Multifunctional carboxylic acids in DP finishing with BTCA and CA

Cotton fabric was modified with polycarboxylic acids in combination with so dium hypophosphite as a catalyst to impart durable press properties to cell ulosic material. The ester linkages built are resistant to multiple home la underings. The amount of BTCA, CA, aconitic acid, citraconic acid, and itac onic acid extracted from the treated cotton fabric as a function of washing time and washing agent was investigated. It was found that the commercial detergent showed the greatest impact. Furthermore, the influence of various aliphatic and aromatic multifunctional carboxylic acids on the durable pre ss properties was studied.
