Abstract

PURPOSE:To efficiently obtain the subject twisted yarn having shape stability at a low cost by successively making two or more synthetic fiber yarns subjected to first twist collide with specifically arranged collision members, running, twisting and turning the yarns and then fusing the resultant contact parts of the yarns with heat generated in collision. CONSTITUTION:At least two synthetic fiber yarns 11 (e.g. nylon filament yarns) subjected to first twist are run, twisted and turned while being successively made to collide with many annularly arranged collision members 9, attached to a balloon controlling ring 7 and annularly arranged on the periphery of a winding bobbin 2. The contact parts of both the twisted and turned synthetic fiber yarns 11 are then fused with heat generated in collision of both the synthetic fiber yarns 11 with the collision members 9 to afford the objective fiber (Y).
