摘　　要：为探讨空心锭包覆纺纱区别于其他采用空心锭机构纺纱技术的包缠作用特征,对包覆纺纱与平行纺纱、空心锭花式捻线技术的工艺路线和包缠作用原理进行比较,指出包覆纺纱采用“顺向包缠”的工艺配置实现外包缠纱对芯纱的直接包缠,并对包缠作用进行速度分析和张力分析。结果表明:外包缠纱包缠角的波动,在芯纱速度与包缠速度匹配失衡时,会引起包缠点的移动,会合导纱钩将缠绕点的波动及由此导致的包缠捻度变化限制在较小的范围内;一定的芯纱张力是实现正常包缠作用的必要保证,张力匹配不当导致的包缠点偏离中心线会引起包缠结构的变化;包缠张力使芯纱产生与缠绕方向的同向回转,对包缠捻度有抵消作用。In order to explore the wrapping effect characteristics of hollow spindle covered spinning which is different from other spinning technologies with hollow spindle mechanism,the process route and wrapping principle of covered spinning,parallel spinning,and hollow spindle fancy twisting technology were compared,the"forward wrapping"process was adopted for the direct wrapping of the core yarn by the outer wrapping yarn in covered spinning,and speed and tension analyses were carried out on the wrapping action.The results show that the wrapping angle of the outer wrapping yarn causes the wrapping point to move when the core yarn speed and the wrapping speed are unbalanced,and the joining guide wire imposes limits on the fluctuation of the wrapping point,resulting smaller range of wrapping twist variation.A suitable core yarn tension was found a necessary guarantee for achieving normal wrapping,and the deviation of the wrapping point from the center line caused by improper tension matching would cause change in wrapping structure.The wrapping tension causes the core yarn to rotate in the same direction as the wrapping direction,which has a counteracting effect on the wrapping twist.
