高速涡流对环锭纺成纱质量的影响

Effect of High-speed Vortex on Ring Spinning Yarn Quality

为研究高速涡流对环锭纺成纱质量的影响,在环锭细纱机前钳口至导纱钩之间安装了自制的高速涡流装置;采用6种气流加压量对4种不同线密度纱进行纺纱试验,并对成纱质量进行了对比分析。结果表明在Z捻纺纱情况下,细纱有害毛羽减少量达到55.2%～60.8%;强力增加6.8%～10.8%,且随着气流加压量的增大,成纱强力先增加后降低;细纱实际捻度下降8.1%～10.7%,纱线细度越小实际捻度下降幅度越大;对细纱条干影响不大。

In order to discuss the effect of high-speed vortex on ring spinning yarn quality, The self-made high-speed vortex de- vices between the front roller with yarn guide in ring spinning flame were added. Spinning quality contrast tests were carried on 4 different linear densities of yarns using 6 kinds of flow pressure. The result proved that in condition of Z twist yarn, yarn harmful hairihess can reduced from 55.2% to 60. 8%. Yarn strength can increased from 6.8%to10. 8%. With the amount of air pressure increasing, yarn strength increased first and then decreased. The yarn actual twist reduced from 8. 1% to 10.7%. The yarn fineness became smaller as yarn actual twist declined. The yarn evenness has little effect using high-speed vortex method.
