POLYESTER COMPOSITE YARN EXCELLENT IN WARMTH AND STRETCHING ABILITY AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a manufacturing method of polyester composite yarn having excellent warmth and stretching ability, which comprises the following: a yarn supplying step of supplying polyester hollow yarn as an effect yarn and high shrinkage polyester yarn as core yarn; a contact heat treatment step of stretching and heat-treating the effect yarn through a heat roller; a non-contact heat treatment step of heat-treating the effect yarn heat-treated in the contact heat treatment step in a heat plate; an interlacing step in which the heat-treated effect yarn and the core yarn are laced through air entanglement; and a winding step of winding the interlaced composite yarn.;COPYRIGHT KIPO 2018
