The application of He/O2 atmospheric pressure plasma jet and ultrasound in desizing of blended size on cotton fabrics

► The removal of the blend of PVA and starch phosphate treated by plasma and ultrasound is studied. ► The change of surface morphology and surface chemical composition of blends treated by plasma were studied. ► The influence of plasma and ultrasound treatment on the percent desizing ratio (PDR) is investigated, respectively. ► The capillary rise height is used to study the wicking properties after plasma and ultrasound desizing.
