Abstract
An instrument for measuring the friction and static electrification of moving yarns has been designed, constructed, and tested. The instrument allows measurements to be made on yarns over a wide range of speeds under a practically constant predetermined tension. The instrument also has applications for measurements of certain yarn me chanical properties. Some static electrification and friction studies are discussed. These have revealed some interesting effects which are not yet fully understood, such as reversal of the sign of transferred charge with change of speed and the unusually plastic behavior of nylon yarns in moving contact with surfaces.
