Application of corona discharge on desizing of polyvinyl alcohol on cotton fabrics

, 2009
In this study, corona discharge was applied to optimize the desizing of polyvinyl alcohol (PVA) on cotton fabric. The weight of sized fabric decreased slightly when the PVA sized fabric was treated by corona discharge.
