**4. Conclusions**

Essential oils are a family of natural compounds that are well known for their biological activities. They are applied to many treatments. The goal of this work was to apply a mixture of essential oils (cinnamon oil and clove oil) for the functionalization of cellulosic fibers. Essential oils were extracted by hydro-distillation. The extracted oils were characterized by GC/MS. This technique revealed the chemical composition of each oil. Chitosan was used to produce essential oil microcapsules, which were then grafted on the cotton fabric surface via citric acid. Some textile properties were evaluated, such as wettability and mechanical properties

Finally, antibacterial activity of different samples was assessed. It was concluded that essential oil combination is a promising tool to provide antimicrobial agents with a broad spectrum of activity. Moreover, the encapsulation avoids the rapid evaporation and degradation of their active components. The application of encapsulated oil mixture enhances the efficacy against multi-resistant pathogens.
