Interpretive Summary: The moisture content of cotton fiber is an important fiber property, but it is often measured by a laborious, time-consuming laboratory oven drying method. A program was implemented to establish the capabilities of a laboratory microwave moisture measurement instrument to perform rapid, precise and accurate fiber moisture measurements. The microwave instrument was calibrated versus two significantly different oven drying methods. The method agreements between with two oven drying methods were very good, with low residuals observed. The precision of the microwave moisture content measurements was very high, approaching 0.1% moisture. The impact of sample fiber weight was minor, and instrument stability and long-term repeatability was excellent. The microwave fiber moisture content measurement was shown to be viable and applicable for quality control use.
