Thus waste scour now yields: (i) zt^dolJibres, retained by the self-cleaning wool catchers ; (2) lanolin,recovered by centrifugalising, and utilised as a medicamentlike vaseline ; (3) wool fat or recovered grease, recovered bytreatment with sulphuric acid, either alone or in conjunctionwith lime ; (4) potash and illiuninating gas, obtained by con-centrating the scour and calcining the residue. Notwithstanding the expensive plant required for recoveringthese waste products and the time and trouble involved, theoutlay is very quickly repaid, especially when the waste liquorsfrom fulling mills are dealt with at the same time. At one time the scoured wool was rinsed by placing it inwicker lath baskets and immersing it in running water, 3o: TEXTILE RAW MATERIALS. a mill pool or mill sluice, where it was worked about withrakes or paddles until free from dirt.
