Description

Technical Field

[0001] The present invention relates to functional clothing, and more specifically, to functional clothing capable of easily allowing air to flow into a plurality of air storage portions of clothing through an air injection device.

Background Art

[0002] Functional clothing has been developed that can form a cushioning feeling by allowing air to flow into and out of an area of the clothing for use in various applications such as knee protection pads, body shaping pads, abdominal belts / abdomen wraps, life jackets, rubber tubes, and wrist protection pads.

[0003] Conventional functional clothing has been manufactured by a method of incorporating a separate air tube that can expand as air is injected into the clothing. However, such a conventional method cannot inject air over the entire clothing or a wide area using a single tube. For this reason, when a large number of air tubes are incorporated into the clothing, there is a problem that the user is forced to go through a complicated process of separately flowing air into each air tube.

[0004] In addition, the method of incorporating a separate air tube into the clothing has a problem that the manufacturing process is complicated, and since the clothing and the air tube are formed from different materials, it gives the user a foreign body sensation and the wearing comfort is not outstanding.

[0005] On the other hand, in order to allow air to flow into such functional clothing and form a cushioning feeling, an air injection device is coupled to an area of the clothing and used.

[0006] However, conventional air injection devices have the problem that the amount of air that a user can blow in is limited, and in order to fully inflate the air tube, a great deal of force and a longer time are required of the user. In addition, a separate device such as a pump for air injection is required, which is inconvenient for the user to carry around, and when worn on clothing or the like, it gives a heavy feeling and causes inconvenience to the user.

Summary of the Invention

Problems to be Solved by the Invention

[0007] The present invention has been devised to solve the above problems, and its object is to provide functional clothing that can easily allow air to flow into a plurality of air storage portions of clothing through an air injection device.

[0008] The technical problems of the present invention are not limited to the above-described technical problems at all, and other technical problems not mentioned should be clearly understood by those skilled in the art from the following description.

Means for Solving the Problems

[0009] Functional clothing is provided according to an embodiment of the present invention. The functional clothing includes a piece of clothing formed between a first fabric and a second fabric arranged to face each other and having a plurality of air storage portions for storing air inside, and an air injection device connected to at least one of the air storage portions for injecting air into the air storage portions. Around the air storage portions, at least one first region for defining the air storage portion from another adjacent air storage portion and at least one second region for air-connecting the air storage portion to another adjacent air storage portion are formed. When air is injected into the clothing through the air injection device, the air can spread to the plurality of air storage portions through the second region.

[0010] In addition, the first region includes a film for defining the air storage portion from another adjacent air storage portion, and the film can be joined to the first fabric and the second fabric.

[0011] Furthermore, the film may have different widths for different regions of the functional clothing so that the functional clothing has air accommodation portions with different volumes for different regions.

[0012] Furthermore still, the film may be provided with air permeation means so that air can flow between the air accommodation portion and another adjacent air accommodation portion.

[0013] Furthermore still, a polymer film coating layer is formed on at least one side of at least one of the first fabric and the second fabric, and the first region may be formed by fusing at least a part of the polymer film coating layer by at least one method of heat fusion, high-frequency fusion or ultrasonic fusion.

[0014] Furthermore still, the portions of the first fabric and the second fabric that form the air accommodation portion by the polymer film coating layer may have air impermeability.

[0015] Furthermore still, the clothing may be provided with a pocket portion on the inner side where the air injection device is detachably mounted.

[0016] Furthermore still, the functional clothing further includes a discharge portion including a discharge port that is connected to at least one of the air accommodation portions and discharges the air accommodated in the clothing to the outside of the clothing, and a plug that opens and closes the discharge port. When the plug is opened, the air accommodated in the plurality of air accommodation portions can spread to the discharge port through the second region.

[0017] Furthermore, the air injection device is coupled to an area of the garment and includes a connection portion that communicates with at least one of the air storage portions to inject air into the garment, a main body portion having one end coupled to the connection portion and at least temporarily storing air, and an air inlet portion formed by opening the other end of the main body portion to allow air to flow into the inside of the main body portion. The main body portion is made of a soft material, and when the user presses the main body portion, the volume of the main body portion decreases, and the air stored in the main body portion can be distributed to the air storage portions through the connection portion.

[0018] Furthermore, the volume of the main body portion can decrease as the user holds the other end and winds at least a part of the main body portion toward the connection portion.

