How to understand your test results

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

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)
