Sažetak:
The present paper describes efficiency of the low-pressure plasma process for improving of deposition process on chemical-physical activated cellulose fabric surfaces. The surface of cellulose substrates was pre-treated with O2 plasma followed by acrylic acid (AAc) as monomer in plasma polymerisation process with surface of raw cotton fabrics in continuous treatment process was used (O2/AAc). AAc as monomer was applied on the fabric surface using PE-CVD process. Modifications of cellulose fibres were studied in respect to surface effects by means of SEM microscopy while the chemical effects of plasma treatment were studied using X-ray photoelectron spectroscopy. Results indicate that the surface of the cotton fibres treated with AAc was cleaner and smother with micro-fibrils visible along to fibre axis, what is in correlation with results of hydrophilic properties of O2/ AAc treated samples. According results of XPS spectra, oxygen plasma certainly changed the chemical surface structure of tested cotton whereby the deposition of the AAc nano-layer on the fibre surface was enabled.
