摘　　要：影响工业丝条干均匀性的因素很多。传统纺丝设备在生产工业丝时,侧吹风甬道较宽,受到后加热器热辐射和丝束本身热量的影响,垂直滤网出来的侧吹风使从组件出来的丝束冷却不匀,容易造成条干不匀。经实践改造,通过在垂直滤网前方加装冷却整流框,可使侧吹风速均匀分布,可有效克服热辐射造成的条干不匀,使工业丝条干质量有较大改善。Evenness of PET industrial filament tow can be affected by many factors. When produced by regular spinning machine, the cross flow air from vertical filter can not quench the filament tow uniformly, thus the evenness of the filament tow is affected negatively. Based on practice, this article introduced a way to improve this situation. By adding a rectifier box in front of vertical filter, the distribution and speed of cross-flow cooling air will be more uniform, thus the evenness of PET industrial filament tow can be improved.
