Fibre saturation point
Encyclopedia
Fibre saturation point is a term used in wood mechanics and especially wood drying
, to denote the point in the drying process at which only water bound in the cell walls remains - all other water, called free water, having been removed from the cell cavities. Further drying of the wood results in strengthening of the wood fibres, and is usually accompanied by shrinkage. Wood is normally dried to a point where it is in equilibrium with the atmospheric moisture content or relative humidity, and since this varies so does the equilibrium moisture content

Wood drying
Wood drying reduces the moisture content of wood before its use.There are two main reasons for drying wood:...

Equilibrium moisture content
The moisture content of wood below the fibre saturation point is a function of both relative humidity and temperature of surrounding air. The equilibrium moisture content is the moisture content at which the wood is neither gaining or losing moisture; this however, is a dynamic equilibrium and...
