Process monitoring and online control of each process in textile industry has received significant attention nowadays. Yarn tension in ring spinning is an important and critical factor and there are a few methods for real time measurement. In ring spinning system the spindle rotates at a constant angular velocity and the traveler is dragged around the ring by the yarn balloon. Understanding that how operating variables determine balloon dynamic stability and yarn tension cause by balloon is necessary to obtain machine efficient parameters. For the last fifteen years, the quite revolution of micro-technology and nanotechnology has taken place and is promising a bright future for most industries including textiles. Sensors are a type of microelectromechanical system and in this study a strain sensor is used to investigate some machine operating variables quantitatively. An experimental set up is devised to capture the signal through the interface by using data acquisition operating system (DAOS). After calibrating the system, various experiments are carried out on the ring spinning frame to assess the effect of the traveler weight, balloon height and displacement of pigtail on the compressive forces experienced by the yarn through rotation inside the balloon control ring. The results of this study show that the developed technique is a powerful tool for monitoring the variation in the compressive forces that yarn experiences during the contact with balloon control ring. It has been shown that increasing the weight of the traveler could result in decreased compressive forces. Also, it has been shown that decrease in balloon height will decrease compressive forces and an increase in pigtail displacement will increase compressive forces in the direction of displacement and will decrease it in the opposite side. Analysis of variance, Bonferroni and linear regression methods were used to evaluate the results.
