28—THE SORPTION OF WATER BY CELLULOSE AND EIGHT OTHER TEXTILE POLYMERS: PART II—THE SORPTION OF WATER VAPOUR BELOW 100°C BY TEXTILE POLYMERS OTHER THAN CELLULOSE

Abstract

Detailed results are presented on the absorption and desorption of water vapour (0—100% r.h., 30°—90°C) by cellulose triacetate, secondary cellulose acetate, ethyl cellulose, drawn nylon 6.6 yarn, Terylene, Orlon, wool and Fibrolane. The sorption characteristics of the samples were stabilized prior to the sorption measurements by means of several absorption–desorption cycles at 90°C. The sorption results are analysed, discussed and compared where possible with the results of previous workers. The isosteric heats and entropies of sorption are derived and discussed briefly.
