    Abstract: PROBLEM TO BE SOLVED: To obtain a false twist yarn capable of achieving a feeling of simultaneously representing a firm feeling, a dry feeling and softness of surface touch which a conventional woven fabric or knitted fabric cannot achieve. SOLUTION: In false twisting two or more thermoplastic thick and thin multifilament yarns, each yarn is fused in a twisted state in the same direction in a heater, then the yarns are joined by twisting action of the false twisting to give a false twist yarn of a specific structure in which bundled parts of plural fused and bundled filaments and non-bundled parts exist in a combined state and the bundled parts and the non-bundled parts alternately form longer length parts.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for stably producing a bulky yarn capable of exhibiting fullness rich in a natural feeling and a touch feeling without a core when the yarn is formed into a woven or a knitted fabric by imparting a difference in filament length or/and a difference in shrinkage among constituent filaments and further changing the shrinkage percentage in the fiber axial direction. SOLUTION: Feed rollers, a turning nozzle, a hot roller and takeoff rollers are installed in the order mentioned in the yarn running direction and a feed multifilamant yarn in a state thereof false twisted with the turning nozzle is brought into contact with the surface of the hot roller rotating at the substantially same speed as that of the feed rollers in a short time so as to produce unevenness of heating among the constituent filament. Thereby, the difference in filament length or the difference in shrinkage or both are imparted among the constituent filaments.

    Abstract: 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.
