Face mask and method of its production

摘要

The invention relates to a face mask for removal of biological and mechanical impurities from breathed and/or exhaled air, comprising an inner textile layer and an outer textile layer, between which there is arranged a filtering layer of polymer nanofibres and/or active layer of polymer nanofibres, which in its structure contains a biocidal substance(s). The outer as well as the inner textile layer are formed of microfibres, while at least the outer textile layer and with it neighbouring filtering or active layer of polymer nanofibres are hydrophobic, and all layers are interconnected by a net of joints, that prevent their mutual motion and reduce permeability of the face mask only minimally. The inner textile layer is on periphery of the face mask provided with a layer of an adhesive for fastening 'to the face of the user. This method of fixing the face mask to the face secures' perfect adhesion of the face mask to the skin along its entire periphery, thus preventing breathing of an unfiltered air. The invention further relates to a method for production of such face mask.
