Drape Is a Bending Ratio
The claim
Fabric drape is set by the ratio of bending stiffness to weight, so a heavier fabric can drape better than a lighter one.
01The mechanism
Drape is the balance between gravity and bending resistance; the ratio, not either term, sets the form.
02Predictions
- P1Drape should collapse onto the ratio.
- P2Heavier low-stiffness fabrics should drape well.
03Refutation
Drape tracking weight would remove the stiffness term.
