The capability of instruments such as SIROLAN-LASERSCAN™ (LASERSCAN) and OFDA100 to provide measurements of fibre curvature has resulted in increased interest, within Australia among wool producers and exporters, and among overseas top-makers and spinners. However, the metrology of fibre curvature measurement by these instruments is poorly understood. Standardized conditions for preparation, and measurement procedures that stabilize the curvature of the wool fibres prior to measurement by either instrument, are yet to be defined.
Based on its strong association with crimp frequency, wool fibre curvature measurement holds promise as a specification, which can be used to add value to wool in production, trading and processing…
