Plasma à pression atmosphériqueUn plasma à pression atmosphérique (ou plasma à PA ou plasma froid) est le nom donné à une catégorie spéciale de plasma pour lequel la pression approche celle de l’atmosphère.
Le plasma à pression atmosphérique marque une nette différence avec le plasma basse et haute pression. En effet, contrairement à ces derniers aucune enceinte de traitement n'est nécessaire. Ce type de plasma peut donc être utilisé directement sur ligne de production, évitant ainsi l'utilisation de vide qui est extrêmement onéreuse.

Traitement coronaIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In this study, investigations were performed on the effect of atmospheric pressure plasma modification after the retanning process on sheep leathers and wastewater of the processes. The plasma treatments of the leather samples were carried out with an argon containing corona discharge at atmospheric pressure. Argon atmospheric pressure plasma (APP) activation was applied to the crust sheep leather surface with different times (0, 3, 6, 9 sec/cm2). After argon APP application, the crust sheep leathers were processed by traditional retannage. The surface properties of the treated sheep leathers were characterised by scanning electron microscopy (SEM) and an atomic force microscopy (AFM). The chemical composition of the leather surfaces was evaluated by ATR-FTIR and the surface state of the leathers was determined by contact angle measurements. The discharged chrome retanning and retanning wastewaters at the end of the processes were examined in order to determine the differences in the wastewater in terms of COD, BOD5, conductivity, turbidity, pH, salinity, total dissolved solids content (TDS) and total chromium content analyses.

Traction (mécanique)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Chrome tanned crust leathers were treated with atmospheric pressure plasma with argon flows at different times. The leather was then dyed with acid and metal complex dyes. The dyestuff concentration in the exhausted dye bath, CIE lab color analysis, hydrophilicity, FTIR spectra and SEM images were compared for 0, 2.1, 4.2 and 6.4 sec/cm2 durations of plasma. In addition, various physical properties such as rubbing fastness, tear loading and tensile strength were also examined to see the effects of increased duration of the plasma process. The presence of ions that appeared during this process in an atmospheric environment was determined by OES. The best results were obtained from leather subjected to 6.4 sec/cm2 of argon gas atmospheric pressure plasma. Note de contenu : - MATERIALS

Vêtements en cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this study the effect of argon atmospheric pressure plasma on the finishing process of garment leathers was investigated. The argon atmospheric pressure plasma (APP) activation was applied to the garment leathers' surfaces for different treatment times (0, 3, 6 and 9 sec/cm2). After argon APP application, the garment leathers were produced by traditional finishing process. The surface properties of the treated leathers were characterised by scanning electron microscopy (SEM). The elemental and chemical composition of the leather surfaces was assessed by XPS (X-ray photoelectron spectroscopy) and FTIR (Fourier Transform Infrared Spectroscopy) analysis, respectively. The surface states of the leathers were evaluated by contact angle measurements and physical properties of the leathers such as tensile strength, elongation at break, double edge tear load, thickness, colour and rubbing fastness were examined. According to the obtained results, it was found that the hydrophilic property of the plasma treated garment leathers is increased. In the physical properties results, a slight increase in tensile strength, tear load and elongation at break were observed being in parallel with the increase in plasma duration. In addition, plasma modification improved the colour and rubbing fastness of the leather alter finishing. The best results were obtained for 9 seconds of argon plasma treatment. It was concluded that non-destructive modification of leather surface leading to better physical and fastness properties could be achieved by appropriate gas selection and sufficient application time.
