| Resumen: | This document specifies a test method for the detection and determination of the content of dyes in methanol extracts. This test method is applicable to all types of textile products consisting of natural or man-made dyed fibres, e. g. fibres of animal origin, cellulosic fibres, polyesters, polyamides, acetates and triacetates, polyacrylics, viscose and other dyeable fibres. The method is not applicable to fibres of elastane and elastodiene, but to blended fabrics containing these fibres. This is a conventional method; altered extraction conditions lead to deviating results. |
