“…Resistance to compression is a very important factor between breeds. Among Merinos types, it accounts for most of the deviations from the very strong handle-diameter relationship [ 55 ] . It could be even more significant for fine or superfine wools.…”

Literature pertinent to fiber properties and handle of fine Merino lamb's and fleece wool is critically discussed. The softness of handle of fine Merino wool varies inversely with loose fiber resistance to compression. This complex raw wool parameter has geometric and mechanical attributes. Fiber bending and torsional rigidity are important mechanical factors that depend on mean fiber diameter, cross-sectional shape, and Young's modulus. Crimp frequency, amplitude, and form are equally important geometric factors. Those characteristics that distinguish lamb's and adult wool and appear to account for the relative softness of hand of lamb's compared with fleece wool are presented in Part II. ,

Resistance to compression is primarily a measure of the crimp structure of individual fibres. Fibre crimp, as distinct from staple crimp, has been shown to be an important aspect of wool quality with requirements depending on end use and processing conditions. A precise definition of its importance under various conditions must await further evidence.The consequences of these findings for Merino breeders depend upon the heritability of resistance to compression and its genetic and phenotypic correlation with other important wool characters. Estimates of such parameters are presented and used to formulate breeding plans for the Australian Merino. Follicle curvature was included among the characters studied because it was hypothesized that it would be as good a measure of fibre crimp as is resistance to compression. The results support this hypothesis. The most important conclusion is that, if textile requirements dictate that resistance to compression as well as fibre diameter must be controlled during Merino breeding, progress in clean wool weight will be severely restricted.
