Elastic Elongation & Recovery Test
Specimen: TWU98, 25g/m²
Base Material: 400% elongation spandex fabric
Lamination Parameter: 130℃ / 0.2MPa / 15s
Test Standard: ASTM D4964
| Stretching Cycles | Adhesive Layer Elongation | Recovery Rate | Bonding Interface Condition |
|---|---|---|---|
| 0 | — | — | Intact |
| 10 | 350% | 96% | No delamination |
| 100 | 345% | 95% | No delamination |
| 500 | 330% | 93% | Slight edge gap less than 1mm |
| 1000 | 300% | 90% | Minor crack, stretchable still |
Conclusion: It retains 93% recovery rate after 500 repeated stretches, perfectly suitable for frequently stretched parts of sportswear.
Peel Strength Variation After Repeated Washing
Specimen: TWU98, 25g/m²
Base Material: 200g/m² nylon spandex blended fabric
Lamination Parameter: 130℃ / 0.2MPa / 15s
Washing Standard: 40℃ household washing, 45 minutes per cycle
Test Criterion: ASTM D1876 T-type peeling test
| Washing Cycles | Peel Strength(N/25mm) | Strength Retention | Hand Feeling Change | Elasticity Variation |
