Abstract:

In this experimental study, we investigated the effects of nozzle pressure, delivery speed and elastane content on the mechanical properties of core-spun yarns produced using the Murata vortex spinning system. Our findings show that the nozzle pressure, delivery speed, elastane content as expressed by the linear density of elastane yarn and the interactions of these factors are all significant factors affecting the mechanical properties of core-spun vortex yarns. Core-spun vortex yarns containing elastane show higher elongation at break and lower tenacity values than vortex yarns which contain no elastane. Increases in the nozzle pressure and decreases in the delivery speed resulted in significantly deteriorated mechanical properties of core-spun vortex yarns containing elastane.
