By using electrospinning method, polyamide 6 (PA 6) nanofibers containing 1 wt% of AgNO3 were spun from different concentrations solutions (15,17,19,21,23wt%) 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.
本研究以尼龍6之15,17,19,21及23wt%溶液,並添加入硝酸銀1wt%製作具抑菌性的靜電紡絲複合濾網。研究發現,隨著尼龍溶液的黏度增加,所製得纖維的細度越粗。在固定尼龍濃度下,電壓低時所紡成的纖維細度較粗,且纖維網的結構較不規則。添加1wt%的硝酸銀於尼龍中發現,尼龍溶液的黏度以及導電度皆會下降,且會使纖維網的結構變得更不均勻。添加了硝酸銀的尼龍溶液,在較低的電壓及低固含量尼龍溶液條件下,單根纖維的表面皆有斷纖及奈米液滴產生。
