The tensile properties of spun yarns are accepted as one of the most important parameters for the assessment of yarn quality. Tensile properties contribute to the performance of post spinning operations; warping, weaving and knitting, hence their accurate technical evaluation carries much importance in industrial applications. This article presents a novel approach of classification of tensile properties into static and dynamic, based on the disposition of yarns during tensile testing. The definition of dynamic tensile properties and instruments utilized for their assessment are briefly discussed. Several theoretical and experimental work pursued on the static and dynamic tensile properties of ring, rotor, air-jet and friction spun staple yarns are critically reviewed. The article also throws light on the significance of exploitation of spun yarn dynamic tensile properties in industrial applications. The various material, spinning and testing parameters that influence static and dynamic tensile properties are summarized. The reported empirical equivalence of static and dynamic yarn strength of spun yarns is revealed. Current research work in the thrust area of spun yarns that are subjected to dynamic conditions is introduced.
