Bending hysteresis measures how much resistance and residual set remain when polyester fabric is bent and released, helping explain drape and wrinkle behaviour.

Fabric anisotropy means polyester can behave differently in warp, weft and bias directions. Understanding it helps buyers control fit, drape, stretch and durability.

Bending stiffness explains why two polyester fabrics with the same GSM can feel very different in drape, structure and garment movement.

Learn how drape is evaluated in polyester fabrics, what buyers should check, and how to document reliable quality results before bulk orders.
