利用充填干燥设备干燥PET瓶片生产涤纶短纤

PRODUCING THE POLYESTER STAPLE FIBER WITH THE DRYING RECOVERY PET CHIP THROUGH FILLING DRY MACHINE

重点介绍了充填式干燥设备干燥回收PET瓶片的情况,探讨了回收PET瓶片干燥效果、纺丝温度、冷却成形、牵伸和定型条件对生产三维卷曲中空涤纶短纤的影响。

The paper especially introduces the recovery PET chip through filling dry machine.It also studies the factors such as the drying effect of the recovery PET chip,spinning temperature,cooling,drawing and set condition which influence the production of spirl curve & hollow polyester staple fiber.
