Assessing the moisture uptake behavior of natural fibres
K.-Y. Lee and A. Bismarck, Imperial College London, UK
Abstract:
Various methods for the determination of moisture uptake and water sorption behaviour of natural fibres are discussed; namely through simple weight gain measurement and dynamic vapour sorption (DVS), respectively. Simple weight gain measurement provides the equilibrium moisture content at a specified relative humidity. DVS, on the other hand, provides water sorption/desorption behaviour of natural fibres. Not only can the water sorption behaviour of natural fibres be determined, water sorption hysteresis can also be studied. A novel method of determining the accessible hydroxyl groups utilising heavy water using ...
