Polyester yarns are widely used in antimicrobial fibers and fabrics.In recent years,many antibacterial substances have been on their way to commercialization. Alternative antibacterial substances are becoming the main purpose of antibacterial yarns processing research.Most of the antibacterial substances are loaded directly on yarns by dipping or coating methods.The aim of this work was to immobilize silver-loaded chitosan onto polyester yarn through a 2-dipping-2-rolling textile finishing process.The coating and the structure of sliver-loaded chitosan antibacterial yarn were studied and analyzed by using scanning electron microscope.The antibacterial activities against Staphylococcus aureus and Escherichia coli were tested.The experimental results showed that all polyester yarns coated by sliver-loaded chitosan have good antibacterial properties,and R-3group has better antibacterial effect.
