Two polyester fabrics can have similar GSM and even similar bending stiffness, yet one springs back after folding while the other keeps a visible set. The difference can be explained by bending hysteresis.
What Is Bending Hysteresis?
When a fabric is bent and then released, the force required during bending does not always follow the same path during recovery. The gap between those paths is called hysteresis. A larger gap generally means more internal friction or structural resistance to full recovery.
Why It Matters
Bending hysteresis influences how easily a garment forms folds, how quickly those folds disappear and how fluid or crisp the fabric feels in motion.
What Changes the Result?
- Yarn texture and twist
- Fabric density
- Heat setting
- Coatings or finishes
- Brushing or surface treatment
Buyer Relevance
Uniforms, skirts, lightweight jackets and fashion fabrics may need different bending behaviour. A fabric that is too resistant can feel boardy; one with excessive residual set can look wrinkled or tired.
What to Compare
Do not use GSM alone. Compare bending stiffness, recovery behaviour and the actual garment drape after pressing, folding and wear simulation.
Final Takeaway
Bending hysteresis explains why “how a fabric bends” and “how it recovers” are not the same thing. It is a useful concept when selecting polyester for garments where shape and drape matter.
