Abstract:
1. A method of manufacturing nano-fiber non-woven fabrics comprising: preparing a polyurethane solution by dissolving polyurethane in an organic solvent; adding far infrared ray emitting particles, antibacterial inorganic particles, and deodorization inorganic particles to the polyurethane solution to produce an electrospinning solution, wherein the far infrared ray emitting particles are obtained by sintering a combination of one or more a metal oxide and one or more ceramic materials, the antibacterial inorganic particles are obtained by impregnating a zirconium-based carrier with silver ions, and the deodorization inorganic particles are obtained by impregnating a zirconium-based or a silica oxide-based carrier with an amine-based compound; and electrospinning the electrospinning solution to form the nano-fiber non-woven fabric, wherein the electrospinning solution comprises about 2 to 4 wt % of the far infrared ray emitting particles, about 1 to 4 wt % of the antibacterial inorganic particles, about 2 to 6 wt % of the deodorization inorganic particles, based on total weight of the electrospinning solution.
