PROBLEM TO BE SOLVED: To provide a composite textured yarn giving woven and knit goods abundant in soft feeling, flare, nerve, repulsion, actually free from producing fluff, and having silky or spun feeling and an apparatus for manufacturing the same. SOLUTION: This composite textured yarn comprises at least two constituent yarns A and B having false twist and crimp, the two constituent yarns have difference in shrinkage percentage, and the monofilament comprising the constituent yarn B having larger shrinkage percentage has gradually changing thick parts and thin parts along the fiber axis and the monofilament comprising the constituent yarn A having smaller shrinkage percentage has gradually changing thick parts and thin parts along the fiber axis. The composite yarn is obtained by supplying a plural number of yarns in the same or different speed to a feed roller, combining the yarn A and the yarn B by the twisting function of a false twisting rotor in the state having temperature difference after heat processing at least one yarn A by winding the thread around a rotating heater, and the yarn A is stretched while removing the feed roller and combining with the yarn B, and has yarn speed faster than that of the yarn B to manufacture the composite false twisted yarn.
