Deformation mechanism of cellulose gels. III. Changes in orientation upon drying

The orientation of model filaments stretched to various extents in three different states of swelling was investigated by quantitative x‐ray analysis before and after drying. The change in orientation upon drying was found to be either very small or zero. This shows that the crystallites do not even approximately follow the rules of affined transformation which would require a very considerable increase in orientation on drying. There must be an entirely different mechanism which prevents the crystallites from being dragged along with the matrix in which they are embedded.
