摘　　要：本文对PET/PBT共聚酯纤维纺纱工艺进行了设计,研究了PET/PBT共聚酯纤维可纺性以及细纱和织物性能。通过研究得出,PET/PBT共聚酯纺纱工艺应采用低车速、高定量的原则。梳棉和粗纱条干均匀,细纱上浆后断裂伸长率下降。该研究拓展了共聚酯纤维的开发和应用新领域。The spinning process of PET/PBT copolyester fiber were designed in this paper.The spinnability of PET/PBT copolyester fiber and the properties of spun yarn and fabric were studied.Through research,it could be concluded that the PET/PBT copolyester spinning process should adopt the principles of low speed and high weight.The carded and roving slivers were evenly dried,and the fiber elongation decreased after the sizing of the spun yarn.It also extended the development and application of PET/PBT copolyester fibers.
