N/A Chitosan fiber spun through circular nozzle was immersed into alginate solution to enhance mechanical properties of the fiber for suture application. The tensile strength of the chitosan fiber increased with an increase of molecular weight and concentration of the chitosan. The dry tenacity of chitosan fiber (cps 15.7) was enhanced by treatment with alginate solution from 0.56 g/d to 1.71 g/d due to the formation of polymeric electrolyte complex between chitosan as polycation and alginate as polyanion. The optimum condition of treatment concentration and time of alginate to enhance mechanical properties of chitosan fiber was 0.5 wt% and 12 hrs, respectively. The morphology of the chitosan fiber after treatment with alginate showed smoother than that of chitosan fiber only.
