The textile industry has a great role in the improvement of any country's economy. Moreover, the ready-made garments need different coloured high yarn quality, so yarn should be rewinded on plastic cones for dyeing. However, manufacturers are facing the problem of tension variation during soft winding process that mainly affects the yarn quality. Consequently, to overcome the tension variation drawbacks, the attainment of constant optimal tension values is required in order to: (1) Increase the winding speed while maintaining the yarn quality, (2) Improve the dyeing quality, and (3) Reduce the water consumption during the dyeing process. In this paper, a proposed yarn tension control technique is introduced to upgrade the soft winding machine, thus maintain the yarn quality and improve the manufacturing capacity. The proposed technique has been tested on Polyester yarn samples classified as; fine, medium and coarse yarn counts, to cover most yarn sizes used in the industry. Arduino Mega 2560 controller is utilized to implement the proposed tension control. The results are compared to the conventional system to advocate the effectiveness and capability of the proposed technique in overcoming the trade-off between tension control and machine speed that occurs in conventional system using variable tension levels.
纺织业在任何国家的经济发展中都起着重要作用。此外,成衣需要不同颜色且纱线质量高,因此纱线应绕在塑料筒管上进行染色。然而,制造商在软卷绕过程中面临张力变化的问题,这主要影响纱线质量。因此,为了克服张力变化的缺点,需要获得恒定的最佳张力值,以便:(1)在保持纱线质量的同时提高卷绕速度;(2)提高染色质量;(3)减少染色过程中的用水量。本文介绍了一种提出的纱线张力控制技术,以升级软卷绕机,从而保持纱线质量并提高生产能力。所提出的技术已在分类为细、中、粗纱支的聚酯纱线样品上进行了测试,以涵盖该行业中使用的大多数纱线尺寸。利用Arduino Mega 2560控制器来实现所提出的张力控制。将结果与传统系统进行比较,以证明所提出的技术在克服传统系统中使用可变张力水平时出现的张力控制与机器速度之间的权衡方面的有效性和能力。
