摘　　要：苎麻纤维粗硬，弹性回复性差，成纱毛羽多，且残余扭矩大，织物表面纬斜严重。为改善纱线质量，降低细纱的残余扭矩，采用赛络低扭纺纱技术试纺了16．7tex纯苎麻细纱，探究了喇叭口位置、假捻器高度、假捻器与前罗拉的速比、钢丝圈规格对成纱质量的影响．并对细纱的断头率、断裂强力、毛羽指数、条干均匀度几个指标进行了测定和对比。得出纺16．7tex纯苎麻赛络低扭纱的最优工艺参数为喇叭口位置左移0．5cm、假捻器高度为1cm、假捻器与前罗拉的速比为2．5、钢丝圈规格为G2。Ramie fiber is coarse and hard with poor elastic recovery and long hairiness. Ramie fabric features serious weft deviation due to its large residual torque. In order to improve the yarn quality and reduce residual torque of the ramie yarn, 16.7 tex （about 60 Nm） pure ramie yarn is tested by using siro low torque spinning technology. The effects of the place of horn month, the height of the false twister, speed ratio of the false twister and the front roller, and the weight of traveler on the yarn quality are explored. The yarn breakage rate, breaking strength, hairiness index, yarn evenness are tested and comparatively analyzed. The result show that the best parameters of siro low-torque spinning of 16.7 tex pure ramie is a shift of horn mouth of 0.5 cm to the left, height of false twister of lcm, the ratio of the false twister and the front roller of 2.5 and traveler specification of G2.
