Furthermore, in the cooling clothing of the present invention, the hollow fiber membrane is attached to the front side of the clothing body with a thread sewn from the front side to the back side of the clothing body and from the back side to the front side of the clothing body, and the convex portion on the back side of the clothing body, where the thread is engaged as it goes from the front side to the back side of the clothing body and from the back side to the front side, is pulled toward the front side of the clothing body by this thread, making the height of the convex portion lower than the height of the convex portion at the non-engaged part of the thread.
In addition, the cooling clothing of the present invention is such that the yarn is non-water-absorbent.
Furthermore, the cooling clothing of the present invention has a pocket provided on the lower surface side of the clothing body, and the hollow fiber membrane is disposed on the clothing body above this pocket.
In addition, in the cooling clothing of the present invention, the convex portions and concave portions are formed from a mesh fabric that is arranged on the back side of the clothing body and is separate from the fabric that constitutes the clothing body, and this mesh fabric has convex portions that protrude on the side opposite to the surface direction of the clothing body and concave portions that are recessed on the surface side of the clothing body.
Furthermore, in the cooling clothing of the present invention, the hollow fiber membrane is attached to the front side of the clothing body with a thread sewn from the front side to the back side of the clothing body and from the back side to the front side of the clothing body, and the convex portion on the back side of the clothing body, where the thread is engaged as it goes from the front side to the back side of the clothing body and from the back side to the front side, is pulled toward the front side of the clothing body by this thread, making the height of the convex portion lower than the height of the convex portion at the non-engaged part of the thread.
The cooling clothing of the present invention comprises an outer clothing body, an inner clothing body attached to the inside of the outer clothing body, and a blower attached to the outer clothing body and supplying air outside the outer clothing body to the space between the outer clothing body and the inner clothing body, the inner clothing body having a hollow fiber membrane piped on the surface of the inner clothing body facing the outer clothing body or in the middle layer, a water supply hose connected to a water supply section of the hollow fiber membrane and supplying water from the water supply section into the hollow fiber membrane, and water supply means for supplying water to the water supply hose, and the surface of the inner clothing body opposite the outer clothing body has a convex portion protruding toward the side opposite the outer clothing body and a concave portion recessed toward the outer clothing body, the convex portion being water-repellent.
Furthermore, in the cooling clothing of the present invention, the convex portions and concave portions are integrally formed on the side of the fabric constituting the inner clothing body opposite the outer clothing body, and the convex portions are water-repellent and the concave portions are non-water-repellent.
In addition, in the cooling clothing of the present invention, the hollow fiber membrane is attached to the interior clothing body with a thread sewn from the side of the exterior clothing body to the side opposite the exterior clothing body, and from the side opposite the exterior clothing body to the side of the exterior clothing body, and the height of the convex portion on the side opposite the exterior clothing body of the interior clothing body, where the thread extending from the side of the interior clothing body to the side opposite the exterior clothing body and from the side opposite the exterior clothing body to the side of the exterior clothing body, is engaged, is pulled toward the exterior clothing body by this thread, so that the height of the convex portion is lower than the height of the convex portion at the non-engaged portion of the thread.

(Embodiment 1)
1 to 11 show cooling clothing according to a first embodiment of the present invention.
As shown in Figures 1 and 2, the cooling clothing 1 of this embodiment comprises a vest-type clothing body 3 that can be opened at the front with a zipper 2, a hollow fiber membrane 4 piped on the surface of the clothing body 3, a water supply hose 6 connected to a water supply section 5 of the hollow fiber membrane 4 and supplying water from the water supply section 5 into the hollow fiber membrane 4, and a water supply means 7 that supplies water to the water supply hose 6.

