Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an acrylic thread manufacturing method capable of stably manufacturing the acrylic thread while suppressing fuzz in steam drawing after spinning.SOLUTION: Steam drawing is provided on a thread comprising acrylic polymer in a drawing device in an acrylic thread manufacturing method. The steam drawing is performed by injecting a low pressure steam in the drawing device and reheating the low pressure steam in the drawing device during the steam drawing. It is preferable that an atmospheric temperature is 120°C or higher in the drawing device and the injected low pressure steam temperature is 160°C or less. It is also preferable that a filament number of the acrylic threads is 100 or more.SELECTED DRAWING: Figure 2 【課題】アクリル系糸条の製造方法において、紡糸後にスチーム延伸する際の毛羽の発生を抑え、安定して生産できる方法を提供すること。【解決手段】アクリル系重合体からなる糸条を延伸装置内でスチーム延伸するアクリル系糸条の製造方法であって、延伸装置内に低圧スチームを吹き込み、延伸装置内にて該低圧スチームを再加熱しつつスチーム延伸するアクリル系糸条の製造方法。さらには、延伸装置内の雰囲気温度が１２０℃以上であることや、吹き込む低圧スチームの温度が１６０℃以下であることが好ましい。またアクリル系糸条のフィラメント数が１００本以上であることが好ましい。【選択図】図２
