The structure and mechanics of cellulose fibres are presented. Using Raman spectroscopy the molecular deformation of a wide-range of cellulose fibres are reported. These measurements of the molecular deformation are compared to X-ray diffraction measurements of the crystal deformation and conclusions are drawn on the possible morphology of cellulose fibres (series aggregate, hybrid series/parallel structures). It is shown that the use of Raman spectroscopy must be coupled with X-ray diffraction if a full-picture of the morphology, related to mechanical properties, is to be elucidated.
