Term Definition
Combing wool
Wool suitable for conversion to yarn on the worsted system. Generally, it is Merino wool having a staple length of about 40mm or greater.
Comfort Factor
The percentage of fibres in a distribution that are finer than 30 micron in diameter.
Conditioning

The amount of moisture (16%) absorbed by dried wool from standard atmosphere referred to as regain.

Consistency
The uniform distribution of all the fibre characteristics within each lock and throughout the entire fleece.
Contamination

Foreign items found in wool that affects processing that falls into two categories: (1) Fibrous - baling twine, dogs hair, feathers, fertilizer bags etc. These contaminants behave just like the wool fibre and end up woven into finished fabrics and (2) Hard - metal or hard substances such as bale hooks, tools, tyre levers, timber etc. which if undetected cause costly damage to early stage processing machinery that usually require production lines to close while being repaired.

Core sampling
Removing fibre specimens for testing by inserting a hollow tube into each bale.
Core Testing
Consists of testing a known quantity of wool for yield, fibre diameter and vegetable matter content and type; the sample is extracted from a bale of greasy wool, by means of a core of tube. Core tests are usually conducted prior to sale (pre-sale).

Crimp Frequency
The number of crimp waves per centimetre of staple length. Coefficient of variation of crimp frequency refers to the variation in frequency between staples within a lot.
