Textiles and textile products - Microplastics from textile sources - Part 1: Determination of material loss from fabrics during washing (ISO 4484-1:2023)

The method provides a means of systematically evaluating fibre loss during washing. Consideration has been given to best representation of realistic laundry conditions, to achieve comparable and accurate results. The method is designed to assess both synthetic and natural fiber loss.

Textilien und textile Erzeugnisse - Mikroplastik aus textilen Quellen - Teil 1: Bestimmung des Materialverlusts von textilen Flächengebilden beim Waschen (ISO 4484-1:2023)

Dieses Dokument beschreibt ein Verfahren zur systematischen Erfassung des Faserverlusts von Textilien unter Prüfbedingungen beim Waschen, um vergleichbare und genaue Ergebnisse zu erzielen. Es gibt keinen direkten Zusammenhang zwischen Materialverlusten bei der Haushaltswäsche und der gewerblichen Wäsche. Das Verfahren wurde entwickelt, um sowohl Faserverluste aller Arten zu bewerten, und stellt eine Modifikation von ISO 105 C06 dar.
ANMERKUNG   In diesem Dokument wird davon ausgegangen, dass es sich bei den gesammelten Rückständen um Faserfragmente handelt. Zur Ermittlung der Art/Zusammensetzung dieser Rückstände kann das in ISO 4484 2 beschriebene Verfahren angewendet werden.

Textiles et produits textiles - Microplastiques d'origines textiles - Partie 1: Détermination des pertes de matière des étoffes pendant le lavage (ISO 4484-1:2023)

La méthode fournit un moyen de recueillir de manière systématique les pertes de matière des étoffes
dans des conditions de lavage normalisées afin d’obtenir des résultats exacts et comparables.
La méthode est conçue pour évaluer les pertes de matière synthétique et naturelle et constitue une
modification de l’ISO 105-C06.
NOTE Dans le cadre du présent document, tout débris recueilli est présumé être un fragment de fibre. Pour une
meilleure compréhension de la composition d’un tel débris, veuillez consulter le prISO 4484-2.

Tekstilije in tekstilni izdelki - Mikroplastika iz tekstilnih virov - 1. del: Ugotavljanje izgube materiala iz tkanin med pranjem (ISO 4484-1:2023)

Metoda omogoča sistematično ocenjevanje izgub vlaken med pranjem. Pripraviti je treba čim boljši prikaz realnih pogojev pranja, da se dosežejo primerljivi in natančni rezultati. Metoda je zasnovana za ocenjevanje izgub sintetičnih in naravnih vlaken.

Introduction
There is significant evidence that during laundering of textiles, release of fragments can occur. The
purpose of this document is to provide a method of assessment, to be used in laboratories, of the degree
to which different fabrics shed fibres and fibre fragments of all types. The results obtained by using
this document should enable manufacturers of textile articles to make an informed choice about the
type of fabric to use to reduce/minimize shedding as well as to test different methods of manufacture
that minimize material loss during laundering.

Part 1:
Determination of material loss from fabrics during
washing
1 Scope
This document describes a method for systematically collecting material loss from fabrics under
laundering test conditions to achieve comparable and accurate results. There is no direct correlation to
material loss during domestic and commercial laundering. The method is designed to assess material
loss of all types.
NOTE In this document, any collected debris is assumed to be fibre fragments. For the identification of the
nature/composition of this debris, the method described in ISO 4484-2 can be used.
2 Normative references

undated references, the latest edition of the referenced document (including any amendments) applies.

4 Principle
The test specimen is subjected to an accelerated laundering process under conditions of temperature,
time, and mechanical action. The resultant wash liquor is vacuum filtered. Material loss is assessed
gravimetrically to approximate material loss during simulated domestic laundering. The ratio of the
mass of the material loss by the test specimen mass is then reported.
Note Consideration on detergent can be found in A.1.

Introduction
There is significant evidence that during laundering of textiles, material loss and fragmentation can
occur. These fibre fragments find their way through drainage systems into water courses and oceans,
whereupon it is suggested that they are ingested by aquatic life (fish, shellfish, etc.). The purpose of
this document is to provide a method of assessment, to be used in laboratories, of the degree to which
different fabrics shed fibres and fibre fragments of both synthetic and natural origin. The results
obtained by using this standard will enable manufacturers of textile articles to make an informed
choice about the type of fabric to use to reduce/minimize shedding as well as to test different methods
of manufacture that minimize material loss during use/laundering.
