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 1. 5kgs per roll
Recilient force of every Dtex(840g/l 0000m) is 3 times than elastics(0.024foece, gram/unit)
The Stess and Strain curves is more smooth. Keeping smooth resiliency force in
the effective area (20%-30% elongation).
Wide elongation area. The uniform design specification of elastic force is from 2. 0-4. 0 times elongation.
The benefit of Spandex for manufacture
Less cost for elastic material as the high stess and high elongation.
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 dirt.
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
More comfortable
More beautiful
Less leakage
No skin irritant
Application: Elastic material for leg cuff and leackage stand.
