Surface Studies of Fibre-Water Systems by Gas Chromatography

Abstract

The surface and interfacial properties of fibres and paper are important in the production and end-use of paper and board, and much attention has been paid to the nature of the interface between water-swollen cellulose fibres and the aqueous suspension medium. Much less attention has been paid to the equally important interface between fibres containing water and the atmosphere. The properties of this interface must range from those characteristic of a dry fibre to those of pure water, corresponding to water contents ranging from a fraction of a monolayer up to the fibre saturation value.
