Foreword
ISO (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 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 all 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 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 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

ISO/DIS 2076:2025(en)
Introduction
The objective of this document is to propose a generic name of fibre (a generic name is unique by nature)
within the framework of the ISO standardization for the textile products. It has been elaborated in order to
present a compilation of generic names and the rules to create a new generic name for new fibres.
[1] [3]
It is intended to be the reference for the ISO 1833 series and the Technical Report ISO/TR 11827 .
It can be used as a reference within the framework of the globalization since compilation of the generic
names of man-made fibres is important for the global distribution of textile products due to national
regulations for the declaration of fibre content and care labelling. It can be an answer to a universal need for
the standardization of generic names that would foster easy movement of textiles across borders to facilitate
trade, for example, for companies which might have plants in multiple countries and have innovations and
business activities covering research and development in fibre-producing.
This document can be helpful for the coordination of national or regional authorities (for examples, FTC in
the USA, European Commission in European Union, etc.) within the framework of regulations. Annex F links
the generic names to the specific requirements regarding some national or regional regulations.
For example, products destined for the European market are labelled in accordance with the regulation
identified as Regulation (EU) No. 1007/2011 of the European Parliament and of the Council of 27 September
2011 on textile fibre names and related labelling and marking of the fibre composition of textile products.
Regulation 1007/2011 repeals Council Directive 73/44/EEC and Directives 96/73/EC and 2008/121/
EC of the European Parliament and of the Council and includes some different and/or additional fibre
denominations other than the present generic names (see F.3 and Table F.2).
The terms and definitions in this document are organized into principal elements:
— terms: generic name of the fibre (as 3.x), or, when relevant, specific names of the concerned fibre (as
3.x.y), with abbreviated terms (when existing);
— definitions: distinguishing attributes of the concerned fibre;
— in notes to entry, example of chemical formulae, other denominations (related to certain national or
regional legislations).
In some chemical formulae, k, m, n or p are used to express the repetition of the monomer or oligomer unit
and R for radical group.
The entries of Table D.1 in Annex D are an index of generic names in English and in French.
The entries of Table E.1 in Annex E are an index of abbreviated terms in alphabetical order with English and
French equivalents.
Annexes include the description of the fibre structures in case of fibre made of several components (see
Annex B) and the description of modified fibres (see Annex C).

DRAFT International Standard ISO/DIS 2076:2025(en)
Textiles — Man-made fibres — Generic names
1  Scope
This document defines the generic names used to designate the different categories of man-made fibres,
based on a main polymer, currently manufactured on an industrial scale for textile and other purposes,
together with the distinguishing attributes that characterize them. The term “man-made fibres” has been
adopted for those fibres obtained by a manufacturing process, as distinct from materials which occur
naturally in fibrous form.
This document gives recommendations of rules for the creation of the generic name (see Annex A).
NOTE These rules have been introduced in the sixth edition of ISO 2076, and thus, they are not applicable to the
existing generic names of the previous editions.
2  Normative references
There are no normative references in this document.
3  Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
