. Purpose and Scope
1.1 This test method is designed to evaluate the colorfastness to non-chlorine bleach in home laundering of textiles which are expected to withstand frequent laundering. The fabric color changes resulting from non-chlorine bleach, detergent solution and abrasive action of five home launderings are evaluated.1.2 Results of this test method can be used for establishing care instructions. First establish the level of performance with non-chlorine bleach and if an effect is found, then retest with detergent alone. It may be necessary to use a water only wash to separate the effects of components like hardness, pH or chlorine content.1.3 Since the non-chlorine bleaches currently available contain ingredients other than the non-chlorine bleach; such as fluorescent whitening agents, bluing, etc., it is the total effect of these chemicals on the color change that is being evaluated.
