Natural lubrication mechanism of twisting in ring spinning and its experimental analysis

Abstract

Abstract In the spinning process, the natural lubricating film between the ring and the traveller changes the dry friction between them. In this paper, the composition of natural lubricating film is analyzed by DA1-180M microscope observation and Fourier infrared spectrometer. The eddy current sensor was used to detect the movement of the traveller on-line. The number of abnormal acceleration of the traveller reflects the stress stability of the traveller, and the lubrication effect of the natural lubrication film was analyzed. The experiment shows that the natural lubricating film is composed of the spun fiber, which can make the stress of the traveller relatively stable in the short term, but in the long term its lubricating effect cannot eliminate the wear between the ring and the traveller.
