Full title and description

ISO 105‑E13:1994 — Textiles — Tests for colour fastness — Part E13: Colour fastness to acid‑felting: Severe. This part of ISO 105 specifies a laboratory method for assessing the resistance of textile dyes to acid‑felting under severe conditions by milling specimens in acidic solutions and assessing colour change and staining with grey scales.

Abstract

A specimen of the textile, in contact with adjacent fabrics, is milled in solutions of acetic and/or sulfuric acid, then rinsed and dried. The change in colour of the specimen and the staining of adjacent fabrics are assessed using grey scales to give an objective evaluation of dye fastness to acid‑felting under severe conditions.

Scope

This part of ISO 105 specifies a test method to determine the resistance of dyes on textiles, at all stages of manufacture, to the action of acids used in severe acid‑felting (milling) conditions. It applies to textiles in all kinds and in all forms and covers the procedure of milling in acetic and/or sulfuric acid solutions followed by assessment of colour change and staining on adjacent fabrics using grey scales.

Key topics and requirements

• Purpose: evaluate dye fastness of textiles to acid‑felting (severe conditions).
• Specimen preparation: textiles in their various forms and stages of manufacture.
• Reagents: use of acetic and/or sulfuric acid solutions at prescribed concentrations.
• Procedure: milling (felting) of specimen in contact with adjacent fabrics, rinsing and drying.
• Assessment: change in colour of the specimen and staining of adjacent fabrics judged with grey scales.
• Reporting: record test conditions, reagents, specimen description and grey scale ratings.

Typical use and users

Used by textile manufacturers, dye and finishing houses, independent textile testing laboratories, quality assurance teams and standards bodies to verify performance of dyeing and finishing processes where acid‑felting resistance is required (for example wool products subjected to acidic felting processes).

FAQ

Q: What is this standard?

A: ISO 105‑E13:1994 is an international standard that specifies a laboratory method to assess the colour fastness of textile dyes to severe acid‑felting (milling) conditions.

Q: What does it cover?

A: It covers the test procedure of milling textile specimens in acetic and/or sulfuric acid solutions while in contact with adjacent fabrics, followed by rinsing, drying and assessment of colour change and staining using grey scales.

Q: Who typically uses it?

A: Textile producers, dyeing and finishing operations, independent testing laboratories, product QA teams and standards organizations use this method to verify resistance to acid‑felting and to support product specifications and compliance checks.

Q: Is it current or superseded?

A: The 1994 third edition remains the published edition; the document was most recently reviewed and confirmed (status maintained) and a technical corrigendum (ISO 105‑E13:1994/Cor 1:1999) exists to correct minor items. Users should verify national/adopted versions if required for regulatory or procurement purposes.

Q: Is it part of a series?

A: Yes — ISO 105 is a multi‑part series covering tests for colour fastness with numerous parts (E, A, X, etc.) that address specific agents and conditions; ISO 105‑E13 is the part addressing severe acid‑felting conditions.

Q: What are the key keywords?

A: Colour fastness; acid‑felting; acid milling; acetic acid; sulphuric acid; grey scale; textile testing; ISO 105.
