外文摘要：Polyhexamethylene biguanide (PHMB) is a new type of antibacterial finishing agent which has good antibacterial effect and high safety, but poor heat resistance and the lack of functional group limit its effective application in polyester fibers. In this work, PHMB was highly functionalized by epoxy modification. Thus, an antibacterial composite polyester fibers consisting of modified PHMB, ZnO nanoparticles, and PET matrix were successfully fabricated through melt spinning, which exhibited great morphology without fibrous fracture and thermostability. In addition, the antibacterial activity test indicated that this composite fibers possess effective antibacterial effect and washable resistance, which antibacterial rates against Escherichia coli (E.coli) and Staphylococcus aureus (S. aureus) still could reach 90.4% and 92.2% after 50 times of washing, respectively. And this strategy can be extended to the fabrication of other antibacterial polyester fibers.
