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 (0.024foece, 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.
