指定一种方法，用于确定天然纤维素纺织品的颜色与通常在纺织品加工中使用的亚氯酸钠严重漂白的作用的抵抗力。与一个或两个指定的相邻织物接触的样品在亚氯酸钠溶液中处理，漂洗并干燥。用灰度级评估样品的颜色变化和相邻织物的染色

Specifies a method 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 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.
