摘要
为实现环保无锑熔体直纺半消光涤纶的稳定生产,可选用钛系催化剂(TY)。对此,文章采用改进三釜聚酯装置,通过分析聚合及纺丝工艺参数以制备94dtex/72f涤纶POY,研究钛系催化剂在涤纶熔体直纺半消光涤纶POY生产中的应用工艺,以期为其在熔体直纺中稳定生产提供参考依据。
In order to realize the stable production of environment-friendly non-antimony melt direct spinning semi-matting polyester,the titanium catalyst(TY)is selected.In this paper,the improved three-kettle polyester device is adopted,and 94 dtex/72 f polyester POY is prepared by analyzing the polymerization and spinning process parameters.The application of titanium catalyst in POY production of polyester melt direct spinning is also studied.It is expected to provide reference for stable production in melt direct spinning.
