Composited Silver-Contained PA 6 Electrospun Fibers with Spunbond Nonwovens for Filtration Applications

Abstract:

By using electrospinning method, polyamide 6 (PA 6) nanofibers containing 1 wt% of AgNo₃ were spun from different concentrations solutions (15-25 wt%) for use as composite filter media. The silver ions in PA 6 nanofibers were reduced by ascorbic acid solution to silver particles offering antibacterial properties to the final filter after electrospinning. The results show, fibers with mean diameters less than 160 nm were prepared for use as filter media by electrospinning. The diameter of electrospun fiber was proportioned to the viscosity of PA 6 solution but was inversed to the applied electrical voltage. The viscosities of PA 6 solution were decreased by adding of AgNo₃ from which brought more irregular formation of electrospun fibers. The filtration efficiency of spunbond nonwoven would improve greatly by compositing the electrospun PA6 web with or without silver.
