Through the production trial, analysis is done to the application of the domestic spinning draft parts of V shape, pneumatic pressurizing, cots with low rigidity and hi-elasticity, new top and bottom aprons and mid-rollers on the drafting system of the spinning frame in relation to quality of resultant yarn.
通过生产试验，分析了细纱机牵伸系统采用国产新型V型牵伸、气动加压、低硬度高弹性胶辊、新型上销、下销、中胶辊等纺纱器材和合理工艺配置对成纱质量的影响，并重点对V型牵伸后区倍数、罗拉隔距、气动摇架压力大小和前胶辊的前冲量进行研究，探讨了提高成纱质量的有效途径。
