Summary: In this paper, the effects of low temperature plasma (LTP) treatments on the dyeing properties of the wool fibres were studied. The wool fibres were treated with oxygen plasma and three types of dyes commonly used for wool dyeing, namely: (i) acid dye, (ii) chrome dye and (iii) reactive dye, were used in the dyeing process. For acid dyeing, the dyeing rate of the LTP‐treated wool fibre was greatly increased, but the final dyeing exhaustion equilibrium did not show any significant change. For the chrome dyeing, the dyeing rate of the LTP‐treated wool fibre was also increased, but the final dyeing exhaustion equilibrium was only increased to a small extent. In addition, the rate of afterchroming process was similar to the chrome dyeing process. For the reactive dyeing, the dyeing rate of the LTP‐treated wool fibre was greatly increased, and the final dyeing exhaustion equilibrium was also increased significantly. With such results, one could conclude that the LTP treatments improve the dyeing behaviour of wool fibres in different dyeing systems. SEM picture of an untreated wool fibre.
