Graft co-polymerization of acrylic acid onto the linen surface induced by DBD in air

Linen fabric is an excellent material due to its wettability, permeability to air and electrostatic resistance. However, the difficulty of dyeability is a main disadvantage for its practical applications. Graft co-polymerization of acrylic acid (AAc) onto the linen surface induced by dielectric barrier discharge (DBD) in air can effectively improve the dyeability. The paper mainly studied the ability of graft co-polymerization AAc onto linen surface by DBD treatment in air. The AAc grafted on linen surface was characterized by differential thermal analysis, scanning electron microscopy and Fourier transform infrared attenuated total reflection spectroscopy. The grafting degree was measured by visible absorption spectroscopy. The effects of plasma treatment time, grafting time, grafting temperature and grafting solution concentration on the grafting degree were studied and discussed.
