Effect of low temperature plasma treatment on the dyeability of regenerated bamboo/cotton blended fabrics

In this research, regenerated bamboo (viscose)/cotton blended fabrics were treated with low temperature plasma under various treatment conditions (i.e., oxygen flow rate, jet-to-substrate distance, and plasma treatment time) to evaluate how these parameters influenced fabric dyeing properties. It was shown that low temperature plasma treatment can modify polymer surfaces and change the substrate’s properties, such as wettability. In this study, plasma-treated fabrics were dyed with mono-functional and bi-functional reactive dyes to check for changes in CIELAB, ΔE*, and color yield values. The study concluded that color yield of the plasma-treated fabric was better when dyed to a color depth of 3%.
