Abstract
Ethylene urea and paraformaldehyde with different mole ratios are used as source materials to synthesize dimethylol ethylene urea/monomethylol ethylene urea (DMEU/MMEU) prepolymer resin. The DMEU/MMEU prepolymer resin is then applied to cotton fabrics for wrinkle-resistant finishing. The influence of DMEU/MMEU prepolymer resin on crosslink structures in the treated fabrics is studied. The results show that the formaldehyde content in the treated cotton fabrics with various crosslink structures is determined by the mole ratio of paraformaldehyde in the source mixture and the curing temperature in the finishing process. The crosslink integrity shows various effects on the physical properties of the treated fabrics. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 489–493, 2000
