Description

  The present invention relates to an air-conditioning garment that cools the body by generating an air flow substantially parallel to the surface of the body, and a method for forming a fan mounting hole in the air-conditioning garment.

  Recently, air-conditioning clothing that cools the body has been sold and widely known (see, for example, Patent Document 1). Such air-conditioning garments include a flow path for circulating air between the clothing and the body or underwear, and a fan attached to the clothing. Here, the fan is usually attached to the lower part on the back side of the clothing. When the air-conditioning garment is worn and the fan is driven, the fan forcibly creates a flow of air in the space between the clothing and the body or underwear, and the air flows on the surface of the body in the space between the clothing and the body or underwear. Will be distributed along. Thereby, the humidity gradient on the surface of the body can be increased, and all the sweat supplied corresponding to the heat radiation amount required by the body can be vaporized. When sweat evaporates, the body is cooled because heat is taken away from the body during the evaporation.

  By the way, in said air-conditioning garment, the fan is directly attached to the cloth. When a fan is attached to clothing, it is necessary to form a circular hole in the clothing. At this time, if only a hole is formed in the cloth, the fiber of the cloth around the hole is frayed. For this reason, it is necessary to prevent fraying on the cloth portion around the hole. FIG. 10A is a diagram for explaining the holes formed in the clothes in the conventional air-conditioning garment and the surrounding clothes, and FIG. 10B is a schematic enlarged view of the cloth parts around the holes. When performing a fray-proof sewing operation, first, a hole is formed at a predetermined position of the clothing. Next, as shown in FIG. 10, after making a large number of cuts in the cloth portion around the hole, the cloth portion is folded back. Then, the portion of the cloth that overlaps with the folded back is sewn with a thread. In this way, as shown in FIG. 10A, the portion is frayed. The fan is attached to the clothing using a portion of the clothing around the hole. As described above, in the air-conditioning garment, there is a problem that the manufacturing cost increases because it is necessary to perform the fraying prevention sewing work at a special place.

  In addition, since the clothing usually stretches to some extent when pulled, there is a problem that if the clothing near the hole is pulled, the shape of the hole becomes large, and the fan is easily detached from the clothing. If the fan is removed from the clothes, naturally the cooling effect cannot be obtained. As a measure for preventing the fan from coming off, for example, it is conceivable to attach a non-stretchable material to the cloth portion around the hole. However, using such a non-stretchable material further increases the manufacturing cost of the air-conditioning garment.

  The present invention has been made based on the above circumstances, and the fan is not easily detached even if the clothes are pulled, and the manufacturing cost can be reduced, and the fan mounting in the air-conditioning garment It is an object of the present invention to provide a method for forming a hole for use.

  The best mode for carrying out the present invention will be described below with reference to the drawings. 1A is a schematic front view of an air-conditioning garment according to the first embodiment of the present invention, FIG. 1B is a schematic rear view of the air-conditioning garment, and FIG. 2 is a diagram for explaining a hole in the air-conditioning garment. FIG. 3 (a) is a schematic plan view of the hole portion and the surrounding clothing portion in the air-conditioning garment, FIG. 3 (b) is a schematic enlarged view of the clothing portion portion around the hole portion, and FIG. 3 (c). ) Is a schematic cross-sectional view in the direction of the arrows AA of the clothing material portion shown in FIG.

  As shown in FIGS. 1, 2 and 3, the air-conditioning garment of the first embodiment includes a clothing material part 10, an opening / closing means 20, an air leakage prevention means 30, an air outflow part 40a, 40b, 40b, Two holes 50, 50, two fans 60, 60, and a battery 70 are provided.

  The clothing material portion 10 covers a predetermined part of the body. Here, a long-sleeved garment is manufactured using the garment portion 10. In addition, the clothing material portion 10 also plays a role of guiding the air generated by the fans 60 and 60 along the surface of the body or the underwear in the space between the clothing material portion 10 and the body or the underwear. In the present embodiment, “underwear” means clothing worn under air-conditioning clothing.

  In order to use the clothing material portion 10 as an air guiding means, the material of the clothing material portion 10 can smoothly flow air in the space between the clothing material portion 10 and the body or underwear, and the air leaks to the outside too much. It is desirable to use something that does not exist. In the first embodiment, a cloth made of plastic fibers (plastic material) such as polyester, acrylic, nylon, or a cloth made by blending plastic fibers is used as the material of the clothing material portion 10. In particular, when the latter fabric is used, it is preferable to use one having a high blend ratio of plastic fibers.

