A polymaleic acid dye based on poly(maleic anhydride) was synthesised and evaluated in the dyeing of cotton. A series of dyeing auxiliaries were examined, and results showed that a composite auxiliary agent consisting of 20 g/l of zinc nitrate and 30 g/l of dicyandiamide was the most effective when a conventional pad‐dry‐cure dyeing process was used. The fixation could reach 99% and the wash and dry rub fastness could reach grade 4 and grade 4–5 respectively. The decrease in tearing strength of the dyed cotton was between 17.8 and 32.1%.
