Full Description
Specifies a method for determining the resistance of the colour of textiles composed of natural and regenerated cellulose to the action of mild bleaching with sodium chlorite as ordinarily employed in textile processing. A specimen in contact with one or two 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 fabric(s) are assessed with the grey scale.
