The valuation of superfine wools in relation to their topmaking performance

In this pilot study, superfine wool fleeces were identified that, based on their visual appearance, were receiving premiums or discounts in the raw wo ol market. Fleeces from these two groups were subsequently processed and th eir topmaking performance compared. The estimated mean price for the 'premi um' fleeces was 1737 c/kg clean compared to the estimated mean price for th e 'discount' fleeces of 1285 c/kg clean. Compared to the 'premium' fleeces, the 'discount' fleeces were similar in all raw wool measurements except th at the 'discount' fleeces were longer (15 mm) and of lower crimp frequency (1 cr/cm). These differences in raw wool properties were reflected in the t op specifications and processing performance of the two groups of fleeces. There were significant differences between the two groups of tops with the 'discount' group 9 mm longer in Hauteur, 4% greater in CVH, 3% less in noil and 11 deg/mm less in fibre curvature. Despite the visual difference in ra w wool colour between the two groups, there was no difference in colour of the tops. It was concluded that wools of the same mean diameter that were less stylis h and consequently substantially cheaper, processed into tops of similar if not superior quality. Therefore, paying large premiums for superfine wools with visual characteristics that play little to no role in processing must be questioned. Wool is in a highly competitive market. To maintain market share, efficient production and pricing mechanisms are required. We suggest that the premiums paid for certain superfine wool types results in no topm aking advantage, distort the market towards inefficient sheep and wool prod uction systems, and consequently significantly reduce wool's competitive po sition.
