Abstract

The Covid-19 pandemic period caused attention to the importance of medical masks. Various studies show that mask fabrics should not be ordinary. Uncontrollably produced masks with poor quality have become an important problem in the market. Based on the idea that viruses spread by binding themselves to environmental bacteria and water droplets, it is assumed that the basic filtering efficiency of masks is of primary importance and requires the use of masks with a certain filtering ability. The purpose of the present study was to produce fabric masks from Polyethylene Terephthalate (PET), and to investigate the filtration efficiency. Masks were produced from the developed PET fabric and widely used Meltblown (MB) fabric, which is known to have a high filtration rate and their filtration efficiencies were compared. EN 14683 BFE methods was used in laboratory setting to measure the filtration efficiency of the masks. It was found that the MB/3-layer mask had 99.7% (SD±0.2) capacity of filtering microorganisms and the 3-layer ART/Mask in the developed PET structure was capable of filtering microorganisms at a rate of 96.8% (SD±2.7). When the filtration efficiency of the masks detected for each microorganism was compared separately, no statistically significant differences were detected (p>0.05). The tested mask was found to have a similar high microbial filtration rate to the mask made of meltblown fabric. This suggests that it will reduce the spread of viruses by attaching themselves to bacteria from sick individuals. It is also it can has protective effect for nosocomial infections.

Özet

Covid-19 pandemi dönemi tıbbi maskelerin önemine dikkat çekmiştir. Araştırmalar, üretilen maskelerin herhangi bir kumaştan olmaması, belirli özelliklerinin olması gerektiğini göstermektedir. Ancak kontrolsüz olarak üretilen kalitesiz maskeler piyasada önemli bir sorun haline gelmiştir. Virüslerin çevredeki bakteri ve su damlacıklarına tutunarak yayıldığı fikri, maskelerin temel filtreleme etkinliğinin belirli bir düzeyde olması gerektiğini zorunlu kılmaktadır. Bu çalışma da polietilen tereftalattan (PET) kumaştan maske üretilmesi ve filtrasyon etkinliğinin araştırılması amaçlanmıştır. Geliştirilen PET kumaştan ve yaygın olarak kullanılan yüksek filtrasyon verimliliği olduğu bilinen Meltblown (MB) kumaştan maskeler üretilmiş ve filtrasyon verimlilikleri karşılaştırılmıştır. Maskelerin filtrasyon verimliliğini ölçmek için laboratuvar ortamında EN 14683 BFE test standardı prosedürleri uygulanmıştır. MB/3 katmanlı maskenin mikroorganizmaları %99,7 (SD±0.2) filtreleme kapasitesine sahip olduğu ve geliştirilen PET yapısındaki 3 katmanlı ART/Maske'nin mikroorganizmaları %96,8(SD±2.7) oranında filtreleyebildiği tespit edilmiştir. Her bir mikroorganizma için tespit edilen maskelerin filtrasyon verimlilikleri ayrı ayrı karşılaştırıldığında, istatistiksel olarak anlamlı bir farklılık tespit edilmemiştir. (p>0,05). Test edilen maskenin meltblown kumaştan üretilen maskeyle benzer oranda yüksek mikrobiyal filtrasyona sahip olduğu bulunmuştur. Bu durum hasta bireylerden bakterilere bağlanarak yayılan virüslerin çevreye bulaş oranını azaltacağını düşündürmektedir. Ayrıca PET'ten üretilen maskelerin hastane enfeksiyonlarına karşı koruyucu etkisi olabileceği öngörülmektedir.
