DIN Standards Committee Materials Testing

Overview

This part of ISO 105 specifies a method for determining the resistance of the colour of wool and part-wool textiles to the action of soap and sodium carbonate solutions used in alkaline milling (severe method) or of a soap solution only (mild method). The mild method can be applied to light- or medium-weight wool (or wool-containing) clothing fabrics. A specimen of the textile in contact with either two single-fibre adjacent fabrics or a multifibre adjacent fabric shall be milled in a jar containing steel balls and a solution of soap and sodium carbonate or a solution of soap. In the first case (severe milling), the severity of the action is controlled by means of a test-control dyeing milled separately in the same way. After rinsing and drying separately, the change in colour of the specimen and the staining of the adjacent fabrics shall be assessed with the grey scales or instrumentally. The Committee responsible for this standard is NA 062-05-11 AA "Farbechtheit von Textilien - Deutsche Echtheitskommission DEK" ("Colour Fastness of Textiles - German Colour Fastness Committee") at DIN.
