Furthermore, since the speed of ultrasonic welding is faster during thermal welding and ultrasonic welding, bonding by ultrasonic welding is more preferable.

Hereinafter, a layer of a transparent dental mask according to another embodiment of the present invention will be described in detail with reference to FIG. 4 .

The second mask body 20 includes a first film 21 made of a synthetic resin of a transparent material, and the first mask body 10 and the third mask body 20 rather than the first film 21 . It may include a second film 22 that is easy to weld with a synthetic resin by ultrasonic welding or thermal welding.

In more detail, the first film 21 is made of polyethylene terephthalate (PET) having a dense structure, and the second film is made of transparent polyethylene (PE) and transparent stretched polypropylene (PE), which are good at ultrasonic welding and heat welding ( OPP) may be provided with any one of chlorinated polypropylene (CPP).

This is when the first film 21 is made of a material that is not easy to heat and ultrasonically weld, such as polyethylene terephthalate (PET) having a dense structure, and the second film 22 laminated with the first film 21 ) may be ultrasonically welded or thermally welded to at least one of the first filter 11 and the second filter 12 .

4 is an example in which the second film 22 is laminated on both the front and rear surfaces of the first film 21 , and the rear surface of the first filter 11 is provided on the front surface of the first film 21 . is combined with the second film 22 , and the front surface of the second filter 12 is ultrasonically or thermally welded with the second film 22 provided on the rear surface of the first film 21 .

According to this embodiment, the cotton filter is composed of natural fibers and is difficult to be coupled to the second mask body 2 through ultrasonic welding and heat welding. In order to solve this problem, the first filter containing synthetic resin ( 11) and the second filter 12 may be laminated.

Meanwhile, the third filter 13 may also be provided as a melt blown filter or a nano filter, which is an electrostatic filter.

In another embodiment, the front surface of the first filter 11 may be ultrasonically or thermally welded to the rear surface of the second film 22, in which case the second filter 12 and the third filter 13 ) may be optionally provided.

An antibacterial composition may be coated on at least one of the first mask body 10, the second mask body 20, and the third mask body 30, and when antibacterial treatment is performed, the air contained in the inhaled It is possible to block all or part of bacteria or viruses, as well as prevent the problem of bacteria or fungi from multiplying as the mask is used for a long time.

The antibacterial agent treatment may be performed through a process of immersing the nonwoven fabric in an aqueous solution of an antibacterial composition and a binder.

On the other hand, the first mask body 10, the second mask body 20, and the third mask body 30 may be coated with a cooling composition, and when the cooling agent treatment is performed, the user can feel it when wearing the face. It can reduce the feeling of stuffiness and facilitate the release of body temperature.

The cooling agent treatment may also be performed by immersing the nonwoven fabric in an aqueous solution of the cooling composition and the binder.

An anti-fogging coating layer 23 may be formed on at least one of both sides of the second mask body 20, and the anti-fog coating layer 23 is provided with a hydrophilic coating to form a flat dew condensation to increase the transmittance can

Conversely, the anti-fogging coating layer 23 may be provided as a water-repellent coating, which induces dew condensation to form close to a spherical shape so as to fall downward.

5 shows that a plurality of anti-fog holes 24 are formed in the second mask body 20 .

Specifically, a plurality of anti-fog holes 24 passing through the front and rear may be formed in the region facing the user's lips among the second mask body 20, and water vapor is discharged to the outside through the anti-fogging hole 24 may leak.

The anti-fog may have a diameter of 0.1 to 10 micrometers, preferably 0.01 to 5 micrometers.

This is because the minimum size of droplet (saliva) particles discharged from the mouth of a person is around 5 micrometers and the water vapor particles are around 0.001 micrometers, so the water vapor particles flow smoothly, but droplet particles go inside through the anti-fog hole (24). This is to prevent easy penetration.

Here, although the minimum size of the droplet (saliva) particles is about 5 micrometers, even when the diameter of the anti-fog sphere is 10 micrometers, it is possible to block the inflow of the droplets to some extent.
