How do you test stretch and recovery for support fabrics?
We test stretch and recovery using controlled mechanical testing methods that simulate real wearing conditions. The goal is to confirm that the fabric returns to its original dimensions after repeated extension and does not relax or deform over time.
Our Testing Methodology
Stretch Limit Test
Fabric is stretched to a defined maximum percentage (e.g., 50–80% of width) to determine the full stretch range. This establishes the baseline for how much elongation the fabric can handle at a given force.
Immediate Recovery Test
After reaching the target stretch, the fabric is released and measured for immediate spring-back. High-performance support fabrics should return to within 3–5% of the original dimension within seconds.
Cyclic Fatigue Test
Fabric is stretched and released repeatedly (typically 10,000–50,000 cycles) to simulate weeks of wear. We measure how much permanent deformation accumulates over the cycle count.
Wash and Wear Simulation
Fabrics are laundered under controlled conditions and re-tested for stretch and recovery. This tells us how much support retention to expect after repeated washing over the product lifecycle.
What We Look For
- Stretch stays within target range at consistent force
- Immediate recovery > 95% after single stretch
- Minimal creep or bagging after cyclic testing
- Less than 5% loss in recovery after 10+ wash cycles
During sampling: We share stretch and recovery data for selected fabrics so you can compare options before making a final decision. This helps brands validate fabric behavior before bulk production begins.
