Abstract

The specific surface area (SSA) plays a significant role in pulp and paper technologies. Cellulose fibres from various natural sources were studied in both dry and aqueous state by molecular probe method in order to reveal how mechanical and/or chemical treatments affect the cellulose fiber structure and thus the SSA. The thickness of the investigated sheets and the lignin content of the fibres show only a negligible effect in dry state. In aqueous media the SSA exhibits. a 15-20 fold expansion. The effect of both mechanical and chemical treatments depends on the origin of the cellulose fiber in dry and aqueous states as well.
