Narrow Results

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.

In this paper, a monomer finish reagent synthesized by acrylic amide and glyoxal finished polyester cotton fabrics to improve the stiffness and wrinkle-resistant property. The results show that: the monomer finish reagent was very effective to improve the stiffness and crease recovery property; The breaking strength also improve a lot, the stiffness can improve from 0.05(N.m) to 1.15(N.m), the breaking strength of original polyester cotton fabric is 308.5N, after finished, the value can reach 362.5N, the crease recovery angle can improve from 209.2° to 260.2°. The whiteness improve a little. Analysis of FT-IR show there are amide compound on polyester cotton fabrics finished by finish reagent. The thermogravimetric analysis show that the thermal stability of polyester cotton fabrics have a little improvement.
