Étude des traitements par plasma à pression atmosphérique : applications à l'industrie textile

Abstract : Surface properties of textile are important factors for the end-use materials properties. These surface properties determine the hydrophilic and hydrophobic behaviour of the materials and also theirs padding and coating adhesion as well as their dyeing behaviours. Atmospheric plasma treatments seem to be a good way to treat quickly, cheaply and ecologically polymeric surfaces. First, the impact of atmospheric air Dielectric Barrier Discharge (D.B.D.) plasma treatments were studied on a poly(propylene) film. A surface oxidation and a roughness modification were observed. The ageing of these modifications was follow. Then, according with the previews results, plasma treatments were used to treat various poly(ethylene terephthalate)textiles (Film, nonwovens, fabrics). The plasma treatment influences on the surface energy, capillarity and adhesion properties were checked for each textile. This work shows that the polymer chemistry, the porosity and the air permeability have an influence on the final properties and on the plasma treatment power needed to reach them. Plasma treatments were also used as a pre-treatment before dyeing or fluoro-polymer padding processes
