Antibacterial Properties of Lyocell Fabrics Treated using Low-pressure Plasma and Copper(II) Sulphate

Due to the different physical and chemical process that occurs in the interaction of plasma and textile surface, by treatments in plasma it could be affected on the changes of the target properties of textile cellulose material. Such approach has been used in this paper. Treatment of cellulose fabrics using copper (II) sulfate on the samples previously pretreated with Oxygen plasma and followed treated with 0.6 M succinic acid solution (SA) with a catalyst were carried out. After curing process, the process of Argon plasma fixation in order to achieve fixation improvement of succinic acid anhydride on cellulose substrate was carried out. The effects of changes on the level of micro-morphology using modern methods of identification - SEM and AFM techniques were tested, while the changes of chemical surface properties using FTIR-ATR technique were investigated. The effectiveness of such performed treatments was analyzed by microbiological qualitative test (Agar diffusion plate test) on two bacterial species Staphylococcus aureus and Escherichia coli.
