PET (Poly ethylene terephthalate) fabric was treated using dielectric
barrier discharge (DBD) as a type of low temperature plasma under
atmospheric pressure for 1 to 15 min and different powers ranging between
0.3 to 5 W. Effects of DBD treatment on the surface of a test PET fabric
are examined, reported and discussed. The surface analysis and
characterization were performed using X-ray diffraction (XRD), Fourier
transition infrared spectroscopy (FTIR) and scanning electron microscopy
(SEM) before and following the DBD processing. SEM analysis shows significant surface morphology changes in plasma treated polyester fabric surface, while FTIR analysis indicates that the reactivity of the surface was increased. The discharge parameters used are correlated
with the changes in the surface characteristics found after DBD processing
of various durations, in atmospheric air environment.
