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 t

TL;DR (Summary Box) • The International Wool Textile Organisation (IWTO) sets global standards for sampling, testing and reporting (IWTO Wool Testing). • Accurate, repeatable fibre testing underpins fair pricing, trade credibility and fleece data integrity. • OFDA (Optical Fibre Diameter Analyser) enables objective fibre measurement (OFM) with high throughput and IWTO‑aligned workflows (overview in SGS OFDA technical note). • Labs and producers strengthen compliance via calib

When fibre measurements drive grading, contracts or genetics, method clarity matters. Two IWTO procedures sit at the centre of reliable results: IWTO-47 — measures the mean and distribution of fibre diameter using an Optical Fibre Diameter Analyser (OFDA). (member.iwto.org) IWTO-62 — determines fibre length distribution (true length) and diameter in wool top & slivers using the OFDA4000. (member.iwto.org) Below is a plain-English walkthrough of what each covers (and doesn’t),

In the world of wool and textile fibre analysis, precision isn't just a luxury—it’s essential. Accurate micron measurement plays a crucial role in determining the quality, usability, and value of fibres, particularly in the wool industry. Whether you're a grower, researcher, processor, or manufacturer, understanding fibre diameter down to the micron can influence every aspect of your operation. In this blog, we explore what micron measurement is, why it matters, how it's done

When you hear “OFDA,” diameter is probably the first metric that comes to mind. But there’s another equally important parameter: length measurement. Whether you’re processing Merino wool, hemp or recycled synthetics, accurate fibre length measurement influences yarn strength, fabric drape and machine efficiency. In this blog, we’ll unpack what length measurement entails, why it’s vital and how Optical‑based Fibre Diameter Analyser (OFDA) turns this data into a competitive edg
