Full title and description

ISO 105‑E14:1994 — Textiles — Tests for colour fastness — Part E14: Colour fastness to acid‑felting: Mild. Method for assessing the change in colour of textile specimens and staining of adjacent fabrics produced by the action of dilute, hot mineral acids under mild milling (felting) conditions.

Abstract

This part of ISO 105 specifies a laboratory procedure for determining the resistance of dyes on textiles to dilute hot mineral acids under mild acid‑felting (milling) conditions. A specimen in contact with adjacent fabrics is milled in an acid solution, rinsed and dried; change in colour and staining are assessed using grey scales.

• Number of pages: 2.

Scope

Sets out a standardized test method for evaluating colour change and staining caused by mild acid‑felting action (milling in dilute hot mineral acid) on textiles of all kinds and forms. The procedure is intended primarily for use where mild acid felting conditions are encountered in processes such as hat‑making and felt production or where assessment of susceptibility to acid‑felting is required for quality control and specification purposes.

Key topics and requirements

• Definition of test specimen and adjacent fabrics, and preparation for testing.
• Treatment of specimen by milling in a defined dilute hot mineral acid solution under controlled time and mechanical action (mild felting conditions).
• Rinsing and drying procedures following acid treatment.
• Assessment criteria: evaluation of change in colour of the specimen and staining of adjacent fabrics using the ISO grey scales for change and staining.
• Applicability to textiles in all forms; notes on reproducibility and use for quality control.

Typical use and users

Used by textile testing laboratories, quality control departments of textile and felt/hat manufacturers, material specification teams, and standards bodies. Typical applications include pre‑production qualification of dyed textiles, routine QC checks, comparative evaluations of dyeing processes and assessments of suitability of materials for processes involving acidic milling or similar treatments.

FAQ

Q: What is this standard?

A: ISO 105‑E14:1994 is the ISO test method that specifies how to evaluate the colour fastness of textiles to mild acid‑felting (milling in dilute hot mineral acid) by measuring colour change and staining of adjacent fabrics.

Q: What does it cover?

A: It covers specimen preparation, the acid‑milling treatment under defined mild conditions, post‑treatment rinsing and drying, and assessment of results using ISO grey scales for change in colour and staining.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers of felt and hats, dye houses, product specification and QC teams, and standards organisations involved in textile performance testing.

Q: Is it current or superseded?

A: This is Edition 3 published 15 September 1994. The published version has been subject to ISO systematic review and was confirmed in a later review cycle. Users should check with the national standards body or ISO for the absolute current status before formal use in procurement or regulatory compliance.

Q: Is it part of a series?

A: Yes — ISO 105 is a multipart series covering tests for colour fastness; E14 is one part (mild acid‑felting) and is complemented by many other parts addressing different agents, processes and assessment methods.

Q: What are the key keywords?

A: acid‑felting, colour fastness, milling, grey scale, textile testing, ISO 105, felt, hatmaking, dye stability.
