Predicting of Coil Length of Components Spirally Arranged in Complex Structure Yarns

Abstract

The present work proposes the theoretical methodology to predict the coil length of components spirally arranged in complex structure yarns. Such types of yarns as the covered yarns and the yarns with structural effects are analysed. The predicting methods are addressed to yarns produced in one process by means of hollow spindles technology. The predictive equations are proposed. As the initial data the technological parameters of manufacture process of complex structure yarn, also the structural parameters of the used components are necessary. The results of predicted coil length and the experimental values of coil length are presented. The comparison of the predicted coil length with available experimental data shows rather good agreement.
