Abstract
THE theory of felting of wool in fabric form developed by Speakman and his collaborators1 postulates that under the repeated application of pressure the unidirectional migration of wool, due to its scaliness, is achieved by local extension and contraction of the fibres, and conditions which favour these processes promote milling shrinkage. In the course of the present investigations, a full account of which will appear elsewhere, it became clear that in felting the frictional properties of wool are as important, if not more so, than its extensibility and power of recovery.
