Since spandex possesses high breaking elongation (above 400%), high extensibility (500%-700%), low elasticity modulus (200% elongation 0.04-0.12 g/d) and high elastic recovery rate (200% elongation 95%-99%), therefore spandex material usually is mixed with a small amount of spandex to increase its retractility, recovery capacity and retention capacity, and hence fabric can be upright, extend and retract, and recover its shape quickly.
