The experiment and test results indicated that the various properties of elastic core-spun vortex yarns were significantly affected by spandex and yarn count. Coarser yarns showed lower unevenness, imperfection and breaking elongation values than finer yarns. Core-spun vortex yarns containing spandex showed lower tenacity and higher breaking elongation values than vortex spun yarns. The liveliness of spandex affected the hairiness properties of core-spun vortex yarns. The number of fibers in the cross section and the liveliness of spandex must be evaluated together during the manufacturing process of elastic core-spun vortex yarns.eninfo:eu-repo/semantics/closedAccessCore-spun yarnElasticityBreaking elongationCore-spun yarnYarnHairinessSpandexVortex yarnHairinessCore spinningCountCross sectionElongationVortex spinningYarn manufactureYarn propertySpinning (fibers)Spinning machinesPolyurethanesTenacitySpandexMVS spinningMVS yarnArticle0002510326000082-s2.0-36049044740432436776Materials science, textilesSiro; Ring-Spun Yarn; Ring Spinning
