为了克服静态接触表面环锭纺纱的细纱不匀恶化和毛羽减少不足的问题，本研究提出了一种改进的方法，通过使纺纱条与静态杆和自调节盘表面接触来改善细纱性能。从理论上分析了细纱性能改善的机理。分析结果表明，静杆与自调节盘面的结合可以提高纱线毛羽包缠力，且不会出现严重的捻纱堵塞，从而使纱线毛羽大幅减少，表面结构紧密，且不规劣化。相应地，纱线的强力也应有所提高。然后，通过无接触面旋转、静杆面旋转、静杆与自调盘面组合旋转等对比实验验证了我们的理论分析和预测。实验结果与我们的理论分析和预测非常吻合。
To overcome the spun yarn unevenness deterioration and insufficient hairiness reduction for ring spinning with a static contact surface, this study introduced a modified method to improve spun yarn properties by contacting the spinning strand with the static rod and self-adjustable disk surfaces. The mechanism of the improvement of spun yarn properties was theoretically analyzed. Analysis results indicated that the combination of the static rod and self-adjustable disk surfaces could improve the yarn hairiness wrapping force without sever twisting blockage, resulting in a large yarn hairiness reduction and surface tight structure without irregularity deterioration. Correspondingly, the yarn tenacity should also become somewhat enhancement. Then, our theoretical analysis and prediction were validated by conducting such comparative experiments as spinning without a contact surface, spinning with a static rod surface, and spinning with a combination of the static rod and self-adjustable disk surfaces. The experimental results were in good agreement with our theoretical analysis and prediction.
