Antibacterial properties of padded PP/PE nonwovens incorporating nano-sized silver colloids

摘要: This paper deals with the effects that nano-sized silver colloids have on antibacterial properties of PE/PP nonwovens against three kinds bacteria: Staphylococcus aureus, Klebsiella pneumoniae, and Escherichia coli. These comprise nanoparticles are a non-toxic non-tolerant disinfectant. used as back sheets or coverstocks baby diapers, adult sanitary napkins, wipes. materials readily contaminated by bacteria present in moisture dirt can cause disease. We finished using normal dipping–pad–dry method. From SEM images, we determined were generally dispersed well surface nonwoven fibers. AATCC-100 test method to study treated fabrics. Bacteria disinfected completely below count 10 cells after min when samples ppm colloids. The ethanol-based silver/sulfur composite colloid (SNSE) has best efficacy compared other particles having smallest sizes gave higher dispersibilities strongest efficacies.
