Description

Mask having antibiotic and deodorization function and manufacturing method thereof

The present invention relates to a mask and a method for manufacturing the same, and in particular, by placing an antibacterial and deodorizing fabric woven with copper between the inner and outer skin fabrics constituting the mask and fusion and cutting to have a mask shape, to have antibacterial and deodorizing functions Of course, it relates to a mask having an antibacterial and deodorizing function enabling repeated reuse, and a method for manufacturing the same.

Due to the recent epidemic of viruses spread through droplets, wearing a quarantine mask has become very important, and wearing such a quarantine mask is proving to be a very effective means to block the spread of the virus.

In Republic of Korea Utility Model Publication No. 20-2009-0010285 (Prior Art 1), a plurality of filter papers are laminated and then Thomson (die cutting) operation is performed to form a nose cover and a chin support on the upper and lower sides of the mask body, followed by ultrasonic welding. A mask was proposed to increase the anti-vibration effect by attaching it to the wearer's nose and chin.

In the case of the prior art 1, dust such as dust and fine dust can be simply filtered by filter paper, but since it cannot effectively block micro-sized viruses smaller than this, there is a limit to use as a quarantine mask.

Therefore, in Republic of Korea Utility Model Registration No. 20-0278590 (Prior Art 2), an electrostatic filter layer is inserted between the filter papers made of non-woven fabric to adsorb dust, fine dust, viruses, etc. by static electricity to supply safe air to the wearer. do.

However, when the static electricity applied to the electrostatic filter layer is lost, the filtering effect of the mask according to the prior art 2 is significantly lowered, so it is mostly used for one-time use, which is a great economic burden, and also, when worn for a long time, The wearer's droplets continue to contaminate the inner part of the mask, resulting in an unpleasant odor.

In addition, the electrostatic filter forming the electrostatic filter layer typically uses a MB (melt blown) filter made of polypropylene as a raw material. Since the thickness of the MB filter is about 800 nm, the nano-sized MB filter is separated from the nano-unit MB filter. As particles pass through the filter paper and enter the wearer's respiratory tract, there is also a problem that may cause respiratory diseases.

In order to solve this problem, the present invention provides a mask having an antibacterial and deodorizing function that enables repeated reuse by placing an antibacterial and deodorizing fabric woven with copper between the filter paper fabrics, laminating them, and processing them into a mask shape, and An object of the present invention is to provide a method for manufacturing the same.

The mask having an antibacterial and deodorizing function of the present invention for achieving the above object is characterized in that the antibacterial and deodorizing fabric woven containing copper is laminated and laminated between the filter fabrics on which at least two or more layers are stacked. .

In addition, the antibacterial and deodorizing fabric is fused and laminated to have a plurality of cells in any one filter fabric.

And, the mask manufacturing method having an antibacterial and deodorizing function of the present invention,

A first process of feeding the filter fabric and stacking the antibacterial and deodorizing fabric woven with copper in a state in which no tension is applied;

a second process of laminating the stacked filter fabric and antibacterial and deodorizing fabric by fusion to have a plurality of cells;

A third process of fusion and cutting the raw fabric to which the filter fabric and the antibacterial and deodorizing fabric are fused, and another filter fabric from each roll to have a shape of a mask.

In addition, a fusion line is formed along the edge portions of the plurality of cells to isolate each cell.

In addition, in the antibacterial and deodorizing fabric, copper weft yarns are arranged at regular intervals, and synthetic resin warp yarns are arranged at regular intervals so that the weft yarns and warp yarns are woven.

According to the present invention as described above, the antibacterial and deodorizing fabric containing copper is located between the filter fabrics constituting the mask, so that it has antibacterial and deodorizing functions, and the antibacterial and deodorizing power is continuously maintained by the copper component even after repeated use. Because it can be maintained, there is a very advantageous advantage in terms of hygiene and economy.

In addition, it has excellent antibacterial and sterilization effects by capturing and sterilizing bacteria or viruses, which are foreign substances in the cell, and isolates the foreign substances collected in the cell from spreading to neighboring cells, thereby preventing the spread of contamination in the mask. There is this.

The above-described objects, features and advantages will be described below in detail with reference to the accompanying drawings, and accordingly, those of ordinary skill in the art to which the present invention pertains will be able to easily implement the technical idea of the present invention.

In describing the present invention, if it is determined that a detailed description of a known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

The terms used in the present invention have been selected as currently widely used general terms as possible while considering the functions in the present invention, but these may vary depending on the intention or precedent of a person skilled in the art, the emergence of new technology, and the like.

