This would make the amorphous segments for a longer period, thus expanding the duration of your fiber. In the event the fiber is stretched to its maximum duration, the rigid segments again bond with one another. The amorphous segments keep on being in an elongated state. This tends to make the fiber stiffer and stronger. Following the power is eliminated, the amorphous segments recoil and also the fiber returns to its relaxed state. By utilizing the elastic Qualities of spandex fibers, experts can build fabrics which have appealing stretching and energy features.

The main spandex fibers have been manufactured on an experimental stage by among the early pioneers in polymer chemistry, Farben fabriken Bayer. He acquired a German patent for his synthesis in 1952.
