Cotton cellulose dyed with direct cotton dyes was oxidized with buffered sodium hypochlorite solutions under different conditions. An attempt was made to correlate the extent of degradation of cellulose and the oxygen consumption during oxidation with the chemical constitution of dyes. The behavior of dyed samples during exposure to Fade-Ometer light has also been examined to study the influence of the constitution of the dyes. The results are discussed with a view to correlating the behavior of these dyes with that of leuco vat dyes under similar conditions.
