To avoid using formaldehyde which is a potential carcinogen polycarboxylic acids (PCA) such as butanetetracarboxylic acid [7] , citrie acid [3] and a mixture of maleic acid and itaconic acid [2, 6] bave been used in durable press (DP) finishing of cotton. These PCAS are used in RDF processing of cotton in the presence of reactive and direct dyes [9,11] Cotton fabries dyed by the ODF method with reactive and direct dyes in the presence of butanetetracarboxylic acid and a mixture of butanetetracarboxylic acid and citric acid show excellent color strength and dye fixation [9,11] However, the PCA-containing ODF process generally requires a high temperature, i.e. higher than 180*C, to fix the OCA and dye [9]. Furthermore, the most efficient catalyst in the esterification reaction of polycarboxylic acid with cellulose-sodium hypophosphite-could cause shade changers during the IDF process [10].
