Finite-element and multivariate analyses of tension distribution and spinning parameter effects on a ring-spinning balloon

Abstract

This study aims to investigate the effects of spinning parameters on the balloon tension and configuration. A novel experimental set-up was designed to measure the yarn tension at the pigtail. Experimental results were then used to implement boundary conditions in a multivariate analysis. Also, a finite-element (FE) code was used to predict the yarn balloon profile and stresses induced in the yarn. In particular, Coriolis acceleration and twist effects are considered on the model. It was observed that the equations governing the yarn path and the movement equation of twist in the yarn were completely dependent on each other. FE analysis revealed that while the Coriolis acceleration increases the tension in the yarn, it has little influence on the balloon configuration. Results of this study can be used to obtain optimized production parameters to increase the yarn quality and productivity.
