Antibacterial Polyester Fiber

Polyester is a group of polymers that contain an ester functional group in their chain. Polyester fibers have high strength, low water absorption and minimal dehydration compared to other industrial fibers and are widely used in the clothing industry. Polymeric materials such as polyester can be easily contaminated by bacteria or fungi, which can lead to the transmission of serious diseases and infections. Prevention of surface contamination of these materials by germs can be achieved by the use of an active antibacterial agent such as nanoparticles within their structure. Nanoparticles interact with the outer membrane of the bacterium, causing structural changes inside the bacterium and eventually destroying it. Silver ions or zinc oxide are extremely deadly for a wide range of bacteria and are a common way to protect against bacteria. The use of nanoparticles in the yarn manufacturing process traps these nanoparticles in the body of the yarn and provides antibacterial properties with good shelf life. On the other hand, in order to reduce the odor of the body, microorganisms produced in sweat should be prevented. Silver has antibacterial properties and, due to its high permeability to silver nanoparticles, can kill microorganisms.
