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.
Highlights
The spinning industry is gradually developing to increase production, improve quality and reduce costs
They said the tenacity behavior of the vortex spun yarns can be attributed to two opposing effects: a) As the yarn becomes coarser, wrapping length of the wrapper fibers declines and this results in a decrease in tenacity and b) As the yarn becomes coarser, more will be the core fiber that will contribute to yarn tension, in other words, breaking load increases [17]
In vortex yarn due to the presence of wrapper fibers the cohesive force is greater than frictional force, so there is less chance of formation of pills on fabric surface as compared to ring spun yarn [23]
Summary
The spinning industry is gradually developing to increase production, improve quality and reduce costs. Hosne Ara Begum et al.: An Overview on Spinning Mechanism, Yarn Structure and Advantageous Characteristics of Vortex Spun Yarn and Fabric the produced yarn [4]. The VORTEX III 870 boasts the world’s fastest spinning of staple yarns at 500m/min This provides 20 times the production of ring spinning. Globalization has significant effects on the textile industry, including yarn production This means that a yarn producer must be technologically aware, efficient, flexible and cost conscious. Comprehending the modern technology will certainly affect the future setup of spinning industry in Bangladesh. From this perspective, it is attempted to make an overview of historical background, spinning mechanism, technical parameters, yarn structure and properties of vortex spun yarn. Properties of fabrics made of vortex yarn and advantages in post spinning process have been discussed
