The meaning of spandexSpandex is a Polyether based Elastane fiber having excellent
resistance to acid and alkaline wet processing conditions, high
modulus and high tensile strength, resistance to discoloration due
to airborne pollutants and is hydrolysis resistant. It can be
enlongated 4-7times and hark back after disengagement .
Elastane material includes 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.
Spandex is suggested to be enlongated 3-4times ,the most
significant elongation can be 5 times.
Spandex characteristics : Every yarn is made of several spun yarns which is uniform
tension. Less cost for elastic material as the high stess and high
High efficiency as the long time producing without outage.
No undesirable component on the surface. It makes less choking for
the hot melt adsive spraying as being without talc powder and other
Good performance on the tackiness of hot melt adsive. The glue for
the rubber can be used for Spandex and can be saved over 40%.The
creep-resisting shows excellent performance of Spandex
Spandex brings to baby more formfitting , comfortable beautiful,less
leakage and no skin irritant.
About 3kg per roll
Recilient force of ever Dtex(g/10000m) us 3 times than elastics
(0.024 force gram/unit)
Tage stress and strain curves is more smooth ,keeping smooth
resiliency force in the diffective area (20-30% elongation)
