Influence of Atmospheric Pressure Plasma Pre-Treatment on Sodium Bicarbonate Desizing of Polyacrylate on PET Fabrics
The influence of He/O2 atmospheric pressure plasma jet (APPJ) treatment on subsequent wet desizing of polyarylate from PET fabrics was studied in present paper. Scanning electron microscopy (SEM) analysis showed an increased surface roughness after the plasma treatment. And SEM results also showed that the fiber surfaces were as clean as unsized fibers surfaces after 35s treatment followed by NaHCO3 desizing. X-ray photoelectron spectroscopy (XPS) analysis indicated that oxygen-based functional groups increased for the plasma treated polyacrylate sized fabrics. The percent desizing ratio (PDR) results showed that more than 99% PDR was achieved after 65s plasma treatment followed by a 5min NaHCO3 desizing.
