Textiles - Test methods for nonwovens - Part 6: Absorption (ISO 9073-6:2000)
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.
Textilien - Prüfverfahren für Vliesstoffe - Teil 6: Absorption (ISO 9073-6:2000)
Dieser Teil der ISO 9073 beschreibt Verfahren zur Bewertung einiger Aspekte des Verhaltens von Vliesstoffen bei Anwesenheit von Flüssigkeiten. Im Einzelnen sind dies:
¾ die Dauer des Absorptionsvermögens von Flüssigkeiten;
¾ das Absorptionsvermögen von Flüssigkeiten;
¾ die Dochtwirkungsgeschwindigkeit von Flüssigkeiten (Kapillarwirkung).
Es sollte zur Kenntnis genommen werden, dass sich diese unterschiedlichen Aspekte des Absorptionsvermögens auf die verschiedensten Endanwendungen der geprüften Produkte beziehen können.
Die Prüfungen gelten nicht für Flächengebilde, die sehr stark absorbierende Materialien enthalten.
Textiles - Méthodes d'essai pour nontissés - Partie 6: Absorption (ISO 9073-6:2000)
La présente Norme internationale spécifie des méthodes permettant d'évaluer certains aspects du comportement
des nontissés en présence de liquides, et notamment:
_ le temps d'absorption du liquide;
_ le capacité d'absorption de liquide;
_ la vitesse d'imprégnation en liquide (capillarité).
Il convient de noter que ces différents aspects de l'absorption peuvent se rapporter à différents usages finaux des
produits testés.
Les essais ne s'appliquent pas aux étoffes renfermant des matériaux superabsorbants.

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.
ISO 9073 consists of the following parts, under the general title Textiles — Test methods for nonwovens:
� Part 1: Determination of mass per unit area
� Part 2: Determination of thickness
� Part 3: Determination of tensile strength and elongation
� Part 4: Determination of tear resistance
� Part 6: Absorption
� Part 7: Determination of bending length
� Part 8: Determination of liquid strike-through time (simulated urine)
� Part 9: Determination of drape coefficient
� Part 10: Linting (dry state)
� Part 11: Run-off tests
� Part 12: Demand absorbency

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
ISO 9073-6:2000(E)
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 the rings, these extra
lengths being distributed symmetrically in order to maintain the balance of the basket (see Figure1).
4.2.2 Container for liquid, of volume large enough to hold the submerged basket lying on its side.
4.2.3 Stopwatch.
4.2.4 Specified liquid, agreed-upon and specified and also identified in the test report.
4.3 Sampling
Carry out sampling in accordance with ISO 186.
4.4 Preparation and conditioning of test pieces
Cut five test pieces measuring (76� 1) mm in the machining direction and of sufficient length in the cross direction
so that they each weigh (5� 0,1) g. These strips shall be equally spaced across the fabric sample.
When there is a difference in the surface characteristics of the fabric, it may be necessary to duplicate the test
procedure so that each side of the fabric faces the internal surface of the basket.
Condition the test pieces in accordance with ISO 139.
The liquid shall be left long enough to equilibrate with the conditioning atmosphere.

4.5 Procedure
Carry out the test in the standard atmosphere for testing (see ISO 139)
a) Loosely roll a test piece starting from the short end and place it in the basket (4.2.1).
b) Drop the basket, on its side, from a height of (25� 1) mm from the liquid surface into the container (4.2.2) of
the specified liquid (4.2.4) and start the stopwatch (4.2.3).
c) Record the time taken for the basket to completely sink below the surface of the liquid.
Repeat with the other four test pieces.
Use fresh conditioned test liquid for each set of five test pieces.

4.6 Expression of results
Calculate the average liquid absorbency time, in seconds, and the standard deviation.
