The Effect of Moisture Content on the Optical Mass of Cotton Beards

C. K. Bragg, J. D. Wessinger and J. P. Gourlot


Fibrograms were obtained for cotton beards used in HVI testing after conditioning the beards in two different relative humidity environments, 30% and 65%, where the temperature was controlled to a nominal 70 degrees F. The differences in optical mass measurements for the fibrograms were negligibly small and close to the resolution of the optical system of the instrument. From these results it was concluded that the optical measurements used as indirect indicators of mass for HVI strength measurements are relatively invariant to moisture content.
