Effect of tensile fatigue cyclic loads on bagging deformation of elastic woven fabrics

Abstract

The bagging characteristics of elastic woven fabrics under tensile fatigue cyclic loads have been studied. The effect of draw ratio of core part and twist factor of cotton/spandex core-spun yarns on bagging characteristics has been studied. The results show that the amount of bagging fatigue of woven samples seems to be reduced when high level of draw ratio and low level of twist coefficient are applied. Furthermore, bagging fatigue increases after 1000 cyclic loads but no significant change is observed after 2000 cyclic loads
