Sorption of Nitrogen and Water Vapor on Textile Fibers 1

:-Ieas urements were made of the adsorption of nit rogen and water vapor on six purified text ile fibe rs and t itaniu m dioxide. It was found that all of t he fi bers had a relatiYely low capa city for the adsorption of nitrogen as compared with t h c capacity for t h e adsorption of ,,'ater vapor. T he surface area values ranged from 0,31 sq uare meter per gram for nylon to 0.98 square meter per gram for dscose rayon. The val ues of t he free surfa ce energieR of adsorp t ion as calculated by the Gibbs adsorption equation \\"ere t he same for wool, cotton, silk, and rayon fibers b u t differed for t he two synthetic polymers , nylon and acetate rayon.
