The results show that the variation of diameter of ATF yarn increases with increasing the over feed of peel filament, but the variation of average diameter decreases. When the polyester FDY is used as core filament, the structure of diacetate composite ATF is looser than the ATF with capron as core filament, and the unevenness of yarn core and outside are also greater. The ATF loops or hairiness mainly centre at the height 0.5 and 1.0 mm, the amount decreasing with the height increasing, with exponential distribution. When the over feed of peel filament enhances, the number of loops or hairiness decreases at the height of 0.5 mm, while other height of loops or hairiness increases.

结果显示：空变丝纱芯直径的变异随皮丝超喂提高而增加，但平均直径的变异却呈下降趋势；以涤纶FDY做芯丝时，二醋酯长丝复合空变丝的结构较芯丝为锦纶的空变丝松散，纱芯和外围不匀程度也相对较大；空变丝丝圈丝弧或毛羽主要集中在高度为0.5mm和1.0mm的位置，其个数随高度的增加而不断减少，基本呈指数分布；皮丝超喂提高时，0.5mm高度的丝圈丝弧或毛羽个数减少，其他高度的丝圈丝弧或毛羽个数则增加。
