This part of- IS0 105 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms to the action of hot water. The method is mainly applicable to wool and textiles containing wool.
A specimen of the textile (textiles of all kinds and in all forms) in contact with adjacent fabrics is rolled around a glass rod, treated with slightly acidified hot water and dried. The change in colour of each specimen and the staining of the adjacent fabrics are assessed with the grey scales.
