This study is anchored on the use of an eco-friendly effective plasma technique and cationization treatment to improve the hydrophobic nature of polyester (PET) fabric by incorporating hydrophilic functional groups onto the PET surface. The PET surface was initially treated with three different plasma gases prior to cationization treatment with quaternary ammonium salt (Quat 188). Madder roots were used, to produce natural dyes for the green coloration of PET fabrics in both dyeing and printing processes. The color strength (K/S) was measured to study the influence of both plasma gases and the cationization treatment on the coloration of PET fabric. Exposure to nitrogen plasma gases prior to the cationization treatment showed promising results for efficient PET coloration, resulting in the selection of nitrogen as a working gas at a flow rate of 3 l/min. The results also demonstrated that by combining the nitrogen plasma technique and cationization treatment, PET fabric with a highly effective surface was obtained, resulting in improved coloration, wettability, tensile strength, and roughness properties.
本研究采用环保有效的等离子体技术和阳离子化处理，通过在 PET 表面引入亲水性官能团，改善聚酯（PET）织物的疏水性。在阳离子化处理用季铵盐（Quat 188）处理之前，先对 PET 表面进行三种不同的等离子体气体处理。采用茜草根，为 PET 织物的染色和印花过程提供绿色环保的天然染料。测量颜色强度（K/S），研究等离子体气体和阳离子化处理对 PET 织物着色的影响。阳离子化处理前暴露于氮气等离子体气体显示出高效 PET 着色的有希望的结果，导致选择氮气作为工作气体，流速为 3 l/min。结果还表明，通过结合氮气等离子体技术和阳离子化处理，可以获得具有高效表面的 PET 织物，从而改善着色、润湿性、拉伸强度和粗糙度性能。
