Relationship Between Various Surface Properties of Wool Fibers: Part II: Frictional Properties

Wool fibers were treated with alcoholic potash for different periods of time. The anti-scale and with-scale coefficients of friction were measured by means of a modified fiber twist friction meter. The with-scale friction increases with time of treatment, and this is explained in terms of a chemical modification of the epicuticle. There is a close relationship between friction and breaking strength of top and between friction and felting rate.
