Improved dyeing properties of cotton crosslinked with polycarboxylic acids are produced by addition of reactive nitrogenous additives, such as alkanolamines and hydroxyalkyl quaternary ammonium salts, to the treatment formulation. Both N ‐methylolamides and polycarboxylic acids are effective for crosslinking cotton and bonding reactive nitrogenous additives to the cellulosic substrate, but dyeing characteristics of the finished fabrics are very different. In this study, the influence of the reactive additives and dyebath pH on the colour yields of cotton crosslinked with polycarboxylic acids and then dyed with anionic dyes were determined. Emphasis is on the dyeing properties of cotton finished with 1,2,3,4‐butanetetracarboxylic acid or citric acid non‐formaldehyde crosslinking agents, and alkanolamine hydrochloride or hydroxyalkyl quaternary ammonium salt additives.