[0019] Furthermore, a converging portion can be formed in an area of the main body portion, such that the internal area gradually decreases from the air inlet portion toward the connection portion, guiding the air stored in the main body portion to move toward the connection portion.

[0020] Furthermore, the main body portion can be formed to store air inside by joining at least a part around a third fabric and a fourth fabric arranged to face each other.

[0021] Furthermore, a polymer film coating layer having air impermeability can be formed on at least one side of at least one of the third fabric and the fourth fabric.

[0022] Furthermore, at least one gripping portion protruding upward from at least one area of the other end is formed on the main body portion, and the user can open the air inlet portion by gripping the gripping portion and separating the third fabric from the fourth fabric.

[0023] Furthermore, the gripping portion includes a first gripping portion provided on the third fabric and a second gripping portion provided on the fourth fabric, and the first gripping portion and the second gripping portion can be respectively formed at opposite ends in the width direction of the main body portion so as to correspond to each other.

Advantages of the Invention

[0024] According to the present invention, a large number of air accommodation portions that are in air communication with each other are formed in the clothing. Even if air is injected into one air accommodation portion via an air injection device, the air can spread to all of the respective air accommodation portions, thereby improving the usability for the user.

[0025] Also, according to the present invention, a polymer film coating layer is formed on the inner surface of the fabric constituting the clothing, and a plurality of air accommodation portions that are in air communication are easily formed by using a method of fusing the fabric by at least one of heat fusion, high-frequency fusion, or ultrasonic fusion.

[0026] Also, according to the present invention, by applying a functional fabric in which a polymer film coating layer is integrally laminated, it is possible to provide functional clothing that has not only water repellency and waterproofness but also a windproof function.

[0027] Furthermore, according to the present invention, since there is no need to separately incorporate an air tube into the clothing, the manufacturing process is simple, and it is possible to eliminate the foreign body sensation associated with the incorporation of an air tube made of a material different from that of the clothing.

[0028] Furthermore, according to the present invention, an air injection device can be formed using the fabric, and air can be injected by a simple method in which the user blows air inside the fabric and then rolls and compresses it, thereby improving the usability for the user.

[0029] Furthermore, according to the present invention, even if the user blows air into the air injection device with a small force and a small number of times, the clothing can be inflated to the maximum more quickly.

[0030] In addition to these, according to the present invention, even without removing the air injection device from the clothing, it can be carried conveniently inside the pocket with a reduced volume.

[0037] Figures 1 to 3 show the functional clothing according to an embodiment of the present invention, and Figure 4 shows the air injection device according to an embodiment of the present invention.

[0038] Referring to Figures 1 to 4, the functional clothing 1000 may comprise a garment 100, an air injection device 200, and a discharge unit 300.

[0039] The garment 100 can be formed in the form of an upper garment or a lower garment that can be worn by a user using a plurality of fabrics. However, the present invention is not limited thereto, and can cover any form of clothing or accessory constituted by fabrics.

[0040] The garment 100 may comprise a plurality of air storage parts 110 for storing air inside. For example, the garment 100 may comprise a first fabric and a second fabric arranged to face each other in at least one area, and the air storage part 110 may be formed between such a first fabric and a second fabric. The air storage part 110 is capable of allowing air to flow in through the air injection device 200, can form a cushioning feeling in one area of the garment 100, and can also perform a heat retention function.

[0041] In the embodiment, the air storage parts 110 may be formed in all areas of the garment 100. However, the present invention is not limited thereto, and may be formed in some areas necessary for joint parts, shock absorption, posture maintenance, or heat retention.

[0042] In an embodiment, a polymer film coating layer 400 having air impermeability may be formed on at least one region of the first fabric and / or the second fabric. Thereby, the first fabric and the second fabric can perform a shielding function such as preventing the air in the air accommodation portion 110 from flowing out to the outside and preventing the user from being exposed to external moisture, water vapor, wind, etc. Specific details regarding the polymer film coating layer 400 will be described later to avoid redundant explanations.

[0043] Around the air accommodation portion 110, at least one first region 111 formed by joining the first fabric and the second fabric to each other and at least one second region 112 formed without joining the first fabric and the second fabric to each other may be formed.

