Abstract
Near-infrared reflectance analysis as a tool for estimating clean wool fiber present in core samples of wool and mean fiber diameter was examined. Thirty-three commercial core samples and two years of ram fleeces were used in the research. Significant correlations were obtained between actual and predicted clean wool fiber present for both greasy and washed wool cores. Very close agreement between measured fiber diameter and estimated diameter from reflectance values was found. Orientation of the specimens was shown to influence reflectance values.