  As shown in FIG. 1A, an opening / closing means 20 is provided at the front of the clothing material portion 10. The opening / closing means 20 is for opening and closing the front portion of the air-conditioning garment. For example, a fastener is used as the opening / closing means 20.

  An air leakage preventing means 30 is provided at the skirt of the clothing material portion 10. The air leakage prevention means 30 is for preventing the air from leaking outside from the hem by bringing the skirt of the fabric portion 10 into close contact with the body, clothes such as underwear or trousers. For example, a stretchable material such as rubber is used as the air leakage prevention means 30.

  The air outflow portions 40a, 40b, and 40b are for taking out the air flowing in the space between the clothing material portion 10 and the body or underwear to the outside. Specifically, the opening formed in the portion around the collar of the clothing material portion 10 is the air outflow portion 40a, and the opening portions formed in the left and right cuff portions of the clothing material portion 10 are the air outflow portions 40b and 40b.

  As shown in FIG. 2, holes 50 and 50 are respectively formed on the left and right sides near the flank of the lower part on the back side of the clothing part 10. The hole 50 is a mounting position of the fan 60. For this reason, the same number of holes 50 as the number of fans 60 are formed. Moreover, the part of the clothing material part 10 in the circumference | surroundings of each hole part 50 and 50 becomes the fan attachment parts 12 and 12 utilized when attaching the fans 60 and 60 to an air-conditioning garment. That is, in FIG. 2, an annular region surrounded by a boundary line between the clothing material portion 10 and the hole portion 50 and a broken line drawn in the shape of a circle is the fan attachment portion 12.

  In the first embodiment, as shown in FIGS. 2 and 3, a solidified portion 12 a is provided at the edge of the fan mounting portion 12 around each hole 50, 50. The solidified portion 12a is formed by heating and softening the plastic fiber that is the material of the clothing material portion 10 and then solidifying it. Here, the solidified portion 12a is formed in a substantially annular shape. As shown in FIG. 3A, the width W of the solidified portion 12a is very narrow, for example, not less than 0.5 mm and not more than 2 mm.

  Specifically, the solidified portion 12a is formed as follows. First, a cutter device having an annular cutter blade having a diameter slightly smaller than the diameter φ of the hole 50 to be formed in the clothing material portion 10 is prepared. Moreover, the clothing material part 10 is fixed to a predetermined position in a pulled state. Next, the cutter blade is heated to a predetermined temperature. Specifically, the temperature of the cutter blade is set to a temperature at which plastic fibers used as the material of the clothing material portion 10 can be softened or higher. Thereafter, the cutter blade is slowly lowered from above to the portion of the clothing material portion 10 where the hole 50 is to be formed. When the cutter blade cuts the clothing material portion 10, the plastic fiber in the cut portion is softened and contracted by the heat from the cutter blade, and penetrates into the surrounding fibers. At this time, since the cutter blade having a diameter slightly smaller than the diameter φ of the hole 50 is used, as a result, the hole 50 formed by cutting has a desired diameter as shown in FIG. It will have approximately the same diameter as φ. Thereafter, the softened plastic fiber gradually cools and solidifies. This solidified portion is a solidified portion 12a. Further, since the solidified portion 12a includes the above-mentioned softened and contracted plastic fibers, the thickness of the solidified portion 12a is larger than the thickness of the other clothing material portions 10. By cutting the clothing material portion 10 using the heated cutter blade in this way, the hole portion 50 and the solidified portion 12a can be simultaneously and easily formed in the clothing material portion 10. Moreover, the solidified portion 12a is very hard and does not expand or contract. Therefore, even if the clothing material part 10 is pulled, the diameter of the hole part 50 does not expand.

  The fans 60 and 60 are for forcibly generating an air flow in the space between the clothing material portion 10 and the body or underwear. The two fans 60 and 60 rotate in a direction in which external air is taken into the clothing material portion 10. When external air is taken into the clothing material part 10 via the fans 60, 60, an air circulation space is automatically formed between the clothing material part 10 and the body or underwear by the pressure of the taken-in air. Is done. Thereby, in the space between the clothing material part 10 and a body or underwear, the flow of the air which wraps up an upper body arises.

