Chitosan is a natural and non-toxic polymer which can be used as a multifunctional, e.g. antimicrobial or anti-wrinkle, agent on cotton fabrics. However, due to the lack of strong bonding forces between two polysaccharides, chitosan coating on cotton has poor durability. To provide efficient and irreversible chitosan adsorption on cotton substrate, it is required to build appropriate binding sites and to activate the substrate material properly. For this purpose, plasma treatment can be a promising method as it can activate the surface of the cotton fabric and improve the adsorption of chemicals in a completely harmless procedure. In this study, we investigated the effect of atmospheric pressure plasma treatment on adsorption of chitosan onto the cotton fabric. The purpose of the study was to investigate to which extent adsorption of chitosan on cotton can be improved by helium plasma treatment. Fibre surface and adsorption of chitosan were characterized by X-ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared (FTIR) spectroscopy. Changes in hydrophobicity of fabric`s surface and fibre morphology were evaluated using contact angle method and scanning electron microscopy (SEM), respectively. The results from XPS showed an increase in the C=O bonds on cotton fabrics oxydised by helium plasma treatmnets, confirming the formation of aldehyde groups in cellulose. The characteristic absorbance band of chitosan, amide II (N-H bending vibration) showed an enlargement for all fabrics treated with helium and chitosan, as assesed by FTIR. The absorbance peaks of CH2 stretching vibrations, which confirm chitosan existence, were stronger for all treated fabrics compared to the untreated control. While the plasma only treated fabric surface was very hydrophilic, the surface became hydrophobic after chitosan coating.
