We examined catalyrtic activities of mono- or disodium salts of fumaric, maleic, and itaconic acids for the reaction of 1,2,3,4-butanetetracarboxylic acid ( BTCA ) with cotton cellulose. Evidence for esterification and crosslinking of cellulose with BTCA in the presence of these carboxylic acid salts was shown by improved durable press rating and conditioned wrinkle recovery angles of the treated fabric and the presence of ester groups in the treated fabric by FTIR analyses. In addition, FTIR and FT- Raman analyses revealed that these carboxylic acid salts did not participate in formation of permanent linkages with cellulose and BTCA.
