摘　　要：为更好地提高棉纤维的成纱性能,利用自主研发的假捻装置,在加装假捻装置的环锭细纱机上分别控制装置的速度、位置和纺纱方式,纺制了28.1 tex棉纱,并对成纱质量进行了测试分析。测试结果表明:假捻器在纺纱过程中的最优转速为300 r/min,速度过大或过小都会影响纱线的强力和毛羽;假捻点与前罗拉钳口的连线和水平线之间夹角的正切值为0.7时成纱效果最佳,假捻器的位置可改变纱路进而影响加捻三角区的大小和状态,纺纱过程中优选假捻器的合适位置有利于提高成纱质量;假捻器与斜位纺结合使用,改善了单一假捻纺纱情况下的纱线性能。In order to improve the spinning performance of cotton fiber,28. 1 tex yarn was spun by controlling the speed,position and spinning mode of the device on the ring spinning machine equipped with false twisting device. The quality of the yarn was tested and analyzed. The experimental result shows that the optimal speed of the false twister is 300 r/min during spinning. The strength and hairiness of the yarn will be affected if the speed is too large or too small. When the tangent between the false twisting point and front roller nip connection and horizontal line is 0. 7,yarn with the optimal quality can be spun. False twister position can change the yarn path,thus affecting the size and state of the twisting triangle. Preferred position of the false twister during spinning is beneficial to improve yarn quality. The combination of false twister and oblique spinning improves the yarn performance under the condition of single false twist spinning.
