Spinning is one of the major steps in textiles to convert staple fibers from either natural or synthetic sources into continuous and twisted yarns. Since its invention, ring spinning has become the most widely used spinning technology due to the high yarn quality and applicability. However, the productivity is limited by its twisting and winding mechanism. Viable approaches to substantially improve the throughput of ring spinning are crucial. Therefore, this paper presents a systematic review of the literature on the state-of-the-art of disruptive technologies aiming at improving the throughput of ring spinning. Based on the governing equation of ring yarn productivity, two approaches of increasing spindle speed via reducing or eliminating ring-traveler friction and reducing yarn twist have been scrutinized. Increasing the spindle speed directly increases the centrifugal force and air drag of the yarn in the spinning balloon and exacerbates the traveler's wear. By reducing or eliminating the ring-traveler friction, it is possible to achieve a balance between improved productivity, similar energy consumption, and reasonable traveler wear. Since the yarn productivity is inversely proportional to the yarn twist, yarn productivity can be enhanced by reducing yarn twist with less energy consumption. However, with far less twist, the yarn strength is going to suffer. Therefore, both approaches improve ring yarn yield to some extent, and the level of improvement is subjected to the yarn count, fiber material, spinning conditions, etc. This review provides a clear view of the combination of both approaches to improve yarn productivity and energy efficiency. In the future, it is expected to see more studies of new alternatives which provide the ring spinning process with a cleaner and higher throughput compared to previous or current spinning technologies.

纺纱是纺织品将来自天然或合成来源的短纤维转化为连续和加捻纱线的主要步骤之一。自发明以来，环锭纺因其纱线质量和适用性高而成为应用最广泛的纺纱技术。然而，生产力受到其扭曲和缠绕机制的限制。显着提高环锭纺纱产量的可行方法至关重要。因此，本文对旨在提高环锭纺纱产量的颠覆性技术的最新文献进行了系统回顾。基于环锭纱生产率的控制方程，研究了通过减少或消除钢领与钢丝圈摩擦来提高锭速和降低纱线捻度的两种方法。提高锭子转速直接增加了纺纱球囊中纱线的离心力和空气阻力，加剧了钢丝圈的磨损。通过减少或消除钢领与钢丝圈之间的摩擦，可以在提高生产率、相似的能耗和合理的钢丝圈磨损之间取得平衡。由于纱线生产率与纱线捻度成反比，因此可以通过减少纱线捻度以较少的能量消耗来提高纱线生产率。然而，如果捻度要小得多，纱线强度就会受到影响。因此，这两种方法都在一定程度上提高了环锭纱产量，提高的程度取决于纱支、纤维材料、纺纱条件等。这篇综述清晰地展示了两种方法的结合，以提高纱线生产率和能源效率。未来，预计会有更多新替代品的研究，这些替代品为环锭纺纱工艺提供比以前或当前的纺纱技术更清洁和更高的产量。
