Influence of Dorlastan® draft and yarn count on the elastic recovery of the Dorlastan® core spun yarns following cyclic test

Elastic recovery is one of the most important mechanical properties especially of clothing applications. This property is more and more significant when the textile structure contains elastane filament and has significant elasticity. In this study, we investigate the effect of the Dorlastan (R) draft and yarn count on the elastic recovery of cotton-covered Dorlastan (R) core spun yarns. These yarns are used as weft yarns in denim fabrics. Dorlastan (R) core spun yarns with different counts 100, 50, and 25 tex, with different elastane drawings and with the same twist factor are used. Our test results revealed that the Dorlastan (R) ratio and yarn count are important factors in influencing the elastic recovery.
