These strands are made up of two types of segments: very long, amorphous segments and small, rigid segments. Inside their pure condition, the amorphous segments have a random molecular composition. They intermingle and make the fibers tender. A lot of the rigid parts on the polymers bond with each other and give the fiber framework. Each time a power is placed on stretch the fibers, the bonds in between the rigid sections are damaged, plus the amorphous segments straighten out.
