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.%通过对PVA纤维的脱水、磺化和离子交换作用制备了一种新型的栽银无纺布.载银无纺布制作的最佳工艺条件为脱水温度160℃;脱水时间90 min;磺化温度90℃;磺化时间70min.调查了载银无纺布的抗菌活性,结果表明,该载银无纺布的Ag+交换量为2.29mg/g,对于E.coli K12 W3110和S.aureus IFO12732,30min内的杀菌率均在90%以上,2h之内的杀菌率为99%.该载银无纺布可被使用于服装、医用敷料和空气过滤材料.
