Especially environmental friendly methods and application of biopolymers are gaining  importance instead of conventional processes and textile chemicals. In this study, nanochitosan particles were synthesized, applied on  wool fabrics and compared with bulk chitosan in terms of various properties. Ag-loaded chitosan nanoparticles was also synthesized and  examined in terms of its antibacterial activity by different application methods. It has more than 95 % antibacterial effect against gram  positive and negative bacteria. The influences on hydrophilicity, antibacterial activity, dyeing, air permeability, surface morphology and  tensile strength were studied. Enzyme and atmospheric plasma treatments were used both alone and combined treatments before  application of chitosan/nanochitosan to increase their effects. It was noticed that enzyme and plasma treatments showed significant  contributions on chitosan and nanochitosan in all investigated properties. From surface observations, it was seen that especially  combined treatments caused a smoother surface on wool fabrics. Therefore improved hydrophilicity and dyeability properties could be  obtained by ecological methods. As a result of dyeing process, the synergetic effect of enzyme, plasma and nanochitosan treatments led  to 2.5 times higher K/S values than that of untreated fabric. Moreover, all treatments had no detrimental effects on bulk properties of  fabrics. </div>}, number={4}