  The battery 70 is for supplying power to the fans 60 and 60. The battery 70 and the two fans 60, 60 are connected by a power cable (not shown). A power switch (not shown) is provided between the battery 70 and the two fans 60 and 60. This power switch turns on / off the power supplied from the battery 70 to the two fans 60 and 60. In FIG. 1A, the battery 70 is detachably attached to the jacket, but the battery 70 may be detachably attached to the trousers or detachably attached to the belt. You may make it attach.

  Next, the structure of the fan 60 will be described. FIG. 4A is a schematic front view of a fan 60 used in the air-conditioning garment of the first embodiment, and FIG. 4B is a schematic side view of the fan 60.

  As shown in FIG. 4, the fan 60 includes a motor 61, a propeller-shaped impeller 62, a main body part 63, and an attachment part 64. The motor 61 rotates the impeller 62. The motor 61 and the impeller 62 are accommodated in the main body part 63.

  The main body part 63 is formed in a substantially cylindrical shape. The outer diameter of the body part of the main body part 63 is substantially the same as the inner diameter of the fan mounting part 12 (the diameter of the hole part 50). Further, an annular flange portion 63 a is provided on the upper part of the main body part 63. The flange portion 63 a is formed in substantially the same shape as the fan mounting portion 12.

  The attachment component 64 is formed in a substantially annular shape. The inner diameter of the annular shape is substantially the same as the outer diameter of the body portion of the main body part 63. The attachment part 64 is detachably attached to the main body part 63 so as to cover the body part from the rear side of the main body part 63. For example, the first engagement means is provided in the main body part 63 and the second engagement means is provided in the attachment part 64, and the first engagement means and the second engagement means are engaged with each other. The attachment part 64 can be detachably attached.

  The fan 60 is detachably attached to the clothing material portion 10. FIG. 5 is a schematic cross-sectional view for explaining a state in which the fan 60 is attached to the clothing material portion 10. Here, in FIG. 5, the motor 61 and the impeller 62 are omitted. When attaching the fan 60 to the clothing material portion 10, first, the main body component 63 is inserted into the hole portion 50 from the front side of the clothing material portion 10, and the rear surface of the flange portion 63 a is brought into contact with the fan attachment portion 12. Next, the attachment part 64 is attached to the main body part 63 so as to cover the body part 63 from the back side of the clothing material part 10, and the attachment part 64 is brought into contact with the fan attachment part 12. Thus, as shown in FIG. 5, the fan 60 is attached to the clothing material portion 10 by sandwiching the fan attachment portion 12 between the flange portion 63 a and the attachment component 64. In particular, in the first embodiment, by providing the solidified portion 12a in the fan mounting portion 12, the solidified portion 12a does not expand or contract. Therefore, even if the clothing material portion 10 is pulled, the fan 60 is detached from the clothing material portion 10. There is no end to it.

  In the air-conditioning garment of the first embodiment, a solidified portion formed by softening plastic fibers and then solidifying them is provided at the cloth portion around the hole. And the fan is attached to the clothing material part using the solidification part. Since the solidified portion does not expand or contract, even if the clothing material portion is pulled, the fan does not come off the clothing material portion. In addition, using a cloth made of plastic fiber or a blend of plastic fibers as the material of the cloth part, simply cutting a predetermined part of the cloth part with a heated cutter blade, the hole part and solidifying The part can be easily formed. In addition, it is not necessary to perform a sewing operation on the cloth portion around the hole after the hole is formed as in the prior art. For this reason, the manufacturing cost of the air-conditioning garment can be reduced.

  Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 6A is a schematic plan view of the hole portion and the surrounding clothing portion in the air-conditioning garment according to the second embodiment of the present invention, and FIG. 6B is a schematic enlarged view of the clothing portion portion around the hole portion. FIG. 6 and FIG. 6C are schematic cross-sectional views in the direction of arrows BB of the clothing material portion shown in FIG. In the second embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, the front view and rear view of the air-conditioning garment of the second embodiment are the same as those in FIG. For this reason, when demonstrating the air-conditioning garment of 2nd embodiment below, FIG. 1 will also be referred.

