摘　　要：由于条干均匀度是评价纱线外观特性的重要指标,与短纤维纱不同,变形纱线的表观条干均匀度和质量条干均匀度不相关。为最终达到空气变形纱线及其多重变形纱线结构和性能设计的目标,对长丝原料及几个关键变形工艺参数进行了初步的单因子实验。结果显示,异收缩空气变形纱的条干均匀度可以通过选择单、复丝线密度,空气变形加工和异收缩变形加工工艺参数的方法加以有效控制。空气变形加工工艺参数中的超喂率和喂入方式,异收缩变形加工工艺参数中的异收缩率、平均收缩率对成纱的条干CV值有显著影响。Evenness is an important factor in yarn appearance evaluation, different from the spun yam, the mass evenness of textured yarn has nothing to do with its appearance evenness. A series of unifactor experiments concerning several parameters of filaments and texturing were designed as the first step heading for the final designing and controlling of textured yarn＇s structure and properties. It has been proved that the evenness of the differential shrinkage filaments alr-jet textured yarn can be controlled effectually by the different filament or multi-filament linear density, air-jet texturing and differential shrinkage parameters. The over feed and feeding method in air-texturing, the differential shrinkage rate and average shrinkage in differential shrinking can affect the CV value of air-jet textured yarn remarkably.
