Cellulosic fabric has been treated with anionic (chloroacetatic acid) and cationic (3-chloro-2 hydroxypropyl trimethylammonium chloride) materials followed by the application of a polycation (cationized glycerin) and a polyanion (1,2,3,4-butanetetracarboxylic acid) to improve the fabric durable press performance. It is observed that the ionic crosslinks stabilize the cellulose using ionic materials which do not release hazardous reactive chemicals but at the same time provide improved wrinkle recovery angle as well as complete strength retention in treated goods. The polyelectrolyte, the ionic content of the fabrics, and various features of the application procedure have been varied to optimize the results and to develop an in-depth fundamental physical and chemical understanding of the stabilization mechanism.
