Grundlagenuntersuchungen zur Plasmabehandlung von Cellulosefasern. Grundlegende Aspekte des Up-Scaling des Plasmaprozesses Abschlussbericht

Low pressure plasma treatment of cellulosic fabric lengths was carried out by means of a newly developed vacuum plant that was built up and set into work at industrial working width (1,80 m) and at a working speed (up to 75 m/min) which is typical for textile technology. Working parameters were scaled up by deducing them from lab scale discontinuously operating plants. Hydrophilisation of cotton fabrics was a central point to reach comparable treatment results. Studies comprised optimisation of the large area electrode arrangement, rf power input for the maintenance of plasma, as well as the homogenisation of treatment effect by a defined gas leading system within the vacuum chamber. To suppress the influence of the moisture of textile material a treatment matched IR predrying equipment was set up. A crucial point of investigation was the study of plasmachemical conversion of process gas interacting with the textile sample. Transport conditions of reactive volatile reaction products within the 3 dimensional web structure causes a characteristic pressure dependency. Therefore, own technical solutions were deduced. As a result, a tool is offered to partners of textile industry for testing novel, environmental friendly finishing effects of textiles and introducing them into production.
