Review of distribution of fiber tension at the spinning triangle

In the ring spinning process, the spinning triangle plays an important role in the quality and efficiency of yarn spinning. The distribution of fiber tension at the spinning triangle is important. In this study, models such as energy methods, energy methods using false twist, and finite element method are applied. The model parameters on the distribution of fiber tension in the symmetric and asymmetric spinning triangle with a uniform distribution of single fiber, uniform distribution of fiber types, and distribution buckling fibers in the spinning triangle are analyzed. The results show that there is an increase in the distribution of fiber tension in symmetric spinning triangle. Fibers, depending on their position in the spinning triangle, have different tensions. In single fibers in the twist point, the tension of the fiber bundle is maximum, the fiber tension is less, and the compression force of the fiber bundle is greater. The spinning triangle shape is effective on the distribution of fiber tension.
