Abstract:

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 rung 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 horzontal line is 0.7, yarn eith the optimal quality can be spun. False twister position can change the yaran 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 combinationof false twister and oblique spinning improves the yarn performance under the condition of single false twist spinning.

Key words: false twister, cotton yarn with low twist high strength, spinning twist triangle, oblique spinning, ring spinning machine
