Full title and description

ISO 105‑X11:1994 — Textiles — Tests for colour fastness — Part X11: Colour fastness to hot pressing (often referenced as colour fastness to ironing). The standard specifies a laboratory method for assessing the resistance of textile colour to the action of hot pressing (dry, damp or wet conditions) using a heated platen or ironing device under controlled temperature, pressure and time.

Abstract

This part of ISO 105 gives procedures for hot pressing textile specimens in three conditions: dry pressing (dry specimen), damp pressing (dry specimen covered with a wet cotton adjacent fabric) and wet pressing (wet specimen covered with a wet cotton adjacent fabric). After exposure to a prescribed temperature, pressure and time, colour change and staining on adjacent fabrics are assessed (typically using a greyscale and standard adjacent fabrics). The test is intended to reproduce the effects of ironing or hot-roll finishing on the colour of textile materials.

Scope

Specifies a laboratory test method to determine the colour fastness of textiles to hot pressing (ironing) and similar thermal/mechanical treatments. The scope covers the selection of test specimens and adjacent fabrics, required equipment (heated platen/ironing device), prescribed temperatures, pressure and dwell times, and evaluation procedures for colour change and staining. It applies to textiles of all types and in all states of manufacture where hot pressing or ironing is part of the intended end‑use or finishing.

Key topics and requirements

• Test modes: dry pressing, damp pressing (dry specimen + wet adjacent cotton), and wet pressing (wet specimen + wet adjacent cotton).
• Controlled equipment: heated parallel plates or ironing device capable of maintaining specified temperature and exerting defined pressure for the set time interval.
• Specimen preparation: size, conditioning, and use of specified adjacent fabric(s) (e.g., cotton) to detect staining.
• Specified test parameters: temperature, pressure (typically reported in kPa), and dwell time appropriate to the test mode and material.
• Assessment: visual evaluation of colour change and staining using grey scales and reference adjacent fabrics; reporting of results and any observed physical damage (shading, shine, marking).
• Reporting requirements: details of test conditions, apparatus, specimen descriptions and evaluation results to ensure reproducibility.

Typical use and users

Used by textile manufacturers, dye houses, finishing mills, independent textile testing laboratories, quality control departments and product compliance teams to assess how fabrics and garments withstand hot pressing or ironing during manufacturing or consumer use. Also referenced by standards writers and national bodies when adopting or harmonizing test methods for care labelling and performance specifications.

Related standards

ISO 105 is a multipart series covering many colour fastness tests; commonly referenced related parts include ISO 105‑E01 (colour fastness to water), ISO 105‑E04 (colour fastness to perspiration), ISO 105‑X12 (colour fastness to crocking), and other ISO 105 X/E/F parts that address specific agents and conditions. National/adopted versions (for example EN ISO 105‑X11 / ÖNORM EN ISO 105‑X11) exist for regional use.

FAQ

Q: What is this standard?

A: ISO 105‑X11:1994 is a standardized test method within the ISO 105 series that specifies how to determine the colour fastness of textile materials when exposed to hot pressing / ironing conditions.

Q: What does it cover?

A: It covers procedures for dry, damp and wet hot‑pressing tests using a heated platen or ironing device, including specimen preparation, test conditions (temperature, pressure, time), adjacent fabrics, and visual assessment of colour change and staining.

Q: Who typically uses it?

A: Textile and apparel manufacturers, finishing and dyeing operations, independent test laboratories, quality assurance teams and standards bodies use the method to verify product performance and to support care labelling or product specifications.

Q: Is it current or superseded?

A: The 1994 edition (Edition 4) is the published version listed by ISO. ISO records show the standard was reviewed and confirmed in past systematic reviews and that the document has been placed in a revision stage (ISO has indicated development of a draft ISO/DIS 105‑X11). Users should check with their national body or the ISO catalogue for the very latest status or any newer edition before relying on the test for regulatory or contractual purposes.

Q: Is it part of a series?

A: Yes — ISO 105 is a multipart series of standards covering many different colour‑fastness tests (parts A, C, E, F, X, etc.). Part X11 specifically addresses hot pressing; other parts address laundering, perspiration, light, rubbing and many other agents.

Q: What are the key keywords?

A: Colour fastness, hot pressing, ironing, textiles, ISO 105, test method, adjacent fabric, grey scale, temperature, pressure.
