Full title and description

ISO 105‑Z06:1998 — Textiles — Tests for colour fastness — Part Z06: Evaluation of dye and pigment migration. This International Standard specifies a laboratory method to evaluate the propensity of dyes and pigments (and optional migration inhibitors) in a pad‑bath to migrate under conditions representative of textile printing and dyeing processes.

Abstract

The standard defines a controlled test procedure to assess migration of colourants from a pad (pad‑bath) formulation onto adjacent materials or within a fabric structure. Migration is assessed visually and/or by instrumental measurement of reflectance; the method may be used to compare different dyes, pigments, inhibitors of migration, thickeners and electrolyte levels, and to investigate batches or baths where migration has been observed on production lines.

Scope

This part of ISO 105 specifies a method for evaluating the tendency of a pad‑bath containing dyes or pigments to produce migration during application. The procedure is applicable both for comparative laboratory studies (for example to compare dyes, pigments, migration inhibitors, thickeners or electrolyte concentrations) and for troubleshooting a dye or printing bath where migration has been observed in continuous production. Results are reported by visual grading or by measuring changes in reflectance.

Key topics and requirements

• Definition of test specimens and pad‑bath preparation (composition, concentration and any migration inhibitors).
• Specified application procedure that simulates pad application or conditions likely to produce migration.
• Controlled drying/setting and conditioning steps to reproduce typical processing conditions.
• Evaluation criteria: visual assessment scales and instrumental reflectance measurements for quantitative comparison.
• Reporting requirements (test conditions, bath composition, evaluation results and any deviations from the method).

Typical use and users

Used by textile test laboratories, dye and pigment manufacturers, textile printers, quality control departments in textile mills and contract printers, and standards committees when assessing formulations or investigating production migration problems. The method supports formulation development (e.g., selection of migration inhibitors or thickeners) and root‑cause analysis of migration defects on production lines.

Related standards

ISO 105‑Z06 is part of the ISO 105 series (Textiles — Tests for colour fastness) and complements other ISO 105 parts that describe specific colour‑fastness tests and procedures. National/adopted versions (for example UNE‑EN ISO 105‑Z06) exist where the ISO text has been adopted by regional standards bodies.

FAQ

Q: What is this standard?

A: ISO 105‑Z06:1998 is an ISO test method that specifies how to evaluate the tendency of dyes and pigments in a pad‑bath to migrate during application, using visual and/or instrumental assessments.

Q: What does it cover?

A: It covers preparation of the pad‑bath, test application to specimens, conditioning/drying, methods of evaluation (visual grading and reflectance measurement) and reporting of results for comparative and troubleshooting purposes.

Q: Who typically uses it?

A: Textile test laboratories, dye/pigment formulators, textile printers and mill quality control teams use this method for product development, quality assurance and investigation of migration problems.

Q: Is it current or superseded?

A: The ISO bibliographic record shows ISO 105‑Z06:1998 as published (Edition 1, 1998) and the entry has been subject to periodic review; ISO lists the publication as confirmed (i.e., the 1998 edition remains the current ISO document).

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series, which contains multiple parts covering different colour‑fastness test methods for textiles.

Q: What are the key keywords?

A: Dye migration; pigment migration; pad bath; colour fastness; textile testing; migration inhibitor; reflectance.
