摘　　要：为了探究不同结构对纱线条干、捻度、毛羽、芯吸、拉伸以及抗弯性能的影响,以涤纶和粘胶纤维为原料分别纺制了混纺纱、短纤维/短纤维包芯纱与长丝/短纤维包芯纱3种纤维含量比例相同、结构不同的纱线,对不同纱线进行结构与相关性能测试结果。比较分析发现,混纺纱中的涤纶短纤维随机分布在粘胶纤维中;涤粘短纤维/短纤维包芯纱包覆效果良好且芯层涤纶短纤会向皮层粘胶纤维中发生一定程度的转移;涤粘长丝/短纤维包芯纱中涤纶长丝抱合紧密且有“露丝”现象;涤粘短纤维/短纤维包芯纱条干CV值最大,捻度变异系数和不匀率最小;涤粘混纺纱的毛羽数量最多,芯吸高度最大;涤粘长丝/短纤维包芯纱的断裂强度和断裂伸长率最大,而涤粘混纺纱的抗弯力最大。In order to explore the effect of different structure on evenness,twist,hairiness,wicking height,tensile property and bending property,three kinds of yarns with the same fiber content ratio and different structure were spun with the polyester fiber and the viscose fiber respectively,which were blended yarn,staple fiber/staple fiber core-spun yarn and filament/staple fiber core-spun yarn.Their structure and relative performance were tested and compared.It is found that the polyester staple fibers are randomly distributed in the viscose fibers in the blended yarn.The coating effect of polyester staple fiber/viscose staple fiber core-spun yarn is good,and the polyester staple fiber in the core layer is transferred to the viscose fiber in the cortex to a certain extent,while the polyester filament in polyester filament/viscose staple fiber core-spun yarn is tightly held and has the phenomenon of"filament exposure".The unevenness of polyester staple fiber/viscose staple fiber core-spun yarn is the largest,while the coefficient of twist variation and twist irregularity are the smallest.The polyester/viscose blended yarn has the largest amount of hairiness,while the wicking height is the largest.Polyester filament/viscose staple fiber core-spun yarn has the largest breaking strength and elongation at break,while polyester-viscose blended yarn has the largest bending strength.
