✦ Synopsis

A means to quantitatively construct two layer models of the wood cell-wall utilising basic density and mean microfibril angle data is discussed. It is assumed that the lignin distribution is uniform in the secondary wall layers, that there is a fixed polysaccharide ratio throughout the wall and that variation in wall thickness arises only from variation in $2 layer thickness. It is shown that the relative thickness of those cell wall layers in which the cellulose is transversely oriented (M + P, $1 and $3) have a significant effect on longitudinal shrinkage and that variance between computed and measured shrinkage values is reduced when compared with earlier models if both basic density and mean microfibril angle are taken into account.
