Features
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 (0.024foece,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.
Application
1). In the application of sanitary napkin
Mainly used for 3-D part, While a spandex yarn, leak proof effect.
2). In the application of nappies
Both side of the parts, part two, total four. It has leakproof constrictive effect, and avoiding the discomfort of the user.
3). In the application of diaper
Usually used in part of the legs and 3 d best. The leg part commonly use three or four and the 3d part use two spandex yarn |
