Problems solved by technology

The structure of the 4-layer filter element formed in this way is too complicated, and the air permeability will be greatly reduced, which will lead to the formation of water mist on the inner surface of the mask, which will breed bacteria after a long time, and the production process will be more cumbersome, resulting in a greatly increased manufacturing cost. The filter element structure and the 3-layer filter element structure do not significantly improve the filtration efficiency of PM2.5

Embodiment 1

[0035] A simple mask for filtering PM2.5 with high efficiency is used as a mask with the function of filtering PM2.5. structured as figure 1 As shown, it includes a mask body used to cover the mouth and nose of the wearer, and a pair of ear hooks 4 protrude from both sides of the mask body, and a pair of ear hooks 4 are used for hooking to the wearer's ear.

[0036] The mask body is a three-layer structure forming a stacked shape, which is the outer layer of polypropylene spunbonded nonwoven fabric 1, the middle layer of ultrafine denier electret meltblown fiber nonwoven fabric 2, and the polypropylene spunbonded nonwoven fabric from outside to inside. Cloth inner layer 3, when the mask is worn, the inner layer 3 of polypropylene spunbonded nonwoven fabric faces the wearer, and the outer layer 1 of polypropylene spunbonded nonwoven fabric and the inner layer 3 of polypropylene spunbonded nonwoven fabric are evenly clothed with Breathable holes, the breathable holes run throu...

Embodiment 2

[0044] A kind of high-efficiency filter PM2.5 simple mouth mask, as shown in structure embodiment 1, difference is:

[0045] Polypropylene spunbonded non-woven outer layer 1 unit area weight is 22g / m 2 , ultra-fine denier electret melt-blown fiber nonwoven middle layer 2 unit area weight 25g / m 2 , the fineness of the fibers constituting the middle layer 2 of the ultra-fine denier electret meltblown nonwoven fabric is 0.01 denier, and the weight per unit area of ​​the inner layer 3 of the polypropylene spunbonded nonwoven fabric is 18g / m 2 .

[0046] The thickness of the inner layer of the polypropylene spunbonded nonwoven fabric is 0.2mm, the thickness of the middle layer of the ultrafine denier electret meltblown fiber nonwoven fabric is 0.1mm, and the thickness of the outer layer of the polypropylene spunbonded nonwoven fabric is 0.2mm.

[0047] In this embodiment, the preparation steps of the middle layer of the ultrafine denier electret melt-blown fiber nonwoven fabric ...

Embodiment 3

[0052] A kind of high-efficiency filter PM2.5 simple mouth mask, as shown in structure embodiment 1, the difference is;

[0053] The weight per unit area of ​​the outer layer of the polypropylene spunbonded nonwoven fabric is 28g / m 2 , the weight per unit area of ​​the middle layer of ultra-fine denier electret melt-blown fiber nonwoven fabric is 30g / m 2 , the weight per unit area of ​​the inner layer of polypropylene spunbonded non-woven fabric is 25g / m 2 , The fineness of the fibers constituting the middle layer of the ultra-fine denier electret melt-blown fiber nonwoven fabric is 0.1 denier.

Abstract

The invention relates to a simple mask for efficiently filtering PM2.5. The simple mask comprises a mask body which is used for covering the mouth and the nose of a wearer. A pair of ear hooking parts used for being hooked to the ears of the wearer is arranged on two sides of the mask body in an extending mode. The mask body is in a three-layer structure and forms a stacked shape, and the three-layer structure sequentially comprises an outer polypropylene spun-bonded non-woven layer, a middle superfine-electret melt-blown fiber non-woven layer and an inner polypropylene spun-bonded non-woven layer. When the mask is worn, the inner polypropylene spun-bonded non-woven layer faces to the wearer. Small breathing holes are respectively distributed in the outer polypropylene spun-bonded non-woven layer and the inner polypropylene spun-bonded non-woven layer and penetrate through the outer polypropylene spun-bonded non-woven layer and the inner polypropylene spun-bonded non-woven layer, and the hole diameters of the small breathing holes are 0.3-0.6mm. The invention further provides a manufacturing method of the mask. The simple mask has the characteristics of high filtering and low flow resistance and has prominent blocking and capturing capabilities for PM2.5 air particles.

Description

technical field [0001] The invention relates to the technical field of fine particle protection products, in particular to a simple mask for highly efficient filtering of PM2.5 and a manufacturing method thereof. Background technique [0002] PM2.5 refers to particulate matter in the atmosphere with an aerodynamic equivalent diameter less than or equal to 2.5 μm, also known as particulate matter that can enter the lungs. High concentrations of PM2.5 pollution affect ambient air quality and human health. With the gradual implementation of new air quality evaluation standards across the country, and the emergence of large-scale persistent haze weather in many provinces and cities in my country in recent years, "PM2.5" has become the focus of attention. Because PM2.5 particles have a great impact on ambient air quality and human health, the public has shown great enthusiasm for masks, but there are not many masks on the market that are specially designed to protect against suc...
