Present paper reports the effect of change of spandex denier on the properties of stretchable lyocell-spandex cover spun yarn. The core component was spandex with 20D and 40D while sheath consisted of lyocell yarn; eco-friendly regenerated cellulosic yarns. The stretchable cover spun yarns were produced in a hollow spindle spinning frame. ANOVA was applied to study the significant effect of presence of spandex as well as effect of variation in denier of spandex was also noted. It was observed
