Nonwoven Strength Is Bond Density
The claim
Nonwoven strength rises sharply above a threshold bond density and plateaus beyond it, rather than scaling smoothly.
01The mechanism
Below threshold, the fibre network is floppy and load paths are few; above it, a spanning network forms and further bonds add little.
02Predictions
- P1Strength should jump at a bond density.
- P2Additional bonding should saturate.
03Refutation
Smooth strength scaling with bond density would remove the threshold.
