Abstract ㊀Considering the defects that chemical finishing on fiber materials has large energy consumption and potential fiber damages,enzymatic finishing of fiber materials under mild treating conditions were suggested.The oxidation mechanism of the ternary catalyst system of horseradish peroxidase (HRP ),hydrogen peroxide (H 2O 2)and β-diketone initiator acetylacetone (ACAC)were introduced,and its applications in bio-modifications of starch size,jute,silk protein were reviewed as follows.Methyl acrylate was graft copolymerized with starch to improve its film forming property onto the hydrophobic fibers.Acrylamide and hexafluorobutyl methacrylate were applied to modify jute fiber by enzymatic graft-copolymerization,respectively,realizing the hydrophilic or hydrophobic modification of jute fiber.Acrylic acid was used to enzymatically graft copolymerized onto silk fibroin to enhance the biomimetic mineralization effect of fibroin-based biomaterial.Furthermore,HRP-mediated graft copolymerization of methyl methacrylate onto silk sericin was also investigated to improve the formability of sericin-based biomaterials.In conclusion,HRP exhibits potential applications in bio-finishing of textile fibers and preparation of biomaterials.
