Research progress of low-temperature bleaching of cotton fabrics catalyzed by metal complexes

In order to study the application of metal complex catalysts in low-temperature bleaching of cotton fabrics, and to develop metal complexes with better performance, the relevant researches at home and abroad were reviewed. The metal complexes based on several types of ligands such as cyclic polyamines, Schiff bases, pyridines, porphyrins and phthalocyanines used in low-temperature bleaching were introduced and examined. The bleaching performance of the metal complex/hydrogen peroxide bleaching system and the traditional cotton fabric oxygen bleaching system were compared and analyzed. The results show that the metal complexes are a type of efficient catalysts, which effectively solve the problems of high energy consumption and serious fabric damage in the traditional bleaching process. Finally, the deficiencies of the current metal complex catalysts are pointed out, and the future research and development of the metal complex catalysts are prospected.
