example 1
[0035] The inner textile layer of the mask 1 is made of a spun-bonded non-woven fabric, preferably polypropylene (PP), polyester (PES) or other microfibres, with a basis weight of between 12-50g / m 2 changes within the interval. On said layer are deposited materials prepared by needle-free electrospinning, such as polyvinylidene fluoride (PVDF), polyurethane (PUR), polyester (PES), polylactic acid (PLA), polycaprolactone (PCL) Nanofiber filter layer of hydrophobic polymer, according to the needs and designation of mask 1, the basis weight of the nanofiber filter layer is 0.03-1g / m 2 changes within the interval. The diameter of nanofibers reaches 150-600 nanometers. On the nanofiber filter layer there is further deposited a face mask 1 made of melt-blown nonwoven fabric preferably polypropylene (PP), viscose (VS), polyester (PES) and possibly other microfibers The outer textile layer, according to the needs and designation of the mask 1, the basic weight of the outer textile...
example 2
[0038] The inner textile layer of the mask 1 and the nanofiber filter layer deposited thereon were produced in the same way as in Example 1. Deposited on the nanofiber filter layer is an outer textile layer formed by a combination of a sub-layer made of a melt-blown non-woven fabric and a sub-layer of a spun-bonded non-woven fabric, preferably the melt-blown non-woven fabric Polypropylene (PP), polyester (PES), possibly other microfibers, the spun-bonded non-woven fabric is preferably polypropylene (PP), possibly other microfibers, and according to the needs of the mask 1 And specified, its final basic weight is 30-80g / m 2 changes within the interval. At the same time, the sublayer made of spunbonded nonwoven improves the mechanical properties of the mask 1 and protects the sublayer made of meltblown nonwoven against mechanical wear or other damage.
[0039] All layers of the mask 1 are connected to each other in the same way as in Example 1.

example 3
[0042]The outer textile layer and the nanofiber filter layer of the mask 1 were produced in the same way as in Example 1. These layers are all deposited on the inner textile layer of the mask 1 made of a hydroentangled nonwoven fabric preferably viscose (VS), cellulose or polymeric microfibres, according to the needs and specifications of the mask 1 , the basic weight of the inner textile layer is 30-80g / m 2 changes within the interval.
[0043] All layers of the mask 1 are connected to each other in the same way as in Example 1.
[0044] On the edge of the outer surface of the inner textile layer of the mask 1 is provided a layer of adhesive material with good skin compatibility.

Abstract
The invention relates to a face mask used for removing biological and mechanical impurities from breathed and / or exhaled air. The face mask comprises an inner textile layer and an outer textile layer. A filtering layer of polymer nanofibres, and / or an active layer of polymer nanofibres containing a biocidal substance(s) in the structure, are arranged between the inner textile layer and the outer textile layer. The outer textile layer and the inner textile layer are formed of microfibers. At least the outer textile layer and a neighbouring polymer nanofiber filtering layer or a neighbouring polymer nanofibreactive layer are hydrophobic. All the layers are interconnected by a net of joints, and the net of the joints can prevent mutual motion of the layers 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 a user. The method of fixing the face mask to the face secures perfect adhesion of the face mask to the skin along the entire periphery, thus preventing breathing in an unfiltered air. The invention further relates to a manufacturing method of the face mask.
Description
technical field [0001] The present invention relates to a mask for removing biological and mechanical impurities from inhaled and / or exhaled air, comprising an inner textile layer and an outer textile layer between which polymer nanofibers are arranged The filter layer and / or the active layer of polymeric nanofibers containing bactericidal substances in its structure. [0002] The invention also relates to a method for making the mask. Background technique [0003] Numerous patent documents disclose several variants of masks designed to remove biological and / or mechanical impurities from inhaled and / or exhaled air, these masks comprising at least one nanofibrous layer. [0004] The mask disclosed in CN2640523 belongs to the simplest variant of this mask, since it includes a nanofiber filter layer arranged between two fabric layers. The mask described in CN2650790 is similar in its structure, however, wherein the nanofiber layer is placed between two nonwoven fabric layers....
