1. Greasy Wool
Greasy wool is the raw fibre harvested from sheep during shearing, before it is cleaned during the scouring process. Greasy wool is sometimes called 'raw' wool.
2. Scoured Wool
Sourced wool is the term given to greasy wool that has been washed to remove contaminants, such as dirt, dust, sweat (suint) and wool grease. The wool grease is recovered and from it lanolin is extracted and used in products, such as cosmetics.
3. Carbonised Wool
Carbonised wool has undergone an additional cleaning process (carbonising) to remove vegetable matter, such as seeds, burrs and grass. Carbonising is only used in the woollen processing system, not the worsted processing system.
4. Wool Top
In the worsted processing system, three steps - carding, gilling and combing - turn the scoured wool into a 'top' or combed sliver. This collection of aligned fibres, without twist, is now ready for spinning into yarn.
