Size removal of PVA with various moisture content via atmospheric pressure plasma jet
Atmospheric pressure plasma jet (APPJ) was employed to desize poly (vinyl alcohol) on cotton fabric. As indicated by weight loss analysis, plasma treatment could effectively remove some of PVA size on cotton fabrics especially for PVA film with 98% RH. Dissolution analysis showed a higher percent desizing ratio (PDR) on PVA sized fabric with 10% RH than that with 98% RH. After 1 min plasma treatment, the fiber surface was almost as clean as that of unsized fabric followed by a hot wash at a temperature of 60℃ from SEM pictures. In addition, the hygroscopicity of plasma treated PVA films was improved in the first few minutes but reduced after longer absorption time.
