Pressure Dependence of Helium DBD Plasma Penetration Into Textile Layers

Plasma treatment changes the outermost layer of a material without interfering with the bulk properties. However, textiles are several millimeters thick and need to be treated homogeneously throughout the entire thickness. In this paper, the dielectric-barrier-discharge treatment in He of three different textile layers is studied for several medium pressure values, and images of the discharge footprints are presented to demonstrate the pressure effect on plasma penetration.
