摘　　要：与短纤维纱线不同,变形纱的质量条干均匀度和外观条干均匀度是2个相对独立的指标。EIB检测结果表明,空气变形纱的表观条干CV值接近于短纤维纱条干CV值,异收缩空气变形纱的表观条干CV值与短纤维纱条干CV值持平;空气变形纱表观直径变化总频数高于短纤维纱;空气变形纱表观直径变化频数集中分布于-25%－25%较短片段区域,异收缩空气变形纱的表观直径变化频数分布集中于-25%－50%的较长片段区域,这与短纤维纱的情况相同,显示了良好的仿短纤维纱效果。Uster 条干均匀度仪测试结果表明,空气变形纱和异收缩空气变形纱的质量条干均匀度CV值明显低于短纤维纱条干CV值,这对保持纱线的力学性能有利。Different to that of short-fiber yarn, textured yarn＇s mass evenness has nothing to do with its appearance evenness. According to the results of EIB test, there are not obvious difference between the air-jet textured yarn and the short-fiber yarn in the case of CV, while the differential shrinkage filaments air-jet textured yarn share the same CV with the short-fiber yarn; The air-jet textured yarn＇s appearance diameter changes more than that of short-fiber yarn; For the air-textured yarn, the frequency of appearance diameter diversification mainly stay in - 25 % - 25 % short segment area. For the differential shrinkage filaments air-jet textured yarn, it＇s in - 25% - 50% longer segment area, this is also the same as short-fiber yarn. According to Uster test, both air-jet textured yarn and differential shrinkage filaments air-jet textured yarn have a lower CV than the short-fiber yarn, this is beneficial to maintaining their mechanical properties.
