric also showed durable and efficient antioxidant property and a fragrance. The use of bio-materials for the functional finishing of linen was reported.
