The mask of the present invention is configured to be foldable by forming a folding portion on the center line 120 of the mask body.

The center line 120 is provided with a curved wire, and the center line 120 adheres the upper and lower sides to the bridge of the nose and the chin due to the curved wire, and is formed in a curved shape so that the mouth is spaced apart to form an internal space Breathing comfort is provided.

The bent wire may be attached to the center line 120 or provided in various ways such as sewing.

The bent wire is a component that maintains the shape of the mask body and is preferably formed of a metal or plastic material having a certain strength.

The mask body is formed of a fiber sheet 100, and the fiber sheet 100 is made of any one or a mixture of two or more of natural fibers, artificial fibers, and synthetic fibers.

The fiber sheet 100 may be preferably used as a knitted fabric.

In addition, the fiber sheet 100 is a fiber sheet having an ability to absorb moisture, and any type of fiber sheet having hydrophilicity may be used.

For example, a fiber sheet in which hydrophilic fibers such as cotton, rayon, wool, silk, etc. are contained in a fiber sheet, or a fiber sheet in which hydrophilicity is imparted through hydrophilization processing after manufacturing a fiber sheet with hydrophobic synthetic fibers may be used.

As shown in FIGS. 2 and 3, a light reflection layer 200 that reflects sunlight can be formed by applying a resin containing a metal thin film or a metal material to a part of the surface of the fiber sheet 100 forming the mask body. There will be.

The fabric containing the sunscreen may be coated with the sunscreen or fabric using yarn containing the sunscreen during the manufacturing process.

The zinc oxide and titanium oxide have high ultraviolet absorption and good infrared reflection, so they have an infrared ray blocking effect as well as ultraviolet rays.

In addition, the thin film coating layer 300 may be formed on the back surface of the fiber sheet 100 as shown in FIG. 2 on the fiber sheet 100 .

The thin film coating layer 300 is formed by coating a hydrophobic coating agent in the form of a thin film, and the thickness of the thin film coating layer 300 determines the presence or absence of the thin film coating layer 300 based on the touch and softness of the fiber sheet 100 or a human sense. It is preferable to form less than 80 nm so as not to feel it well, and it is preferable to form more than 20 nm in order to prevent peeling of the thin film coating layer 300 during washing or rubbing, and it will be preferable to form 20 to 80 nm.

Most preferably, the thin film coating layer 300 is formed on the fiber sheet 100 with a thickness of 30 to 50 nm.

The thin film coating layer 300 is formed by coating the hydrophobic coating agent, and the hydrophobic coating agent is preferably formed of a water repellent agent and a binder to have a transparent color and not to hinder the original color of the fabric.

The water repellent may be a fluorine-based water repellent agent, a silicone-based water repellent agent, a fluorine-silicone-based water repellent agent, an acrylic water repellent agent, a polyethylene-based water repellent agent, a polypropylene-based water repellent agent, a polyamide-based water repellent agent, a polyester-based water repellent agent, a polymethyl-based water repellent agent, etc., and a thin film with a nano-sized thickness. It is most preferable to use a silicone-based water repellent that is easy to form, and it will be preferable to use a silicone-based water repellent prepared by a sol-gel method using tetraethyl-orthosilicate (TEOS).

The water repellent may be used together with a solvent, a thickener, etc. to improve processability.

As the binder used in the present invention, any binder used in textile products may be used, and for example, acrylic binders, silicone binders, polyurethane binders, and the like may all be used. Among the above binders, it is preferable to use a transparent color acrylic binder that has little skin irritation and is easy to use.

The water repellent agent and the binder are mixed and used, and the mixing ratio of the water repellent agent and the binder may be adjusted according to the water repellent agent and the binder used. In general, the water repellent agent and the binder may be mixed at a weight ratio of 9:1 to 3:7.

The hydrophobic coating agent may be coated on the fiber sheet 100 by various methods such as roll printing and laminating.

The hydrophobic coating agent is applied to 70 to 95% of the surface area of one side to form the thin film coating layer 300, and the thin film coating layer 300 has a gap that is not coated with the hydrophobic coating agent of 0.5 to 5 mm.

