Unlevel dyeing and fineness-unevenness of multifilament yarn;
复丝纱的染色不匀和线密度不匀
This article analyses the effect of determinating condition on POY’s spectrogram,unevenness curve and CV value by Uster yarn evenness meter Ⅲ,and the relation between spectrogram and the technological condition and the mechanical condition.
分析测试条件对ＵＳＴＥＲ－Ⅲ条干均匀度仪测定ＰＯＹ的波谱图、不匀曲线图及ＣＶ值的影响，以及仪谱图与工艺条件、设备状态的关