[0044] The first region 111 can define the air accommodation portion 110 from other air accommodation portions 110. As shown in the example of FIG. 7a, polymer film coating layers 400 are formed on one side of the first fabric and the second fabric facing each other, and the first region 111 may be formed by fusing at least one region of the first fabric and the second fabric to each other by at least one of heat fusion, high-frequency fusion, or ultrasonic fusion. That is, when the first fabric and the second fabric are heated and pressed, the polymer film coating layer 400 is melted while the first fabric and the second fabric are joined to each other, whereby the first region 111 can be formed. However, the present invention is not limited thereto, and various modifications are possible, such as the polymer film coating layer 400 being formed only on one side of either the first fabric or the second fabric. The above-described fusion methods are merely examples, and this disclosure is not limited thereto. Also, for example, the plurality of first regions 111 may be formed to have a certain length and arranged at a certain interval from each other, but the present invention is not limited thereto and can have various intervals or lengths.

[0045] In another embodiment, as illustrated in FIG. 7b, the first region 111 may be composed of a film 1111 for defining the air accommodation part 110 from other air accommodation parts 110. For example, a polymer film coating layer 400 is formed on one side of the first fabric and the second fabric facing each other, and the first region 111 may be formed by fusing the film 1111 to at least one region of the first fabric and the second fabric by at least one of heat fusion, high-frequency fusion, or ultrasonic fusion. Further, the film 1111 may be joined to the first fabric and the second fabric using an adhesive, or may be adhered by any other adhesion means. In another embodiment, the first region 111 that defines the air accommodation part by the film 1111 may expand to increase the air accommodation capacity of the air accommodation part 110.

[0046] As illustrated in FIGS. 8a, 8b, and 8c, the film 1111 constituting the first region 111 may include air permeation means 1112 and 1113 that allow air to flow between the air accommodation parts 110. FIGS. 8a, 8b, and 8c are exemplary diagrams showing in detail a portion of the film in FIG. 7b (the portion of the dotted circle in FIG. 7b). The film 1111 may be composed of a porous material through which air can pass. With the air permeation means 1112 and 1113 illustrated in FIGS. 8b and 8c, air will flow between the air accommodation parts 110, enabling the air accommodation parts 110 to uniformly accommodate air, better maintaining the shape of the clothing, and allowing the wearer to move more freely. The air permeation means 1112 and 1113 may be configured, for example, as in reference numeral 1112, such that there are regions where the film does not exist, or as in reference numeral 1113, such that the film 1111 has holes 1113 through which air can pass.

[0047] The width of the film 1111 that constitutes the thickness of the first region 111 may vary according to the region of the clothing. For example, depending on the width of the film of the film 1111, the volume of the air-containing portion composed of the first fabric, the second fabric, and the film 1111 may be different. For example, when the width of the film 1111 is relatively wide, the volume of the air-containing portion 110 composed of the first fabric, the second fabric, and the film 1111 becomes relatively large, and as a result, it is possible to have a higher heat retention and cushioning feeling. For example, when the width of the film 1111 is relatively narrow, the volume of the air-containing portion 110 composed of the first fabric, the second fabric, and the film 1111 becomes relatively small, and as a result, it is possible to increase the ease of movement of the wearer. For example, in the case of the clothing 1000 where a higher heat retention is required and the movement by the wearer is small, the first region 111 may be constituted by the film 1111 having a relatively thick thickness, and in the region related to the ease of movement of the wearer such as the joint portion of the wearer, the first region 111 may be constituted by the film 1111 having a relatively thin thickness. The overall thickness of the film 1111 may be set according to the heat retention targeted by the clothing 1000.

[0048] The second region 112 can allow the air-containing portion 110 to communicate with another adjacent air-containing portion 110. For example, the second region 112 may be formed between at least a part of the plurality of first regions 111. If air is injected into the clothing 100 through the air injection device 200, the air can sequentially or simultaneously spread to the plurality of air-containing portions 110 through the second region 112. For example, the air injected from the air injection device 200 into the first air-containing portion spreads to at least one second air-containing portion formed adjacent to the first air-containing portion so as to communicate with the first air-containing portion through the second region 112, and then spreads to at least one next adjacent third air-containing portion, and in this way, it can sequentially or simultaneously spread to the plurality of air-containing portions 110.

