摘要

摘要气动槽式横向紧密纺丝是在气流和机械力共同作用下将纤维聚集在一起的纺丝工艺。与环锭纺纱相比,能更有效地减少纱线毛羽,提高纱线强度。然而,纤维在团聚区的运动是复杂的。为了准确地描述纤维的运动,建立新的纤维模型是十分重要的。本研究的目的是建立一种新的纤维模型来模拟团聚过程,分析气动槽侧紧纺纱的成纱性能,并通过一系列试验与其他纺纱进行比较。基于MATLAB实现的有限元方法,建立了新的纤维模型,以反映纤维在团聚区的运动情况。仿真结果与纺丝过程中纤维的实际运动情况较为接近。在气动槽侧紧纺纱中,纤维束通过团聚区进行聚集,纤维束在捻纱前的产量接近圆筒。实验表明,气动槽侧紧纺纱可以提高纱线的捻度,提高纱线的强度,减少纱线的毛羽。

Numerical Simulation of Fiber Motion in the Condensing Zone of Lateral Compact Spinning with Pneumatic Groove
Abstract Lateral compact spinning with pneumatic groove is a spinning process to gather fibers by common actions of airflow and mechanical forces. Compared with ring spinning, it can more effectively reduce yarn hairiness and enhance yarn strength. However, fiber motion in the agglomeration area is complex. And, it is important to establish a new fiber model to accurately describing the fiber motion. The objectives of this research were to create a new fiber model to simulate the agglomeration process, to analyze yarn properties of the lateral compact spinning with pneumatic groove, and to compare with other spinning yarns through a series of tests. The new fiber model was based on the finite element method implemented in MATLAB and was to show the fiber motion during the agglomeration area. The simulation generated results were close to the real motion of fibers in spinning. In the lateral compact spinning with pneumatic groove, fiber bundle through the agglomeration area can be gathered, and the output of the fiber bundle was nearly to cylinder before yarn twisted. The experiments demonstrated that the lateral compact spinning with pneumatic groove can improve the yarn properties: increase the yarn twist, enhance the yarn strength, and reduce the yarn hairiness.
