Full title and description

ISO 105‑E14:1987 — Textiles — Tests for colour fastness — Part E14: Colour fastness to acid‑felting: Mild. This short technical specification defines a laboratory procedure for subjecting textile specimens, in contact with adjacent fabrics, to mild acid felting conditions and assessing any change in colour or staining. The 1987 edition is available in English and French; a later revised edition (1994) supersedes it.

Abstract

The method mills a textile specimen together with adjacent fabrics in a dilute, hot mineral acid solution under mild felting conditions, then rinses and dries the specimens. The change in the specimen's colour and the staining of the adjacent fabrics are evaluated using grey scales for assessment of colour change and staining. The procedure is intended to simulate acid‑felting actions encountered in hatting and felt manufacture.

Scope

This part of ISO 105 specifies a test method for determining the resistance of dyes on textile materials to the action of dilute, hot mineral acids under mild felting (milling) conditions. It applies to textiles in all forms where acid‑felting action may occur (for example in the hatting and felt industries) and covers the procedures for conditioning, acid treatment, rinsing, drying and visual assessment of colour change and staining. Note: the 1987 edition was later replaced by a 1994 edition that expands and updates the method.

Key topics and requirements

• Definition of test purpose: assess colour change and staining after mild acid felting.
• Specimen preparation and choice of adjacent (undressed) fabrics for staining assessment.
• Acid solution composition and temperature control for the mild felting procedure.
• Milling (felting) action—mechanical conditions and duration.
• Rinsing, drying and conditioning steps after treatment.
• Assessment criteria: grey scales for change in colour and for staining of adjacent fabrics (visual comparison).

Typical use and users

Used by textile test laboratories, quality assurance departments of textile and felt/hat manufacturers, dye and chemical suppliers, and conformity assessment bodies to evaluate product performance under acidic felting conditions. It is primarily relevant where felting processes or exposures to dilute hot acids are part of product manufacture or use.

FAQ

Q: What is this standard?

A: ISO 105‑E14:1987 is a short ISO test method describing a laboratory procedure to assess the colour fastness of textiles to mild acid‑felting (milling) action; it is part of the ISO 105 family for colour‑fastness testing.

Q: What does it cover?

A: It covers specimen handling, milling in a dilute hot mineral acid solution under mild conditions, rinsing/drying, and visual assessment of colour change and staining using grey scales.

Q: Who typically uses it?

A: Textile test labs, manufacturers (especially felt and hat producers), dye manufacturers, and quality or compliance personnel who need to evaluate resistance to acid‑felting.

Q: Is it current or superseded?

A: The 1987 edition is withdrawn and has been superseded by ISO 105‑E14:1994. The 1994 edition has been subject to systematic review and is the published/recommended version in ISO's catalogue.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (Textiles — Tests for colour fastness), which contains many test methods for different agents (washing, light, perspiration, milling, felting, spotting, etc.).

Q: What are the key keywords?

A: Colour fastness; acid‑felting; milling; grey scale; adjacent fabrics; textiles testing; ISO 105; hatting; felt.
