Interpretive Summary: The interaction of water with cellulose in cotton fiber was investigated using Nuclear magnetic resonance techniques. Results indicate that water occupies the inter-lamellar spaces between layers of cellulose. These layers are 14-17 monolayers thick based upon nuclear spin diffusion results.
The interaction of water with cellulose and its influence on the nuclear spin dynamics in Gossypium barbadense (Pima) cotton were investigated by 1H and 13C solid-state NMR techniques. 1H spin diffusion results indicate that water is present in multiple layers within the cotton fiber, each layer being from 14-17 monolayers in thickness.
