Senator ALLAN MacDONALD asked the Minister for Supply and Development, upon notice -

1.   To what extent is wool being rough or semi-scoured in Australia so as to retain certain quantities of natural grease?

2.   Has the Council for Scientific and Industrial Research any information as to the increased durability or warmth of such wool?

Senator McBRIDE (SOUTH AUSTRALIA) - The answers to the honorable senator's questions are as follows : -

1.   All wool being scoured for and on behalf of the Central Wool Committee under the Imperial Wool Purchase arrangement is scoured practically free of grease content. In New South Wales and Queensland, some lower grade wools are treated by what is known as tank washing and this method of treatment leaves from 8 per cent, to 10 per cent, of grease in the wool.

2.   The Council for Scientific and Industrial Research has some literature on the subject but has conducted no experiments.
