Textiles — Tests for colour fastness — Part X08: Colour fastness to degumming

Describes a method for determining the resistance of the colour of textiles of all kinds, except loose fibre, to the action of soap solutions such as those used in degumming raw silk. A specimen of the textile in contact with adjacent fabrics is treated with a soap solution, then rinsed and dried. The change in colour of the specimen and the staining of the adjacent fabrics are assessed with the grey scales.
