提高和稳定牵伸力的技术探讨

Technology Discussion on Improving and Stabilizing of Drawing Force

探讨提高和稳定牵伸力的技术措施。阐述了提高牵伸力的途径和遏制牵伸力波动的方法。论证了牵伸力与条干水平的关系,以及牵伸力提升快于移距偏差增加对重定量牵伸工艺的意义。认为:遵守牵伸原理,选择适宜的方法提高牵伸力均值,减少牵伸力波动,能够提高纺纱质量和效益。

Technology measures to improve drawing force and stabilize gripping force were discussed.The ways to improve drafting force and the methods to reduce the fluctuation of drafting force were described.Relationship between drafting force and eveness was demonstrated.Meaning of drafting force increasing is faster than shifting deviation increasing to heavy-quantity drafting process was demonstrated.It is considered that principle of drafting should be obeyed,appropriate method should be selected to increase the mean value of drafting force,fluctuation of drafting force should be reduced,then quality and efficiency of spinning can be improved.
