Textiles — Tests for colour fastness — Part X11: Colour fastness to hot pressing

Tests are given for hot pressing when the textile is dry, when it is wet, and when it is damp. The end-use of the textile usually determines which test should be made. A dry specimen (dry pressing) or a dry specimen covered with a wet cotton adjacent fabric (damp pressing) or a wet specimen covered with a wet cotton adjacent fabric (wet pressing) are pressed with a heating device at a specified temperature and pressure for a specified time.

Textiles — Essais de solidité des coloris — Partie X11: Solidité des coloris au pressage à chaud

1.1 La présente partie de l'ISO 105 prescrit une méthode pour la détermination de la résistance des teintures sur les textiles de toute nature, à tous leurs stades de transformation, au repassage ou au traitement industriel sur cylindres chauds. 1.2 Des essais sont prévus pour le repassage à chaud lorsque le textile est sec, lorsqu'il est mouillé et lorsqu'il est humide. La destination finale du textile détermine généralement quel essai doit être effectué.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for
coloured textiles and colorants.
This fifth edition cancels and replaces the fourth edition (ISO 105-X11:1994), which has been technically
revised.
The main changes are as follows:
— in subclause 7.1.1, the pressing temperatures have been changed to 120 °C, 160 °C and 210 °C, instead of
110 °C, 150 °C and 200 °C, in line with the ISO 3758:2023.
