摘要
H-1 NMR has been used to study water dynamics in cellulose pulp. The reduction of water NMR line width with an increase of moisture content was observed. Different temperature dependencies of spin-lattice relaxation time were obtained for different origins of cellulose. Activation energies for different samples were calculated from the Arrhenius plots.
