摘　　要：基于聚酯纤维的结构、性能、工艺的一般关系 ,对专利文献中的关键工艺和设备研究进展 ,从聚合物结构控制角度进行了综述。重点阐述了对原料的特性粘数、未拉伸纤维的均匀性 (包括条干均匀性、丝束中单根丝均匀性以及每一根丝的截面均匀性 )、未拉伸纤维和拉伸工艺中的取向结晶的控制方法和原理。The key progresses in processing and apparat us of polyester industrial yarn production were reviewed in the light of structu re controlling during the formation processes according to the relationships of s tructure-properties-processing.The controlling on intrinsic viscosity of raw m aterial,the irregularities of undrawn yarn, the orientation and crystalline s tructure of the undrawn and the yarn during the drawing process was illustrated in detail.The irregularity of yarn was characterized by three means at least,w hich include the mass variations of yarn,the filament diameter variations of the cross-section of yarn,and the orientation and crystallinity variations of each filament cross-section.
