27—ELECTROSTATIC CHARGING ON FABRICS AT VARIOUS HUMIDITIES

Abstract
Electrostatic-charge generation was measured on four different fabrics at relative humidities ranging from 0 to 65%. The sorption isotherms were also determined. For all fabrics, a maximum in the charge-generation curves was found to occur at a relative humidity corresponding to W m (the moisture content when a monomolecular layer of water is completed on the surface). These results are explained with reference to the sorption isotherms.
