Abstract
In this study, the surface of polyester and polyamide fabric were modified by atmospheric pressure glow discharge plasma (APGD) under different operating conditions to improve the hydrophilicity and printability of the fabric. Different plasma treatment gases i.e., air, oxygen (O2), nitrogen (N2), argon (Ar), and water vapor was investigated. The treatments of PET and PA fabrics by aspartic (Asp.) and sulfamic (Sulf.) acid were done after plasma treatment in order to improve their printability for basic and acid dyes. The plasma exposure time has been changed to control the extent of plasma surface modification. The efficiency of the plasma treatment was assessed through wettability, K/S, and fastness properties measurements. Surface characterization was performed through FTIR and SEM detection. It was observed that wettability, and the color strength of printed PET and PA fabrics were significantly improved by all plasma treatments.
