PURPOSE:To manufacture a composite spun yarn having excellent feeling and appearance, stably for a long period, at a high speed, by combining a short fiber fleece with another yarn between a stretch-breaking roller and a fluid-drawing nozzle in the drawing of a short fiber fleece to a yarn, and passing the fleece together with the yarn through the fluid-drawing nozzle. CONSTITUTION:A drawn tow 1 of polyester filaments is subjected to the drawing and stretch-breaking between the feed roller 5 and a pair of stretch-breaking rollers 9 rotating at higher speed than the feed roller. The obtained short fiber fleece 6 delivered from the fluid takeup nozzle 10 is combined between the stretch-breaking roller 9 and the fluid drawing nozzle 11 with a polyester multifilament yarn 2 stretched under a tension of preferably 0.5-1.5g/d, and passed through the nozzle 11 to intertwine and wind the short fiber fleece around the filament yarn 2. The obtained composite spun yarn 12 is wound by the winder 14 in the form of a cheese 15. The distance between the roller 9 and the point to combine the short fiber fleece 6 with another yarn 2 is preferably <=1.2 times the average fiber length of said fleece 6. |
