摘　　要：纤维截面形状对聚酯(PET)长丝结构和性能的影响可通过在相同纺丝条件下选用不同形状喷丝头制备聚酯预取向丝进行研究。纤维之间的唯一区别是所采用喷丝头的横截面形状。试验选择了不同的截面形状,包括圆形、中空、三叶形、八叶形和三角形。特殊形状的喷丝头所制得的纤维被用于地毯或家用纺织品等不同用途,圆形截面纤维则被用于牛仔布的生产。纤维截面形状的差异主要受其模量、高应变、屈服应力和沸水收缩的影响,还未确定是否对纤维结晶度和高应力产生影响。结果发现:圆形截面的350/96聚酯预取向丝在各阶段均表现出较好的性能。The effect of fiber cross-sectional shape on the structure and properties of polyester(PET)yarns have been investigated by the selection of partially oriented polyester yarn(PET POY),which was produced under the same spinning conditions through different spinnerets in a melt spinning plant.The only difference between the fibers are the cross-sectional shapes of spinneret.The different cross-sectional shapes were selected for the experimental work including circular,hollow,trilobal,octalobal and delta.The yarn that produced by special spinnerets will be considered for different applications in carpets and home textiles,whereas circular cross-section yarn will be considered for denim fabric manufacturing.The major difference within the cross-sectional shapes are influenced due to their modulus,higher strain,yield stress and boiling water shrinkage.No effects on the crystallinity and higher stress were determined.It was found that 350/96 PET POY showed improved results with circular cross-section at all stages.
