Penetration depth of atmospheric pressure plasma surface modification into multiple Layers of polyester Fabrics
Surface and Coatings Technology, 2007Co-Authors: C. X. Wang, Yu Ren, Y. P. QiuAbstract:Penetration depth of plasma surface modification of polyester Fabrics was investigated. An eight-Layer stack of woven polyester Fabrics was exposed to a helium/oxygen atmospheric pressure plasma jet. Water-absorption time was used to evaluate surface hydrophilicity on the top and the bottom sides of each Fabric Layer and water capillary rise height was recorded as a measure of modification effectiveness for each Fabric Layer. Surface morphology and chemical compositions of each Fabric Layer in the stack were analyzed by atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). After atmospheric pressure plasma jet treatment, the top side of the polyester Fabric became more hydrophilic. The penetration of plasma surface modification into the Fabric Layers was deeper for Fabrics with larger average pore sizes. It was found that helium/oxygen atmospheric pressure plasma jet was able to penetrate 8 Layers of polyester Fabrics with pore sizes of 200 μm.

Influence of atmospheric pressure plasma treatment time on penetration depth of surface modification into Fabric
Applied Surface Science, 2008Co-Authors: Chongbin Wang, Yu Ren, Yan Liu, Yiping QiuAbstract:In order to determine the relationship between the treatment duration of atmospheric pressure plasma jet (APPJ) and the penetration depth of the surface modification into textile structures, a four-Layer stack of polyester woven Fabrics was exposed to helium/oxygen APPJ for different treatment durations. The water-absorption time for the top and the bottom sides of each Fabric Layer was reduced from 200 s to almost 0 s. The capillary flow height for all Fabric Layers in the stack increased linearly with the treatment duration but the rate of increasing reduced linearly with the Fabric Layer number. A model for the capillary flow height as a function of treatment duration and the Layer number was established based on the experimental data and the maximum penetration depth of the APPJ was predicted for the polyester Fabric. The improved wettability of the Fabrics was attributed to the enhanced surface roughness due to plasma etching and the surface chemical composition change due to plasma-induced chemical reaction as detected by scanning electron microscopy and X-ray photoelectron spectroscopy, respectively. The surface roughness and the surface chemical composition change diminished as the Fabric Layer number increased.
