Abstract
By use of a novel commutator method, triboelectric potentials produced by rubbing cotton with various materials have been measured by comparison with known D.C. potentials. Results are given here for fiberboard (phenolic resin laminate, fabric base), cork roller material, syn thetic rubber roller material, Lucite, polystyrene, glass, and cellulose acetate sheet, used as rubbing materials on three varieties of cotton and trash extracted from baled cotton. The purpose of this study was to learn if the sufficiently great differences in triboelectricity produced by cot tons and trash could be used practically in the electrostatic cleaning of cotton.
