摘要
分析熔体输送条件对直纺FDY断头的影响 ,找出熔体输送的最佳工艺条件 ,认为缩聚负荷控制在 15 0~ 2 0 0t/d ,熔体流量保持在 1 45t/h以上 ,熔体温度在 2 86℃左右 ,保温道生温度在 2 80~ 3 0 0℃ ,输送压力在 2 1MPa时 。
To analyze the influence of melt transferring condition on direct spinning FDY full package ratio.Try to find out the best process condition of melt transferring.It is regarded that polycondensation load are controlled at 150~\{200 t/d\},melt flow is kept above 1.45 t/h,temperature of melt is 286 ℃,temperature of Dowtherm is controlled at 280~300 ℃,and transferring press is 21 MPa.The result shows that suitable polymer transferring condition can increase FDY full package ratio.