The front and back portions of the clothing body 3 each have a hollow fiber membrane 4 arranged in a meandering pattern from top to bottom.
The hollow fiber membrane 4 is cylindrical with numerous through holes on its outer periphery, and the openings at both ends of the cylinder form the water supply section 5, which is connected to a connector 8, and one end of a water supply hose 6 is connected to the connector 8, and the other end of the water supply hose 6 is connected to a water supply means 7.
In other words, water from the water supply means 7 is supplied to the hollow fiber membrane 4 via the water supply hose 6, the connector 8, and the water supply section 5 of the hollow fiber membrane 4, and is supplied to the surface of the clothing body 3 through the through holes on the outer periphery of the hollow fiber membrane 4, wetting the surface of the clothing body 3.

As shown in FIGS. 1 and 10, the water supply means 7 is composed of a water container 9 for storing water and a pump 10 for sucking out the water from the water container 9.
As is well known, the control circuit of the pump 10 comprises a control unit 11 that controls the pump 10, an operation unit 12 connected to the control unit 11, a display unit 13, and a memory 14, and is powered by a battery 15.

A feature of this embodiment is that the clothing body 3 is made of, for example, Teijin Frontier Co., Ltd.'s (Triple Dry (registered trademark), Carat (registered trademark)).
3, the clothing body 3 has a plurality of convex portions 16 on the back side of the clothing body 3 that protrude in the opposite direction to the front side of the clothing body 3, and a plurality of concave portions 17 that are recessed into the front side of the clothing body 3. The convex portions 16 are water-repellent, while the concave portions 17 are non-water-repellent and absorbent.
That is, the left side of FIG. 3 is the body side of the user wearing the clothing body 3, and the right side is the outer surface.
As shown in FIG. 3, the clothing body 3 of this embodiment has a plurality of convex portions 16 and a plurality of concave portions 17 integrally formed on the back side of the fabric constituting the clothing body 3, with the convex portions 16 being water-repellent and the concave portions 17 being water-absorbent (non-water-repellent).

Then, as shown in FIG. 4, the hollow fiber membrane 4 is sewn with thread 18 onto the surface side of the garment body 3 having such a structure.
Specifically, as shown in Figure 4, the hollow fiber membrane 4 is placed on the front side of the clothing body 3, and is attached to the clothing body 3 with thread 18 sewn from the front side to the back side of the clothing body 3 and from the back side to the front side of the clothing body 3.
In this state, the convex portion 16 on the back side of the clothing body 3 is engaged with the thread 18 which runs from the front side to the back side of the clothing body 3 and from the back side to the front side of the clothing body 3, and this thread 18 is pulled toward the front side of the clothing body 3, making the height of the convex portion 16 lower than the height of the convex portion 16 at the non-engaged portion of the thread 18.
To explain this point in more detail, as described above, multiple convex portions 16 and multiple concave portions 17 are formed on the back side of the clothing body 3, and the thread 18 that sews the hollow fiber membrane 4 to the front side of the clothing body 3 engages with the multiple convex portions 16 and multiple concave portions 17.
The part of the convex portion 16 with which the thread 18 is engaged is pulled by the thread 18 toward the surface of the clothing body 3, thereby becoming concave.
Therefore, the height of the part of the protrusion 16 with which the thread 18 is engaged is lower than the height of the other protrusions 16 with which the thread 18 is not engaged.

In this embodiment, with the above-described configuration, the effects shown in FIGS. 5 and 6 are achieved.
First, as described above, water from the water supply means 7 is supplied to the hollow fiber membrane 4 via the water supply hose 6, the connector 8, and the water supply section 5 of the hollow fiber membrane 4, and is then supplied to the surface of the clothing body 3 through the through holes on the outer periphery of the hollow fiber membrane 4, wetting the surface of the clothing body 3.
In Figure 5, to facilitate understanding, water 19 is shown on the surface side of the clothing body 3, flowing out from the through holes of the hollow fiber membrane 4 into the clothing body 3. In reality, however, this water 19 soaks into the clothing body 3, diffuses over a wide area of the clothing body 3, and then evaporates (vaporizes) from the surface side of the clothing body 3, as shown in Figure 6.
At this time, the heat of vaporization cools the body 20 inside the clothing body 3 via the clothing body 3 and the air inside the clothing body 3. In other words, by lowering the temperature of the clothing body 3, the body wearing the clothing body 3 can be cooled.
In FIG. 5, the arrow pointing toward the body 20 is marked with an X to indicate a state in which the water 19 that has soaked into the clothing body 3 does not flow out toward the body 20.

