Abstract
A new experimental approach is described for obtaining a quantitative measure of the wettability of filaments. This technique is based on the spontaneous capillary rise of liquid between two filament surfaces held in an adjustable v-shaped arrangement. No contact angle measurements are necessary, all information being obtained from simple length readings. The apparatus allows a filament sample to be tested in different liquids and conditioned without being removed from the test mounting. Results are expressed in terms of the free energy of wetting. Some dependency on filament spacing at the liquid source level has been observed, but none connected with the angle between them.
