Hereinafter, a preferred embodiment of the present invention for achieving the above object will be described with reference to FIGS. 1 to 6 with reference to the accompanying drawings.

First, the present invention constitutes the upper and lower fabrics 11 and 12 with polyester or nylon monofilament yarn, and stacks the upper and lower fabrics 11 and 12 to form a multi-layer, but the After placing a polyethylene hot melt 13 therebetween, it is compressed with a hot press to form the mask body 10 .

After that, the mask body 10 is put into a mold having a mask shape to be manufactured, and one or more folds 14 are formed so that a part of the mask body 10 can be folded, and the The mask 1 is finally formed by forming locking holes 15 penetrating through both sides of the upper part, and configuring each locking part 20 in the locking holes 15 .

First, looking at the configuration, as shown in FIGS. 1 to 3, polyester or nylon monofilament yarns having a diameter of 0.1 to 0.5 microns are woven with warp and weft yarns, and each monofilament yarn spacing is The upper and lower fabrics 11, 12 and the upper and lower fabrics 11 and 12 in the form of a mesh that are selectively configured and have a dust collection rate of 60 to 99%, and the upper and lower fabrics 11 and 12 and their shapes are formed to correspond, the upper and lower fabrics 11 and 12 The mask body 10 is formed of three layers composed of a radial polyethylene (Polyethylene) hot melt fabric 13 formed between the lower fabrics 11 and 12. At this time, on the upper portion of the mask body 10 One or more folding parts 14 are formed, and one or more locking holes 15 are formed at positions spaced apart from the folded parts 14 on both sides of the upper side, so that each locking part 20 is attached to the locking hole 15. connection will be established.

On the other hand, polyester monofilament yarn has strong tensile strength, has little tendency to increase electrical resistance, has a low rate of change of size due to water absorption, has excellent heat resistance and chemical resistance, and has excellent formability at 255° to 265°. It is excellent, dye does not come off easily, and it is known for use in the production of zippers, electric wire coverings, seat belts, conveyor belts, industrial (for road pavement), shoes, bag linings, and canvas (filters).

In addition, nylon monofilament yarn has high tensile strength and high melting point compared to other resins, so it has excellent heat resistance, is tough and flexible in a high temperature range, has a small friction coefficient and has excellent wear resistance, so it has self-lubrication and self-extinguishing properties. It is known to be easily flame retardant.

The upper and lower fabrics 10 and 20 in the form of a mesh can be selectively formed by using a polyester monofilament yarn or a nylon monofilament yarn having the above-described characteristics.

In the case of the upper and lower fabrics 11 and 12 of the present invention, by having flexibility, there is an effect of being able to respond flexibly from bending or the like.

At this time, when weaving the polyester monofilament yarn or nylon monofilament yarn, the number is configured differently according to the size of the hot malt 13 , and the size of the hot malt 13 is the standard As a result, the fractionation and collection rate is determined according to the number of arrangements.

That is, when weaving the polyester monofilament yarn or nylon monofilament yarn with warp and weft yarns, the number of batches is determined based on the size of the hot melt 13, so that the polyester (Polyester) monofilament yarn ) As the distance between monofilament yarns or nylon monofilament yarns varies, the dust collection rate is determined according to the size of the gap formed therebetween.

Here, the polyester (Polyester) monofilament yarn or the nylon (nylon) monofilament yarn may contain carbon or copper alone or both.

Polyester monofilament yarn Nylon monofilament yarn Polyester monofilament yarn + carbon Nylon monofilament yarn + carbon Polyester monofilament yarn + copper Nylon monofilament yarn + copper Polyester monofilament yarn + carbon + copper Nylon monofilament yarn + carbon + copper

As shown in Table 1 above, in the present invention, when configuring the upper and lower fabrics 11 and 12, the materials can be selectively selected individually or by selectively mixing them.

At this time, the carbon forms a monofilament yarn by mixing carbon powder or carbon liquid with polyester when constituting the first monofilament yarn, and weaving the monofilament yarn with warp and weft yarns, and finally phase, It is possible to form the lower fabric (11, 12).

In other words, it is possible to configure the monofilament yarn by individually or selectively mixing carbon or copper with the polyester monofilament yarn or nylon monofilament yarn as the basis.

By containing carbon and copper in these upper and lower fabrics 11 and 12, it is possible to have antibacterial, antistatic, and deodorizing effects, so that when using a mask that serves as a final filter at the same time, it is possible to have freshness. In addition, especially when applied to a mask, it is possible to create a comfortable environment and fundamentally block the inflow of other foreign substances into the respiratory system.

