Nonwovens - Test methods - Part 6: Absorption (ISO 9073-6:2025)
This document specifies methods for the evaluation of some aspects of the behaviour of nonwoven fabrics in the presence of liquids. In particular:
— the liquid absorbency time;
— the liquid absorptive capacity;
— the liquid wicking rate (capillarity).
The different aspects of absorbency can relate to various end uses of the tested products.
The tests do not apply to any fabric containing super absorbent materials.
Vliesstoffe - Prüfverfahren - Teil 6: Absorption (ISO 9073-6:2025)
Dieses Dokument beschreibt Verfahren zur Bewertung einiger Aspekte des Verhaltens von Vliesstoffen, wenn sie Flüssigkeiten ausgesetzt sind. Im Einzelnen sind dies:
die Dauer der Absorption von Flüssigkeiten;
die Absorption von Flüssigkeiten;
die Dochtwirkungsgeschwindigkeit von Flüssigkeiten (Kapillarwirkung).
Die unterschiedlichen Aspekte der Absorption können sich auf die verschiedensten Endanwendungen der geprüften Produkte beziehen.
Die Prüfungen gelten nicht für Flächengebilde, die sehr stark absorbierende Materialien enthalten.

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 3.
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 part of ISO 9073 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 9073-6 was prepared by Technical Committee ISO/TC 38, Textiles.

SAFETY WARNING — This standard does not claim to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability of regulatory limitations prior to use. It is
expected that the person performing this test has been fully trained in all aspects of this procedure.
1 Scope
This part of ISO 9073 describes methods for the evaluation of some aspects of the behaviour of nonwoven
fabrics in the presence of liquids. In particular:
— the liquid absorbency time;
— the liquid absorptive capacity;
— the liquid wicking rate (capillarity).
It should be noted that these different aspects of absorbency may relate to various end uses of the tested
products.
The tests are not applicable to any fabric containing super absorbent materials.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute
provisions of this part of ISO 9073. For dated references, subsequent amendments to, or revisions of, any
of these publications do not apply. However, parties to agreements based on this part of ISO 9073 are
encouraged to investigate the possibility of applying the most recent editions of the normative documents
indicated below. For undated references, the latest edition of the normative document referred to applies.
Members of ISO and IEC maintain registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this part of ISO 9073, the following terms and definitions apply.
3.1
liquid absorbency time
time required for a sample of absorbent material to become completely wetted by the test liquid, i.e. to
imbibe a liquid into its interior structure under specified conditions
oSIST prEN ISO 9073-6:2024
ISO/DIS 9073-6:2024(en)
3.2
liquid absorptive capacity
LAC
mass of liquid that is absorbed by unit mass of the test absorbent expressed as a percentage of the mass of
the test absorbent, under specified conditions and after a specified time
3.3
liquid wicking rate
measure of the capillarity of the test material, i.e. the rate at which the liquid is transported into the fabric
by capillary action
4 Liquid absorbency time
4.1 Principle
The liquid absorbency time test measures the time required for the complete wetting of a specimen strip
loosely rolled into a cylindrical wire basket and dropped on to the surface of the liquid from a height of 25 mm.
In this method the liquid can come into contact with all surfaces of the sample.
4.2 Apparatus
4.2.1 Cylindrical wire basket, open at one end, with height (80 ± 1) mm and diameter (50 ± 1) mm,
and constructed of suitable gauge wire to obtain a mass of (3 ± 0,1) g, e.g. 0,5 mm diameter stainless steel
wire. The mesh shall have openings approximately 20 mm square and be soldered in order to create a firm
structure. Extra solder may be added to adjust the mass or the mass may be adjusted by partially doubling
