Evaluation of physical properties of core spun yarn through variation of core numbers

Abstract

The core-spun yarn has gained much concern and popularity all over the world for having elastic and comfort properties. Draft ratio of the core, the number of cores and the type of sheath material are the prime parameters of producing core-spun yarn. These parameters influence the physical and mechanical properties of the yarn. In this study, the effect of the number of core-spun yarn cores was investigated on the yarn's physical and mechanical properties. Two types of core-spun yarn were produced: single core-spun yarn and dual core-spun yarn. Cotton fibres were used as a sheath, spandex monofilament and polyester multi-filament were used in the core. It was revealed that dual core-spun exhibits lower unevenness, imperfection and hairiness value than single core-spun yarn. In addition, bundle strength of yarn was found higher in dual core-spun yarn.
