A Method Of Determining Grease And Dirt In Wool Classic Reprint

Excerpt from A Method of Determining Grease and Dirt in Wool Before the scouring process, all samples of wool are brought to a constant-moisture content. In the moisture experiments here reported, 20 per cent moisture was the largest percentage for any of the samples used. When there is no more than 20 per cent moisture in air-dry samples, it has not been found necessary to condition them longer than three hours nor at a temperature higher than 50 C.
