喷气纺纱包缠捻度机理的探讨

The Forming Mechanism of Wrapping Twist in Air - jet Spinning

分析喷气纺纱的成纱结构,纱芯外包缠纤维捻度的形成机理。认为纱芯外层确有一定的真捻,且纱的毛羽方向具有一致性。其形成机理为假捻退捻包缠与捻差形成真捻两者的结合。

The paper analyses the structure of air - jet spinning yarn and the forming mechanism of wrapping twist on outer - shell of yarn. A mathematical model has been established to make certain the twist difference between the core and outer - shell of the yarn. It can be actually found that there are real twists in yarn core, and also consistent yarn hairiness direction. The forming mechanism of air -jet yarn twist is considered as the combination of wrapping twist on outer - shell and real twist in yarn core.
