Description

Dust blocking composition, mask using same, and manufacturing method thereof {Dust blocking composition, dust mask using same, and manufacturing method thereof}

The present invention relates to a dust-blocking composition for preventing static electricity of an object to be coated, a mask for preventing dust from adhering to a surface to which the dust-blocking composition is applied, and a method for manufacturing the mask.

Static electricity is an electric charge whose distribution does not change with time and an electric phenomenon caused by that charge, mainly caused by friction between two types of dielectrics.

Static electricity, which is commonly experienced in the surroundings, causes discomfort such as foreign substances such as dust adhering to clothes or sparks generated when clothes made of fabrics are in close proximity to each other. there was.

As one of the technologies for solving the above problems, as disclosed in Korean Registered Patent No. 0179521 (Announcement dated April 01, 1999), in order to solve the static electricity disorder caused by friction in various natural or chemical fibers being worn An antistatic composition for clothing containing an antibacterial component has been developed.

Furthermore, there is a need for a composition that blocks dust using an antistatic agent that is harmless to the human body while being applicable to a wider range of materials, such as filter products that filter fine dust or dust masks worn on the face, as well as clothing.

In addition, in recent years, in order to prevent viral infection from carriers infected with respiratory infectious diseases, the frequency of use of dustproof or droplet blocking masks for respiratory protection is very high.

Existing consumable dustproof masks are made of non-woven fabrics with fine pores, and foreign substances such as fine dust that are larger than the pores of the non-woven fabrics in the air passing through the mask by the intake of the user wearing the mask ( Other substances entering the user's respiratory tract are filtered by the filter layer, preventing the user from inhaling fine-sized dust or droplets into the respiratory tract.

Among existing masks, as disclosed in Korean Patent Registration No. 1815757 (published on January 05, 2018), static electricity is generated in the mask to increase the filtering power, thereby inducing dust to adhere to the mask.

However, if the mask is used repeatedly or continuously, dust adhered to the outer surface of the mask during intake due to static electricity generated by friction between the face and the mask, etc. Not only fine dust floating in the air, but also fine dust previously attached to the mask were inhaled together, which quickly reduced the lifespan of the filter.

Therefore, it is necessary to prevent generation of static electricity on the outer surface of the mask so that fine dust does not adhere to the outer surface of the mask.

As disclosed in Korean Patent Publication No. 2014, 0033032 (published on March 17, 2014) for this purpose, a process capable of preventing static electricity should be further added to the existing mask manufacturing method.

According to the cosmetic ingredient hazard data of the US environmental organization EWG (The Environmental Working Group), the above compositions are composed of very low EWG grades of 1 to 2, indicating that they are made of safe ingredients with very low risk to the human body. can

Looking more closely, among the compositions mentioned above, propanediol, citric acid, and glycerin are grade 2, and all others are grade 1.

A functional dust mask 100 to which the dust blocking composition of the present invention described above is applied can be configured.

As shown in FIG. 1, a dust blocking portion 1 preventing static electricity is formed on the surface of the outer shell 2 exposed to the outside of the dust mask 100 made of multi-layered nonwoven fabric by the dust blocking composition, and the mask It is intended to prevent foreign substances such as dust from adhering to (100).

In the case of a cotton mask made of a single layer, the outer skin and the inner skin will be integrally formed without distinction, and the dust blocking portion 10 will be formed on the surface of the mask by the dust blocking composition.

Looking at the above structure in more detail, the functional mask 100 of the present invention, as shown in FIG. And the endothelium 5 is formed of a non-woven fabric to come into contact with the filter 3 to prevent the filter 3 from directly touching the user's skin, and on the contrary, the outer skin 2 in the direction of the outer surface of the filter 3 filters ( 3) in the conventional mask 100 formed to come into contact with the filter 3 to protect the dust blocking portion ( 1) was further configured.

In order to configure the dust blocking part 1 made of the above composition on the mask 100, in the manufacturing step of a general dust mask 100, a solution coating step (SS) made of a dust blocking composition for preventing static electricity is further required. It will have to be provided, and as shown in FIGS. 2 and 3, it will be examined in more detail below.

In addition, in this embodiment, the multilayer mask 100 of four layers is taken as an example, but it is obvious that the number of overlapping sheets can be varied depending on the purpose of manufacturing the mask and the type of fiber.

1. Pre-solution coating step (S01)

Among the sheets used for manufacturing the mask 100, the outer sheet 2b used as the outer shell 2 may be coated with an antistatic solution made of a dust blocking composition from the coating device 200 in advance.

Here, either of coating and spraying may be applied or overlapped, and it is irrelevant whether a separate layer is formed or permeated into fibers depending on the type of mask fiber to be coated.

