A study of pigment application on atmospheric pressure plasma treated cotton fabric

Cotton fabric was treated with atmospheric pressure plasma under the influence of different degrees of discharge power (130 W, 140 W, 150 W, 160 W, and 170W) and oxygen flow rates (0.2 l/min, 0.3 l/min, 0.4 l/min, 0.5 l/min, and 0.6 l/min). After plasma treatment, the cotton fabric was subjected to pigment dyeing. Experimental results revealed that plasma treatment with increasing discharge power and oxygen flow rate is able to achieve a better water absorbency and hence improve the pigment dyeing ability. In addition, the plasma treatment can improve the crocking performance of the pigment dyed fabric.
