3.Characteristic
1). Every yarn is made of several spun yarns which is uniform tension.
2). Recilient force of every Dtex(g/10000m) is 3 times than elastics (0.024 force,gram/unit).
3). The Stress 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.
4.Advantages:
1). To the skin of human body not produce allergic.
2). retraction force of Elasticity softly, no tight feeling to human skin, keep the blood circulating fluid.
3).To certain high temperature resistant, the long storage circle of the products made e.g. Sanitary napkin, diaper.
4).To meet the requirements of health industry for moderate elastic, creep resistance, aging resistance.
