文摘

Cross-linking agents are applied to cotton in the textile industry to produce wrinkle-resistantcotton fabrics and garments. In recent years, extensive efforts have been made to usemultifunctional carboxylic acids to replace the traditional formaldehyde-based dimethyloldihydroxyethyleneurea (DMDHEU). In this research, we studied the polymerization of maleic acid(MA) to form oligomeric poly(maleic acid) (PMA) in an aqueous solution. Both the Fouriertransform- (FT-) Raman spectroscopy and the pH titration data of the MA polymerizationproducts with different reaction times show disappearance of the monomer (MA) and formationof the polymer (PMA) during the polymerization process. We found that the PMA thussynthesized is an effective cross-linking agent for cotton cellulose. We compared PMA with themodified low-formaldehyde DMDHEU as durable press (DP) finishing agents for cotton. Thecotton fabric treated with PMA has wrinkle resistance similar to that treated with the DMDHEUwith improved tensile strength retention. The oligomeric PMA appears to be a very promisingnew nonformaldehyde DP finishing agent for the textile industry.
