Abstract
The article is aimed at evaluating the air permeability of various types of non-woven fabrics prepared by Spunbond, Spunbond-Meltblown-Spunbond technology and non-woven fabrics reinforced mechanically by needling and thermal calendering. These are commercially available non-woven fabrics with various mass per unit area and thickness made of 100 % polypropylene, without special surface finish. By combining individual types of non-woven fabrics, three-layer and four-layer textile materials were prepared, meeting the minimum requirement of technical standardization information TNI CWA 17553 for air permeability, intended for application in the community face masks. As part of the experimental works, the effect of increased humidity on the air permeability of three-layer non-woven fabrics was verified as well.
