Stretch percentage
Stretch percentage describes how far a fabric can extend from its relaxed dimension under a defined method and load. The result depends on test direction and method, so a percentage without a method is incomplete.
Stretch recovery
Recovery describes how well the fabric returns toward its original dimension after extension. Two fabrics can show similar elongation but behave differently after repeated wear or loading.
Write the requirement clearly
Specify wale and course direction where relevant, target elongation, recovery expectation, conditioning and test method. For close-fitting garments, confirm opacity and recovery on the intended pattern as well as on a laboratory strip.
Final fabric suitability depends on the approved specification, processing route, garment construction and agreed test requirements.
