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.

Technical Abstract: 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.
