摘　　要：超大牵伸纺纱技术具有工艺流程短、成本低、生产效率高、成纱质量好等优点。超大牵伸条件下对纤维牵伸力进行研究，有利于改善成纱质量、提高生产效率。利用TH558型超大牵伸细纱机，改变总牵伸倍数、中区牵伸倍数和罗拉加压进行纺纱试验。经分析发现：随着总牵伸倍数和中区牵伸倍数的增大，牵伸力变小，牵伸不匀率变大，牵伸变得不稳定，成纱质量变差。在牵伸力与握持力相适应的条件下，罗拉加压越大。成纱质量越好。Super high draft spinning technology has the advantages of shortened process flow, reduced cost, improved production efficiency and good quality of the yarn. It is helpful to improve the quality of yarn and improve the production efficiency by studying the drawing force under the condition of large draft. Spinning test is carried out with TH558 super high draft spinning machine by changing draw ratio, middle draft ratio and roller pressure. It is found that with the increase of the total draft ratio, the drafting ratio increases, the drawing force becomes smaller, the drafting unevenness becomes larger, the draft becomes unstable, and the yarn quality becomes poorer. In the adapted drawinz force and zriD force, the zreater the roller pressure is. the better the yarn zualitv is.
