This document specifies common methods for the quantitative microscopical analysis of various mixtures of fibres. The methods described are based on the use of a light microscope (LM) or a scanning electronic microscope (SEM), on the measurements of the fibre apparent diameter (preparation of longitudinal views) or on the measurements of fibre section area (preparation of cross views), depending on the section shape of the fibres.
The given procedures apply to fibres in any textile form when mixtures of fibres cannot be separated by manual methods or by chemical methods.
Examples of mixtures of fibres are cashmere and wool, cotton and flax, flax and hemp.
