摘　　要：介绍了聚酯双驱动圆盘反应中熔体粘度波动大导致纺丝断头多的情况 ,设计了粘度控制程序方案 ,优化后提高了粘度控制水平 (波动由± 0 0 10降低到± 0 0 0 5 ) ,减少了直纺长丝断头率 ,降低了消耗 。The undulation of melt viscosity in double drive disk reactor and the yarn breakage in PET direct-spun filament process have been discussed. After design and optimization of the control program,the undulation of melt viscosity has been decreased (from ±0.010 to ±0.005) and the yarn breakage and consumption have been reduced and the quality of product has been improved.
