SGS Wool Testing Services provides independent testing for wool and animal fiber traders, processors and growers. Testing is performed on greasy, scoured wool and carried out to internationally proven International Wool Textile Organisation (IWTO) test methods. The IWTO is an organization created to support fair trading in the wool industry as a whole, from woolgrowers to wool textile traders, processors, spinners and weavers.

How to understand your test results

  • Yield

    Determining the amount of clean wool (wool base), and vegetable matter contamination in a sample

  • Mean fiber diameter

    The average fineness of the wool (fiber thickness), which is a primary determinant of wool value

  • Color

    Measured as tristimulus values, and normally used to assess clean color brightness (Y value) and yellowness (Y-Z value)

  • Staple length and strength

    We use the average staple length, staple strength and position of break to assess the performance of apparel wools in the worsted processing system

  • Bulk

    This measures the fibers’ ability to fill space and also relates to resilience, which are important properties for applications such as carpets, futons, and insulation

  • Fiber curvature

    Relates to bulk, compressibility, and crimp and is cited as an influence on processing

  • Fiber diameter distribution

    Information about aspects of the diameter distribution may affect assessments of comfort and processing performance

  • Medullation

    Refers to the hollow fibers in wool and other animal fibers, which causes uneven dye uptake and adversely affects appearance in apparel wools (but may be desirable for some carpet types)

  • Conditioned mass

    Wool absorbs up to 20 percent of its weight as moisture, so invoicing is based on an agreed moisture content or regain (known as the conditioned mass)

  • Length After Carding (LAC)

    A standardized method of simulating semi-worsted processing to estimate mean fiber length after processing. Results Are expressed in Hauteur, Barbe, and length distribution statistics
