A plurality of monofilaments is drawn out at an appropriate speed, dried and heated. Then a property enhancing agent containing a metallic salt, alcohol, optional solvent and optional additional functional agent, such as a hygroscopic agent, ultraviolet protecting agent, or resist agent, etc. is applied onto the surface of the filaments which are melted and flame bonded to each other. Multi-filaments are formed with spaces therebetween in which the functional agent remains inserted.
