ISO 2076-2021 pdf free download – Textiles — Man-made fibres — Generic names.
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” hasbeen adopted for those fibres obtained by a manufacturing process, as distinct from materials whichoccur 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 lS0 2076, and thus, they are not applicable tothe existing generic names of the previous editions.

3.1 man-made fibre
fibre obtained by a manufacturing process
Note 1 to entry: The term “man-made” fibre can be named “manufactured” fibre or “chemical” fibre.
4 General
4.1Table entries
The entries in Table 1 are organized into five principal elements: generic name, other denominations,abbreviated terms, distinguishing attributes and chemical formulae.
ln some chemical formulae, k, m, n or p are used to express the repetition of the monomer or oligomerunit 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 Englishand French equivalents.
4.2Generic name (for example, acetate)
This is the name to be used for the fibre whose attributes are described under the heading”Distinguishing attribute” in Table 1.The use of this name shall be limited to those fibres that contain not more than 15 % by mass of property-enhancing additives prior to spinning (no limit is placed uponthe proportion of additives that are not property enhanced). ln both the English and French languages,the generic name shall be written without capital letters.
The generic name may also apply to a man-made fibre which results from a manufacturing process thatcan confer a distinguishing attribute.
4.3Other denominations
When relevant, this is the denomination used for the fibre name in the regulation of some countries,which differs from the generic name.
The given denominations are relative to the following countries: China (identified as CN), countriesof the European Union (EU), Japan (JP) and the USA (US). For further information on the regulationrelated to these countries, see Annex F.
NOTE The country list can be extended in relation to the contribution of the concerned countries.
4.4Abbreviated terms (for example CA)
This is a two- to four-letter designation used to facilitate the naming of man-made fibres, for example insales and technical literature. ln some cases, the system of abbreviated terms given to textile fibres isdifferent from the one used for plastics.
NOTE The system of abbreviated terms for plastics is given in lSO 1043-1[2].
4.5Distinguishing attributes
These are attributes that differentiate one fibre from all the others.Chemical difference, which oftenresults in distinctive property differences, is the main basis for classification in this document; otherattributes are used, where necessary, to differentiate between otherwise similar man-made fibres.Thedistinguishing attributes are not necessarily those by which the fibres can be identified or the sameas those used for naming chemical molecules, nor are they necessarily suitable for the analysis of fibremixtures.ISO 2076 pdf download.
