This unique elastic assets on the spandex fibers can be 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: extended, amorphous segments and brief, rigid segments. Of their pure condition, the amorphous segments have a random molecular composition. They intermingle and make the fibers comfortable. A few of the rigid parts on the polymers bond with one another and give the fiber structure. Every time a power is placed on stretch the fibers, the bonds in between the rigid sections are damaged, as well as the amorphous segments straighten out.
