Spinning of nanocellulose/chitosan hybrid fiber was successfully achieved using wet spinning technique. Rheocrysta<sup>®</sup>, TEMPO oxidized cellulose nano-fibers (TOCN) was used as nanocellulose obtained from DKS Co. Ltd. The TOCN in various concentration of sodium hydroxide solution was used as a coagulation solution. Chitosan was used as dope solution for the spinning. Thus, the dope solution was coagulated by sodium hydroxide as well as TOCN thus the nanocellulose/chitosan hybrid fiber was obtained. Zeta-potential measurement revealed the surface condition of nanocellulose/chitosan hybrid fibers. Mechanical properties of the nanocellulose/chitosan hybrid fibers were increased with increasing the concentration of TOCN in the bath. Swelling character of the nanocellulose/chitosan hybrid fiber was suppressed compared to the chitosan alone fiber suggesting the more rigid structure in nanocellulose/chitosan hybrid fiber. Moreover, ammonium ion and protein adsorptions were also investigated.
