What amount of residual grease is tolerated on scoured wool?

To avoid jeopardising processes subsequent to scouring, a grease residue of 0.5 to 0.7 % (using SOXLETH extraction) is tolerated on the scoured fibre. With higher percentages of about 1.5 to 1.7%, special measures should be taken in the cardroom.
