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.

Barrier Discharge Plasma

The effect of atmospheric pressure dielectric barrier discharge plasma treatment on desizing polyvinyl alcohol (PVA) on polyester fabric was discussed as compared desizing with alkali through a combination of desizing rate, field scanning electron microscopy and strength test. The dyeing properties of polyester fabrics treated with atmospheric plasma have also been studied. The results show that plasma treatment can improve desizing rate, surface color depth and dye-uptake for polyester fabric.

In this study, we report on the investigation of influence of air atmospheric pressure dielectric barrier discharge on polyimide (Kapton) films. It is shown that plasma treatment causes a significant increase of Kapton wettability that is connected with alterations of its chemical composition (oxidation) induced by dielectric barrier discharge. Observed variations in the wettability of Kapton were also found to be accompanied by changes in the dynamics of water droplets drying on plasma-treated Kapton, namely by the reduction of the constant contact angle phase of the droplet drying. This effect may be ascribed to the higher surface heterogeneity of plasma-treated Kapton that causes pinning of the edges of drying droplet on the Kapton surface. Finally, the differences in wettability induced by the plasma treatment led to a different way, how the water condensates on the Kapton surface: while the condensing water forms large amount of small droplets on untreated Kapton, much bigger water structures were found on the Kapton exposed to atmospheric plasma.

Dielectric Barrier

An environmentally friendly approach, which consists in coupling a dielectric barrier discharge (DBD) based atmospheric plasma treatment with a coating of an aqueous phase polyurethane dispersion (PUD) containing blocked polyisocyanates, is proposed to improve the adhesion of a thermoplastic polyurethane (TPU) film onto a poly-(ethylene terephthalate) (PET) textile fabric. In this study, a screening digital design of experiment plan (DOE) was developed to determine the influence of process parameters on the adhesion between film and fabric and to evaluate the best possible adhesion value. The process parameters considered are: the dielectric barrier discharge power, the speed of the fabric undergoing the treatment, the concentration of polyisocyanates (NCO) in the PUD and the air gap. The adhesion was measured by a peeling test and further scanning electron microscope observations were carried out. Results showed that an increase of both the processing power and the NCO content in PUD, as well as the decrease in the DBD speed, had a positive effect on the adhesion. In addition, X-ray photoelectron spectroscopy and contact angle measurements demonstrated an increase in the oxygen/carbon atomic percentage ratio between the reference fabric and the treated fabric. Thus, the calibrated oxidation of the PET treated with DBD plasma treatment leads to a greater chemical and physical interaction with the TPU film, which results in better film-fabric adhesion.
