Abstract
An account is given of a pilot-scale investigation into the processing significance of the location of the zone of weakness found in greasy-wool staples with different staple strengths. Experiments involved processing sixteen single-bale batches to top. Twelve of these batches included all combinations of four levels of staple strength (20, 30, 40, and 50 N/ktex) and three positions of weakness (tip, middle, and base).
Differences in processing were found between batches whose position of weakness was in the middle of the staple and those that had either a tip or a base break. The effects due to position of weakness were manifested principally in the resultant fibre-length distribution of the tops, and this was observed even at high levels of staple strength. However, the effect of position of weakness on Hauteur of the tops and on the losses or noils was overshadowed by the influence of the level of staple strength.
