In this experiment, we use a 44.4 dtex/4f spandex filament as the core and cotton fibers as the sheath to spin 19.7 tex elastic core-spun yarn. In order to improve yarn performance, we examine the yams cross-sectional structure and investigate the effect of draw ratio and feed-in angle of the spandex on the yarns' structure and performance. The results show that a higher feed-in angle provides a better cover effect and a draw ratio of 3.5 yields better dynamic elastic recovery.
