The present invention relates to a textile mask that can be used continuously by washing. As shown in Figure 1, it is a multi-functional mask whose main composition is a mask body 10, a filter 20, a water repellent layer 30, and a mineral body 40.

First, the mask body 10 according to the present invention is made of a fiber material that hangs on the wearer's ears and covers the mouth and nose, as shown in FIGS. 1 to 3.

This mask body 10 is composed of a mask fabric 11, a pocket fabric 12, and a finishing fabric 13.

The mask fabric 11 is formed in a square or oval shape with a size that covers at least the wearer's mouth and nose.

This mask fabric 11 may be formed of multiple fabrics as shown in an enlarged manner in FIG. 4 or a knitted fabric as shown in an enlarged manner in FIG. 5 .

The multi-fabric consists of two or more fabrics (11a) woven in the same or different patterns, stacked in multiple layers, and integrated by the finishing fabric (13).

The knitted fabric has a three-layer structure in which the surface layer (11b), the connecting layer (11c), and the back layer (11d) are integrally woven, and the border is integrated by the finishing fabric (13).

These multi-fabric and knitted fabrics have high filtration properties as the holes leading from the outside to the inside are narrowed to several branches, thereby ensuring overall safety.

Here, the fabric 11a or the surface layer 11b exposed to the outside when worn may be dyed in a predetermined color for fashionability.

Of course, the manufacturer's mark, letters, and patterns of various shapes may also be displayed on the fabric 11a or the surface layer 11b.

The pocket fabric 12 is integrated by the finishing fabric 13 in a state where it is disposed on both sides of the rear of the mask fabric 11 at intervals avoiding the mouth and nose, as shown in FIGS. 2 and 3.

That is, a pocket (10a) is provided that opens in a direction where the pocket fabrics (12) face each other, and the filter (20) can be attached and detached through this pocket (10a).

Here, the pocket fabric 12 is one in which the weft and warp threads are woven in a predetermined pattern like the fabric fabric 11a, and is preferably made of cotton fibers as it is in close contact with the wearer's face.

The finishing fabric 13 is formed in a thin, long line shape and is sewn to be wrapped around the edges of the mask fabric 11 and the pocket fabric 12 to combine them into a single piece.

This finishing fabric 13 is composed of a vertical stripe fabric 13a sewn on both edges of the mask fabric 11, and a horizontal stripe fabric 13b sewn on the upper and lower edges.

Here, the horizontal stripe fabric 13b sewn on the upper side extends a predetermined length from the mask fabric 11 toward both sides to form an earring cord 13c that is hung on the wearer's ears.

And the horizontal stripe fabric (13b) sewn on the lower side is formed with an adjustment ring (13d) sewn as a closed loop of a predetermined size on both rear edges of the mask fabric (11).

That is, pass the earring string (13c) through the adjustment ring (13d), then hang the earring string (13c) around the ear and pull it with a predetermined tension to bring the mask fabric (11) into close contact with the face.

Then, just form a knot at the portion of the earring string (13c) located on the adjustment ring (13d) to prevent it from coming off the adjustment ring (13d).

Of course, it is okay to tie a knot not only on the earring string (13c) but also on the control ring (13d).

In this way, the length of the earring string (13c) can be easily adjusted to suit the wearer's face without using a separate adjustment member through the adjustment ring (13d), thereby reducing production costs and increasing convenience of wearing.

Next, the filter 20 according to the present invention is replaceably mounted in the pocket 10a provided at the rear of the mask body 10, as shown in FIGS. 2 and 3, and filters fine dust particles flowing into the mouth and nose.

This filter 20 may be formed of non-woven fabric as shown in FIG. 2, or may be formed of fibrous fabric as shown in FIG. 3.

Non-woven fabrics are formed by flattening nano-diameter fiber strands, and fiber fabrics are made by weaving fibers of micro-diameter or smaller in a predetermined pattern.

