Nano Killer Mask

Nanovia Killer Face mask – barrier against microorganisms and fine dust particles


Face mask materials are intended for producing surgical masks or face masks against microorganisms and dust particles. The materials are also useful for the production of disposable interchangeable filters for face masks e.g. for athletes and motorcyclists.

Highlights of fabric laminates with nanofiber layer as compared to traditional SMS laminates for use in face masks

Nanovia face mask materials are highly effective filter materials enabling filtering microorganisms and airborne dust. They provide excellent physiological comfort when using them owning to their excellent breathability and moisture permeability.

Nanovia face mask fabric laminates form a barrier against penetration of microorganisms – bacteria, viruses, mould and fungi spores or dust particles on the principle of their mechanical detection.

The following types of materials are offered by Nanovia within this group of materials:

  • Nanovia Surgical Mask 20 (SM20) – is a material suitable for manufacturing Class I surgical masks according to EN 14683

  • Nanovia Surgical Mask 40 (SM40) – is a material suitable for manufacturing Class II surgical masks according to EN 14683

  • Nanovia AntiVirus – is a material suitable for manufacturing class II surgical masks according to EN 14683, it provides 100% capture of allergens and bacteria and 99.9% capture of viruses without impairing the permeability and vapour permeability of the material as compared to surgical masks.

  • Nanovia Dust Protection PM 2.5 – is a material intended for the manufacture of face masks designed to filter out airborne dust and allergens of 2.5 µm in size.

Nanovia Face mask material resistance against the penetration of various species of microorganisms, dust particles and allergens is ensured by the nanofiber layer (Fig. 1) which is closed inside the fabric laminate. In principle, all fabrics are a three-layer sandwich which middle layer has a nanofiber structure. The size of interfiber pores in this structure is substantially smaller than the size of microorganisms, spores, allergens or dust particles. For example, Staphylococcus aureus size is about 1 micrometre, H1N1 virus size is approximately 150 nanometres (Fig. 2).

The above materials are produced by a combination of various kinds of non-woven fabrics – spunbond, meltblown – with respect to the parameters required by the standards. Mechanical consistency of the individual laminate layers is assured by fabric lamination process.

Nanofiber Production

When it comes to production of nanofibers itself, we use Nanospider™ technology based on the principle of spinning the polymer solution in electrostatic field.

We use laboratory machines intended for the development of new materials and preparation of samples. Industrial production of barrier fabrics, filter materials, nanofiber membranes and other nanofiber materials is provided by several industrial machines Nanospider™.

  • maximum operating width of 1650 mm, nanofiber layer maximum width of 1600 mm

  • maximální zpracovatelný průměr návinu je 1200 mm

  • maximum processable winding diameter of 1200 mm

In industrial production of nanofiber materials for barrier fabric and filter materials we use mostly polymers PA6 and PVDF. The production itself takes place in an area of cleanliness class 8 according to ISO 14664 which is part of our production plant.
