The Effect of Different Plasma Treatments on the Pigment Dyeing of Cotton Fabrics

In this paper, the application of glow discharge (low pressure) and dielectric barrier discharge (atmospheric) prior to pigment dyeing of cotton fabric was studied. Different parameters of power and time during the process were also discussed. The dyeing effect after different plasma treatment was analyzed by SEM observations and measurements of the K/S value, levelness and color fastness. The results indicated that the particle diameter of pigment affected pigment dyeing, and the K/S value increased as particle diameter decreased. These two plasma treatments could enhance the properties of pigment dyeing with satisfied color fastnesses. Fabrics treated by plasma should be dyed within 2 hours of plasma treatment to ensure optimum results. The power of atmospheric plasma treatments was relatively high without maintaining a vacuum atmosphere, and it could be processed continuously with high efficiency and K/S value.
