Abstract: A bionic enzyme metallophthalocyanine compound metalloPhthalocyanine MPcR was synthesized and used in textile bleaching process and the catalytic effect was discussed by single factor experiment and orthogonal tests. The optimum bleaching recipe consists of utilizing a bath containing JFC (2g/L), MA-AA( 0.2g/L), 30% H2O2 (30g/L) and catalyst MPcR (15μmol/L) . The treatment is carried out at 80℃ (pH 9.5) for 60min . The bleaching process is energy-saving besides its superior bleaching results.
