Objective measurement of structural parameters of rotor-spun yarns

Abstract

An intensive study has been carried out to define the structure of rotor-spun yarns objectively and to find out the contribution of structural parameters to yarn properties. It is observed that the measured twist of rotor-spun yarn is correlated poorly with yarn tenacity, count strength product (CSP) and elongation-at-break. The structural parameters of the yarn are highly correlated with yarn tenacity, extension, CSP and hairiness. The addition of twist enhances the correlation in some cases.
