Current guidance by leading public health agencies recommends wearing a 3-layer cloth-based face mask with a middle non-woven material insert to reduce the transmission of infectious respiratory viruses like SARS-CoV-2. In this work we explore the material characteristics for a range of readily available non-woven materials and their sub-micron particle filtration efficiency (PFE), with the aim of providing evidence-based guidelines for selecting appropriate materials as inserts in cloth-based masks. We observed a wide range of ideal PFE for the tested non-woven materials, with polypropylene, Swiffer and rayon/polyester blend providing the highest PFE and breathability. Our results suggest that materials comprising loose 3D fibrous webs (e.g. flannel, Swiffer and gauze) exhibited enhanced filtration efficiency compared to compressed counterparts. Common modifications to fabrics, such as water-resistant treatment and a sewn seam were also investigated. Overall, we demonstrate that adding an appropriate non-woven material as an insert filter can significantly improve the performance of cloth-based masks, and there exist suitable cellulose-based alternatives to polypropylene.

基于布的面罩插入物的非织造材料：材料性能与亚微米气溶胶过滤之间的关系

领先的公共卫生机构的当前指南建议佩戴三层基于布的面罩，并在中间插入非织造材料，以减少传染性呼吸道病毒（如SARS-CoV-2）的传播。在这项工作中，我们探索了各种现成的非织造材料的材料特性及其亚微米级颗粒过滤效率（PFE），旨在为选择合适的材料作为基于布的口罩中的插入物提供循证指南。。我们观察到了用于测试非织造材料的各种理想PFE，其中聚丙烯，Swiffer和人造丝/聚酯共混物提供了最高的PFE和透气性。我们的结果表明，包含松散3D纤维网的材料（例如绒布，Swiffer和纱布）的压缩效率高于压缩物。还研究了对织物的常见修饰，例如防水处理和缝线接缝。总的来说，我们证明添加适当的非织造材料作为插入式过滤器可以显着提高基于布的口罩的性能，并且存在合适的基于纤维素的聚丙烯替代品。
