SUPPRESSION OF REABSORPTION OF DYE MIGRATED TO WASHING BATH

摘要

A process for inhibiting the re-absorption of migrating dyes in the wash liquor comprises introducing into a wash liquor containing a peroxide-containing detergent, from 0.5 to 150 mg, per litre of wash liquor, of one or more manganese compounds having the formula (1), (2), (3), (4), (5), (6) or (7) as defined in the specification. The manganese compounds do not exhaust at all on to cotton, polyamide or polyester fibres so that the compounds cannot lead to fibre discolouration problems.
