How Do Manufacturers Test Stretch and Recovery in Leggings?

Manufacturers can test leggings stretch and recovery by applying a defined load or extension to conditioned specimens and measuring how much length remains after a specified recovery period.

Test direction, repetitions, and wash condition affect the result and should be recorded. Finished-garment wear trials help identify bagging at knees or the waistband.

Ask for the agreed method, acceptance limits, and results for the actual production fabric rather than a generic supplier report.
