Results are presented for the standard deviation of fiber diameter in sale lots of merino and crossbred fleece wools and skirtings. There is a strong positive association between standard deviation and average fiber diameter in all cases. In merino f

Some effects of the test-specimen-preparation procedure on resistance-to-compression measurements on clean and carded raw wool are reported. The results show the importance of controlling the regain of the wool, the time between carding and measureme

Procedures for recording the proportion of coarse fibers in greasy wool sale lots were compared. The percentage of fibers greater than 1.5 times the mean provided an estimate of the coarse edge that was precise and not particularly sensitive to outli

Experiments are reported in which the differences in lightness and yellowness that could be visually observed in daylight for pairs of carded-wool samples were related to the differences in colour measurements. The fifteen observers who took part cou

The molecular mechanical constant α which is directly related to flow hole volume is calculated for wool fibers exhibiting a range of stress-strain properties. It is found that the value of the stress developed at 30% strain (S30) is invesely propor

The variations in plasticity among the fibers of a single staple of wool have been shown to be associated with variations in swelling in water and in 100% formic acid; as a rule, fibers with the lowest plasticity (primary follicles) show the least sw

Load-extension, supercontraction, set. and post-yield creep characteristics of two different fiber types containing reduced methylated, reduced re-cross-linked, and normal disulfide bonds are presented. A close relationship is observed between the ex

Extremely large variations occur in the compressional properties of wool samples. These variations are attributed to differences in the crimp structure of the fibers, crimp form and crimp frequency together accounting for 88.6% of the observed varia

Large variations in the felting rate of loose wool are attributed, principally, to crimp characteristics of the single fibers. Crimp form alone accounts for 77.4% of the variation and, in combination with the directional frictional effect, for 83.3%.
