Abstract
Effect of chitosan on antifelting and dyability of dielectric barrier discharge (DBD) pretreated wool fabric were evaluated. We have used a DBD, working in an atmospheric pressure air for pretreatment of wool fabric. The chitosan was applied to pretreated wool fabrics by using pad-dry cure technique. The anti-felting properties of the wool samples were studied and it was shown that the shrink resistance and anti-felting behavior of the wool had been significantly improved by the DBD pretreatment followed by chitosan grafting. In addition, dye ability of wool fabrics after plasma/chitosan treatment is improved. Some analytical skills such as Fourier transform infrared spectroscopy and scanning electron microscope were used to characterize the different aspects of the treated fabric.
