Full title and description

ISO 105‑X07:1994 — Textiles — Tests for colour fastness — Part X07: Colour fastness to cross‑dyeing: Wool. Specifies a laboratory method to determine the resistance of textile colours (particularly wool) to the action of processes used for dyeing wool, by exposing test specimens in contact with adjacent fabrics to wool dye‑baths (without dyestuff) and assessing change and staining with the grey scales.

Abstract

This part of ISO 105 defines a controlled test procedure to evaluate the tendency of wool and wool‑containing textiles to change colour or to stain adjacent fabrics when subjected to typical wool dyeing processes. Specimens are placed in contact with specified adjacent fabrics and treated in representative wool dye‑baths (without added dyestuff). After rinsing and drying, the specimen’s change in colour and staining of adjacent fabrics are evaluated visually using the ISO grey scales.

Scope

ISO 105‑X07:1994 applies to wool and wool‑containing textile materials and specifies a laboratory method to assess their colour fastness when subjected to dyeing processes used for wool (cross‑dyeing conditions). The procedure evaluates both change in the specimen’s own colour and staining transferred to adjacent fabrics. The method is intended for use in quality control, comparative testing and where assessing the compatibility of textile substrates and finishes with wool dyeing cycles is required.

Key topics and requirements

• Test principle: specimen and adjacent fabrics are exposed in contact to representative wool dye‑baths without added dyestuff to simulate process conditions.
• Sample preparation: dimensions, conditioning and selection of adjacent fabrics appropriate to the test.
• Bath and exposure conditions: description of typical wool dye‑bath types and the controlled temperature/time/agitation parameters used.
• Rinsing and drying: standardized post‑treatment procedures prior to assessment.
• Assessment criteria: visual evaluation of change in colour and staining using ISO grey scales (change and staining scales).
• Reporting: required test conditions, specimen identification, adjacent fabric specification and resulting grey‑scale grades.

Typical use and users

Used by textile testing laboratories, dye houses, fabric and garment manufacturers, quality control departments, standards and conformity assessment bodies, and product R&D teams. Typical applications include QC checks on wool dyeing processes, compatibility testing for blends and finishes, supplier verification and troubleshooting of staining or migration problems during industrial dyeing.

Related standards

ISO 105 is a multi‑part family. Key related parts include ISO 105‑A01 (general principles and guidance), ISO 105‑A02 / A03 (grey scales for assessing change and staining), ISO 105‑C06 (colour fastness to domestic and commercial laundering), ISO 105‑X12 (colour fastness to rubbing) and the F‑series (specifications for adjacent fabrics). Users should consult ISO 105‑A01 and the appropriate adjacent‑fabric specifications when applying ISO 105‑X07.

FAQ

Q: What is this standard?

A: ISO 105‑X07:1994 is a short ISO test method that defines how to evaluate the colour fastness of wool and wool‑containing textiles to processes used for dyeing wool, focusing on both change in colour and staining of adjacent fabrics.

Q: What does it cover?

A: It covers specimen preparation, exposure of specimens (in contact with adjacent fabrics) to representative wool dye‑baths without dyestuff, post‑treatment rinsing/drying and visual assessment using ISO grey scales to rate colour change and staining.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers of wool fabrics and garments, dye houses, quality assurance teams, and R&D or product development groups concerned with dyeing behaviour and staining risks.

Q: Is it current or superseded?

A: The 1994 fourth edition replaced the 1987 edition. The 1994 edition was reviewed and confirmed at a systematic review (confirmed in 2020), and is treated as the current edition unless superseded by a later formal revision.

Q: Is it part of a series?

A: Yes — ISO 105 is a comprehensive multi‑part series on tests for colour fastness. Part X07 is one element in the X (miscellaneous) group of colour‑fastness tests and works alongside A‑series guidance (grey scales and general principles), C‑series laundering tests and other X‑ and F‑parts that specify adjacent fabrics and related procedures.

Q: What are the key keywords?

A: colour fastness, cross‑dyeing, wool, staining, adjacent fabric, grey scale, textile testing.