The gap is a gap between the thin film coating layer 300 and the adjacent thin film coating layer 300, and serves as a passage for absorbing moisture from one side of the fiber sheet 100 and transferring it to the other side, and the width or length of the gap is 0.5 mm. If the width or length of the gap is greater than 5 mm, the gap through which moisture is absorbed is wide, and one side of the fiber sheet 100 may become damp due to poor moisture absorption. dryness may decrease.

The hydrophobic coating agent is a thin film coating layer ( 300) can be formed, and the width or length of the gap must be adjusted within 0.5 to 5 mm to design the pattern.

As shown in FIG. 4 , moisture generated from the body in contact with the back of the fiber sheet 100 on which the thin film coating layer 300 is formed is not absorbed due to the water repellency of the thin film coating layer 300 and is pushed into the gap. Moisture pushed into the gap is absorbed in a hydrophilic manner, and as shown in FIG. 4 , the moisture is quickly absorbed in all directions of the fiber sheet 100 .

As described above, moisture absorbed into the fiber sheet 100 is not transferred to one side of the fiber by the thin film coating layer 300, but is transferred to the other side, so that the back side of the fiber sheet 100 always feels dry.

This does not reduce the absolute moisture content of the fiber sheet 100 containing moisture, but quickly moves the moisture retained on the back side of the fiber sheet 100 on which the thin film coating layer 300 is formed to another part of the fiber sheet 100, thereby reducing moisture on one side. It will be said that there is no presence of water and the amount of moisture present is also significantly reduced.

Therefore, assuming that the amount of moisture contained in the fiber sheet 100 is the same, the retained moisture quickly diffuses to other parts of the fiber sheet 100, and the back side of the fiber sheet 100 feels dry and refreshing. And it will be possible to realize the physical property of sweat perspiration and quick drying regardless of the absolute evaporation of moisture or drying amount.

In addition, the fiber sheet 100 may contain an antibacterial and antiviral composition having a pH of 4.0 to 8.0 by containing calcium chloride, copper chloride, and iron salt in water, and having high liquid stability in which no precipitate is formed at 0 to 80 ° C. .

Hydrates of the calcium chloride and copper chloride may be used to increase water solubility.

When the calcium chloride, copper chloride, and iron salt are added below the above content range, antibacterial/antiviral performance and deodorizing function may be deteriorated. A precipitate may form in the composition.

In addition, if the content of copper chloride is high, the antibacterial/antiviral function and deodorizing function increase, but since yellowing may occur in the composition or sheet paper containing the composition, it is necessary to adjust the content according to the place of use and purpose of use. % or less will be preferred.

Chloride substances, which are the antibacterial and antiviral compositions, decompose volatile organic compounds (VOCs) and harmful substances in the air through oxidation with Mcl ₂ (M is a transition metal such as Ca, Cu, Fe, etc.), which is an active ingredient of multi metal sol, , It acts directly on harmful bacteria to break down cell membranes and interferes with the electron transport system of harmful bacteria to eliminate bacteria.

That is, the Mcl ₂ dissolves the cell membrane of harmful bacteria, acts with intracellular enzymes, blocks the metabolic function of nutrients, that is, the inflow and outflow of nutrients, and prevents the respiratory function of harmful bacteria, so that intracellular APT (adenosine triphosphate) It kills harmful bacteria by suppressing their production and destroying growth and regeneration ability.

Glycine may be further added as a buffering agent to increase reaction stability in the reaction step in the raw material mixing step.

When adding the glycine, it will be preferable to add 0.5 to 2 parts by weight to 100 parts by weight of water.

In addition, when the antibacterial/antiviral composition is prepared for textile products, a crosslinking agent may be added in the raw material mixing step to increase the bonding strength between the textile product and the composition having antibacterial/antiviral functions.

A silane-based crosslinking agent may be used as the crosslinking agent, and it is preferable to use Glycidoxy propyl trimethoxy silane.

The crosslinking agent may preferably be included in an amount of 10 to 20 parts by weight per 100 parts by weight of water.

The catalyst mixing step is a step of further adding a catalyst, a pH adjusting agent, and a metal ion sequestering agent to a composition in which raw materials are mixed.
