Step 1: Understanding Drape Coefficient.
Drape coefficient is a numerical value between 0 and 1 (or 0% to 100%), indicating the extent to which a fabric resists draping.
Higher drape coefficient ⇒ less drape ⇒ stiffer fabric.
Step 2: Interpretation.
A low drape coefficient means the fabric is soft and flows easily.
A high drape coefficient means the fabric is stiff and resists forming folds.
