Abstract

A melt spinning apparatus has an apparatus body, and the apparatus body includes a spinning nozzle through which a molten resin is extruded into a filament, a primary air channel for directing primary airflow to the filament of the molten resin extruded from the spinning nozzle, and a secondary air channel for directing secondary airflow to the filament at a position downstream of the primary air channel. A part, which is closer to the spinning nozzle, of a wall of the secondary air channel that defines an air exit of the secondary air channel is chamfered to straighten the secondary airflow.
