Spandex or elastane is a synthetic fiber known for its exceptional elasticity. It is strong, but less durable than its major non-synthetic competitor, natural latex. It is a polyurethane-polyurea copolymer that was invented in 1959 by chemists C. L. Sandquist and Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia
Spandex use for leg cuff , keep leakage protection for diaper
Characteristic of Spandex.
1,Every yarn is made of several spun yarns which is uniform tension.
about 3kgs per roll
2,Recilient force of every Dtex(g/10000m) is 3 times than elastics (0.024foece,gram/unit)
3,The Stess and Strain curves is more smooth. Keeping smooth resiliency force in the effective area (20%-30% elongation).
4,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 and 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
