Abstract
A NEW apparatus has been built for the measurement of the friction between two fibres. The principle is that two fibres are twisted a few turns, and the four fibre ends loaded with equal forces, P1. The load at one of the ends is increased until slipping occurs. If the necessary force is P2 and the (small) angle between the fibre ends, β, the coefficient of friction is given by the formula , where n is the number of turns. The apparatus will be described in detail elsewhere1.
