Abstract (en)
[origin: WO2006081844A1] The invention relates to a method and a device for producing a crimped composite thread, wherein the inventive method consists in extruding, cooling and in drawing several yarns in the form of a plurality of strand filaments and in jointly crimping them in order to obtain a crimped composite thread. The aim of said invention is to make it possible to pre-treat the threads in a manner adaptable to each treatment step. The aim is attained by that at least one multi-treaded yarn is swirled many times during several operations prior to crimping. Foe this purpose, a swirling device provided with a plurality of swirling units following each other in a direction of the yarn displacement is used.
