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

ABSTRACT

In the 21^st 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.

摘要

进入21世纪，致命病毒、蚊媒传染病和致病性疾病的发生显著增加. 为了避免这些疾病的传播，最好的策略之一就是使用防护性纺织品，如功能性（抗菌、抗氧化、抗病毒、驱蚊）面膜、围巾、长袍、窗帘、床单等. 研究了以肉桂油为载体的壳聚糖-明胶微胶囊的制备及其在亚麻织物中的应用，以开发多功能亚麻防护织物. 利用扫描电子显微镜（SEM）、能量色散X射线（EDX）和傅立叶变换红外光谱（ATR-FTIR）对制备的微胶囊和织物进行了表征. 计算了微胶囊的包封率，优化了聚合物和油的浓度. 壳聚糖-明胶壳在肉桂皮油芯上提供了一种控释系统，该系统对成品亚麻的功能提供了极好的耐洗性. 整理后的亚麻具有优良的抗菌性能，对大肠杆菌和金黄色葡萄球菌的细菌和出色的驱蚊（高达100%）持久长达20洗. 整理后的织物还显示出持久有效的抗氧化性能和香味. 介绍了生物材料在亚麻功能整理中的应用.
