Nanofiber 3PLY FILTER nanosilver®

without chemicals, adhesives and glues. Thin layer of nanofiber textile with firmly fixed molecules of colloidal silver is laminated between two layers of support and cover layer, specially developed for this application. Filters viruses and bacteria with efficiency of 92%. 

Filter construction consist of three-ply textile material, support and cover layers of non-woven PES viscosis and inner layer made of Polyamid 6 nanotextile with firmly fixed molecules of silver.

Functional nanotextile is made by endless fibre with the diameter 200 - 600 nm made by electro-spinning method with its basis weight of 3 g / m2. Cover layer has basis weight of 35 g / m2, overall basis weight of this membrane is 73 g / m2.

Size of SARS-CoV-2 virus particles are between 80-150 nm. The penetration of particles of this size through the filter material is around 8%, which confirms the filtration efficiency of 92%. The test was performed at a permeable speed of 10.7 cm / s.
