Colorfastness to bleaching: Sodium chlorite: Severe

This method is intended for determining the resistance of the colour of natural cellulose textiles to the action of Severe bleaching with sodium chlorite as ordinarily employed in textile processing

A specimen of the textile in contact with specified adjacent fabrics is treated in a sodium chlorite solution, rinsed and dried. The change in colour of the specimen and the staining of the adjacent fabrics are assessed with the grey scales.
