摘　　要：为探讨影响空心锭包覆纺纱包缠捻度及其分布的因素及影响程度,分析了外包缠纱退绕及芯纱在包缠张力作用下扭转产生的附加捻度,以及影响附加捻度大小和波动的因素;对采用不同芯纱速度、线密度、张力以及粗细不匀芯纱纺制的包覆纱进行了捻度测试与比较分析。结果表明:外包缠纱退绕产生的附加捻度的捻向与包缠捻向相同,而芯纱扭转产生的附加捻度的捻向与包缠捻向相反;随纺纱工艺的不同,二者的共同作用决定了包缠捻度的偏差大小和分布均匀度;包缠捻度具有纱线加捻的类似捻回分布特征,芯纱粗细不匀显著影响短片段捻回分布均匀度,粗节处捻回少,细节处捻回多。In order to explore the factors affecting the wrapping twist and twist distribution,the additional twists produced by the yarn unwinding of the outer wrapping yarn and the twist of the core yarn under the wrapping tension,as well as the size and fluctuation of the additional twist were analyzed.Twist test and comparative analysis of the covered yarn spun with different core yarn speed,linear density,tension and uneven thickness core yarn were carried out.The results show that the twist direction of the additional twists generated by the unwinding of the outer wrapping yarn is the same as the wrapping twist direction,while the twist direction of the additional twist generated by the twisting of the core yarn is opposite to the wrapping twist direction.Depending on the spinning process,the combined effect of the two types additional twists determines the deviation size and distribution uniformity of the wrapping twist.The wrapping twist has the similar twist distribution characteristics to the yarn twist,and the unevenness of core yarn significantly affects the evenness of short-term twist distribution,with less twisting at thick places and more twisting at thin places.
