The Fantastic elasticity of spandex fibers raises the clothing's stress consolation, boosting the convenience of entire body movements. Force comfort and ease may be the response toward clothes from the human body's tension receptors (mechanoreceptors existing in skin sensory cells).
The simple condensation of diols and diisocyanates was regarded within the 1930s as the results of do the job by Otto Bayer.[six] Fibers ideal for changing nylon were not created from urethanes, but as an alternative this theme led to a loved ones of specialized elastic fabrics.