  As shown in FIGS. 1 and 6, the air-conditioning garment of the second embodiment includes a clothing material portion 10, an opening / closing means 20, an air leakage prevention means 30, air outflow portions 40 a, 40 b, and 40 b, and two hole portions. 50, 50, two fans 60, 60, and a battery 70. The air-conditioning garment of the second embodiment is different from that of the first embodiment only in the shape of the solidified portion 12b formed in the portion of the fabric portion 10 around the hole portion 50 as shown in FIG. About another point, it is the same as that of said 1st embodiment.

  Next, the solidification part 12b which is the feature point of the air-conditioning garment of the second embodiment will be described in detail. As shown in FIG. 6, the solidified portion 12 b is provided at the edge portion of the fan mounting portion 12 around each hole 50, 50. Similarly to the first embodiment, the solidified portion 12b is formed by heating and softening the plastic fiber that is the material of the clothing material portion 10 and then solidifying it. In particular, in the second embodiment, the solidified portion 12b is formed in a substantially annular shape having a width of 2 mm to 25 mm. That is, the width of the solidified portion 12b in the second embodiment is much wider than the width of the solidified portion in the first embodiment. Thus, by widening the width of the solidified portion 12b, the area of the solidified portion 12b can be widened and the strength of the solidified portion 12b can be increased. Therefore, the fan 60 can be stably attached to the clothing material portion 10 using the solidified portion 12b having a large area.

  Moreover, in 2nd embodiment, the solidification part 12b is formed so that a solidification rate may become continuously small in each position as it goes to the outer side on the opposite side from the inner side which is the side corresponding to the hole 50. ing. Here, the “solidification rate” means the cross-sectional area with respect to the cross-sectional area in the vicinity of the position when cut at a predetermined position of the solidified portion 12b along a plane perpendicular to the direction from the inner periphery to the outer periphery of the solidified portion 12b. The ratio of the area of the solidified part. FIG. 7 is a graph showing an example of the relationship between the distance from the center of the hole 50 and the solidification rate of the solidified portion 12b. In FIG. 7, the vertical axis represents the solidification rate, and the horizontal axis represents the distance from the center of the hole 50. D1 represents the distance from the center of the hole 50 to a position on the inner periphery of the solidified portion 12b, and D2 represents the distance from the center of the hole 50 to a position on the outer periphery of the solidified portion 12b.

  In the example of FIG. 7, the solidification rate is maximum on the inner periphery of the solidified portion 12b. That is, the plastic fiber is almost solidified there. The solidification rate continuously decreases from the inner periphery to the outer periphery of the solidified portion 12b. The solidification rate is 0% on the outer periphery of the solidified portion 12b. Therefore, the internal state of the solidified portion 12b having such characteristics of the solidification rate is continuously changed from a hard state where most of the plastic fibers are solidified to a soft state of the fabric as it goes from the inner periphery to the outer periphery. Has moved to. By the way, the solidified portion 12b is formed so that the solidification rate is substantially constant regardless of the distance from the center of the hole 50 and the solidification rate is reduced to 0% discontinuously on the outer periphery of the solidified portion 12b. In this case, due to the discontinuity of the internal state at the boundary between the solidified portion 12b and the clothing material portion 10, the strength at the boundary is weakened, and the solidified portion 12b can be removed from the clothing material portion 10 by applying a little force. It will come off. In this case, the fan 60 cannot be attached to the clothing material portion 10 using the solidified portion 12b. In order to avoid such a problem, in the second embodiment, the solidified portion 12b is formed such that the solidification rate continuously decreases at each position from the inner periphery toward the outer periphery.

  Next, a method for forming the solidified portion 12b will be described. FIG. 8 is a diagram for explaining an example of a method for forming the solidified portion 12b. 8, φ2 is the diameter of the hole 50 to be formed in the clothing material portion 10 (inner diameter of the solidified portion 12b), and φ3 is the outer diameter of the solidified portion 12b to be formed in the clothing material portion 10. Therefore, in this case, it is assumed that the annular solidified portion 12b having a width of (φ3−φ2) / 2 is formed.

  In 2nd embodiment, when forming the solidification part 12b, a cutter apparatus as shown in FIG. 8 is used. This cutter device includes a lower mold 110 for placing the clothing material portion 10 and an upper mold 120 having a cutter blade 121 having a cutting edge formed in an annular shape. In the center of the lower mold 110, a hole 111 having the same diameter as the diameter φ2 of the hole 50 to be formed in the clothing material 10 is formed. Further, the cutting edge of the cutter blade 121 has a diameter φ1 slightly smaller than φ2.

