The ear band (3) that was being gripped while losing is released.

Then, as shown in FIG. 8(e), the ear band bonding part S4 is operated to bend the ear band in a half loop to transfer and bond to the corresponding mask body 1. Then, the ear bands 3 are automatically bonded to both ends of the mask body 1. Next, when the bonding of the ear bands 3 is completed, the transfer line 10 moves one step as shown in FIG. 8(f) and the operation of bonding the ear bands 3 to the new mask body 1 is performed. Get ready to start.

As described above, the ear band supply unit of the mask manufacturing apparatus according to the present invention performs an operation of automatically bonding the ear band 3 to the mask body 1 while this operation is repeatedly performed.

On the other hand, the mask body 1 manufactured according to the present invention is made of a triple structure of an outer skin, an inner skin, and an intermediate filter member, but the outer skin and the inner skin are preferably manufactured to improve antibacterial activity and other functions.

Here, the outer shell is made of polyacrylic yarn, which is dried by immersing in a shell immersion solution consisting of 25% by weight of tourmaline powder having a particle size of 0.1 μm, 10% by weight of 2-phenylimidazole, and the remaining silicone resin. It is preferable to use.

In other words, non-woven fabric refers to a fabric made by not woven with threads. It refers to a felt-like fabric by arranging fibers (threads) in parallel or in a negative direction and bonding them with a synthetic resin adhesive.

In particular, when a melt-blown nonwoven fabric is used, ultra-fine ultra-fine fibers are stacked on the screen to provide a high level of filter performance. Therefore, the dust-proof and anti-bacterial properties are further enhanced by blocking the passage of ultra-fine dust, fungi, and microorganisms. It can be higher.

At this time, tourmaline reduces and neutralizes oxidized substances, has bacteriostatic, antibacterial, sanitizing and washing effects, and has health effects by deodorizing, hair growth, hair growth, and mineral elution, and magnesium and iron contained in tourmaline. As elements such as, boron, and silicon dissolve in water and mineralize the material, it has a good effect on the health of our body, animals and plants, and tourmaline has a synergistic effect of negative ions and far-infrared rays when the element directly contacts the skin. It can be obtained and is reported to be effective for skin diseases. In addition, 2-phenylimidazole is added to enhance quick-drying by reducing heat shrinkage when drying, and in particular, is added to increase the adhesion of the immersion liquid. In addition, silicone resin is a representative water repellent, and is added to enhance pollution prevention properties as well.

In addition, the inner skin was immersed in an inner skin immersion solution consisting of 30% by weight of rutin, 10% by weight of polyethylene glycol phenyl ether, 20% by weight of octamethylcyclotetrasiloxane, and the remaining polyacrylic resin, and then dried polyester yarn was woven It is made into fabric by non-woven immediately without ).

The endothelium thus prepared has the advantage of being able to use for a long time because it does not easily take up moisture due to breathing, and is dry in a short time, and can be used for a long time by securing quick-drying property by strongly maintaining hydrophobicity (water repellency) and preventing foreign matter adhesion to the fiber.

Here, Rutin is added to suppress inflammation upon skin contact. In addition, polyethylene glycol phenyl ether is added to prevent agglomeration between particles of the components and to ensure uniform dispersibility, so that components exhibiting waterproof and water repellent properties are evenly distributed. In addition, octamethylcyclotetrasiloxane is a waterproof organic material and is added to increase water repellency to prevent adhesion degradation and to enhance fouling resistance.

As described above, although the present invention has been illustrated and described in connection with specific embodiments, it is known in the art that various modifications and changes are possible without departing from the spirit and scope of the invention indicated by the claims. Anyone who grows up will be easy to know.
