A novel PVA silver-loaded non-woven fabric was prepared by the dehydration reaction of polyvinyl alcohol (PVA) followed suffocation and silver ion exchange. The optimum conditions for preparing silver-loaded non-woven fabric are as follows: dehydrating temperature 160℃, dehydrating time 90min, sulfonated temperature 90℃ and su]fonated time 70 min. Antibacterial characteristics of silverloaded non-woven fabric were investigated. The results indicated that Ag+ exchange capacity of silverloaded non-woven fabric is 2. 29 mg/g and bactericidal rates of the silver-loaded non-woven fabric against both E. coli K12 W3110 and S. aureus IFO 12732 are more than 90% within 30 min and 99%within 2h. The silver-loaded non-woven fabric can be used as clothing, wound dressing and air filtration materials.