In addition, in a specific case, there is a term arbitrarily selected by the applicant, and in this case, the meaning will be described in detail in the description of the corresponding invention.

Therefore, the term used in the present invention should be defined based on the meaning of the term and the overall content of the present invention, rather than the name of a simple term.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, the embodiments of the present invention illustrated below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below.

The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art.

First, in the present invention, a known mask manufacturing apparatus can be used to manufacture a mask. As an example, as in Korean Patent Registration No. 10-0783311, a mask filter fabric supply roller for supplying one or more raw fabrics; , a pattern forming roller that forms and laminates patterns on the surface of the mask filter paper supplied by the cloth supply roller through ultrasonic vibration, and the mask filter paper fabric with the pattern formed by the pattern forming roller in the shape of the upper and lower filter paper of the mask It consists of a first cutting roller that cuts with a razor, and a second cutting roller that receives the upper and lower filter paper cut by the first cutting roller and the fabric for the front filter paper supplied separately at the same time, combines them with each other and cuts them in the form of a mask by ultrasonic waves can be

That is, as shown in FIG. 1, while feeding the two filter fabrics 10, the first ultrasonic welding is performed by the laminating roller 20 and the ultrasonic horn, and then the lamination is performed, and then cut in the form of a mask by the cutting roller 30 and the ultrasonic horn. By doing so, the mask M is manufactured.

The present invention has a structure in which an antibacterial and deodorizing fabric is laminated to one filter fabric corresponding to the outer skin of the mask, and another filter fabric corresponding to the inner skin of the mask is laminated to the laminated filter fabric and antibacterial deodorizing fabric. do.

To explain this, first, as shown in FIG. 2, the antibacterial and deodorizing fabric 110 is laminated on the upper side of the first filter fabric 100 made of a synthetic resin material such as nonwoven fabric, PE, nylon, etc. and then laminated by fusion. At this time, ultrasonic welding, thermal welding, high-frequency welding, etc. may be used as a means for welding, and the following describes a process of laminating using ultrasonic welding as an example.

In the antibacterial and deodorizing fabric 110, weft yarns are arranged at regular intervals in the horizontal direction as shown in FIG. 3, and warp yarns are arranged at regular intervals in the vertical direction, and the weft yarns are mainly arranged in verbs. The yarns made of synthetic resin materials such as PE, PP, and PC are mainly arranged for the warp.

For example, in the weft yarn, only the verb is arranged, or the verb and the yarn made of a synthetic resin material may be alternately arranged. can

This is to make it easier to weave while maintaining antibacterial, sterilizing and deodorizing power due to the company's copper component. If the warp and the warp are arranged only with the weft, the copper particles of the weft and the warp placed in the warp are separated by friction with each other, thereby reducing the sterilization power and increasing the manufacturing cost.

However, by weaving the weft so that the yarn is mainly arranged, and the warp yarn so that the synthetic resin yarn is mainly arranged, there is no friction between the wefts and copper particles are prevented from falling off.

Of course, both the weft and the warp may be manufactured only by the same company, and also, this antibacterial and deodorizing fabric 110 may be knitted in the form of a cloth.

It is preferable to use 70 denier for the above verb, and it is preferable to use 100 denier for the synthetic resin yarn made of PE material.

Here, the denier (denier) is a unit indicating the thickness of the yarn, it is 450 m in length and indicates the thickness of the yarn to have a weight of 0.05g.

Therefore, by forming the sterilizing pad layer 20 by the yarn or silver and the synthetic resin thread, it is harmless to the human body and can be manufactured relatively inexpensively.

The first filter fabric 100 and the antibacterial and deodorizing fabric 110 are fed from each winding roll and stacked. At this time, the first filter fabric 100 is mainly made of non-woven fabric, and the antibacterial and deodorizing fabric 110 is nylon. Since it is formed of a yarn made of a core material and a synthetic resin thread, the first filter fabric 100 has almost no elastic force, whereas the antibacterial and deodorizing fabric 110 has greater elasticity than the first filter fabric 100. .

Therefore, when pulling the antibacterial and deodorizing fabric 110 by feeding from the winding roll, both edge portions in the longitudinal direction are curled inward or are not flattened due to the partially applied tension, thereby causing the first filter fabric It is not possible to stack flat on the upper side of (100).

That is, since the tension of the first filter fabric 100 and the antibacterial and deodorizing fabric 110 are not the same, it is very difficult to laminate by ultrasonic fusion while simultaneously feeding from each winding roll.

