This will make the amorphous segments longer, thereby growing the length of the fiber. When the fiber is stretched to its maximum length, the rigid segments again bond with one another. The amorphous segments remain within an elongated point out. This tends to make the fiber stiffer and more powerful. Following the pressure is eliminated, the amorphous segments recoil plus the fiber returns to its peaceful point out. By utilizing the elastic properties of spandex fibers, scientists can build fabrics which have fascinating stretching and power traits.

Subsequently, DuPont Fibers developed their model of spandex beneath the name Lycra. In some aspects of the whole world currently, the title Lycra is becoming the generic name for elastomeric spandex yarn.
