Zusammenfassung:	To provide a method for stably producing a high hollow ratio fiber having a hollow ratio of 40% or more.SOLUTION: A high hollow polyester fiber having a hollow ratio of 40 to 90% is obtained, utilizing the hollow part expansion effect of a hollow un-stretched fiber by low tension flow stretching, by subjecting un-stretched yarns having a hollow ratio of 15 to 35% to flow stretching at a temperature higher than the glass transition temperature of polyester under a low tension of 0.1cN/dtex or lower.SELECTED DRAWING: Figure 1 【課題】中空率４０％以上の高中空率繊維を安定して生産するための製造方法を提案する。【解決手段】低張力フロー延伸による中空未延伸繊維の中空部膨張効果を利用し、中空率１５〜３５％の未延伸糸をポリエステルのガラス転移温度より高い温度で０．１ｃＮ／ｄｔｅｘ以下の低張力下でフロー延伸することで、中空率４０〜９０％の高中空ポリエステル繊維を得る。【選択図】図１
