AATCC TM172-2016, Colorfastness to Powdered Non-Chlorine Bleach in Home Laundering

 

Developed in 1988 by AATCC Committee RA60 (revised 2010, reaffirmed and editorially revised)

 

1.  Purpose and Scope

 

1.1  This test method is designed to evaluate the colorfastness to powdered non-chlorine bleach in home laundering of textiles which are expected to withstand frequent laundering.   The fabric color changes resulting from powdered non-chlorine bleach, detergent solution and abrasive action of five home launderings are evaluated.

1.2  First establish the level of performance with powdered 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 powdered non-chlorine bleaches currently available contain ingredients other than the powdered 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.
