Comparative Fiber Evaluation of the Mesdan Aqualab Microwave Moisture Measurement Instrument

Moisture is a key cotton fiber parameter, as it can impact the fiber quality and processing of cotton fiber.  The Mesdan Aqualab is a microwave-based fiber moisture measurement instrument for samples with moderate sample size.  A program was implemented to determine the capabilities of the Aqualab for rapid, precise and accurate cotton fiber moisture measurements.  Calibrations and operational protocols for the Aqualab were established, using the oven drying method by both the Scirocco and laboratory ovens as initial references.  The Aqualab results were compared to the moisture or water content results from various laboratory moisture instrumentation and measurement methods.  A comparative matrix for the different methods was developed.
