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.
