Abstract
A production process of cellulose fiber is characterized in that tertiary amine N-oxide is used as a solvent for pulp, and a silver-based antibacterial agent and optionally magnetized mineral ore powder are added, followed by solvent-spinning. The cellulose fiber exhibits an excellent long lasting antibacterial effect and serves preferably as medical products such as bandage, gauze, and surgical robes.
