Application of direct dyes on silk fabric suffer from problems of poor fastness properties as well as decrease in dye fixation .A formaldehyde donor agent, i.e. Hexamine, (hexamethylene tetramine), was used for improving dye fixation and wet fastness when added to the printing paste during printing silk fabric with a direct dye containing free amino groups (Diamine Supra Blue GRL200% ).
