【摘要】 本文采用二次通用旋转组合设计建立了纱线强力、断裂伸长、毛羽、条干等纱线质量指标同粗纱喂入网距、纱线捻度、钢丝圈重量等细纱工艺参数之间的数学模型，再采用多目标函数优化法找到最优工艺参数组合。更多还原

【Abstract】 A mathematical relationship is set up by means of the scqare sphere design method between the yarn indexessuch as strength, broken elongation, hairiness, and evenness, and the spinning technological parameters such as roving feed gauge, yarn twist and traveller weight. Finally, an optimum technological parameters combination is obtained by analysis of multi-target function optimization.更多还原
