Textiles - Tests for colour fastness - Part Z06: Evaluation of dye and pigment migration (ISO 105-Z06:1998)

This standard specifies a method for determining the migration of dyestuffs.

Textilien - Farbechtheitsprüfungen - Teil Z06: Bewertung der Migration von Farbstoffen und Pigmenten (ISO 105-Z06:1998)

Dieser Teil der ISO 105 beschreibt ein Verfahren zur Bestimmung der Migrationsneigung eines Klotzfolttenansatzes, der Farbstoffe oder Pigmente, im folgenden als Farbmittel bezeichnet, enthält und der auch unterschiedliche Mengen und Arten von Antimigrationsmitteln enthalten kann. Das Ausmaß der Migration wird durch visuelle Prüfung oder durch Reflexionsmessungen bestimmt. Das Prüfverfahren kann zum Vergleich der Migrationsneigung von Farbstoffen und der Wirksamkeit unterschiedlicher Antimigrationsmittel, Verdickungsmittel und Elektrolyte auf die Migration herangezogen werden. Das Verfahren kann auch zur Beurteilung einer Klotzflotte dienen, bei deren Verwendung auf einer Kontinueanlage, Migration festgestellt worden war.

Textiles - Essais de solidité des teintures - Partie Z06: Evaluation de la migration des teintures et pigments (ISO 105- Z06:1998)

La présente partie de l'ISO 105 décrit une méthode pour l'évaluation de la propension à la migration d'un bain de foulardage contenant des colorants ou des pigments (appelés dans la suite du texte "colorants") mais aussi, éventuellement, des inhibiteurs de migration de types différents et en quantité variable. Le degré de migrafion peut être évalué par examen visuel ou par mesure du facteur de réflexion. La méthode d'essai peut être utilisée pour comparer la propension à la migration des teintures, ainsi que l'effet sur cette migration de différents types d'inhibiteurs de migration, d'agents épaississants et d'électrolytes. Elle peut également servir à évaluer un bain de teinture pour lequel on a observé une migration sur une chaîne de teinture en continu.

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.
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.
International Standard ISO 105-Z06 was prepared by Technical Committee
ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and
colorants.
ISO 105 was previously published in thirteen “parts”, each designated by a
letter (e.g. “Part A»), with publication dates between 1978 and 1985. Each
part contained a series of “sections”, each designated by the respective
part letter and by a two-digit serial number (e.g. “Section A01)”). These
sections are now being republished as separate documents, themselves
designated “parts” but retaining their earlier alphanumeric designations. A
complete list of these parts is given in ISO 105-A01.
Annex A of this part of ISO 105 is for information only.

INTERNATIONAL STANDARD  ISO ISO 105-Z06:1998(E)
Textiles — Tests for colour fastness —
Part Z06:
Evaluation of dye and pigment migration
1 Scope
This part of ISO 105 describes a method for assessing the migration propensity of a pad liquor system containing
dyes or pigments, subsequently referred to as colorants, and which may also contain different types and amounts
of migration inhibitors. The degree of migration is obtained by visual examination or by reflectance
measurements.
The test method may be used to compare the migration propensity of dyes and the effect on migration of different
types of migration inhibitors, thickeners and electrolyte. The method may also be used to evaluate a pad liquor
with which migration has been found on a continuous dye range.
2 Normative reference
The following standard contains provisions which, through reference in this text, constitutes provisions of this
part of ISO 105. At the time of publication, the edition indicated was valid. All standards are subject to revision
and parties to agreements based on this part of ISO 105 are encouraged to investigate the possibility of applying
the most recent edition of the standard listed below. Members of IEC and ISO maintain registers of currently
valid International Standards.
ISO 105-A02: 1993, Textiles - Tests for colour fastness - Part A02 Grey scale for assessing change in colour.
3 Definitions
For the purposes of this part of ISO 105, the following definitions apply.
Colorant applied to or formed on a substrate, via the molecularly dispersed state, which exhibits some
3.1  dye:
degree of permanence.
3.2  migration: Movement of a chemical, dye or pigment between fibres, within a substrate or between substrates
due to capillary forces.
NOTE —  Migration may occur in textile processing, testing, storage and use.
3.3  pigment: Colorant in particulate form which is insoluble in a substrate, but which can be dispersed in the
substrate to modify its colour.
3.4  pad: Impregnation of a substrate (usually fabric) with a liquor, followed by squeezing between rollers.

4 Principle
Fabric impregnated with test colorant alone, or with test colorant and migration inhibitor, is dried while partially
covered with a watch glass, permitting differential drying and therefore, migration to occur. The degree of
migration is evaluated by visual examination or by reflectance measurements of the covered and uncovered areas.
NOTES
1  When drying conditions are not constant and/or uniform, uneven migration may occur, causing shade variations during a
run, or shade differences between the face and back, or between the side and centre of the fabric.
2  The pad liquor composition may be modified by varying the amount or type of migration inhibitor and tested in the
laboratory prior to the application on the range. The colorant concentration, the fabric and the wet pickup should be the
same in the laboratory as used on the range. It is then possible to correlate the test results with the improvement experienced
in practice.
Two procedures are described:
Procedure A. The fabric assembly is allowed to dry at room temperature. The procedure is very simple, but time-
consuming (overnight).
Procedure B. The fabric assembly is dried in a laboratory dryer or oven, either with, or without air circulation.
This procedure is faster but somewhat more complicated than procedure A.
5 Apparatus and materials
5.1 Fabric pieces for dyeing.
NOTE —  For disperse dyes, vat dyes and pigments, generally the preferred fabric is a blend of 65 %:35 % (m/m) polyester:
cotton gabardine or heavy twill, heat set, bleached and mercerized. For soluble dyes with affinity to cellulose (e.g. reactive
dyes), the preferred fabric is a bleached and mercerized 100 % cotton gabardine or heavy twill. Howev