[0049] The garment 100 may be provided with a pocket portion 120 in which the air injection device 200 is mounted on the inner side. For example, by joining at least a part of the periphery of a separate piece of fabric added to one side of the garment 100, a pocket portion 120 with an accommodation space can be formed on the inner side. The upper end of the pocket portion 120 forms an open area, and the air injection device 200 accommodated inside can be exposed above the open area. Also, when the air injection device 200 is not in use, the air injection device 200 can be stored and carried inside the pocket portion 120 in a folded state.

[0050] In an embodiment, the pocket portion 120 may be provided on the outer surface of the garment 100 as shown in FIGS. 1 and 2, but the present invention is not limited thereto, and it may be provided on the inner surface of the garment 100, or may be provided on both the outer surface and the inner surface. Also, the pocket portion 120 may be provided at the lower end of the body region of the garment 100, but the present invention is not limited thereto, and it may be provided in various regions such as the body, shoulder, or arm regions of the garment 100.

[0051] The air injection device 200 can be connected to at least one of the plurality of air storage portions 110 to inject air into the air storage portion 110 of the garment 100.

[0052] In an embodiment, the air injection device 200 may include a connection portion 210, a main body portion 220, and an air inlet portion 230.

[0053] The connection portion 210 is coupled to a region of the garment 100 (particularly, the air storage portion 110) and communicates with at least one of the plurality of air storage portions 110, thereby injecting air into the garment 100. For example, the connection portion 210 may be joined to a part of the garment 100 and integrally formed, but the present invention is not limited thereto, and it may be detachably formed with the garment 100.

[0054] The main body portion 220 is made of a plurality of fabrics and can at least temporarily accommodate air before air is injected into the garment 100 through the connecting portion 210. For this purpose, one end of the main body portion 220 may be connected to the connecting portion 210 and may be formed to have a volume and length sufficient to accommodate air.

[0055] In an embodiment, the main body portion 220 is composed of a third fabric and a fourth fabric arranged to face each other, and may be configured to join at least a part of the periphery of the third fabric and the fourth fabric to accommodate air inside. At this time, as a joining method, at least one of heat fusion, high-frequency fusion, or ultrasonic fusion can be used, but the present invention is not limited thereto, and any known joining method can be used.

[0056] In an embodiment, a polymer film coating layer 400 having air impermeability may be formed on at least one side of at least one of the third fabric and the fourth fabric. Thereby, it is possible to prevent the air inside the main body portion 220 from flowing out to the outside. Specific details regarding the polymer film coating layer 400 will be described later to avoid duplication.

[0057] The main body portion 220 is made of a soft material, and if the user presses the main body portion 220, the volume of the main body portion 220 can be reduced. For example, the user can press the main body portion 220 by gripping one end of the main body portion 220 and winding at least a part of the main body portion 220 toward the connecting portion 210. While the volume of the main body portion 220 is decreasing, the air accommodated in the main body portion 220 can spread to the air accommodation portion 110 through the connecting portion 210. As described above, the air that has spread to the air accommodation portion 110 can spread to each of the plurality of air accommodation portions 110 through the second region 112.

[0058] For example, the air injection device 200 (i.e., the main body 220) attached to the garment 100 can be wound up and stored in the garment 100 (particularly, the pocket part 120) in a state where the volume is reduced. Thereby, the user can easily carry it in a small volume and size without removing the air injection device 200 from the garment 100, can use it regardless of location and time, and can achieve good usability along with portability.

[0059] In one area of the main body 220, a converging part 221 may be formed to guide the air accommodated in the main body 220 to move toward the connecting part 210. For this purpose, the converging part 221 may be formed in a shape in which the internal area or width gradually decreases as it advances from the air inlet part 230 toward the connecting part 210. Thereby, as the air accommodated in the main body 220 advances from the air inlet part 230 toward the connecting part 210, it can be made to be more densely packed, so that air can be injected into the garment 100 more efficiently through the connecting part 210.

[0060] At one end of the main body 220 (particularly, one end where the air injection part 230 is formed), at least one gripping part 222 protruding upward from at least one area may be formed. The user can open the air inlet part 230 by gripping the gripping part 222 and separating the third fabric and the fourth fabric. For example, the gripping part 222 may be formed on both the third fabric and the fourth fabric, but the present invention is not limited thereto, and it may be formed on only one of the third fabric and the fourth fabric. Also, for example, the gripping part 222 may be formed only in one area at one end of the main body 220, or may be formed over the entire area at one end of the main body 220, but the present invention is not limited thereto, and it can cover any shape that protrudes upward enough for the user to grip.

