Abstract
FIELD: means of protection.
SUBSTANCE: collapsible breather, flat when folded, is made of single-component hard filtration panel joined to other part of breather at least along one separation line. Panel comprises porous single-component one-layer nonwoven fabric, which comprises charged intertwined continuous polymer fibres of one and the same polymer composition and has sufficient density or interfibrillar adhesion, so that Harley hardness is more than 200 mg, and pressure difference at breather is less than 20 mm of water column.
EFFECT: invention provides for formation of breather without additional strengthening layers, double-component fibres or other strengthening, ease of secondary processing, possibility to fold breather into flat form for storage.
