Elastane material ,including natural rubber, synthetic rubber and elastane fiber is used far and wide in Non-woven Industry To compare with Spandex traditional natural/synthetic rubber have more difference between tensile stress and resiliency.
What is Spandex?
Spandex can be elongated 4-7 times and hark back after disengagement.
Spandex is suggested be elongated 3-4 times The most significant elongation can be 5 times.
Characteristic of Spandex :
Every yarn is made of several spun yarns which is uniform tension
About 3Kgs per roll
Recilient force of everu Dtex(g/10000m) us 3 times than elastics (0.024 force gram/unit)
Tge Stess and strain curves is more smooth Keeping smooth resiliency force in the dffective area (20%-30% elongation)