[0061] In an embodiment, the gripping part 222 may include a first gripping part 222' provided on the third fabric and a second gripping part 222" provided on the fourth fabric. The first gripping part 222' and the second gripping part 222" may be respectively formed at opposite ends in the width direction of the main body part 220 so as to correspond to each other. Thereby, the user can more easily separate the third fabric and the fourth fabric by gripping the first gripping part 222' and the second gripping part 222" respectively.

[0062] In an embodiment, a first gripping part 222' is formed in an area at one end of the third fabric of the main body part 220, but a first opening part may be formed in another area at the one end. Correspondingly, a second gripping part 222" is formed in an area at one end of the fourth fabric of the main body part 220, but a second opening part may be formed in another area at the one end. For example, the first opening part and the second opening part may be formed by configuring one end of each of the third fabric and the fourth fabric to protrude slightly more upward than the first gripping part 222' and the second gripping part 222". Thereby, the first gripping part 222' is exposed on the fourth fabric side by the second opening part, and the second gripping part 222" is exposed on the third fabric side by the first opening part, and the user can more easily grip the first gripping part 222' and the second gripping part 222" to open the air inlet part 230.

[0063] In an embodiment, in an area of the main body part 220, an extension part may be formed to guide external air to move inside the main body part 220 when opening the air inlet part 230. For this purpose, the extension part may be formed in a shape in which the internal area or width becomes wider as it advances from the connecting part 210 toward the air inlet part 230. Before opening the air inlet part 230, since no air is accommodated inside the main body part 220, when opening the air inlet part 230 in a low-pressure state, external air can instantaneously flow into the inside of the main body part 220 having a relatively low pressure. At this time, the extension part can guide a larger amount of external air to the increasing opening area of the main body part 220.

[0064] Also, when the user blows air into the main body 220 through the air inlet 230, together with the air blown in by the user, the external air is guided inside the main body 220, and even if the user blows air with a small force and a small number of times, the volume of the main body 220 can increase rapidly.

[0065] The air inlet 230 is formed by opening one end of the main body 220 opposite to the other end connection part 210, and air can flow into the inside of the main body 220. For example, the air inlet 230 may be formed by completely opening the other end of the main body 220, but the present invention is not limited thereto, and only a region of the other end of the main body 220 may be opened to form it.

[0066] The discharge part 300 is connected to at least one of the plurality of air storage parts 110, and can discharge the air stored in the air storage part 110 of the clothing 100 to the outside.

[0067] In an embodiment, the discharge part 300 may include a discharge port and a plug. The discharge port is connected to a region of the clothing 100 (particularly, the air storage part 110), and can discharge the air stored in the clothing 100 from the clothing 100 to the outside.

[0068] The plug can open and close the discharge port. For example, if the plug shields the discharge port, the air leaking to the outside can be minimized while injecting air into the clothing 100 through the air injection device 200, and the air can be injected more efficiently. Also, after injecting the air, it is possible to prevent the air stored in the clothing 100 from flowing out to the outside and seal it.

[0069] On one hand, if the plug is opened to open the discharge port, the air contained in the clothing 100 can be discharged to the outside. That is, by opening the discharge port and pressing at least one area of the clothing 100, the air contained in the plurality of air storage portions 110 can be sequentially or simultaneously spread through the second area 112 and discharged to the outside through the discharge port.

[0070] FIG. 5 is a cross-sectional view of a polymer film coating layer 400 formed on the fabric of the clothing and the air injection device according to an embodiment of the present invention.

[0071] Here, the fabric may be at least one of the first fabric to the fourth fabric described above with reference to FIGS. 1 to 4.

[0072] Referring to FIG. 5, the polymer film coating layer 400 is formed by laminating a thermoplastic polymer film 420 on one side of a base fabric 410, and may include the base fabric 410, the thermoplastic polymer film 420, and an adhesive 430 formed therebetween.

[0073] In an embodiment, the polymer film coating layers 400 may be formed such that they face each other on both the first fabric and the second fabric (or the third fabric and the fourth fabric). In this case, by laminating the polymer film coating layers 400, a sealed space can be formed inside, or a functional material can be shielded so as not to be exposed to external moisture or water vapor.