As described above, the back side (body 20 side) of the clothing body 3 is provided with a protrusion 16 that protrudes in the opposite direction to the front side of the clothing body 3, and this protrusion 16 is water-repellent.
Therefore, although the water 19 that has soaked into the clothing body 3 is dispersed over a wide area of the clothing body 3, it evaporates (vaporizes) from the surface side of the clothing body 3 as shown in Figure 6 and does not flow out to the body 20 side.
Therefore, even though the cooling clothing 1 uses water 19, the body 20 is not wet with the water 19, making it comfortable.

A characteristic feature of this embodiment is that the hollow fiber membrane 4 is placed on the front side of the clothing body 3, as shown in Figure 4, and is attached to the clothing body 3 with thread 18 sewn from the front side to the back side of the clothing body 3 and from the back side to the front side of the clothing body 3.
In this state, in this embodiment, the convex portion 16 on the back side of the clothing body 3 pulls the engagement portion where the thread 18, which runs from the front side to the back side of the clothing body 3 and from the back side to the front side of the clothing body 3, toward the front side of the clothing body 3 with the thread 18, making the height of the convex portion 16 lower than the height of the convex portion 16 at the non-engaging portion of the thread 18.

The reason for this is that when the hollow fiber membrane 4 is sewn to the clothing body 3 with thread 18, there is a risk that some of the water 19 will leak out along the surface of the thread 18 to the back side of the clothing body 3, and this is to prevent this.
In this way, by making the height of the convex portion 16 where the thread 18 is engaged lower than the height of the convex portion 16 where the thread 18 is not engaged, even if some of the water 19 flows down the surface of the thread 18 to the back side of the clothing body 3, that portion is lower than the other convex portions 16 and will not reach the body 20, so the body 20 will not get wet.

Furthermore, even if a small amount of water 19 flows out to the protrusion 16 where the thread 18 is engaged, it is repelled by the water-repellent treated protrusion 16 and then flows into the recess 17 adjacent to that part.
Since the recesses 17 are water-absorbing portions that have not been treated with a water-repellent coating, water is absorbed here, moves to the surface of the clothing body 3, and evaporates.
Sweat 21 shown on the body 20 in FIG. 6 is absorbed by the recesses 17, which are water-absorbing portions that have not been treated with water repellent, moves to the surface of the clothing body 3, and evaporates.
In other words, water 19 from the clothing body 3 rarely reaches the surface of the body 20, and sweat 21 on the surface of the body 20 also moves to the surface side of the clothing body 3 through the recesses 17 and evaporates.
This makes it extremely comfortable.

Furthermore, if the threads 18 are made of a non-water-absorbent material such as nylon, the movement of water 19 from the front side to the back side of the garment body 3 via the threads 18 can be further suppressed.

As shown in FIG. 1, the cooling clothing 1 of this embodiment has a pocket 22 for storing a water supply means 7 and the like at the lower surface side of the clothing body 3, and the hollow fiber membrane 4 is disposed in the clothing body 3 above this pocket 22.
In other words, if part of the hollow fiber membrane 4 is covered by the pocket 22, an area will be formed in which the water 19 that flows out of the hollow fiber membrane 4 and spreads throughout the clothing body 3 will not evaporate smoothly, and this is to avoid this.

