This one of a kind elastic residence on the spandex fibers is actually a direct results of the fabric’s chemical composition. The fibers are made up of diverse polymer strands. These strands are made up of two types of segments: lengthy, amorphous segments and short, rigid segments. Of their normal state, the amorphous segments Have got a random molecular framework. They intermingle and make the fibers gentle. A few of the rigid parts of your polymers bond with each other and give the fiber framework. Each time a force is placed on stretch the fibers, the bonds concerning the rigid sections are damaged, and also the amorphous segments straighten out.
