棉织物的表面通过电晕等离子体处理和/或通过用表卤代醇对整个纤维进行阳离子化来进行功能化。通过润湿性研究、X 射线光电子能谱 (XPS)、扫描电子显微镜 (SEM) 以及异双功能活性染料的染色研究，分析了两种处理单独和组合的效果。等离子体通过表面功能化改善了织物的润湿性能、染浴的吸尽性和 K/S-corr。棉花的阳离子化大大增加了染浴的吸尽率，并显着改善了 K/S-corr。阳离子化之前的等离子体处理增加了织物的浸渍，但是两种处理对染色参数的影响仅在柱水上升中相加，并且通常通过用表卤代醇进行阳离子化获得的效果占主导地位。从棉纤维的表面功能化角度讨论了两种处理之间的差异。
The surface of cotton fabrics was functionalized through corona plasma treatments and/or by cationising the whole of the fibre with an epihalohydrin. The effects of both treatments, individually and in combination are analyzed through wettability studies, by X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM), and also by dyeing studies with an hetero bis functional reactive dye. Plasma improved wetting properties, exhaustion of the dyebaths and K/S-corr of the fabrics through surface functionalisation. Cationising of the cotton highly increased the exhaustion of the dyebaths and produced a dramatic improvement in K/S-corr. Plasma treatment previous to cationising increased the impregnation of the fabrics, but the effects of both treatments on dyeing parameters are additive only in column water rise and generally the effects obtained by cationising with the epihalohydrin prevail. The differences between both treatments are discussed in terms of surface functionalisation of the cotton fibres.
