    The water vapor sorption behavior of a range of natural fibers (jute, flax, coir, cotton, hemp, Sitka spruce) has been studied. The data was analyzed using the Hailwood Horrobin model for isotherm fitting and determination of monolayer moisture content. The extent of hysteresis exhibited between the adsorption and desorption isotherms was dependent upon fiber type studied and was larger with high lignin compared to low lignin content fibers. The area bounded by the hysteresis loop decreased as the isotherms were performed at progressively higher temperatures. This behavior is consistent with sorption interactions occurring with a glassy solid below the glass transition temperature. The Hailwood Horrobin model was found to provide good fits to the experimental data.