This step is not the main process in which the mask 100 is manufactured, but is made in advance in the step before delivery or application of the covering roll 2a required for the process, and is wound into the covering roll 2a, and the solution before and after bonding to be described later. It can be selectively applied separately from the coating step (SS), and this step can be omitted.

2. Sheet unwinding step (S02)

Sheets made of non-woven fabric are wound and supplied in the same roll form, and this step includes preparing for unwinding.

To list, the outer skin roll 2a on which the outer sheet 2b is wound, the filter roll 3a on which the filter sheet 3b is wound, the middle skin roll 4a on which the inner layer sheet 4b is wound, and the inner layer sheet 5b. This is a step in which the wound endothelial rolls 5a are prepared, and the sheet is drawn from each roll.

Among the sheets, the outer sheet 2b may be the outer sheet 2b pre-coated with the antistatic solution in the previous pre-solution coating step (S01), or may be a step before the antistatic solution is still coated, and the latter In this case, one or more of the solution coating steps (SS) before and after the combination will be described later.

3. Clip supply step (S03)

Depending on the type of dustproof mask 100, a clip 6 for a nose pad may be further provided to adjust the curved shape of the mask 100 to fit the shape of the wearer's nose.

In this case, a process of supplying the clip 6 between the outer sheet 2b and the filter sheet 3b may be further provided, and in the case of the mask 100 without the nose pad clip 6, this step is skipped. It will be.

4. Solution coating step before combining (S04)

It is a step of coating an antistatic solution made of a dust blocking composition from the coating device 200 on one side of the outer sheet 2b of each sheet unwound in the sheet unwinding step (S02), and in the previous pre-solution coating step (S01) If the antistatic solution is coated in advance, this step can be omitted.

In addition, it is irrelevant that the solution coating step (S04) before merging may be performed before the clip supply step (S03).

The fact that the solution is coated on the outer sheet 2b before combining can prevent the antistatic solution from being applied to sheets other than the outer sheet 2b in preparation for the solution coating step (S06) after bonding to be described later.

5. Sheet merging step (S05)

The outer sheet 2b, the filter sheet 3b, the inner sheet 4b, and the inner sheet 5b drawn out in the sheet unwinding step (S02) and the clip 6 drawn out in the clip supply step (S03) are combined into one. This is an overlapping step.

In either of this step or the sheet pressing step (S07) to be described later, a process of bending and folding a specific sheet in advance according to the type and shape (for example, a bird's beak-shaped mask) of the dust mask 100 to be produced is further included. can

6. Solution coating step after combining (S06)

In the sheet combining step (S05), one side of the outer sheet 2b overlapped with another sheet is coated with an antistatic solution made of a dust blocking composition from the coating device 200.

If the previous solution coating step (S01) or the pre-combination solution coating step (S04) has not been performed, it is an essential step, and if the previous solution coating step (SS) has been performed, the solution coating step after consolidation (S06) is It can be selectively omitted or coated so that it is additionally accumulated.

7. Sheet compression step (S07)

In consideration of the sheet cutting step (S08), which will be described later, the four layers of sheets overlapped in the sheet combining step (S05) are bonded together using ultrasonic waves so that the shape of the mask 100 is fixed.

8. Sheet cutting step (S08)

The 4-ply sheet bonded in the sheet pressing step (S07) is cut to form the main body shape of the mask 100 to manufacture an individual mask 100 main body.

9. Attaching earrings (S09)

Earrings 7 (strings or bands) should be configured to be worn on the user's ears at both ends of the sheet so that the cut mask 100 body can be fixed to the user's face as the mask 100.

Therefore, the earring 7 is supplied from the earring supply unit 7a to the mask 100 body cut in the sheet cutting step (S08), and the supplied earring 7 is applied to both ends of the mask 100 body using ultrasonic waves or the like. will be combined with

10. Packaging completion step (S10)

The mask 100 completed through the earring attachment step (S09) is individually wrapped and discharged to complete the manufacture of the mask 100.

In the dust mask 100 manufactured through the above manufacturing process, since the dust blocking part 1 is coated on the surface of the mask 100 and static electricity is not generated in the mask 100, the mask 100 is worn. Even if dust in the air comes into contact with the mask during the user's inhalation, the moment the breathing stops or the exhalation during breathing causes the dust that is in contact with the mask but not attached to the mask to flow down from the mask.

The above-described mask 100 is hygienic because almost no dust adheres thereto, and at the same time, the life of the filter 3 can be prolonged, thereby increasing the lifespan of the mask 100, reducing the cost required for the mask 100, etc. It is an invention with great social and environmental benefits.

As described above, the most preferred embodiment of the present invention has been described in the detailed description of the present invention, but various modifications may be made within a range that does not depart from the technical scope of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above embodiments, but the scope of protection should be recognized from the techniques of the claims to be described later and from these techniques to equivalent technical means.
