The dyeing properties of wool fibre treated with low‐temperature plasma (LTP) were investigated kinetically and thermodynamically. Three non‐polymerising gases, namely oxygen, nitrogen and a 25% hydrogen/75% nitrogen gas mixture, were used for the LTP treatment. It was found that the dyeing rate, dye uptake, standard affinity, heat of dyeing, entropy of dyeing and activation energy of diffusion were improved after the treatment.
