ANALYSING THE PHYSICAL AND MECHANICAL PROPERTIES OF CORE-SPUN YARNS
Journal Title: Annals of the University of Oradea. Fascicle of Textiles, Leatherwork - Year 2018, Vol 0, Issue 2
Abstract
Core spun yarn is also named as complex, compound, composite or hybrid yarn can be defined as the combination of filament and staple fibres. A filament which is called core is covered by staple fibres called sheath. In this study, it was aimed to analyse physical and mechanical properties of ring core-spun and ring dual core-spun yarns. Moreover, conventional ring and OE-rotor yarns were used as reference materials for better assessment. For this purpose, unevenness and imperfections, hairiness, frictional properties and tensile properties of yarns were measured. It was observed that core and dual-core spun yarns have better unevenness and imperfections values than conventional ring and OE-rotor spun yarns. Also, friction coefficients of core and dual-core yarns for all surfaces (yarn, metal and ceramic) were found lower than the equivelant 100% cotton conventional ring and OE-rotor spun yarns. Results showed that ring yarns have the highest hairiness values and it was also found that there is no statistically significant difference between hairiness values of core-spun and dual-core yarns. When the breaking force and breaking elongation were examined, it was seen that dual-core yarns have the highest values whereas OE-rotor yarns have the lowest.