7 to 9 and 11 show examples of effective use of the clothing body 3 of this embodiment.
That is, first, the clothing body 3 is put on the body 20, and then the air-cooled clothing 23 shown in FIGS.
As is well known, the air-cooled suit 23 is equipped with two fans 24 for introducing outside air.
As shown in FIG. 11, the blower 24 is connected to a control unit 25 (see fans 1 and 2 in the same figure), and the control unit 25 is connected to a display unit 26, an operation unit 27, a memory 28, and a battery 29.
That is, by operating the operating section 27, the blower 24 is driven by the battery 29, and outside air is introduced into the air-cooled suit 23, and the introduced air is made to flow along the surface of the suit body 3, rise inside the air-cooled suit 23, and flow out from the neck and sleeves to the outside of the air-cooled suit 23.
This air flow effectively vaporizes the water 19 supplied to the clothing body 3, thereby enhancing the cooling effect on the body 20.

In this embodiment, the hollow fiber membrane 4 is arranged on the surface side of the clothing body 3, but if the clothing body 3 is multi-layered, the hollow fiber membrane 4 can also be arranged in the middle layer of the clothing body 3.
For example, if the clothing body 3 is constructed by providing another layer of fabric on the surface side of the clothing body 3, the hollow fiber membrane 4 will be provided in the inner layer of the clothing body 3.

Second Embodiment
FIG. 12 shows a second embodiment of the present invention.
In this embodiment, a mesh fabric 31 separate from the fabric constituting the clothing body 3 is provided on the back side (the side facing the body 20) of the clothing body 3.
That is, as shown in FIG. 12, the mesh fabric 31 is configured to form the convex portions 16 and the concave portions 17, with the convex portions 16 being water-repellent and the openings near the concave portions 17 being water-absorbing (non-water-repellent).
The mesh fabric 31 having such a configuration is also sewn to the clothing body 3 with the thread 18 used to sew the hollow fiber membrane 4.
Specifically, as shown in Figure 4, the hollow fiber membrane 4 is placed on the front side of the clothing body 3, and is attached to the clothing body 3 with thread 18 sewn from the front side to the back side of the clothing body 3 and from the back side to the front side of the clothing body 3.
In this state, the part on the back side of the clothing body 3 where the thread 18 engages with the convex part 16 of the mesh fabric 31 is pulled toward the front side of the clothing body 3 by the thread 18, and the height of the convex part 16 where the thread 18 engages is made lower than the height of the convex part 16 at the non-engaged part of the thread 18.
To explain this point in more detail, multiple convex portions 16 and multiple concave portions 17 are formed on the back side of the mesh fabric 31, and the thread 18 that sews the hollow fiber membrane 4 to the front side of the clothing body 3 engages with the multiple convex portions 16 and multiple concave portions 17.
The part of the convex portion 16 with which the thread 18 is engaged is pulled by the thread 18 toward the surface of the clothing body 3, thereby becoming concave.
Therefore, the height of the part of the protrusion 16 with which the thread 18 is engaged is lower than the height of the other protrusions 16 with which the thread 18 is not engaged.
With this configuration, it is possible to achieve the same effects as in the first embodiment.

Of course, the mesh fabric 31 can also be sewn to the clothing body 3 with other threads. In this case, the height of the protruding portions 16 where the other threads are engaged is made lower than the height of the protruding portions 16 where the other threads are not engaged.

(Third embodiment)
13 to 23 show a cooling garment 32 according to a third embodiment of the present invention.
As shown in FIGS. 13 to 16, the cooling clothing 32 of this embodiment comprises an outer clothing body 33 and an inner clothing body 34 attached to the inside of the outer clothing body 33.
The outer periphery of the inner clothing body 34 is sewn to the corresponding part of the outer clothing body 33, thereby forming a space covered by the inner clothing body 34 within the outer clothing body 33.
However, the inner clothing body 34 and the outer clothing body 33 are not sewn together at the neck, underarms, etc., so that air outlets are formed at the neck and underarms.

Two fans 35 are attached to the lower back of the outer clothing body 33 to supply air from outside the outer clothing body 33 to the space between the outer clothing body 33 and the inner clothing body 34 .
A hollow fiber membrane 36 is piped on the surface of the inner clothing body 34 facing the outer clothing body 33, and a water supply hose 38 is connected to a water supply section 37 of this hollow fiber membrane 36, which supplies water from this water supply section 37 into the hollow fiber membrane 36, and a water supply means 39 is connected to this water supply hose 38.
The front and rear portions of the interior garment body 34 each have a hollow fiber membrane 36 disposed in a serpentine pattern from top to bottom.

