Sažetak
The surface of polyester fabric made of poly(ethylene-terephthalate) (PET) needs to be modified for better comfort and other properties. The conventional modifications as e.g. aminolysis with EDA and hydrolysis with NaOH, are not environmentally friendly. Therefore, the alternative methods of PET hydrolysis are researched to reduce water consumption, increase energy-efficiency and cut emissions of hazardous chemicals. One of alternative is enzymatic surface modification. The present paper deals with the cutinase modification of polyester fabric surface for achieving better hydrophilicity, and potential silk-like fabric. Cutinases were applied in two concentrations for 80, 100 and 120°C. The characterization of surface and chemical composition of such treated polyester fabrics is performed by scanning electron microscopy (SEM) on FEI Quanta 200 Scanning Electron Microscope with magnification 2500x ; and Fourier Transform Infrared - Attenuated Total Reflectance (FTIR- ATR) spectroscopy on Perkin-Elmer Spectrum 100 FT-IR.
