Full title and description

ISO 105‑C09:2001 — Textiles — Tests for colour fastness — Part C09: Colour fastness to domestic and commercial laundering — Oxidative bleach response using a non‑phosphate reference detergent incorporating a low temperature bleach activator. This part of ISO 105 specifies a laboratory method to determine consumer‑relevant shade change of textiles (excluding silk and wool) subjected to domestic/commercial laundering in which an oxygen bleach activator is used.

Abstract

The standard describes a test procedure that uses a non‑phosphate reference detergent (ECE type), sodium perborate tetrahydrate and the bleach activator TAED (tetra‑acetylethylenediamine) to simulate oxidative bleaching during laundering and to indicate shade change after multiple launderings. It notes exclusion of silk and wool, that the method is not intended for assessment of staining of adjacent fabrics (see ISO 105‑A04), and that optical brighteners present in some commercial products are not reflected by this test.

Scope

This standard specifies a controlled laboratory test to evaluate the oxidative‑bleach related shade change of textile materials when laundered using a non‑phosphate reference detergent together with a low‑temperature bleach activator. The method provides an indication of shade change behaviour after multiple launderings and is applicable to textiles of all kinds except silk and wool. It is not intended for assessment of dye staining of adjacent fabrics (for that see ISO 105‑A04) and does not account for effects due to optical brighteners in some commercial detergents.

Key topics and requirements

• Specifies test conditions that simulate domestic and commercial laundering with oxygen bleaching systems (use of ECE non‑phosphate reference detergent).
• Calls for sodium perborate tetrahydrate as the oxidising agent and TAED as the bleach activator in the primary procedure.
• Defines specimen preparation, washing cycle parameters, and evaluation of shade change (comparison against reference/grey scales or instrumental assessment as applicable to ISO 105 series guidance).
• Excludes silk and wool from applicability and excludes dye‑staining assessment of adjacent fabrics (points to ISO 105‑A04 for staining methods).
• Notes limitations: does not reflect contributions from optical brighteners and provides an indication of shade change rather than an exact prediction of every commercial product performance.

Key technical references and editorial changes (amendment and corrigendum) are recorded in ISO metadata.

Typical use and users

Used by textile test laboratories, quality control departments of textile and apparel manufacturers, dye and chemical suppliers, certification bodies and research institutions assessing colour fastness performance to bleaching in laundering. Also referenced by standards writers and procurement/specification authors when specifying colourfastness requirements for consumer and industrial textile products.

FAQ

Q: What is this standard?

A: ISO 105‑C09:2001 is an ISO standard that specifies a laboratory method to assess textile shade change caused by oxidative bleaching during domestic or commercial laundering using a non‑phosphate reference detergent and a low‑temperature bleach activator.

Q: What does it cover?

A: It covers the test procedure, reagents (reference detergent, sodium perborate tetrahydrate, TAED), washing conditions and evaluation approach for determining consumer‑relevant shade change after laundering. It excludes silk and wool and is not intended for evaluating staining of adjacent fabrics or effects of optical brighteners.

Q: Who typically uses it?

A: Textile testing laboratories, manufacturers’ quality/control teams, dye and chemical suppliers, standards developers and procurement/specification writers use this standard to evaluate and specify colourfastness to oxidative laundering.

Q: Is it current or superseded?

A: The 2001 edition (with its amendment published in 2003) remains the published edition listed by ISO; the document has been subject to ISO’s periodic review cycle and ISO metadata indicates revision activity and the development of a draft replacement (ISO/DIS 105‑C09). Users should check ISO or national standards bodies for the very latest status before relying on it for certification or regulatory requirements.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 family (Textiles — Tests for colour fastness), which contains multiple A, B, C, E, F and other parts covering general principles, fastness to light, washing, rubbing, staining, adjacent fabrics and reference materials.

Q: What are the key keywords?

A: Key keywords include colour fastness, oxidative bleach, laundering, TAED, sodium perborate, non‑phosphate reference detergent, ISO 105, shade change, textile testing.
