摘要
利用nano-Ag/nano-TiO2对丙纶熔喷非织造材料进行抗菌功能改性,通过改变等离子体处理时间、nano-Ag/nano-TiO2配比、改性处理时间、改性温度等工艺参数,成功制备出具有抗菌功能的熔喷非织造空气过滤材料,并进行了相关性能测试。结果表明:nano-Ag/nano-TiO2改性的最佳工艺为nano-Ag/nano-TiO2配比36:1,反应温度30℃,改性时间10 min。Nano-Ag/nano-TiO2成功附着在材料表面,且未破坏材料原有纤维结构,过滤性能没有发生大的变化,与未改性的材料一样具有较好的过滤性能。PP熔喷非织造材料经nano-Ag/nano-TiO2改性后,具有明显的抗菌杀菌功能,且有较好的抗菌持久性。
Nano-Ag/nano-TiO2 was used to modify polypropylene melt blown nonwoven materials for antibacterial function.By changing the technological parameters such as plasma treatment time,nano-Ag/nano-TiO2 ratio,modification treatment time and modification temperature,melt blown nonwoven filter material with antibacterial function was successfully prepared,and the related performance of the filter material was tested.The results showed that the best modification process of nano-Ag/nano-TiO2 was the ratio of nano-Ag/nano-TiO2 36:1,reaction temperature 30℃,modification time 10 min.Nano-Ag//nano-TiO2 was successfully attached to the surface of the material without destroying the original fiber structure,and the filtration performance did not change greatly.It still had good filtration performance as the unmodified material.PP melt blown nonwoven material modified by nano-Ag/nanoTiO2 had obvious antibacterial and bactericidal functions and good antibacterial durability.
