Fibertex Nonwovens has developed a versatile component, which is designed to improve the filtration efficiency of protective face masks and also extend their safe storage period.

“By utilizing premium, high-efficiency Fibertex nanofibre layers in the production of protective face masks, end-users can expect to reach N95 and FFP2 level of protection,,” says Per Holst Rasmussen of Fibertex Nonwovens. “The main benefit of Fibertex nanofibre layers, compared to electret meltblowns currently used in masks, is guaranteed efficiency of the filtration layer during the lifetime of the mask. Fibertex nanofibre layers are based purely on mechanical filtration, unlike electret meltblown materials, which tend to become discharged during usage and substantially lose filtration efficiency, especially in conditions of over 80 % relative humidity.

“Another important benefit of this advanced technology, is durability of the nanofibre layer, which enables extended storage time of masks, making them suitable for use as disaster and epidemic relief safety stocks.”

Fibertex synthetic nonwovens and nanofibre treated products are suitable for use in various functional layers in protective face masks and respirators. Functions include molding supports, particulate efficiency layers and barriers against viruses and bacteria and liquid penetration. Fibertex activated carbon products are highly effective in the control and absorption of odors, smoke and liquids. All products can be delivered slitted to specific end-use widths required.
