Effect of Atmospheric Humidity and Temperature on the Relation Between Moisture Content and Electrical Conductivity of Cotton
01 October 1933
HE data given in this paper show the effect of successive equilibrium humidity cycles on the relation between (a) relative humidity and moisture content; (b) insulation resistance and relative humidity; and (c) insulation resistance and moisture content, for raw and water-boiled cotton at constant temperature (25° C.). These data have been of considerable assistance in explaining the behavior of cotton, particularly the fact that its d.-c. insulation resistance, when measured at some definite test condition, 1 is dependent, to a surprising extent, upon previous treatment, e.g. the manner in which wet cotton is dried, temperature of drying, and the atmospheric conditions to which it is exposed after drying, before being measured under the comparable test condition.
