Sažetak
In this paper low-pressure (LP) plasma system type Nano LF-40kHz for treatment processes of the cotton samples surface at defined parameter conditions was used. Surface of cotton fabrics were activated using oxygen plasma, and treated with succinic acid (SA) and sodium hypophosphite monohydrate (SHP) as cellulose cross linking agents. At the end of treatment, fixation process for better cross linking effects between carboxylic groups of succinic acid and cellulose functional groups were carried out using two processes: curing process at high temperature and argon (Ar) plasma fixation at room temperature. The purpose of this research is mainly to evaluate how the different plasma processes influence on the better fixation of carboxylic groups of succinic acid with the cellulose functional groups. It can be presumed that using plasma medium and dicarboxylic acid have proved to be the effective system to give a great number of chemical species on the treated surface, which can act as active centers on the cellulose substrate capable to create new plasma-chemical reactions using different chemical agents, e.g. metal ions. The changes in chemistry of treated cotton samples were analyzed using FTIR-ATR technique. The changes of surface appearance of cotton fibre samples were analysed using Scanning Electron Microscopy (SEM). The changes of mechanical properties were performed using Strength Tester. The impacts of treatments on the hydrophilic properties were analysed using drop test.
