涤纶短纤维降粘生产及纺丝工艺

Study of spinning process in decreasing of polymer viscosity

探讨了降低聚合过程的熔体粘度对熔体可纺性的影响,并对如何通过优化纺丝工艺弥补降粘后对生产造成的负面影响进行了实践和研究。

As the increasing of PET capacity, the polymer viscosity would depress, the influence on polymer charc-teristics for spinning under this condition are discussed. The measures of process optimization are also described in this article.
