Textiles - Tests for colour fastness - Part X11: Colour fastness to hot pressing (ISO/DIS 105-X11:2024)

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.

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.

Overview

prEN ISO 105‑X11 (ISO/DIS 105‑X11:2024) - Textiles - Tests for colour fastness - Part X11: Colour fastness to hot pressing - specifies laboratory methods to assess how textile colour withstands hot pressing (ironing and hot‑cylinder processing). Tests cover dry pressing, damp pressing and wet pressing, with the choice of test determined by the textile’s intended end‑use. The standard is part of the ISO 105 series on colour fastness and is intended for use in quality control, product development and conformity assessment.

Key topics and technical requirements

  • Test principle: A specimen (dry, damp or wet) is pressed between smooth heated plates under controlled temperature, pressure and time; staining of an adjacent cotton fabric and change in specimen colour are evaluated.
  • Pressing conditions:
    • Typical temperatures: 120 °C, 160 °C, 210 °C (±2 °C). Other temperatures may be used but must be reported.
    • Pressure: 4 kPa ± 1 kPa applied by the top plate.
    • Duration: specimens are held for 15 s at the specified temperature (per procedure details).
  • Specimens and sizes: fabric, yarn or compressed fibre formed into 40 mm × 100 mm specimens.
  • Adjacent and support materials:
    • Wool flannel padding (~260 g/m²) and a 3–6 mm heat‑resistant sheet.
    • Undyed cotton cloth (100–130 g/m²) and a cotton adjacent fabric (40 mm × 100 mm) for staining assessment.
  • Assessment: Colour change and staining are rated using the ISO grey scales (ISO 105‑A02 and ISO 105‑A03) immediately and after exposure to air, following ISO 105‑A01 procedures.
  • Special provisions:
    • Condition specimens per ISO 139 (65 % RH, 20 °C) when previously heat‑treated.
    • A household iron may be used if a laboratory heating device is unavailable, but accuracy and reproducibility are limited and must be reported.

Applications and users

Who uses ISO 105‑X11:

  • Textile and apparel manufacturers performing production quality checks.
  • Test laboratories and certification bodies verifying colour fastness to ironing and finishing processes.
  • R&D and finishing engineers evaluating dye stability during thermal processing (e.g., press‑finishing or hot‑cylinder calendering).
  • Buyers and compliance teams requiring harmonized test evidence for product specifications.

Practical use cases:

  • Selecting finishing parameters to avoid colour change during garment pressing.
  • Verifying that dyed fabrics won’t stain adjacent materials during industrial pressing or consumer ironing.
  • Comparing performance of dyes, pigments and fabric constructions under heat and moisture exposure.

Related standards

  • ISO 105‑A01 (general principles), ISO 105‑A02 (grey scale - change), ISO 105‑A03 (grey scale - staining), ISO 105‑F (standard adjacent fabrics), ISO 139 (conditioning), ISO 3758:2023 (ironing symbols/temperatures). These referenced standards support test execution and assessment.
