28、roductionThe ISO 16373 series deals with dyestuffs used in textile for qualification and quantification.ISO 16373-11)includes the definition of the dyestuff classes and the description of some procedures to identify qualitatively the dyestuff class used in textile material.The other parts of ISO 163
29、73 are related to the quantification of some dyestuffs.In this part of ISO 16373, the principle of the test method is based on the extraction using pyridine-water solution, which has been found to be the most efficient solution to extract a large range of dyestuffs, including allergenic and carcinog
30、enic dyestuffs.In ISO 16373-3, the principle of the test method is based on extraction using triethylamine/methanol solution. This solution has been found efficient to extract some dyestuffs in some cases.Additional information related to the recovery rate (to characterize the extraction efficiency)
31、 obtained from the application of ISO 16373-3 and this part of ISO 16373 will be summarized in ISO 16373-1.It is important to note that other test methods exist related to azo dyes, for which a reduction of those extracted azo dyes leads to the release of some aromatic amines, to be detected and det
32、ermined using chromatography.The percentage of recovery using the method of this part of ISO 16373 is shown in Annex F for the dyestuff classes (to be defined in ISO 16373-1) acid, basic, direct, disperse, solvent dyestuffs and “mordant dyestuffs” on different textile fibres.1) To be published.
