In this study, superhydrophilic polyester textiles through atmospheric pressure plasma treatment, targeting their use in oil-water mixture separation was developed. The effect of fabric treatment and grammage variations—79, 103, and 125 g m−2—on the efficiency of separation, flux rates, and overall performance of the separation column was evaluated. The surface properties of the fabricated polyester fabrics were evaluated using scanning electron microscopy and energy-dispersive X-ray spectroscopy to analyze their topographical and elemental composition. These analyses indicate APP treatment creates surface micropits and evenly distributes active oxygen, enhancing polyester's hydrophilicity without altering its elemental makeup. The investigation further explored the antifouling capabilities and durability of both the modified and unmodified textiles. Remarkably, the research revealed that utilizing a dual-layer arrangement of the modified textile, possessing a grammage of 125 g m−2, resulted in a flux recovery ratio of 98.66 %. Additionally, the application of a quintuple-layer structure of the modified fabric markedly augmented the separation efficacy to an excess of 99.90 %. Impressively, this high level of efficiency was maintained at 92.20 % even after five usage cycles, a testament to the increased hydrophilicity imparted by the atmospheric pressure plasma processing. Therefore, atmospheric pressure plasma-treated polyester fabrics have shown a promising behavior in the field of oil-water mixture separatrtion.
