Formation of Hydrophobic and Water-Repellent Surface on Polyester Fibers using Ar/Hexamethyldisiloxane Plasma at Atmosperic Pressure

In this study, surface modification of polyester fibers with high water repellency was obtained by plasma treatment. Polyester fibers with water repellency were treated with atmospheric pressure middle-frequency (MF) plasma system using Ar and hexamethyldisiloxane (HMDSO). Ar gas has been used as the carrier gas. The surface morphologies of plasma-treated fibers were characterized by scanning electron microscopy (SEM). The Fourier transform infrared (FTIR) spectrometry was carried out to analyze the chemical composition of the polymer surface.
