Abstract
The tensile properties of spun yarn are accepted as one of the most important parameters for assessment of yarn quality. The tensile properties decide the performance of post spinning operations; warping, weaving and knitting; hence its accurate technical evaluation carries much importance in industrial applications. An important aspect of dynamic tensile testing of spun yarns is the possibility of predicting the performance of yarn in subsequent processes. Continuous tensile testing of spun yarn involves transporting the yarn under constant tension at constant output speed. Thus, in continuous testing every inch or millimeter of yarn is tested to generate true elongation of yarn at specific dynamic tension & speed condition, and the tensile characteristics are continuously assessed. Dynamic tensile properties measured by continuous testing simulate actual manufacturing conditions more closely than the static tensile testing.
