For the optimum spinning condition, we study the effect of draw ratio and feed-in position on the structure and elasticity of elastic core-spun yarn. In addition, we examine the yarn cross section and elastic recovery in order to improve the yarn property. The results reveal that a feed-in position of 1200 has a better cover effect, and the draw ratio of 3~4 maintains a better and steady streach recovery. In addition, a draw ratio of 3.5 displays the better dynamic elastic recovery.
