Dyeing of Oxygen Plasma Treated Wool Fibers with Rhuem Ribes L. Flowers

In this study, the extract of Rhuem Ribes L. flowers was used for dyeing of wool fibers. Oxygen plasma was used as a pretreatment to enhance the dyeability of wool fibers and metal mordant was eliminated from the dyeing process. The surface morphology of the wool fibers before and after plasma treatment was investigated by SEM images. FTIR analysis was employed to study the chemical changes imparted to the wool fibers by plasma treatment. The surface of wool fibers was etched and oxygen containing groups were introduced to the surface of wool fibers. The fastness of the dyed samples to washing and light was measured. The plasma treated samples showed better dyeability as well as good fastness to washing and light.
