Abstract

The use of dielectric measurements of cotton fibers as a method of measuring the mass of a fiber bundle would eliminate the tedious and time-consuming manual operation of weighing the fiber bundle. The dielectric properties of various cotton varieties were measured using several measuring frequencies for ranges of fiber moisture content and sample pack ing density. For a fiber moisture content greater than the equilibrium moisture content at 10% RH, it was found that there is a significant variation in the dielectric properties between varieties of cotton. As the fiber moisture content approaches zero, the variation between varieties diminishes. At zero fiber moisture content, the variation between varie ties becomes insignificant. At zero moisture content, it was found that it is possible to use dielectric measurements as a reliable measure of the mass of a fiber bundle.
