Scoured Wool

Scouring is the process of preparing and washing a batch of raw sheep's wool to remove impurities such as grease, dirt and suint. AWTA Raw Wool is able to perform the certified testing of scoured and carbonised wool for Wool Base, Vegetable Matter Base and Mean Fibre Diameter.



A further, separate test called a Condition Test is used to determine the oven dry mass and calculated invoice weight of a batch of scoured or carbonised wool. The purpose of a Condition Test is to determine the average moisture content, or regain, of batches of scoured or carbonised wool.

An IWTO Conditioning Certificate is issued that certifies the invoice mass that the batch of wool would have if its average regain were of a specified standard value.
