Abstract: Spinning systems based on mechanical twisting device have their limitations in terms of technical feasibility and economic viability. Making effort on yarn formation with the swirling air concept arouse of interest of the researchers for a long time. Air jet spinning had offered this opportunity for yarn manufacturers to produce yarn at relatively high production rate. Vortex spinning technology is a modified form of air-jet spinning which has attracted a lot of attention because of its advantages over ring spinning, open end and air-jet spinning in terms of production rate and yarn quality parameters. In this study, with stating some historical background, the mechanism of vortex spinning, structure and characteristics of vortex spun yarn have been overviewed. The body of vortex yarn is mainly constituted with twistless and parallel core fiber held together by helical surface wrapper fibers. All designated fiber types are found in vortex yarn such as wild fibers, belly band fibers, parallel and helical fibers. In case of quality consideration, air-vortex yarn has higher values of tenacity compared to the rotor yarn & air-jet yarn. This yarn has also improved characteristics compared to the ring and rotor yarns in terms of hairiness, evenness and bending rigidity. On the other hand, the advantageous properties of fabric produced from vortex yarn such as pilling resistance, delicate printing capability, comfort characteristics etc. have been discussed. Finally, advantages obtained in some post spinning processes such as sizing, better loom shedding, drying of fabric after dyeing etc have also been mentioned in this paper.Abstract: Spinning systems based on mechanical twisting device have their limitations in terms of technical feasibility and economic viability.
