Study on the yarn compressive stresses at balloon control ring by signal processing

Process monitoring and online control of each process in textile industry has received significant attention nowadays. Yarn tension plays an important role in ring spinning and there are a few methods for real-time measurement of yarn tension. To obtain machine efficient parameters, it is necessary to understand how operating variables determine yarn tension and balloon dynamic stability. In this study, compressive stresses that are acting on the yarn by balloon control ring are investigated by manipulating of signal processing. An experimental set up is devised for capturing and monitoring the signals through of a data acquisition interface. The results show that decreasing the balloon height or increasing the traveler mass will lead to a decrease in compressive forces acting on yarn at balloon control ring. Analysis of variance, Bonferroni test and linear regression methods were used to evaluate the results. The results have been analyzed in the frequency area as well.
