Use of Plasma Technology for Modification of Textiles

The use of non-thermal, oxygen and argon low-pressure plasmas for modification of cellulose textiles is discussed. The emphasis is given to the characterization of the complex micro-morphology and physical-chemical changes of the textile surface after plasma treatments, as well as on defining the impacts of these changes on the obtained final properties of textile materials treated in this way. SEM and AFM results confirmed the thesis that using oxygen and argon plasmas, two, essentially different, processes of textile surface ablation occurred ; the first is chemical etching and the second physical sputtering. Using the AFM, the fibre surface morphology was estimated at nanoscale. The measurements of the vertical rise of water in fabric sample and the results of the wetting time (vertical test and drop test) indicate the improvement of hydrophilic properties of all tested samples after low-pressure oxygen plasma treatment. The presented results confirm that the low-pressure plasma treatment is an acceptable and appropriate method of textile surface modification and an eco-friendly method at the same time.
