熔体直纺单板细旦涤纶POY 350 dtex/384 f生产工艺

摘要

By melt direct spinning,the technology of producing fine denier POY 350 dtex/384 f polyester is introduced.The influence of process condition such as spinning pack,cooling condition,collection oiling,annealed zone,drawing condition etc on products quality were expounded.The results showed that the high quality production can be obtained by innovation of the quench air chamber and process parameters adjustment.%探讨了熔体直纺单板细旦涤纶POY 350 dtex/384 f生产工艺以及纺丝组件、冷却条件及集束上油、缓冷区、拉伸工艺等条件对产品质量的影响。结果表明,通过环吹风压的调整和优化工艺可以生产出优质产品。
