Abstract
The less frequently used methods of fibre identification are summarised, from elementary burning, staining and solubility tests, to density, melting point and refractive index determinations. More advanced instrumental techniques are explained: differential scanning calorimetry (DSC) and thermal analysis, thermogravimetric analysis (TGA), pyrolysis and briefly transmission electron microscopy (TEM). Scanning electron microscopy (SEM) is considered in some detail. Principles, specimen preparation, factors affecting the image and information obtained are considered. Advanced scanning electron microscopy techniques are noted, and the optimal instrument choice between the scanning electron and light microscopes compared.
