20、:2015(E)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 wh
21、ich 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 all
22、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. This
23、 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 or a
24、ll 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 an

26、formationISO 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 Ag
27、reement).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 (m
28、ethod using pyridine-water) Part 3: Method for determination of certain carcinogenic dyestuffs (method using triethylamine/methanol)iv ISO 2015 All rights reservedBS EN ISO 16373-1:2015ISO 16373-1:2015(E)IntroductionThe ISO 16373- series deals with dyes used in textiles for qualification and quantif
29、ication.This part 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
30、16373-2 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 dyes, including allergenic and carcinogenic dyes. The principle of the test method in ISO 16373-3 is based on the extraction using triethylamine-methan
31、ol solution. This 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
32、there are other test 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).

In this part of ISO 16373, the term “affinity”
38、 is used as a qualitative expression, although affinity is the quantitative expression of substantivity and usually 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

41、e 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 dye class), the fibre nature of the textile product shall be known. The fibre nature may be base
42、d 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 materials is given in Annex A.5 Dye classes, based on the method of applying the dye5.1 Acid dyeAcid dy
43、e 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 in the dye and cationic groups in the fibre.5.2 Metal complex acid dyeA metal complex dye is an
44、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 ion. 1:2 metal complex dyes are the most frequent.5.3 Azoic dyeAzoic dye is water-insoluble dye
45、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” (see Clause 6, chemist classificat
46、ion).NOTE 2 For the French version, the term “azoic dye” should be translated by “colorant azoque insoluble” (known as well as “colorant naphtol”) in order to make a clear distinction with the translation of “azo dye” by “colorant azoque”.5.4 Basic dye (also called cationic dye)Basic dye is water-so
47、luble cationic dye using neutral to acid dye baths. Attachment to the fibre (e.g. acrylic) is attributed, at least partly, to salt formation between cationic groups in the dye and anionic groups in the fibre.2 ISO 2015 All rights reservedBS EN ISO 16373-1:2015ISO 16373-1:2015(E)5.5 Mordant dyeDye ca

The very fine particle size gives a large surface area that aids dissolution to allow uptake by the fibre.5.8 Reactive dye5.8.1 GeneralReactive dye contains specific re
