Abstract
Surgical masks have been widely used in the past for protection purposes against infection as a hygiene product.
Masks, which are often used by healthcare professionals, are also widely used by the general public during pandemic
periods. Surgical masks were designed in various ways according to colour, nose strip, earloop, grams per square meter
and several layers. Some performance features are expected from these masks according to certain standards. In this
study, it has been studied on multi-layered surgical masks. Thickness, air permeability, bacterial filtration efficiency and
differential pressure properties of these masks consisting of polypropylene spun bond and melt-blown layers were
investigated. The effects of an increase in grams per square meter, the number of layers and the melt-blown layer on
the mentioned properties were determined. As a result; it has been observed that the optimal mask is one of the 4-ply
masks. Also, it has been concluded that increasing the number of layers does not always provide an increase in
performance; instead, an increase in grams per square meter can meet the expectation. Therefore, it can be said that
it is necessary to determine the appropriate weight in grams and the appropriate number of layers with suitable raw
materials to provide the expected features from the surgical masks.
