Elastic recovery properties of polyester-cotton blended Eli-Twist yarns

Abstract

The influence of blend ratio, as well as amplitude and rate of extension on recovery properties of polyester-cotton blended Eli-Twist yarns have been studied. The composition of the yarn and the testing parameters are found to play important role in deciding the recovery characteristics of the yarn. A higher rate of extension is found to result in more immediate recovery, while a low rate of extension results in higher permanent deformation and low immediate recovery. On the contrary, the increase in amplitude of extension results in low immediate recovery and higher permanent deformation. Increase in the percentage of polyester assists higher recovery and low permanent deformation.
