The percentage of set defines the organic elasticity of spandex fiber. Visualize a fiber AB elongated to position C by pulling, and it reaches level D. If the pull is introduced, we observe which the fiber doesn’t wholly return to position B, showing a recovery of lower than one hundred%. Therefore
