Fibre surface composition Information about the chemical structure of fibre surface is important when investigating the effect of delignification reactions on the components in pulp fibre surface layers. A more detailed understanding about the interactions between the fibres is also desirable. Electron microscopy for chemical analysis (ESCA) is a very suitable tool for such investigations.