That is, the non-woven fabric may be formed with the same or similar structure as the disposable mask, and the fiber fabric may be formed like the mask fabric 11.

Here, the filter 20 may further include materials such as silver, copper, and carbon that provide various functionalities.

In any case, it is desirable that the filter 20 has a dust collection efficiency of 80% or more and a leakage rate of 20% or less that satisfies the KF standard.

Next, the water-repellent layer 30 according to the present invention is coated on the entire surface of the mask body 10 as shown in FIG. 1 to prevent wetting from external fluid and block the wearer's droplets from being released to the outside.

This water-repellent layer 30 is formed by spraying a water-repellent solution at high pressure on the entire surface of the externally exposed fabric fabric 11a or the surface layer 11b and drying it for 12 to 24 hours.

Here, the water-repellent solution is formed by dissolving 10% by weight of polyvinylidene fluoride powder in 90% by weight of dimethylformamide.

Polyvinylidene fluoride is a fluorine-based polymer resin that, when applied to the surface of an object, forms fine nanoscale protrusions that are empty inside.

In other words, as the water droplets have a surface contact angle of more than 150° due to the protrusions, even if fluid is contacted, they are not absorbed but immediately slide and fall (discharge) to the outside.

At this time, the water-repellent solution may be applied by spraying and then further subjected to the process of dipping or spraying in ethanol heated to 70°C before the drying process.

This ethanol lowers the coagulation speed of the water-repellent solution, making fine protrusions formed on the surface more dense.

Lastly, the mineral body 40 according to the present invention emits far-infrared rays, and is impregnated throughout the mask body 10 as shown in FIG. 1 to promote health and kill bacteria.

This mineral body 40 is created by spraying the entire mask body 10 except the filter 20 at high pressure in a state in which mineral powder having a 10-50㎛ porous plate-like structure is mixed with transparent natural vegetable oil. It dries for more than an hour.

Vegetable oil increases the dispersibility of mineral powder, allowing additional adhesives such as melamine, silicone, KEPCO, agar, and acrylic to be mixed.

Mineral powder may be composed of silicon dioxide, aluminum oxide, iron oxide, quicklime, magnesium oxide, potassium peroxide, sodium oxide, titanium dioxide, phosphorus pentoxide, manganese oxide, chromium oxide, vananium pentoxide, and other impurities.

That is, the mineral powder contains 50.4% by weight of silicon dioxide, 15.4% by weight of aluminum oxide, 5.62% by weight of iron oxide, 8.74% by weight of quicklime, 2.74% by weight of magnesium oxide, 3.43% by weight of potassium peroxide, 1.19% by weight of sodium oxide, and 0.6% by weight of titanium dioxide. It is preferable to use natural mineral pumice powder composed of 0.12% by weight of phosphorus pentoxide, 0.11% by weight of manganese oxide, 0.01% by weight of chromium oxide, and 0.01% by weight of vananium pentoxide with the remainder being other impurities.

This mineral powder has a far-infrared emissivity of 0.924㎛ at 37℃, a far ^- infrared radiation energy of ^3.72

That is, the mask impregnated with the mineral body 40 radiates far-infrared rays with long wavelengths among infrared rays, thereby exerting warming, maturing, self-purifying, neutralizing, drying and moistening functions, and resonance.

Thermal action maintains the body's body temperature at an appropriate temperature, eliminates cancer cells that are vulnerable to high temperatures, and relieves muscle fatigue.

The ripening effect promotes the growth of the human body and promotes epithelial formation, shortening the healing period.

Self-cleaning action promotes smooth blood circulation within the human body and balances nutritional supply.

Neutralization neutralizes wastes and odors in the human body, and excretes wastes and harmful substances accumulated in the body through vigorous sweating along with fat.

The dry-humidity action maintains appropriate moisture in the human body, and the resonance action breaks down various nutrients in the human body to maintain balance.

Hereinafter, the test was conducted as follows to prove the efficacy of the mask according to the present invention.
