Inter-fibre Cohesion Behaviour of New Zealand Wools

Inter-fibre cohesion is regarded as being an important property of assemblies such as slivers, made of wool or any other fibres, with respect to processing in carding, drawing (gilling) and spinning. In this paper results of multiple regression analysis, and their validation, are presented to show that a strong relationship exists between the sliver cohesion (measured as sliver tenacity and sliver specific energy to break in a long-gauge tensile test) and a combination of the standard wool properties, such as bulk, mean fibre length (Barbe), mean fibre diameter and medullation content, used for the objective blend specification of New Zealand wools for marketing and processing.
