Abstract
The present invention relates to: a polyester-based composite false-twisted yarn in which a PET / PTT latent crimped yarn is used as a core yarn, and a partially oriented yarn is loosely arranged on the exterior as an effect yarn by minimizing the draw ratio during the manufacture of the composite false-twisted yarn; and a method for manufacturing same. The polyester-based composite false-twisted yarn of the present invention has improved elasticity due to waves of the core yarn, compared to conventional composite false-twisted yarns, and can provide the effect of improving touch feel due to waves of the effect yarn.
