Abstract:

This study uses previously proposed spectrophotometric pass/fail criteria for the assessment of oxidative-bleach fading of cellulosic dyes on cotton during repeated washing. A high level of correlation (88%) has been obtained between the fading exhibited by optionally aftertreated direct dyes in the UK-TO test and that after 20 domestic machine washes in the presence of a detergent containing an oxidative-bleach system. The correlation, and ultimate utility of the test method, is further improved when preceded by an ISO 105 C06/C2S wash fastness test to screen out dyes having a low intrinsic fastness to washing.
