Stick–slip behavior of para-aramid (Twaron®) fabric in yarn pull-out

Abstract

The aim of this study was to understand the stick–slip properties of para-aramid woven fabrics. Para-aramid Twaron CT®716 (CT716) and Twaron CT®714 (CT714) woven fabrics were used to conduct the pull-out tests. CT716 and CT714 woven fabrics have low and high fabric densities, respectively. Data generated from the single and multiple yarn pull-out tests using various lengths of CT716 and CT714 woven fabrics included fabric stick–slip force and accumulative retraction force. Stick–slip force and accumulative retraction force depend on fabric density and the number of pulled ends in the fabric. Stick–slip force and accumulative retraction force in the multiple-yarn pull-out test were higher than those of the single-yarn pull-out test. Stick–slip force and accumulative retraction force in single- and multiple-yarn pull-out tests in the dense CT716 fabric were higher than those of the loose CT714 fabric. In addition, long fabric samples showed high stick–slip force compared with that of the short fabric samples.
