LINEN POLYESTER COMPOSITE YARN HAVING EXCELLENT ELASTICITY AND REBOUND RESILIENCE AND PRODUCTION METHOD THEREOF

摘要

The present invention relates to a linen polyester composite yarn having excellent elasticity and rebound resilience, comprising: a yarn supply step of supplying partially oriented low-viscosity polyester as an effective yarn, and a latent-crimp yarn of a side-by-side type using high-viscosity polyester and a low-viscosity polyester as a core yarn; a contact heat treating step of orienting and heat-treating the effective yarn through two heat rollers; a non-contact heat-treating step of heat-treating the effective yarn heat-treated in the contact heat treating step, on a heat plate; a bridging step of braiding the heat-treated effective yarn and the core yarn through air braiding; and a winding step of winding the braided composite yarn. Further, the present invention relates to a production method thereof.;COPYRIGHT KIPO 2017