  First, as shown in FIG. 8, the clothing material portion 10 is placed on the lower mold 110 while being pulled. Next, the upper mold 120 and the lower mold 110 are each heated to a predetermined temperature. About the upper mold | type 120, the temperature of the cutter blade 121 is made into the temperature which can soften the plastic fiber currently used as the raw material of the clothing material part 10, or more. Specifically, the cutting edge of the cutter blade 121 is set to the highest temperature, and the temperature of the tapered portion of the cutter blade 121 is gradually lowered as the distance from the cutting edge increases. And about the part of the upper mold | type 120 located in the outer side of the cutter blade 121, while making the temperature into the temperature lower than the temperature which can soften a plastic fiber, it gradually gradually goes away from the cutter blade 121. Try to lower. On the other hand, regarding the portion corresponding to the solidified portion 12b to be formed on the clothing material portion 10 in the lower mold 110, the temperature is lower than the temperature at which the plastic fiber can be softened, and from the hole 111. Make it gradually lower as you move away. When the upper mold 120 and the lower mold 110 are set to predetermined temperatures in this way, the solidified portion 12b is formed when the dressing portion 10 is cut by the cutter blade 121 by controlling the speed at which the cutter blade 121 is moved. The heat applied from the upper mold 120 and the lower mold 110 to the portion R1 of the clothing material portion 10 to be made can be gradually reduced as the distance from the cut site increases.

  Next, the upper mold 120 is gradually lowered. Thereby, the cutting edge of the cutter blade 121 cuts the clothing material portion 10, and a hole having a diameter φ1 is formed in the clothing material portion 10. When the upper die 120 is further lowered, the portion R2 of the clothing portion 10 corresponding to the cutter blade 121 is softened and contracted by heat from the cutting edge of the cutter blade 121 and the taper portion thereof, and the clothing portion 10 positioned around it. Soak into part R1. At this time, the heat applied from the upper mold 120 and the lower mold 110 to the portion R1 of the clothing material portion 10 gradually decreases as the distance from the cut portion increases. Therefore, in the portion R1 of the clothing material portion 10, the inner periphery to the outer periphery. The amount of the softened fibers that are soaked differs toward the. In addition, since the portion R2 of the clothing material portion 10 is softened and contracted, the thickness of the portion R1 of the clothing material portion 10 is thicker than the other clothing material portion 10 portions. Further, since the cutter blade 121 having a diameter φ1 slightly smaller than the diameter φ2 of the hole 50 is used, the hole 50 formed by cutting as a result of the portion R2 of the clothing material portion 10 being softened and contracted is It has substantially the same diameter as the desired diameter φ2. Thereafter, when the upper mold 120 is further lowered, the portion R1 of the clothing material portion 10 is pressed by the upper mold 120 and the lower mold 110. Thereby, the surface of the portion R1 becomes a substantially flat surface.

  Thereafter, when the upper mold 120 is pulled up, the softened plastic fiber is gradually cooled and solidified. The portion R1 of the solid clothing portion 10 is a solidified portion 12b. Here, in the second embodiment, when the solidified portion 12b is formed, heat applied from the upper mold 120 and the lower mold 110 to the portion R1 of the clothing material portion 10 gradually decreases as the distance from the cut site increases. By performing the temperature control, in the solidified portion 12b, the solidification rate continuously decreases at each position from the inner periphery toward the outer periphery. Thus, by cutting the clothing material portion 10 using a cutter device as shown in FIG. 8, the hole portion 50 and the solidified portion 12 b can be simultaneously and easily formed in the clothing material portion 10. Moreover, the solidified portion 12b is very hard and does not expand or contract. Therefore, even if the clothing material part 10 is pulled, the diameter of the hole part 50 does not expand.

  The air-conditioning garment of the second embodiment also has the same operations and effects as those of the first embodiment. In particular, in the second embodiment, since the solidified portion is formed in a substantially annular shape having a width of 2 mm or more and 25 mm or less, the area of the solidified portion can be increased and the strength of the solidified portion can be increased. Can be stably attached to the clothing using the solidified portion of the large area. Moreover, the solidification part is formed so that the solidification rate continuously decreases at each position from the inner side corresponding to the hole to the outer side on the opposite side. Thereby, since it can prevent that the intensity | strength in the boundary of a solidification part and a clothing material part becomes weak, a fan can be firmly attached to a clothing material part.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist.