In addition, as described above, the upper and lower fabrics 11 and 12 have excellent heat resistance so that they can respond flexibly to bending, etc. Unlike the mask, it is possible to have antibacterial, deodorizing and antistatic effects without performing any work such as separate coating on the upper and lower fabrics 11 and 12. It is possible to completely compensate for the failure to achieve the original purpose of the mask due to the falling or damage of the coating part.

In addition, since the upper and lower fabrics 11 and 12 are not formed only of a simple synthetic resin material, frictional force on the user's face is minimized, thereby providing comfort.

On the other hand, the reason why the polyester (Polyester) monofilament yarn or nylon (nylon) monofilament yarn is formed to have a diameter of 0.1 to 0.5 microns is to increase the dust collection rate, which is the most important object of the present invention. In order to finely control the gap formed between the filament yarns, it is preferable to have the above diameter, and the mask should be light. be able to do

On the other hand, the polyethylene (Polyethylene) hot-melt fabric 13 comprised between the upper and lower fabrics 11 and 12 in the form of a mesh woven using the monofilament yarn as described above is substantially the upper and lower fabrics 11 , 12) for bonding, and is formed in a radial shape.

At this time, the polyethylene (Polyethylene) hot melt fabric 13 is formed in a weight of 10 to 50 g, and the weight is usually determined by the size of the polyethylene (Polyethylene) hot melt fabric, so that the weight is described and expressed. .

In addition, as the polyethylene hot-melt fabric 13 is radially formed, when the upper and lower fabrics 11 and 12 are woven to form a mesh shape, a fine gap is formed therebetween. At this time, the polyethylene (Polyethylene) hot-melt fabric 13 is disposed between the upper and lower fabrics 11 and 12 and compressed by heat press to close the gap, thereby further increasing the dust collection efficiency. .

In addition, according to the present invention, as shown in FIG. 4, one or more of the hot-melt fabric 13 and the upper and lower fabrics 11 and 12 are sequentially arranged under the upper and lower fabrics 11 and 12 according to use. Even if there are some defects in overall durability and manufacturing, it is possible to configure more than 5 layers, thereby maximizing the effect.

Here, in the mask body 10 configured as described above, as shown in FIG. 5 , one or more folded portions 14 are formed on the upper part, and one or more locking holes 15 are formed on both sides of the upper part, and then the locking part 14 is formed. The mask 1 is formed by connecting each locking part 20 to the hole 15 .

At this time, in the case of the folded portion 14, after putting it in a mold having the shape of the mask to be manufactured, the folded portion 14 is selectively formed, thereby permanently forming the folded portion 14, so that the user At the same time, it can be easily worn, and can be closely attached to and sealed to the user's face by the folding part 14, and the locking hole 15 is formed by applying a conventional punching machine or other conventional method to the locking hole 15. can be formed.

In addition, it is preferable that the locking part 20 configured to be hooked on the locking hole 15 is made of a material having a tensile force, so that the locking part 20 can be stretched according to the user.

Here, as shown in FIG. 6 , the central portion of the locking part 20 comes into contact with the user's ear, at this time, a portion of the user's ear may be peeled off or blistered due to frequent friction of the user's ear. Problems such as grabbing occurred frequently.

In order to compensate for this problem, it is possible to provide convenience in use by configuring the protective member 21 such as a sponge having a relatively low frictional force and a soft material.

In addition, in the case of the protective member 21, it can be integrally formed with the locking part 20, and if necessary, one side of the protective member 21 is cut so that the locking part 20 is inserted into the locking hole. After the configuration in (15), it may be configured to be wrapped by being inserted into the outer periphery of the locking part 20 .

In addition, the protective member 21 may be formed of one or more, and may be used according to the user's situation.

The mask of the present invention configured as described above is configured such that the upper and lower fabrics 11 and 12 and the hot melt fabric 13 are laminated, and the mask body 10 that simultaneously performs the filter role is configured, There is an effect that can provide convenience in manufacturing that does not need to configure the inner, outer skin or filter, respectively.

According to the multilayer mask and manufacturing method with improved dust collection efficiency of the present invention, while maintaining the original purpose of the mask, it does not require separate inner and outer fabrics, and is easy to use by constructing locking parts on both sides of the mask body As it is possible, it provides convenience in use, while carbon and copper contain antibacterial effect, deodorization effect, and antistatic effect. Above all, separate coatings on the inside and outside of the mask It is a useful invention that can be used for a long period of time because it does not require the same operation, so that when it comes into contact with users' skin, skin trouble does not occur, and it can have flexibility from bending during washing.
