    Abstract: A melt spinning apparatus includes an apparatus body and a nozzle for extruding melted resin, a primary hot air passage formed around the nozzle, and a secondary hot air passage formed in a zone outside of the primary hot air passage, which are formed in the apparatus body. The primary hot air passage discharges primary hot air onto fibers of the melted resin extruded from the nozzle. The secondary hot air passage discharges secondary hot air to maintain the temperature of the primary hot air. The discharge angle of the secondary hot air from the secondary hot air passage is set in a range of 0° to 50° with respect to the direction of the melted resin extruded from the nozzle. The secondary hot air forms an air curtain that blocks the atmospheric air.