[0074] The base fabric 410 refers to a fabric that is a raw material for clothing, and may be, for example, a woven fabric made by weaving natural fibers and / or artificial fibers.

[0075] The thermoplastic polymer film 420 may refer to a film composed of a polymer having thermoplastic properties that can be melted or deformed in shape by heating. In an embodiment, by removing the space through which moisture and air can permeate with the thermoplastic polymer film 420, the polymer film coating layer 400 can have waterproof and windproof functions.

[0076] The thermoplastic polymer film 420 may be composed of at least one of, for example, polyurethane (PU), thermoplastic polyurethane (TPU), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), linear low density polyethylene (LLDPE), polyimide (PI), polycarbonate (PC), acrylic resin, and polystyrene (PS), or a combination thereof. Preferably, it may be made of at least one of polyurethane (PU), polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). However, the present invention is not limited thereto.

[0077] In an embodiment, the thermoplastic polymer film 420 may have a thickness in the range of 20 μm to 200 μm, and preferably may be formed with a thickness of 40 μm to 100 μm. However, the present invention is not limited thereto. When the thickness of the thermoplastic polymer film 420 is less than 20 μm, problems such as a decrease in the windproof or waterproof function or a decrease in processability such as bonding between the polymer film coating layers may occur. When the thickness of the thermoplastic polymer film 420 exceeds 200 μm, there is a possibility that the activity during clothing production may decrease.

[0078] Also, in an embodiment, the thermoplastic polymer film 420 may be configured to have a hardness in the range of Shore 80A to 95A, and preferably may be configured to have a hardness of Shore 85A to Shore 90A. However, the present invention is not limited thereto.

[0079] Also, in an embodiment, the thermoplastic polymer film 420 may have a heat distortion temperature of 140°C to 200°C, preferably, may have a heat distortion temperature of 160°C to 180°C. However, the present invention is not limited thereto at all.

[0080] The adhesive 430 is coated on one side of the thermoplastic polymer film 420, and the base fabric 410 and the thermoplastic polymer film 420 can be bonded together. In an embodiment, the adhesive 430 may be a thermosetting adhesive that is cured in a certain temperature range (for example, 80°C to 90°C). The adhesive 430 may be, for example, at least one of a solvent type, a hot melt type, and a urethane type adhesive, but the present invention is not limited thereto at all.

[0081] In an embodiment, the base fabric 410 and the thermoplastic polymer film 420 can be bonded together by thermally curing the adhesive 430 between the base fabric 410 and the thermoplastic polymer film 420. At this time, the thermal curing process may be performed by a laminating process or a hot press process. Here, the laminating process means a method of heating and pressing an object while passing the object between a plurality of heating rollers. For example, by passing the laminated base fabric 410 and thermoplastic polymer film 420 between a plurality of heated heating rollers and heating and pressing, the adhesive 430 is thermally cured, and the base fabric 410 and the thermoplastic polymer film 420 can be bonded together.

[0082] FIG. 6 is a diagram showing a usage example of the functional clothing according to an embodiment of the present invention.

[0083] First, FIG. 6(a) is a diagram showing the functional clothing 1000 in a state where air is discharged from the clothing 100. When trying to let air flow into the clothing 100, the air injection device 200 stored inside the pocket portion 120 of the clothing 100 may be exposed to the outside.

[0084] Further, FIG. 6(b) is a diagram showing the functional clothing 1000 with air flowing into the clothing 100. The user can hold the gripping portion 222 of the air injection device 200 to separate the third fabric and the fourth fabric to open the air inlet portion 230, and blow air into the main body portion 220. When air is stored in the main body portion 220 and its volume increases to the maximum, the user can hold one end of the main body portion 220 and wind up the main body portion 220 toward the connecting portion 210. Thereby, while the volume of the main body portion 220 decreases, the stored air can spread to the air storage portion 110 through the connecting portion 210. The air that has spread to the air storage portion 110 can be sequentially or simultaneously transferred to a plurality of air storage portions 110 formed in the clothing 100 through the second region 112.

[0085] However, the usage method of such functional clothing 1000 is merely exemplary, and it can be variously modified and applied according to the embodiments to which the present invention is applied by an ordinary technician.
