Abstract

PURPOSE: To prevent the wrapping of filament yarn around draw rollers due to broken filaments and lowering of operating efficiency in drawing at high speed and draw ratio, by inter twining a synthetic filament yarn under tension with a high-speed fluid between the feeld rollers and draw rollers.
CONSTITUTION: The extruded flament yarn 1 is primarily drawn between the feed rollers 5 and the draw rollers 6 and 6', then secondarily drawn between the second draw rollers 9 and 9'. The broken filaments occurred in the drawing are intertwined in the yarn by the fluid intertwining device 8 to prevent the wrapping aroud the draw rollers. Preferably, the intertwining is carried out to give the hook drop length of 40W98 of the drawn filament yarm.
EFFECT: Drawing operating efficiency and product yield can be improved particularly in drawing of multifilament yarns of coarse denier without twist at a high draw ratio and high speed direct spinning and drawing
