A process for providing localized variation in the colour density of fabrics

The method for locally changing the chromatic density on dyed fibre surface includes use of catabolic enzyme for cellulose to treat dyed fibre in aqueous mother liquid containing 2- or 3-valence cations and chelating agent. The mole ratio of cation to chelating agent is 1 to 0.1-50.
