Stiffness and Wrinkle-resistant Finishing of Cotton Fabric Based on Acrylamide and Glyoxal

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.
