Abstract

The plasma treatment is used, widely, to impact the surface characteristics and improves the coloration properties of silk fabrics. Here, the dielectric barrier discharge plasma type is implemented where, both the untreated silk and plasma treated one alone and with nanoparticles mixtures of Zinc Oxide (ZnO) and Titanium dioxide (TiO2) with various percentages have been characterized. This investigation is characterized by wet- out time, scanning electron microscope (SEM), FTIR, color intensity (K/S) and fastness properties. The investigation results using the FTIR indicates that plasma treatment has increased the hydroxyl functional group while, the wet- out time results of plasma NPs-treated silk fabrics identified to what extent the hydrophilic properties were improved and confirmed via the contact angle measurements which is too close to zero. The tensile strength measurement is also confirmed the surface properties enhancement. The printability of treated silk with natural dyes as well as antibacterial properties are improved
