Testing Robustness and Compatibility of Colour Damaging Washing Tests

Abstract

Abstract A significant aspect when selecting new bleaching agents is their reactivity on dyed textiles. In this paper the colour damaging effect of various the bleach activators are compared with that of tetraacetyl ethylene diamine. The tests were carried out according to ISO 105-C09 (diagnostic single wash test) and a similar test as well as the recently developed colour damaging profile test (20 wash cycles) using the AISE Dye Set. The results confirm that new bleach systems can differ significantly in their reactivity and selectivity towards individual dyeings from the conventional peroxycarboxylic acids or peroxycarboxylic acid generating activators. ISO 105-C09 appears to be suitable for prediction of the effect of conventional peroxycarboxylic acids but shows deficiency in the assessment of new bleach systems such as perimidic acids.
