ABSTRACT:
The fastness of direct dyes on cellulose substrates is improved by after-treatment with the reaction product of a quaternary polyalkylene polyamine with an N-methylol resin precursor, and heat curing in the presence of a catalyst. The unfixed portion of reactive dyes substantive to cellulose may also be given improved wet and light fastness by this treatment.
