Full title and description

ISO 105‑X14:1994 — Textiles — Tests for colour fastness — Part X14: Colour fastness to acid chlorination of wool: Sodium dichloroisocyanurate. This part of ISO 105 specifies a laboratory method using sodium dichloroisocyanurate to simulate mildly acidic chlorination processes used in wool textile manufacture and to assess resulting changes in colour.

Abstract

A specimen of wool (in any form) is treated in a formic‑acid buffer to which sodium dichloroisocyanurate and sodium hydrogen sulfite solutions are added successively; the specimen is then rinsed, dried and the change in colour assessed using the grey scale. The test simulates manufacturing operations in which liquids containing or liberating active chlorine under mildly acidic conditions are used (for example to impart shrink‑resistant properties).

Scope

This part of ISO 105 defines a controlled laboratory procedure for determining the resistance of dyes on wool (all forms) to acid chlorination using sodium dichloroisocyanurate. The method is intended to reproduce the effect on colour when wool is exposed during processing to liquids that contain or evolve active chlorine under mildly acidic conditions (for instance during shrink‑resist treatments). The procedure specifies reagents, treatment sequence (formic acid buffer, sodium dichloroisocyanurate, sodium hydrogen sulfite), rinsing and drying, and assessment using the grey scale.

Key topics and requirements

• Applicability: wool textiles in all forms (yarns, fabrics, finished garments) for determination of colour change after acid chlorination.
• Reagents and materials: formic acid buffer, sodium dichloroisocyanurate (source of active chlorine), sodium hydrogen sulfite, distilled water and grey scale for assessment.
• Procedure steps: controlled exposure in buffer, sequential addition of oxidizing and reducing reagents, standardized rinsing and drying.
• Assessment method: visual comparison of treated specimen against untreated reference using the grey scale for change in colour and staining.
• Safety and handling: use of oxidizing chlorine‑releasing chemicals requires appropriate lab safety controls, ventilation and waste management (chemical safety is expected but not detailed beyond normal laboratory practice in the standard).
• Purpose: simulate manufacturing chlorination to evaluate colour fastness and to support quality control and process development for shrink‑resistant finishes.

Typical use and users

Used by textile and dyeing laboratories, quality control teams in wool textile manufacturing, test houses, certifiers and researchers working on dye fastness or shrink‑resist finishing processes. The standard is primarily a laboratory test method for product evaluation, process troubleshooting and comparative testing of treatments and dyes.

Related standards

ISO 105‑X14 is one part of the ISO 105 series (Tests for colour fastness). Related parts include other X‑series items that address wool and chemical processes (for example ISO 105‑X13 and other ISO 105 parts covering different aggressive treatments and assessments). The 1987 edition of ISO 105‑X14 was withdrawn and superseded by ISO 105‑X14:1994; some national or regional adoptions (for example UNE‑EN ISO 105‑X14) exist where the ISO method was incorporated into national standards.

FAQ

Q: What is this standard?

A: ISO 105‑X14:1994 is an ISO test method that specifies how to assess the colour fastness of wool to acid chlorination using sodium dichloroisocyanurate; it is one part of the ISO 105 series covering tests for colour fastness.

Q: What does it cover?

A: It covers the reagents, controlled treatment procedure, rinsing and drying, and the assessment of colour change using the grey scale after exposing wool specimens to an acid chlorination simulation. The aim is to reproduce effects from manufacturing treatments that involve active chlorine under mildly acidic conditions.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers of wool products, quality control and R&D teams, test houses and certification bodies use this method to evaluate dye performance and the impact of chlorination‑type processes on colour.

Q: Is it current or superseded?

A: The 1994 edition (Edition 3) replaced the 1987 edition; ISO’s record shows ISO 105‑X14:1994 as published in September 1994 and that the document was reviewed and confirmed (most recently in ISO’s 2020 review cycle), so the 1994 edition remains the current published ISO text unless a later revision is issued.

Q: Is it part of a series?

A: Yes — ISO 105 is a multi‑part series of standards covering tests for colour fastness; X14 is the part addressing acid chlorination of wool and it is published alongside many other parts addressing different agents and processes affecting colour fastness.

Q: What are the key keywords?

A: Acid chlorination, sodium dichloroisocyanurate, wool, colour fastness, grey scale, ISO 105, textile testing, shrink‑resistance.
