Argon Plasma Treatment for Improving the Physical Properties of Crosslinked Cotton Fabrics with Dimethyloldihydroxyethyleneurea-Acrylic Acid

Abstract

In this study, argon plasma treatment was added to the traditional pad-dry-cure process between dry and cure treatment. This new process was assign as pad-dry-plasma-cure. The crosslinking agent was a mixture of dimethyloldihydroxyethyleneurea (DMDHEU) and acrylic acid (AA). The results showed that argon plasma treatment could increase the bonded crosslinking agent (nitrogen content). Dry crease recovery angle (DCRA), wet crease recovery angle (WCRA) and tensile strength retention (TSR) of pad-dry-plasma-cure-finished fabrics were higher than that of traditional pad-dry-cure finished fabrics at a given value of nitrogen content. Additionally, it was found that the number of crosslinks per anhydroglucose unit (CL/AGU) and the length of crosslinks of pad-dry-plasma-cure-finished fabrics were higher than that of traditional pad-dry-cure-finished fabrics at a same resin concentration in the pad bath. DCRA, WCRA and TSR values of pad-dry-plasma-cure-finished fabrics were higher than that of pad-dry-cure-finished fabrics at a same CL/AGU value. The pad-dry-plasma-cure process is thought to be excellent for improving the physical properties and decreasing the formaldehyde release of the finished cotton fabrics.