The hollow fiber membrane 36 is cylindrical with numerous through holes on its outer periphery, and the openings at both ends of the cylinder form water supply sections 37, which are connected to a connecting body 40.One end of a water supply hose 38 is connected to the connecting body 40, and the other end of the water supply hose 38 is connected to a water supply means 39.
In other words, water from the water supply means 39 is supplied to the hollow fiber membrane 36 via the water supply hose 38, the connector 40, and the water supply section 37 of the hollow fiber membrane 36, and is supplied to the surface side of the interior clothing body 34 (the surface facing the outer clothing body 33) through the through holes on the outer periphery of the hollow fiber membrane 36, wetting the surface of the interior clothing body 34.

As shown in FIGS. 15 and 20, the water supply means 39 is composed of a water container 41 for storing water and a pump 42 for sucking out the water from the water container 41.
As is well known, the control circuit of the pump 42 comprises a control unit 43 that controls the pump 42, an operation unit 44 connected to the control unit 43, a display unit 45, and a memory 46, and is powered by a battery 47.

A feature of this embodiment is that the interior clothing body 34 is made of, for example, Teijin Frontier Co., Ltd.'s (Triple Dry (registered trademark), Carat (registered trademark)).
17, the inner clothing body 34 has a plurality of convex portions 48 formed on the back side of the inner clothing body 34 that protrude in the opposite direction to the surface direction of the inner clothing body 34 (toward the outer clothing body 33), and a plurality of concave portions 49 formed on the surface side of the inner clothing body 34 (toward the outer clothing body 33), and the convex portions 48 are water-repellent. The concave portions 49 are not water-repellent and are water-absorbent.
That is, the left side of FIG. 17 is the body side of the user wearing the cooling clothing 32, and the right side is the outer surface side (the outer clothing main body 33 side).

As shown in Figure 17, in the interior clothing body 34 of this embodiment, the convex portions 48 and concave portions 49 are integrally formed on the back side of the fabric constituting the interior clothing body 34, and the convex portions 48 are water-repellent and the concave portions 49 are water-absorbing (non-water-repellent).
18, a hollow fiber membrane 36 is sewn with thread 50 onto the surface side (the outer clothing body 33 side) of the inner clothing body 34 having such a configuration.
Specifically, as shown in Figure 15, the hollow fiber membrane 36 is arranged on the surface side (exterior clothing body 33 side) of the interior clothing body 34, and is attached to the interior clothing body 34 with thread 50 sewn from the surface side to the back side of the interior clothing body 34 and from the back side to the surface side of the interior clothing body 34.
In this state, the engagement portion of the convex portion 48 on the back side of the interior clothing body 34, where the thread 50 extending from the front side to the back side of the interior clothing body 34 and from the back side to the front side of the interior clothing body 34, is engaged, is pulled by the thread 50 toward the front side of the interior clothing body 34 (toward the exterior clothing body 33), making the height of the convex portion 48 lower than the height of the convex portion 48 at the non-engaging portion of the thread 50.
To explain this point in more detail, as described above, multiple convex portions 48 and multiple concave portions 49 are formed on the back side of the interior clothing body 34, and the thread 50 that sews the hollow fiber membrane 36 to the front side of the interior clothing body 34 engages with the multiple convex portions 48 and multiple concave portions 49.
The portion of the convex portion 48 with which the thread 50 is engaged is pulled by the thread 50 toward the surface side of the interior clothing body 34, and becomes recessed.
Therefore, the height of the portion of the convex portion 48 with which the thread 50 is engaged is lower than the height of the other convex portions 48 with which the thread 50 is not engaged.

