Key takeaways Fibre curvature describes how strongly a wool fibre bends and is commonly reported in degrees per millimetre. Both OFDA and Laserscan can report it.   Woolwise+1 Curvature correlates with crimp character and contributes to fabric handle, bulk and processing behaviour.   PMC In Australia, micron, yield, staple length and strength remain the primary price drivers, with curvature influencing demand indirectly via processing performance and style.   MSSANZ+1 OFDA instruments...

Key takeaways Laserscan  is the IWTO-12 reference for mean fibre diameter and distribution, widely used for certification.   IWTO Member Area OFDA  is covered by IWTO-47 for mean fibre diameter and distribution, and can capture curvature in the same run.   IWTO Member Area+1 Airflow  provides an indirect mean diameter based on resistance to air flow and is codified for raw wool as IWTO-28.   International Wool Textile Organisation+1 Interwoollabs IH Tops underpin calibration for all three...
