“…Others have variously reported that there is a positive, a negative, or no dependency of stress properties on wool fiber diameter [ 1,3,4,5,7,13,22 ] . Later in this paper it is shown that the several breeds exhibit markedly differing diameter dependencies.…”

Wools produced from five widely differing breeds of sheep which were raised under the same environmental and dietary conditions have been studied. By means of stress-strain analysis of wet fibers, certain mechanical properties have been evaluated and differences shown to exist among the several breeds, independently of differences in fineness among the wools. Wools from individual animals within breeds were also found to differ significantly in mechanical properties. The dependency of mechanical properties on the fineness of wool has been found to vary in a manner which indicates that crimp in the fiber strongly influences mechanical properties. Crimpy wools tend to have a negative dependency of mechanical properties on diameter, whereas the low-crimped wools tend to have a positive dependency of mechanical properties on diameter. Correlations have been established between the various properties studied, and high interdependencies have been found.

Lincoln 36s fibres, shrinkproofed by various rnethods, were examined microscopically, frictional measurements were carried out and whole fibre and cuticle-rich material were analysed for amino acids and amide-nitrogen. In all treatments, except alcoholic NaOH, fission of disulphide bonds is the primary chemical reaction which produces the necessary change of physical properties to eflect shrinkproofing, although there are other secondary reactions in at least two treatments.Shrinkproofing by degradative chemical methods is considered to be a function of modification of surface properties and of whole fibre properties. It is found that the eflicacy of shrinkproofing parallels the severity of surface modification observed by microscopy for all treatments in which there is little or no attack on the whole fibre. The other properties measured, viz., loss of cystine in cuticle or whole fibre and frictional properties, show no correlation with the degree of shrinkproofing.
