SURFACE MODIFICATION OF LOW TEMPERATURE PLASMA TREATED POLYESTER AND RAYON FABRICS

Abstract :

 In this study polyester and rayon faics were treated with plasma application. Polyester faics after initiated by plasma were grafted with maleic acid in order to enhance wettability. Structural and surface changes were analyzed using XRD, FTIR and SEM. Wettability and dye absorption were also investigated. The percentage of crystallinity was decreased on the surface of plasma treated polyester faic. No significant change was observed in case of rayon faics. From FTIR studies, it was found that (–OH) group was induced in case of grafted polyester faic. Deposition of a thick film on the surface of polyester fiber and hence a change in morphology of the faic surface was confirmed by scanning electron microscope. The wetability of polyester and rayon faics was improved by plasma treatment.