Therefore, while feeding the first filter fabric 100 , the tension of the antibacterial and deodorizing fabric 110 is removed and then placed on the upper side of the first filter fabric 100 , so that the upper side of the first filter fabric 100 . It is to allow the antibacterial and deodorizing fabric 110 to be stacked flat on each other.

In order to remove the tension when the antibacterial and deodorizing fabric 110 is fed, the first filter fabric 100 wound on the first roll 200 is fed by the feeding roller 210 as shown in FIG. As the antibacterial and deodorizing fabric 110 is fed by the feeding roller 210 from the second roll 220 , it is positioned above the first filter fabric 100 .

At this time, a motor 221 is installed on the rotation shaft of the second roll 220 , and the antibacterial and deodorizing fabric 110 is tensioned by rotating the second roll 220 at the same feeding speed as the feeding speed of the feeding roller 210 . It will be fed in the removed state.

That is, the first filter fabric 100 wound on the first roll 200 is fed with tension by the feeding roller 210 , and the antibacterial and deodorizing fabric 110 wound on the second roll 220 is By feeding in a state in which the tension is removed, it is fed into the ultrasonic welding machine 230 in a flat unfolded state, and lamination is performed by fusion.

In addition, in order to remove the tension of the antibacterial and deodorizing fabric 110 in the initial stage, it is loosened from the second roll 220 so that it is fed by the feeding roller 210 and at the same time as the feeding speed of the feeding roller 210, the motor When the rotation speed of the 221 is controlled, the antibacterial and deodorizing fabric 110 is always introduced into the ultrasonic welding machine 230 in a state in which the tension is removed.

In this way, the first filter fabric 100 and the antibacterial and deodorizing fabric 110 from which the tension has been removed are put into the ultrasonic welding machine 230 in a stacked state and laminated as shown in FIGS. 5 and 6, at this time the first filter fabric 100 and the antibacterial and deodorizing fabric 110 are uniformly laminated on all sides by the ultrasonic fusion wire 120 in the form of a grid, and a plurality of cells 130 isolated on all sides by the ultrasonic fusion wire 120 are formed. do.

That is, the cell 130 has its edges all fused by the ultrasonic welding wire 120 to be isolated from the neighboring cells as in FIG. 7 , and the isolated cell 130 has a first filter cloth. A collection space (P) is formed in the non-fusion area between (100) and the antibacterial and deodorizing fabric (110).

In the present invention, the cell 130 has a lattice shape as an example, but it can have various shapes such as a circle, a triangle, and a polygon, and has a nylon core constituting the antibacterial and deodorizing fabric 110 at the time of ultrasonic welding. Since the yarn and the synthetic resin yarn are melted, the fusion with the first filter fabric 100 is very easy and strong.

In this way, the fabric in which the first filter fabric 100 and the antibacterial fabric 110 are laminated is wound on one winding roll, and the second filter made of synthetic resin material such as nonwoven fabric, PE, nylon, etc. wound on another winding roll. While being fed together with the original fabric 140, as in FIGS. 8 and 9, the second filter fabric 140 is fed and stacked on the upper surface of the antibacterial and deodorizing fabric 110, and then the mask (M) as shown in FIG. ) is ultrasonically welded along the outer shape and then cut in the form of a mask.

Therefore, as in FIG. 10 , the first filter fabric 100 laminated with the antibacterial and deodorizing fabric 110 forms the outer shell of the mask M, and the cell 130 is not formed as in FIG. 11 . The filter fabric 140 forms an endothelium so that the antibacterial and deodorizing fabric 110 is positioned between the first filter fabric 100 and the second filter fabric 140 .

Therefore, when the wearer breathes, dust, fine dust, particularly viruses pass through the first filter fabric 100 and flow into the collecting space P formed in a grid shape between the antibacterial and deodorizing fabrics 110, and the collecting space The virus trapped in (P) is killed by the antibacterial and deodorizing fabric 110 containing the copper component.

In addition, the virus trapped in the collection space (P) is trapped by the fusion line 120 formed by ultrasonic fusion, so that it cannot move to a neighboring cell, and only a specific portion of the mask (M) is contaminated.

That is, it can be more hygienic than the virus is moved and contaminated as a whole by only contamination of the part where the droplets are on the mask M, and the virus is quickly killed in the state in which it is trapped in the cell 130 .

In addition, the first filter fabric 100 and the second filter fabric 140 may be formed by stacking a plurality of filter fabrics.

As described above in detail a specific part of the content of the present invention, for those of ordinary skill in the art, it is clear that this specific description is only a preferred embodiment, and the scope of the present invention is not limited thereby. something to do.

Accordingly, it is intended that the substantial scope of the present invention be defined by the appended claims and their equivalents.
