Textiles - Quantitative chemical analysis - Part 22: Mixtures of viscose or certain types of cupro or modal or lyocell and flax fibres (method using formic acid and zinc chloride) (ISO 1833-22:2013)

This part of ISO 1833 is applicable, after removal of non-fibrous matter, to binary mixtures of - viscose or certain types of the current cupro or modal or lyocell fibres with - flax fibres. If a cupro or modal fibre is found to be present, a preliminary test should be carried out to see whether it is soluble in the reagent. The part of ISO 1833 is not applicable to mixtures in which the flax fibre has suffered extensive chemical degradation, nor when the viscose, cupro, modal or lyocell fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely.

Textilien - Quantitative chemische Analysen - Teil 22: Mischungen aus Viskose oder bestimmten Arten von Cupro-, Modal- oder Lyocellfasern und Flachsfasern (Ameisensäure-/Zinkchlorid-Verfahren) (ISO 1833-22:2013)

Das vorliegende Verfahren ist nach dem Abtrennen der nichtfaserigen Begleitstoffe auf binäre Fasermischungen
aus
- Viskose oder aus den gebräuchlichsten Cupro-, Modal- oder Lyocellfasern
und
- Flachsfasern
anwendbar.
Bei Vorhandensein einer Cupro- oder Modalfaser sollte eine Vorprüfung durchgeführt werden, um
festzustellen, ob diese in dem Reagenz löslich ist.
Das Verfahren gilt weder für Fasermischungen, bei denen sich die Flachsfasern hochgradig chemisch
abgebaut haben, noch wenn sich die Viskose-, Cupro- oder Modalfaser bei Vorhandensein bestimmter
dauerhafter Ausrüstungen oder nicht vollständig abtrennbarer Reaktivfarbstoffe als nicht vollständig löslich
erweist.
Der vorliegende Teil von ISO 1833 erfordert die Anwendung von Substanzen/Verfahren, die für die
Gesundheit und die Umwelt schädlich sein können, wenn die entsprechenden Bedingungen nicht
eingehalten werden. Es wird lediglich auf die technische Eignung Bezug genommen, und der
Anwender wird von den rechtlichen Verpflichtungen in Bezug auf Gesundheit, Sicherheit und Umwelt
in keiner Weise entbunden.

Textiles - Analyse chimique quantitative - Partie 22: Mélanges de viscose ou de certains types de cupro, modal ou lyocell et de fibres de lin (méthode à l'acide formique et au chlorure de zinc) (ISO 1833-22:2013)

L'ISO 1833-22:2013 s'applique, après élimination des matières non fibreuses, aux textiles composés de mélanges binaires de viscose ou certains types de fibres de cupro, de modal ou de lyocell actuelles avec des fibres de lin.
Si la présence de fibres de cupro ou de modal est constatée, il convient de procéder à un essai préliminaire pour déterminer si elles sont solubles dans le réactif.
L'ISO 1833-22:2013 ne s'applique pas aux mélanges dans lesquels les fibres de lin ont subi une dégradation chimique importante, ni lorsque les fibres de viscose, de cupro, de modal ou de lyocell sont devenues incomplètement solubles par la présence de certains produits d'apprêts permanents ou de colorants réactifs qui ne peuvent être totalement éliminés.

Tekstilije - Kvantitativna kemična analiza - 22. del: Mešanice viskoznih ali določenih vrst bakrenih ali modalnih ali liocelnih in ploščatih vlaken (metoda z uporabo mravljične kisline in cinkovega klorida) (ISO 1833-22:2013)

Ta del standarda ISO 1833 je po odstranitvi nevlakenske snovi uporaben za dvokomponentne mešanice viskoznih ali določenih vrst običajnih bakrenih ali modalnih ali liocelnih vlaken z lanenimi vlakni. Če je ugotovljena prisotnost bakrovih ali modalnih vlaken, je treba predhodno preskusiti, ali so topna v reagentu za raztapljanje. Del standarda ISO 1833 ni uporaben za mešanice, ki vsebujejo kemično znatno razgrajeno laneno vlakno, in tudi ne, če se izkaže, da viskozna, bakrena, modalna ali liocelna vlakna niso popolnoma topna zaradi prisotnih permanentnih apretur ali reaktivnih barvil, ki jih ni mogoče popolnoma odstraniti.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
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.
ISO 1833-22 was prepared by Technical Committee ISO/TC 38, Textiles.
ISO 1833 consists of the following parts, under the general title Textiles — Quantitative chemical analysis:
— Part 1: General principles of testing
— Part 2: Ternary fibre mixtures
— Part 3: Mixtures of acetate and certain other fibres (method using acetone)
— Part 4: Mixtures of certain protein and certain other fibres (method using hypochlorite)
— Part 5: Mixtures of viscose, cupro or modal and cotton fibres (method using sodium zincate)
— Part 6: Mixtures of viscose or certain types of cupro or modal or lyocell and cotton fibres (method using
formic acid and zinc chloride)

other fibres (method using dimethylformamide)

— Part 14: Mixtures of acetate and certain chlorofibres (method using acetic acid)
— Part 15: Mixtures of jute and certain animal fibres (method by determining nitrogen content)

Textiles — Quantitative chemical analysis —
Part 22:
Mixtures of viscose or certain types of cupro or modal or lyocell
and flax fibres (method using formic acid and zinc chloride)
1 Scope
This method is applicable, after removal of non-fibrous matter, to binary mixtures of
 viscose or most of the current cupro or modal or lyocell fibres
with
 flax fibres.
If a cupro or modal fibre is found to be present, a preliminary test should be carried out to see whether it is
soluble in the reagent.
The method is not applicable to mixtures in which the flax fibres has suffered extensive chemical degradation,
nor when the viscose, cupro or modal fibre is rendered incompletely soluble by the presence of certain
permanent finishes or reactive dyes that cannot be removed completely.
This part of ISO 1833 calls for 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.
