涤纶短纤维生产线前后纺生产能力的调整方法

介绍了涤纶短纤维生产线前后纺生产能力调整的方法 ,主要述及调整纺丝速度对原丝的影响 ,以及生产能力调整时应注意的几个问题。调整生产能力要根据产品纤度、现有喷丝板的情况来选择适当的纺丝速度 ,也可通过改变喷丝板孔数来实现。其他工艺条件也应做相应调整。实践证明 :调整前后成品的物理指标基本一致。

COMPREHENSION OF THE CAPACITY ADJUSTMENT ON POLYESTER STAPLE FIBER PRODUCTION LINE

The ways to adjust capacity of PET staple production line were introduced. The influence of spinning speed on as|spun fiber was described, as were the problems that should be noticed during the capacity adjustment. It was pointed out that the fiber denier and spinneret should be taken into consideration while selecting spinning velocity. And the capacity adjustment could be realized by the change of spinneret hole number. After 3|time adjustment, the capacity of fore|spinning and after|spinning reached balance. The production remained steady.
