This document specifies a method for identification and quantification of certain dyestuffs in methanol
extracts of textile and textile products using liquid chromatography (LC).
The document is applicable to all types of textile products consisting of natural or man-made dyed
fibres, e.g. fibres of animal origin, cellulose-based fibres, polyesters, polyamides, acetates, triacetates,
polyacrylics, viscose and other dyeable fibres. The method is not applicable to fibres made of elastane
and elastodiene, but is applicable for blended fabrics containing these fibres.
This is a conventional procedure; modified extraction conditions lead to deviating results.
