摘　　要：探讨多组分弹力包芯纱纺纱工艺的优化。对DOWXLA弹力丝的特性及与竹、竹炭、棉纤维混纺包芯纱的性能进行了分析,并针对多组分包芯纱生产中的难点,对细纱机进行了改造,并对各工序工艺参数进行了优选。通过采取一系列技术措施有效地控制了包覆不良、空心纱和裸丝等○点的形成,使所纺制的精梳棉/竹浆纤维/竹炭纤维18.2 tex(44 dtex)DOWXLA包芯纱达到了使用要求。Processing optimization of multicomponent elastic core-spun yarn was discussed. Properties of DOWXLA elastic filament bamboo, bamboo charcoal, cotton blended core-spun yarn were analysed. Spinning frame was modified aiming at the difficulties in producing multicomponent core-spun yarn and each process parameter were optimized. Through a series of technological measures defects including worse covering, hollow yarn and naked filament were controlled efficiently and finally quality of combed cotton bamboo charcoal fibre 18.2 tex （44 dtex） DOWXLA core-spun yarn could reach demands.
