Stretch Recovery Tester Static Method
Stretch Recovery Tester
A Stretch Recovery Tester Static Method is a lab instrument used to evaluate the stretch ability and recovery properties of fabrics, elastomers, or other stretchable materials. This method is crucial in textiles and material science to assess how well a material returns to its original shape after being stretched.
Key Functions of Stretch Recovery Tester Static Method :
– Measures elongation under a fixed force or length.
– Assesses the recovery percentage after a specified recovery time once the force is removed.
– Evaluates fabric’s resilience, durability, and comfort properties.
How It Works Stretch Recovery Tester Static Method:
- A sample is stretched to a predetermined extension or force.
- The stretch is maintained for a set period.
- After removing the load, the recovery (return to original length) is measured after a fixed time.
- The fabric sample is clamped and stretched to a specific length or force.
- It’s held for a fixed duration (e.g., 1–5 minutes).
- The tension is released, and the sample is allowed to recover.
- The recovered length is measured after a set time.
Main Components:
– Fixed clamps to hold the sample.
– Movable clamps for stretching.
– Precision scale or ruler for measuring elongation and recovery.
– Timing device (manual or digital) to control stretching and recovery periods.
– To assess elastic recovery and dimensional stability after stretching.
Applications:
– Used in testing knitwear, sportswear, elastic fabrics, and compression garments.
– Helps in product development and quality assurance.
Stretch Recovery Tester Static Method is designed to determine the stretch recovery property of elastic material by static method. 2.0mm thickness stainless steel frame and base board, makes the tester firm and stable. Sample holder can be slid along the guide rail smoothly and can be fixed at any position of the rail.
Test Scope：elastomeric material
Testing Standards：ASTM D2594、ASTM D3107, etc.
