Abstract
Durable press (DP) or anti-wrinkle finishing is usually carried out for improving wrinkle properties of cotton fabrics. The treated fabrics can maintain good appearance as a result of crosslinking between cellulose chains with finishing agents, inhibiting the movement of cellulose chains. Despite the good crosslinking performance of formaldehyde-based compounds, the concern about potential harm of free formaldehyde potentially releasing from the fabrics to the environment or human beings inspires people to develop formaldehyde-free agents. Among them, polycarboxylic acids (PCAs) show the most outstanding performance, especially 1,2,3,4-butanetetracarboxylic acid and citric acid. To improve the mechanical properties or whiteness of the treated fabrics, novel finishing agents attract the great interests of researchers. Besides, new catalysts or additives have been developed. The multifunctional finishing of cotton fabrics such as the combination of DP finishing with antibacterial, or flame retardancy, or anti-ultraviolet finishing has also been widely investigated.
