PROBLEM TO BE SOLVED: To obtain a slub-toned composite yarn rich in color variation, having soft and silky touch feeling, and good in bundleability. SOLUTION: This slub-toned composite yarn is so designed that a false-twist crimp-free shrinkable multifilament yarn is integrally wrapped around false-twist thick-and-thin multifilament yarn so as to form singly wrapped portions and triply wrapped portions alternately. The false-twist yarn constituting the singly wrapped portions has a gentle twist, while the false-twist yarn ctonstituting the triply wrapped portions has a denser twist in the twist direction differing from that for the former false-twist yarn and also has continuous flex portions in the longer direction of the yarn. This composite yarn is obtained by inserting a shrinkable multifilament yarn as sheath yarn into the untwisted area of the thick-and-thin multifilament yarn as core yarn fed at an overfeed rate of 15-50% being under false twisting by a two-heater false twister, followed by wrapping into integration.
