specific Embodiment approach 1

[0014] Combine below figure 1 and figure 2 Illustrate the present embodiment, it comprises mouth mask body 1, left ear strap 2 and right ear strap 3, mouth mask body 1 is made up of nano film layer 1-1, outer layer nonwoven fabric 1-2 and inner layer nonwoven fabric, The nano film layer 1-1 is attached to the outer surface of the outer non-woven fabric 1-2, and the thickness of the nano film layer 1-1 is 0.2mm. The outer layer non-woven fabric 1-2 and the inner layer non-woven fabric are fixed as a whole by punching line 5.

[0015] The nano-membrane layer is a PTFE membrane, and the PTFE membrane has a fibrillar microporous structure with a porosity of more than 85%, 1.4 billion micropores per square centimeter, and a pore diameter range of 0.02 μm-15 μm.

[0016] PTFE membrane technology has been used in clothing membranes, air filtration membranes, air purification membranes and other fields, but it has not yet been applied to the field of mask manufacturing. The fabric...

specific Embodiment approach 2

[0018] Combine below figure 1 Illustrate this embodiment, this embodiment will be further described to embodiment one, and it also comprises sticking nose bridge plastic strip 4, and described nose sticking plastic strip 4 is arranged on the mouth mask between outer layer nonwoven fabric 1-2 and inner layer nonwoven fabric On the upper edge of the body 1. The nose bridge plastic strip 4 is to make the mask body 1 stick to the nose more, so as to avoid air leakage from here.

Abstract

The invention discloses a non-medical nano-film filtering mask, and specifically relates to a mask for filtering air by using a nano-film. The mask of the invention overcomes the defects that a melt-blown cloth filtering mask in the prior art is low in use reliability and durability and poor in protection effect. The mask comprises a mask body, a left ear hanging belt and a right ear hanging belt,wherein the mask body is composed of a nano-film layer, an outer-layer non-woven fabric and an inner-layer non-woven fabric, the outer-layer non-woven fabric and the inner-layer non-woven fabric arefixed into a whole through stamping lines, the nano-film layer is attached to the outer surface of the outer-layer non-woven fabric, and the thickness of the nano-film layer is 0.2 mm. The nano-film layer is a PTFE film, wherein the porosity of the PTFE film is 85% or above, 14 billion micropores are formed in each square centimeter of the PTFE film, pore diameters are in a range of 0.02-15 microns, the PTFE film is mainly made of polytetrafluoroethylene resin, the content of the polytetrafluoroethylene resin is not lower than 90%, and the balance is impurities. The interception rate of 0.3 micron particles by the mask can reach 99% or above.

Description

technical field [0001] The invention relates to a non-medical mask, in particular to a mask using a nano-membrane to filter air. Background technique [0002] The global outbreak of the new crown virus in 2020 has caused great inconvenience to people's lives. One of them is that ordinary citizens must wear masks when going out, and this kind of anti-epidemic protection measures has become more and more normalized. Ordinary disposable masks are roughly divided into three layers. The inner surface layer and the outer surface layer are non-woven fabrics, and the middle layer is melt-blown cloth, which is used to filter the air. The melt-blown cloth is processed by the electret process to generate an electrostatic effect, which can absorb and intercept particulate matter. However, electrostatic adsorption masks have a disadvantage. After the static electricity is added, they are not always in a state of full charge saturation. In the production, packaging, delivery, transporta...
