摘　　要：结合聚对苯二甲酸丙二酯的特性及客户需求,就中空喷丝板、环吹风速、纺丝温度、纺丝速度等工艺参数对产品质量的影响进行了探索,通过重新设计中空喷丝板和优化工艺参数,开发出了客户需要的6.67 dtex三维卷曲聚对苯二甲酸丙二酯中空短纤维。Combining the characteristics of poly（trimethylene terephthalate） （FTT） and customer require- ments, the process parameters such as hollw spinneret, ring blowing wind speed, spinning temperature, spin- ning speed and etc influenced on the products quality were explored. Through the redesign of the hollow spinneret and optimization of process parameters, 6.67 dtex three-dimensional crimped PTT hollow staple fiber was developed.
