Abstract
A method of manufacturing nano-fiber non-woven fabrics is provided. The method comprises preparing a polyurethane solution by dissolving polyurethane in an organic solvent, producing an electrospinning solution by adding far infrared ray emitting particles, antibacterial inorganic particles, and deodorization inorganic particles to the polyurethane solution, and electrospinning the electrospinning solution to form the nano-fiber non-woven fabric. The far infrared ray emitting particles may be obtained by adding a metal oxide to ceramics and sintering the metal oxide-added ceramics. The antibacterial inorganic particles may be obtained by impregnating a zirconium-based carrier with silver ions. The deodorization inorganic particles may be obtained by impregnating a zirconium-based or a silica oxide-based carrier with an amine-based compound.
