M. de  aImplications of Medullation and Fibre Diameter Distribution on Wool Diameter Measured by Airflow.  c1992  aThe specific gravity (related to medullation as assessed by three techniques) and fibre diameter variability of 242 wool samples (encompassing the range of diameters between 22.0 and 38.0 m.m) were considered to evaluate the accuracy of diameter estimates as obtained from the Airflow apparatus. Data are presented showing the improvement obtained on diameter estimates of highly medullated wools, within a precision comparable to others reported for non-medullated fibres. Results on the techniques employed lo assess medullation (Projection Microscope, Medullameter and InfraAlyser) have also been discussed.  asheep  aspecific gravity coefficient of variation1 aKENNEDY, J.
