Abstract:

The aim of this study is to study the effects of different sterilization methods on electro-powered polyester fiber. PET fibers are produced by electroactivation method from solutions containing 10.15 and 20 percent weight polyethylene thermostat (PET) and sterilized by ethylene oxide (EO), otoclav (AU) and ultraviolet (UV). The surface characterization of the produced surfaces is carried out with scanned electron microscope (SEM), atomic power microscope (AFM), surface porosity size analysis and contact angle measurements. Thermal characteristics of surfaces Differential Scanning Calorometer (DSC) tests; micro-structure characteristics have been studied with Fourier Transform Infrared Spectroscopy (FTIR). SEM studies have shown that different sterilization methods cause major changes depending on polymer concentration. Although the effects of the methods are reduced with increased polymer concentration, the fiber structure – especially in EO sterilization – has been significantly damaged. A significant decline in contact values has been seen after UV sterilization.
