Continuous dyeing of wool fabric containing polyamide fibre and modified by plasma glow discharge

Treatment with low-temperature plasma is one of the most economical and effective methods of modifying the surface of different materials. The continuous (pad-steam) method of dyeing wool fabric containing 10% polyamide fibre (capron) was investigated. Samples dyed by the continuous method were almost the same as samples dyed with the intermittent method with respect to resistance to dry and wet friction and perspiration. Dyeing worsted fabric with a low polyamide fibre content undergoing plasma chemical treatment with the continuous method is thus expedient, since it allows obtaining uniform coloring and is economically advantageous.
