Polyester is a group of polymers that contains one ester functional group in their chain. Polyester fibers have high strength, low water absorption, and least sagging compared to other industrial fibers, and are widely used in the garment industry. These substances can be easily contaminated by bacteria or fungi, which can lead to the transmission of severe diseases and infections. Preventing contamination of the surface of these materials by microbes can be performed by using an active antibacterial agent such as nanoparticles within their structure or applying antibacterial coatings. Nanoparticles react with the outer membrane of the bacterium to cause structural changes inside the bacterium and eventually destroy it.
