Abstract

Face coverings such as a face mask are one of the important preventive measures amidst the COVID-19 pandemic, by limiting exhaled particles and reducing expiratory droplet spread. Adding a filter to face masks may offer extra protection against the virus. Nevertheless, there remains a significant concern where thicker, tightly woven materials of masks may reduce the ability to breathe comfortably, due to inadequate moisture management properties of woven fabric in existing disposable surgical face masks. Therefore, the study on the properties of air permeability, water vapor permeability, and flexural rigidity of a face mask fabric is highly essential. This study is aimed at analyzing the potential application of electrospun nanofibers fabricated from electrospinning technique, as filter inserts in commercial surgical face masks. The function of electrospun nanofiber filter (NF) inserted in commercial surgical face masks was introduced in the study. The results indicated the significant reduction in air permeability and water vapor permeability along with the additional usage of electrospun NF within the surgical face masks, due to the smaller fiber size and interspaces in the filter layer as analyzed from FESEM analysis. The percentage of air permeability value was slightly decreased by 15.9%, from 339.5 to 285.5 mm/s, whereas the value of flexural rigidity of surgical face masks with and without electrospun NF insert is 0.1358 and 0.1207 mg/cm, respectively. Hence, the NF inserts are recommended as the potential core component in a face mask.
电纺纳米纤维过滤片改善口罩水分管理性能
口罩等口罩是新冠肺炎大流行期间的重要预防措施之一,可以限制呼出颗粒物并减少呼气飞沫传播。在口罩上添加过滤器可以提供额外的病毒防护。尽管如此,仍然存在一个重大问题,即由于现有一次性外科口罩中编织织物的水分管理性能不足,较厚、紧密编织的口罩材料可能会降低舒适呼吸的能力。因此,研究口罩织物的透气性、透水性和抗弯刚度是非常必要的。本研究旨在分析由静电纺丝技术制成的电纺纳米纤维在商业外科口罩中作为过滤插件的潜在应用。介绍了电纺纳米纤维过滤器在医用外科口罩中的作用。结果表明,由于FESEM分析中分析的过滤层中较小的纤维尺寸和空隙,空气渗透率和水蒸气渗透率显著降低,同时在外科口罩中额外使用电纺NF。透气性值的百分比略有下降15.9%,从339.5降至285.5 mm/s,而具有和不具有电纺NF插件的外科口罩的弯曲刚度值分别为0.1358和0.1207 mg/cm。因此,推荐NF插入物作为口罩的潜在核心部件。
