Dyeing Properties of the Plasma-Treated Wool Dyed with Lanasol CE Series Reactive Dyes

Wool was treated by air low temperature plasma and dyed with Lanasol CE series reactive dyes. Dyeing properties of the treated wool were studied and compared to the untreated wool. The result showed that the dyeing properties of the low temperature plasma-treated wool were improved obviously, and the dyeing temperature can be reduced. From the measurements of SEM, alkali solubility and water retention rate, it can be seen that the scale layer surface of the treated wool was damaged, and the specific surface and the wettability of the treated fiber was increased. It was these changes that lead to improving dyeing properties of the treated wool.
