Theory 073/Textiles & Fibres
Dye Uptake Is Crystallinity
The claim
Dye uptake is set by the amorphous fraction of the fibre rather than by dye concentration.
01The mechanism
Dye diffuses into amorphous regions only; crystalline regions exclude it regardless of bath concentration.
02Predictions
- P1Uptake should track amorphous fraction.
- P2Higher concentration should not penetrate crystalline regions.
03Refutation
Uptake tracking concentration would remove the structural term.
