摘　　要：采用熔体直纺POY-DTY工艺路线生产167 dtex/96 f细旦DTY异型抗菌丝,探讨了其加工工艺条件。经过实践证明:加工速度YS在680 m/min左右,第1热箱温度H1控制在(185±2)℃以内,成品丝断纱少、毛丝少、DTY异形度好、变形效果佳。把167dtex/96 f的异形抗菌丝拉伸比DR控制在1.55,同时选择速比D/Y在1.6,生产的毛僵丝较少及成品丝的物理性质满足要求。同时调整第2热箱温度和网络压力为,降低残余扭矩,改善产品的集束性,提高了产品的退绕性,更好地提升了产品可加工性。The production process conditions of 167 dtex/96 f fine denier DTY shaped antibacterial yarn were explored using the melt direct spinning POY-DTY process route.It was proven through practical experience that with a processing speed of YS at around 680 m/min and the first hot box temperature H1 controlled within(185±2)℃,the finished yarn has less yarn breakage,less fluff,good DTY shaping and good deformation effect.The drawn ratio DR of the 167dtex/96 f shaped antibacterial yarn was controlled at 1.55,and the speed ratio D/Y was selected at 1.6.This resulted in less woolen dead silk during production and the physical properties of the finished yarn met the requirements.In order to reduce residual torque,improve product bundling and enhance product rewinding performance,the second hot box temperature was set at 150℃and the network pressure was set at 0.16 MPa.
