摘　　要：为减少纺纱过程中纤维的损失,改善金属丝包芯纱质量,设计了一种设有负压抽吸锭子的新型低落纤喷气涡流纺纱喷嘴,对其各主要部件的制作工艺和降低落纤的原理进行了阐述。通过实验研究了抽吸孔轴向间距和抽吸孔周向列数对纤维损失和纱线断裂强度的影响。结果表明,在锭子内引纱通道壁面设置抽吸孔有利于减少纤维损失,提高纱线断裂强度。当轴向孔间距从2mm减小到1mm时,纤维损失和纱线强度均显著降低。当抽吸孔周向列数从2列增加为4列时,纤维损失和纱线断裂强度均显著降低,而当周向列数从3列增加至4列时,纱线断裂强度变化不明显。证实了在锭子内引纱通道壁面设置抽吸孔对实现低落纤喷气涡流纺纱和提高纱线质量的可行性,也为喷气涡流纺纱喷嘴装置的改进和发展提供一种新思路。In order to reduce the fiber loss in the spinning process and improve the quality of core-spun yarn containing a metal wire,a new vortex spinning nozzle for reducing fiber loss with air suction spindle was designed.The manufacturing process of its main components and the principle of reducing fiber loss are described.The effects of axial spacing of suction holes and number of columns of suction holes on the fiber loss and yarn breaking tenacity were studied experimentally.The results show that setting suction holes on the wall of the yarn passage through the spindle is conducive to reducing fiber loss and improving yarn breaking tenacity.When the spacing of suction holes is reduced from 2 mm to 1 mm,both fiber loss and yarn tenacity are significantly reduced.When the number of columns of suction holes is increased from 2 to 4,the fiber loss and yarn breaking tenacity are significantly reduced,while when the number of columns is increased from 3 to 4,the change of yarn breaking tenacity is not obvious.This study confirms the feasibility of setting suction holes on the wall of the yarn passage through the spindle to reduce fiber loss in vortex spinning and improve yarn quality,and it also provides a new idea for the improvement and development of vortex spinning nozzle.
