Influence of Processing Parameters on Surface Wettability Improvement of Wool Fabric Treated by Atmospheric Pressure Plasma Jet
Atmospheric pressure plasma jet (APPJ) is different from vacuum plasma. The vacuum plasma works in a vacuum system. The APPJ works in an open system in which plasma is produced between the capacities coupled electrodes and then ejected from the every pore in nozzle to form plasma jet and the substrate is not completely contacted with the plasma jet. In this study a woven wool fabric was treated under different conditions such as different nozzle to substrate distance, different treatment time and different oxygen content to see how these processing parameters influenced the APPJ treatment effect. The water absorption time and the diffusion size were used to determine surface wettability improvement. After APPJ treatments, scanning electron microscopy analysis showed that fiber surface morphological change occurred; the water absorption time was also reduced. When the treatment time was increased, the treatment effect was enhanced. When the nozzle to substrate distance and the oxygen content was increased, the treatment effect was increased and then decreased. Therefore adequate APPJ processing parameters have to be carefully selected for the best results for evenly treating fabric surface.
