In order to prevent cotton wrinkling, hydroxyl groups in the cellulose chain of cotton are partially crosslinked to keep the chain fixed relative to each other with dimethylol dihydroxy ethylene urea (DMDHEU). However, DMDHEU suffers disadvantages of reduced fabric strength and releasing of free formaldehyde. Recently, 1,2,3,4-butane tetracarboxylic acid (BTCA) has been explored as a new wrinkle-resistant agent providing similar performance to that of DMDHEU. In BTCA finishing, catalyst of inorganic phosphorus-containing acids was used but such phosphorus compounds have an adverse impact on the environment. In this paper, nano-TiO₂ was used as a co-catalyst with sodium hypophophite in the treatment of cotton with BTCA, and the final properties were assessed.

In this paper, a T shape macro-molecule was designed to improve the stiffness and wrinkle-resistant property of cotton fabric. In the finish process, the radical polymerization and condensation reaction step by step were introduced. The results show that the stiffness and wrinkle-resistant property of cotton fabric were improved efficiently and rapidly. The stiffness of finished cotton fabrics can reach from 0.13 to 2.67 N.m, the crease recovery angle from 147.9° to 226.2°. The whiteness improve a little. Scanning electric microscope shows the surface of modified cotton fabric has layer of material; Fourier transform infrared spectroscopy shows the modified cotton fabric has amide compound; The thermogravimetric analysis shows that the thermal stability was improved a little.
