Abstract
An artificial hair filament having a core/sheath structure is provided. The artificial hair filament has excellent antibacterial and antifungal effects since antibacterial and antifungal nanoparticles are included in the sheath structure of the artificial hair filament. Here, the antibacterial and antifungal effects can last for a long period of time. A contact-type drug-treating roller and an ultrasonic spraying machine can be used to provide the artificial hair filament with the antibacterial and antifungal effects. In the artificial hair filament, the sheath structure is formed so that the sheath structure occupies 5 to 20% of an entire filament diameter, thereby exhibiting desirable antibacterial and antifungal effects. Therefore, degradation of the antibacterial properties and antifungal properties with time can be prevented.
