Abstract
A new technique for measuring the fibril angle of bleached pulp fibres is presented. It uses micro-Raman spectroscopy and involves measuring the ratio of the 1094 to 1120 cm-1 peak intensities as a function of angle. It is compared with a direct method of measuring of the fibril angle (cell wall striation method) and with two indirect methods (polarized light microscopy and pit aperture angle methods). A good correlation was obtained with the direct method indicating that the Raman method can accurately determine fibril angles in pine fibres. Poor correlations with the indirect methods suggest that these methods are inherently inaccurate.
