摘要:
A list of highly suitable textiles and a method to combine them into a durable reusable filtration medium with high particles filtration efficiency (PFE) and breathability that lasts over 50-75 laundering cycles. Filtration medium achieves PFE only through mechanical means, without fragile and harmful physicochemical pre-treatments. Different textiles are assembled considering their individual breathability and their complementary in terms of PFE on different particles' sizes to achieve good breathability and high PFE on a large range (20 nm-4 μm) after many laundering cycles, or several layers of the same textile are paired, while varying the fibers' orientation and dimensions in each layer to increase efficiency. This assembling method highly improves PFE, service life and performances' stability of the filtration medium by addressing structural weaknesses linked to anisotropy in each layer, and by protecting their fine fibers from mechanical wear and clogging through a face-to-face closed filtration cell-type pairing.
