Abstract
The adsorption isotherms of water vapour on a wide range of commercial secondary cellulose acetate and cellulose triacetate fibres have been measured at 22°C. Conversion of cellulose acetate flake into fibres causes a drop in sorption, but otherwise the sorption is almost unaffected by the filament denier, conversion into staple fibres, solution-dyeing, or delustrant. Stretchspinning, as in the production of Fortanese, alters the shape of the adsorption isotherm to the sigmoidal type. Cellulose triacetate fibres, e.g., TriceU Arnel, (Tourpleta, have accessibilities to water vapour of 0·75—0·85. Desorption isotherms have also been determined for several secondary acetate and triacetate fibres.Keywords