  In each of the above embodiments, the case where two fans are provided in the air-conditioning garment has been described, but one or three or more fans may be provided.

  Moreover, although each said embodiment demonstrated the case where a solidified part was formed in a cloth part using the cutter apparatus which has a heated cutter blade, it is not restricted to this cutter apparatus, For example, using an ultrasonic cutter A solidified portion may be formed.

  Furthermore, although each said embodiment demonstrated the method of using the cutter apparatus which has a heated cutter blade as a method of forming a hole part and a solidification part in a clothing material part, it is a hole in a clothing material part using this method. A part and a solidified part may be formed. FIG. 9 is a diagram for explaining another method for forming a hole and a solidified portion in a clothing material portion. Hereinafter, the method shown in FIG. 9 will be described in detail.

  When the method shown in FIG. 9 is used, it is not always necessary to use a cloth made of plastic fibers or a cloth made by blending plastic fibers as the material of the cloth portion 10a. For example, cotton or the like can be used as the material for the clothing material portion 10a. First, as shown in FIG. 9A, a sheet-like plastic material 15 is placed on a portion corresponding to the mounting position of the fan in the clothing material portion 10a and its periphery. This plastic material 15 is formed in a circular shape. Here, the inside of the circle drawn by the alternate long and short dash line in FIG. 9A is a portion corresponding to the mounting position of the fan, that is, a range where a hole is to be formed later. Next, as shown in FIG. 9B, a heater (heating means) 150 formed in a donut shape is brought close to the clothing material portion 10 a from above the plastic material 15 and pressed against the plastic material 15. Here, the temperature of the heater 150 is set to a temperature at which the plastic material 15 can be softened or higher. However, the temperature of the heater 150 must be lower than the temperature at which the material of the clothing material portion 10a melts. Thus, the plastic material 15 is softened by the heat from the heater 150 and soaks into the clothing material portion 10a. Thereafter, as shown in FIG. 9C, when the heater 150 is separated from the clothing material portion 10a, the softened plastic material is gradually cooled and solidified. Next, by using the cutter blade to cut the clothing material portion 10a corresponding to the mounting position of the fan and the plastic material portion, the hole portion 50 is formed in the clothing material portion 10a, and around the hole portion 50, A solidified portion 12c in which the plastic material is solidified is formed. In the method of FIG. 9 described above, the case where the plastic material is placed on one side of the clothing material portion 10a has been described. However, the plastic material is disposed on both surfaces of the clothing material portion 10a, and the plastic material is soaked from both surfaces of the clothing material portion 10a. You may make it let. In the above-described method, the heater is pressed from above, but this heater may be pressed from below.

  When the hole and solidified portion forming method shown in FIG. 9 is used, the plastic material is formed into an annular shape, and the plastic material is placed only around the clothing portion corresponding to the mounting position of the fan. It may be arranged. This is because the cloth part corresponding to the mounting position of the fan is finally cut by the cutter blade as shown in FIG. Further, instead of the sheet-like plastic material, a powder-like plastic material, for example, one used as an adhesive may be used.

  Further, in the method shown in FIG. 9 described above, the case where the plastic material is softened using the heater has been described. However, the present invention is not limited to this method, and a method capable of melting the plastic material. Any method may be used. For example, instead of a heater, a plastic material may be soaked into the clothing using an ultrasonic welding machine. In this case as well, it is desirable to form the ultrasonic horn in a donut shape in order to efficiently transmit ultrasonic vibration energy to the object to be processed.

As described above, in the air-conditioning garment of the present invention, a solidified portion formed by softening and then solidifying the plastic material is provided in the cloth portion around the hole. And the fan is attached to the clothing material part using the solidification part. Since the solidified portion does not expand or contract, even if the clothing material portion is pulled, the fan does not come off the clothing material portion. Further, for example, a hole and a solidified portion can be easily formed by using a cloth made of plastic fiber as a material for the clothing portion and only cutting a predetermined portion of the clothing portion using a heated cutter blade. . In addition, it is not necessary to perform a sewing operation on the cloth portion around the hole after the hole is formed as in the prior art. For this reason, the manufacturing cost of the air-conditioning garment can be reduced. Therefore, the air-conditioning garment of the present invention can be applied to air-conditioning garments for various uses such as work and outdoor use.
