24、2015 (E)3 ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for

25、 which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on a

26、ll matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. T

27、his document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any o

28、r all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users

30、 informationISO 16373-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile products, in collaboration with ISO Technical Committee TC 38, Textiles, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna

31、 Agreement).ISO 16373 consists of the following parts, under the general title Textiles Dyestuffs: Part 1: General principles of testing coloured textiles for dyestuff identification Part 2: General method for the determination of extractable dyestuffs including allergenic and carcinogenic dyestuffs

32、 (method using pyridine-water) Part 3: Method for determination of certain carcinogenic dyestuffs (method using triethylamine/methanol)DIN EN ISO 16373-1:2016-05 EN ISO 16373-1:2015 (E)4 IntroductionThe ISO 16373- series deals with dyes used in textiles for qualification and quantification.This part

33、 of ISO 16373 includes the definition of the classes of dyes, the description of some procedures to identify qualitatively the class of dyes used in textile material.The other parts of ISO 16373 are related to the quantification of some dyes. The principle of the test method in ISO 16373-2 is based

34、on the extraction using pyridine-water solution, which has been found to be the most efficient solution to extract a large range of dyes, including allergenic and carcinogenic dyes. The principle of the test method in ISO 16373-3 is based on the extraction using triethylamine-methanol solution. This

35、 solution has been found efficient to extract some dyes in some cases.Additional information related to the recovery rates (to characterize the extraction efficiency) obtained from the application of ISO 16373-2 and ISO 16373-3 are summarized in Annex B.It is important to note that there are other t

36、est methods related to azo dyes, for which a reduction of the extracted azo dyes leads to the release of some aromatic amines to be detected and determined using chromatography (See Bibliography/Aromatic amines determination).DIN EN ISO 16373-1:2016-05 EN ISO 16373-1:2015 (E)5 WARNING This document

37、calls for the use of substances/procedures that may be injurious to the health/environment if appropriate conditions are not observed. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety/environment at any stage.1 ScopeThis part

38、of ISO 16373 gives the definition of the colourant classes and the relationship to textile fibres.It describes some procedures to identify qualitatively the colourant class used in textile material.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this

41、breNote 1 to entry: The defining difference between a dye and a pigment is its solubility in an aqueous medium. In this part of ISO 16373, the term “affinity” is used as a qualitative expression, although affinity is the quantitative expression of substantivity and usually expressed in Joules per mo

42、le, where substantivity is the attraction between a substrate and a dye or other substance under precise conditions where the latter is selectively extracted from the application medium by the substrate.DIN EN ISO 16373-1:2016-05 EN ISO 16373-1:2015 (E)6 3.3pigmentwater-insoluble molecule which has

43、no dyeing affinity with fibreNote 1 to entry: The defining difference between a dye and a pigment is its solubility in an aqueous medium. In this part of ISO 16373, the term “affinity” is used as a qualitative expression, although affinity is the quantitative expression of substantivity and usually

44、expressed in Joules per mole, where substantivity is the attraction between a substrate and a dye or other substance under precise conditions where the latter is selectively extracted from the application medium by the substrate.4 Fibre identificationPrior to any colourant identification (including

45、dye class), the fibre nature of the textile product shall be known. The fibre nature may be based on information given by manufacturer, etc. or can be identified, using one or more techniques as described in ISO/TR 11827, for example.An explanatory table of colourants used in various textile materia

46、ls is given in Annex A.5 Dye classes, based on the method of applying the dye5.1 Acid dyeAcid dye is water-soluble anionic dye using neutral to acid dye baths. Attachment to the fibre (e.g. protein fibres and polyamide fibres) is attributed, at least partly, to salt formation between anionic groups

47、in the dye and cationic groups in the fibre.5.2 Metal complex acid dyeA metal complex dye is an acid dye that has a coordinate metal atom in its molecule.5.2.1 1:1 Metal complex dye1 molecule of dye is combined with 1 metal ion.5.2.2 1:2 Metal complex dye2 molecules of dye are combined with 1 metal

48、ion. 1:2 metal complex dyes are the most frequent.5.3 Azoic dyeAzoic dye is water-insoluble dye which is formed on the fibre by coupling a water-soluble diazo compound with a water soluble coupling compound having affinity for cellulose.NOTE 1 The definition of the class “azoic dye” (dyers classification) is distinct from the definition of the class “azo dye”
