Key takeaways Anchor your workflow to recognised methods. Use IWTO-47  for wool diameter and IWTO-62  for length and diameter in tops and slivers for traceable results.   member.iwto.org +1 Build your quality system around ISO/IEC 17025  and report measurement uncertainty  using the GUM. This improves confidence and comparability.   ISO+1 Set calibration intervals based on risk, stability and use. NIST  does not mandate a single fixed interval.   NIST Use Interwoollabs IH Standards  for OFDA...

Key takeaways Accurate, rapid fibre data is foundational for circular fashion. It enables sorting, blending and verification across recycled and virgin inputs.   Textile Exchange OFDA2000 and OFDA4000 provide fast, standards-aligned measurements that help reduce rework and off-spec production.   OFDA+1 Recognised methods such as IWTO-47, IWTO-62 and ISO 137 support credible quality documentation and sustainability claims.   member.iwto.org +2OFDA+2 Recycled streams are variable.

Key takeaways Wool labs and mills use OFDA under recognised IWTO methods for diameter and, in tops and slivers, true length distribution.   member.iwto.org +1 Peer-reviewed alpaca studies show fibre diameter and variability are key selection traits, reinforcing the value of objective distribution data.   Frontiers New research identifies OFDA as a promising high-throughput tool for hemp fibre diameter measurement, supporting textiles and composites work.   Taylor & Francis Online+1 Flax...
