Abstract
The purpose of this work was to prepare chitosan–essential oil microcapsules using the simple coacervation method and to graft them onto cellulosic fibers to obtain bio functional textile. The microcapsules morphology was characterized by optical microscopy. The 2D dimethyloldihydroxyethylene urea resin (DMDHEU) was used as a binding agent to graft microcapsules on the surface of cellulosic fibers. Scanning Electron Microscopy (SEM) photographs and Attenuated Total Reflectance-Fourier Transformed Infrared (ATR-FTIR) analyses were performed to prove the interaction between cellulosic fibers and microcapsules. Furthermore, the properties of the different fabrics such as mechanical strength and air permeability were investigated. Furthermore, washing durability was evaluated. Finally, the antibacterial activity of the finished fibers against the strains Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) was evaluated. The results evidence the ability of treated fabrics to induce bacteria growth inhibition. The coacervation method is a simple process to incorporate cinnamon essential oil on the cellulosic fiber’s surface. The use of essential oils as active agents seems to be a promising tool for many protective textile substrates such as antimicrobial masks, bacteriostatic fabrics and healthcare textiles.

In recent years, the incidence of viruses, bacteria, parasites and fungi has risen considerably, especially among immune-compromised patients, geriatric and pediatric [1].The uncontrolled growth of infectious diseases, which are becoming harder to treat, is a silent threat with long-term consequences for global public health and economy [2]

Summary
The incidence of viruses, bacteria, parasites and fungi has risen considerably, especially among immune-compromised patients, geriatric and pediatric [1]. The uncontrolled growth of infectious diseases, which are becoming harder to treat, is a silent threat with long-term consequences for global public health and economy [2]. The. COVID-19 crisis has brought into sharp focus the impact of infectious diseases. There are vital lessons to learn from this pandemic. We need to make robust and comprehensive investments into the way we prepare and respond to health emergencies. This has the potential to avoid into long-term, global health threats and economic crises. A major challenge facing textile industries is to enhance the production of protective textiles
