Synthesis and Application of a Novel Polymer as an Antimicrobial and Water and Oil Repellent Finishing Agent for Cotton
A novel polymer APFC containing quaternary ammonium and perfluoroalkyl groups was designed and prepared by emulsion polymerization using interfacial redox initiator system, the average size of the emulsion particles was about 103nm, APFC was applied on cotton fabrics to show the antimicrobial activities and optimum water and oil repellency by a pad-dry-cure process, the water repellency scores and oil repellency ratings of the cotton fabrics finished with APFC can reach 100 and 6, respectively. We evaluated the efficacy of the antimicrobial activity of cotton fabric finished with APFC , the antimicrobial test result of the finished cotton fabric showed a 97.4% reduction in the number ofStaphylococcus aureus(ATCC6358) and a 90.5% reduction in the number ofEscherichia coli(ATCC8099).
