What do you get?
SGS provides a test report describing wool quality and quantity. Samples are submitted without the need for independent sampling and weighing. Benefit from:
- Accurate fleece testing, including micron (average diameter), staple length and strength, length-diameter profile and yield
- Quality and quantity certainty – for both the buyer and seller
- Valuable info on how to process the efficiently
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
