J.F. Waterhouse. The role of pressing in wet-web saturation. In Fibre-Water Interactions in Paper-Making, Trans. of the VIth Fund. Res. Symp. Oxford, 1977, (Fundamental Research Committee, ed.), pp 419–434, FRC, Manchester, 2018.


Wet-web saturation, a process developed for the addition of polymer
to fibrous networks, involves three distinct stages:

(1) Web consolidation and water removal by wet pressing.
(2) Latex saturation of the wet-web by capillary and hydrostatic forces.
(3) Redistribution and removal of excess latex by squeeze rolls.

The results presented in this paper are part of an ongoing programme to gain a
better understanding of the saturation process and its influence on the properties
of polymer impregnated networks. This experimental investigation using a laboratory press is concerned with the saturation process (primarily pressing) behaviour of wood pulps in the basis weight range of 250-1 500 g/m².
