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. ## Claims ### Claim 1 A method of preparing an artificial hair filament, comprising: coating a filament with an antibacterial and antifungal drug, wherein the filament is spun from at least one resin selected from the group consisting of a polyolefin, a polyester and a polyamide, and the coating starts from a lower portion of the filament using a contact-type drug-treating roller, and an upper portion of the filament using an ultrasonic spraying machine. ### Claim 2 (depends on 1) The method of claim 1, wherein the filament is fed by a feed roller, and wound around a winding roller after the filament is coated with the antibacterial and antifungal drug. ### Claim 3 (depends on 1) The method of claim 1, wherein the filament is bent at an angle of 3 to 10° by a tension-adjusting roller before the filament is coated with the antibacterial and antifungal drug. ### Claim 4 (depends on 1) The method of claim 1, wherein the filament coated with the antibacterial and antifungal drug is heat-treated at a temperature of 150 to 200° C. ### Claim 5 (depends on 1) The method of claim 1, wherein the antibacterial and antifungal drug has a concentration of 0.05 to 2% by weight and a viscosity of 10 to 50 cps. ### Claim 6 (depends on 1) The method of claim 1, wherein the ultrasonic spraying machine has an air pressure of 1 to 5 kg/cm2. ### Claim 7 (depends on 1) The method of claim 1, wherein the antibacterial and antifungal drug comprises a nanoparticle component having antibacterial and antifungal properties. ### Claim 8 (depends on 1) The method of claim 1, wherein the antibacterial and antifungal drug comprises a binder selected from the group consisting of a polyurethane-based resin, an acrylic resin, a silicone-based resin, a melamine-based resin, an epoxy-based resin, and a mixture thereof. ### Claim 9 A device for preparing an artificial hair filament, comprising: a feed roller configured to feed a filament; a tension-adjusting roller configured to bend the filament fed from the feed roller at an angle of 3 to 10° in a traveling direction thereof; an ultrasonic spraying machine configured to spray an antibacterial and antifungal drug on the filament passed through the tension-adjusting roller by allowing the spraying to start from an upper portion of the filament; a contact-type drug-treating roller configured to coat the filament passed through the tension-adjusting roller with the antibacterial and antifungal drug by allowing the coating to start from a lower portion of the filament; a heat treatment machine configured to heat-treat the antibacterial and antifungal drug at a temperature of 150 to 200° C.; and a winding roller configured to wind the heat-treated filament. ### Claim 10 An artificial hair filament having a core structure and a sheath structure, wherein the core structure is formed of a filament spun from at least one resin selected from the group consisting of a polyolefin, a polyester and a polyamide, and the sheath structure is formed by coating the filament with an antibacterial and antifungal drug, wherein the coating starts from a lower portion of the filament using a contact-type drug-treating roller, and an upper portion of the filament using an ultrasonic spraying machine. ### Claim 11 (depends on 10) The artificial hair filament of claim 10, wherein the sheath structure occupies 5 to 20% of a filament diameter.
