Polycarboxylic acids are used as an alternative nonformaldehyde durable press finishing agents for cotton fabrics. Previous studies have shown that polycarboxylic acids esterify with cotton cellulose through intermediate formation of a cyclic anhydride. Cotton cellulose, due to the presence of hydroxyl groups, is a very active substrate. To understand the mechanism of ester formation, esterification reactions were studied on aluminum surfaces by infrared attenuated total reflectance (ATR) spectrometry. The infrared data showed that a five-membered cyclic anhydride is formed as an intermediate, that esterifies with the crosslinking agents. The data also demonstrated that formation of anhydride increases with temperature and also in the presence of a catalyst.
