description PROBLEM TO BE SOLVED: To inhibit the turbulence of the accompanying air flow occurring near the inlet of the heating chimney to suppress the yarn sway thereby improving U%, unevenness in dyeing, running condition and yarn physical properties. SOLUTION: This polyester fiber-manufacturing equipment comprises the cooling unit 4 that blows cooling wind to a multi-filament yarn of extruded polyester to cool the yarn lower than the glass transition point, the heating chimney 5 that heats the extruded, once cooled yarn under non-contact conditions and draws the yarn and the winder 3 for taking up the drawn yarn at a speed of more than 3,000m/min. An air flow-straightening member 4a is set to straighten the flow of the cooling air blown from the cooling unit 4 to the yarn-running direction. Further, the inlet 4b for the cooling air is opened to introduce the air into the heating chimney 5 communicating to the yarn inlet on the upper part of the heating chimney 5.
