【摘要】 作者通过对多种细纱机牵伸型式的分析和对各种牵伸型式配置适当的工艺参数的试验,证明不同的牵伸型式若能配以适当的工艺参数可取得较为良好的成纱质量;还用对比数据证明用进口牵伸部件改造的细纱机,配上适当的工艺参数也能达到整台进口的细纱机的纺纱水平。更多还原

【Abstract】 Through analysing a series of ring frame back zone drafting types and the corresponding technological parameters, it is proved that quality yarn can be manufactured with any drafting type with suitable technological parameter, and that the yarn spun by the ring frame fitted with imported drafting system is as good as that spun by an imported ring frame.更多还原
