Effect of Atmospheric Pressure Plasma Treatment/Followed by Chitosan Grafting on Antifelting and Dyeability of Wool Fabric

摘要

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.
