Introduction

The correct identification of fibres in textiles and the accurate determination of the composition of each fibre present is a legal requirement in many countries throughout the world for imported textile goods and at the point of sale to the public. Fibre identification can be carried out by a number of different techniques, e.g.

microscopy, solubility, spectroscopy, melting point, pyrolysis, density, refractive index, etc.
