Plasma induced nano-finish for multifunctional properties on cotton fabric

Abstract

Atmospheric pressure dielectric barrier discharge plasma treatment for fabric surface activation to facilitate deposition of nano silicon oxide, and nano-titanium dioxide onto cotton fabric has been studied. It is aimed to study the possibility of engineering a multifunctional cotton fabric. The treated fabric is evaluated for ultraviolet protection factor (UPF), antimicrobial activity, and flame retardancy as a functional finish. Surface morphology (SEM), thermo-gravimetric analysis (TGA), and mechanical properties are also studied. Scanning electron microscopy shows deposition of nano particles onto the fabric. He-O₂ plasma pre-treatment improves the flame retardancy, UPF, antibacterial activity and thermal stability of the samples as compared to untreated samples. In order to improve the wash fastness of the finish, HMDSO plasma polymer is deposited on the surface of the finished fabric which acts as a barrier layer and imparts durable finish on cotton textiles.
