PROBLEM TO BE SOLVED: To provide a low-crimped thick-and-thin false-twisted yarn which has fine moire feeling, is reduced in roughness, and can express soft feeling or the like; and to provide a method for manufacturing the same.SOLUTION: A low-crimped thick-and-thin false-twisted yarn is a thick-and-thin false-twisted yarn in which a single filament forming the false-twisted yarn has thick parts and thin parts in a longer direction. In the low-crimped thick-and-thin false-twisted yarn, the length of each thick part is 1.5 cm or less, the proportion of the thick parts is 5-70%, and an expansion/contraction recovery ratio is 5-35%. Preferably, the cross-sectional deformation of the single filament is 2.0 or less in the low-crimped thick-and-thin false-twisted yarn. Further, preferably, the thick-and-thin ratio of the largest filament and the smallest filament in the cross section of the single filament is 1.2-3.0 in the low-crimped thick-and-thin false-twisted yarn.SELECTED DRAWING: Figure 1 【課題】繊細な杢感を有し、ガサツキが少なくソフトな風合い等を表現できる低捲縮太細仮撚加工糸およびその製造方法を提供する。【解決手段】仮撚加工糸を構成する単フィラメントが、長手方向に太部と細部を有する太細仮撚加工糸であって、前記太部の長さが１．５ｃｍ以下、かつ前記太部の割合が５〜７０％であり、伸縮復元率が５〜３５％である低捲縮太細仮撚加工糸。好ましくは前記単フィラメントの断面変形度が２．０以下である低捲縮太細仮撚加工糸。更に、好ましくは、前記単フィラメントの断面における最大フィラメントと最小フィラメントの太細比が１．２〜３．０である低捲縮太細仮撚加工糸。【選択図】図１
