This study focused on the usage of plasma treatment for the modification of fibre surfaces to achieve the dyeing of mohair fibres at lower temperatures without causing a decrease in dyeexhaustion. The study was carried out using different gases under various powers and times. The effect was assessed in terms of colour, and the test samples were also evaluated using scanning electron microscopy (SEM). The optimum conditions of plasma treatment for improving mohair fibre dyeability are treatments carried out using Ar gas at 140 W for 60’’. According to the results of the experiments, it can be concluded that plasma treated mohair fibres can be dyed at lower temperatures (90 °C) and for shorter times (1 h instead of 1.5 h) with reactive dye without causing any decrease in colour yield. Dyeing kinetics were also researched in the study, and it was demonstrated that the rate constant and standard affinity of the plasma treated sample increased.