In this embodiment, with the above-described configuration, the effects shown in FIGS. 22 and 23 are achieved.
First, as described above, water from the water supply means 39 is supplied to the hollow fiber membrane 36 via the water supply hose 38, the connector 40, and the water supply section 37 of the hollow fiber membrane 36, and then supplied to the surface side (external clothing body 33 side) of the interior clothing body 34 through the through holes on the outer periphery of the hollow fiber membrane 36, wetting the surface side (external clothing body 33 side) of this interior clothing body 34.
To facilitate understanding, Figure 22 shows water 51 flowing out from the through holes of the hollow fiber membrane 36 to the surface side of the interior clothing body 34 (the outer clothing body 33 side), but in reality, this water 51 soaks into the interior clothing body 34, diffuses over a wide area of the interior clothing body 34, and then evaporates (evaporates) from the surface side of the interior clothing body 34 (the outer clothing body 33 side) as shown in Figure 23.
At this time, the body 52 inside the interior clothing body 34 is cooled by the heat of vaporization.
In other words, by lowering the temperature of the interior clothing body 34, the body wearing the interior clothing body 34 can be cooled.
In FIG. 23, the arrow pointing to the body 52 is marked with an X to indicate the state in which the water 51 that has soaked into the inner garment body 34 does not flow out toward the body 52 .

As described above, the inner garment body 34 has a convex portion 48 on the back side (body 52 side) that protrudes in the opposite direction to the front side of the inner garment body 34, and the convex portion 48 is water-repellent.
Therefore, the water 51 that has soaked into the interior clothing body 34 is dispersed over a wide area of the interior clothing body 34, but as shown in Figure 23, it evaporates from the surface side of the interior clothing body 34 and does not flow out to the body 52 side.
Therefore, even though the cooling clothing 32 uses water 51, the body 52 is not wet with the water 51, and the clothing is comfortable.

A characteristic feature of this embodiment is that the hollow fiber membrane 36 is placed on the surface side of the interior clothing body 34, as shown in Figure 18, and is attached to the interior clothing body 34 with thread 50 sewn from the surface side to the back side of the interior clothing body 34 and from the back side to the surface side of the interior clothing body 34.
The convex portion 48 on the back side of the interior clothing body 34 is engaged with the thread 50 which runs from the front side to the back side of the interior clothing body 34 and from the back side to the front side of the interior clothing body 34, and this thread 50 is used to pull the engaging portion toward the front side of the interior clothing body 34, making the height of the convex portion 48 lower than the height of the convex portion 48 at the non-engaging portion of the thread 50.

The reason for this is that when the hollow fiber membrane 36 is sewn to the interior clothing body 34 with thread 50, there is a risk that some of the water 51 will leak out along the surface of the thread 50 to the back side of the interior clothing body 34, and this is to prevent this.
In this way, by making the height of the convex portion 48 where the thread 50 is engaged lower than the height of the convex portion 48 where the thread 50 is not engaged, even if some of the water 51 flows down the surface of the thread 50 to the back side of the interior clothing body 34, that portion is lower than the other convex portions 48 and will not reach the body 52, so the body 52 will not get wet.

Furthermore, even if a small amount of water 51 flows out to the convex portion 48 where the thread 50 is engaged, it is repelled by the water-repellent treated convex portion 48 and then flows into the concave portion 49 adjacent to that portion.
Since the recesses 49 are water-absorbing portions that have not been treated with a water-repellent treatment, water is absorbed here, moves to the surface side of the interior garment body 34, and evaporates.
In FIG. 23, sweat 53 on the body 52 is absorbed by the recesses 49, which are water-absorbing portions that have not been treated with water repellent, and moves to the surface side of the interior garment body 34, where it evaporates.
That is, the water 51 from the inner garment body 34 rarely reaches the surface of the body 52, and the sweat 53 on the surface of the body 52 also moves to the surface side of the inner garment body 34 and evaporates.
This makes it extremely comfortable.

Furthermore, if the thread 50 is made of a non-water-absorbent material such as nylon, the movement of water 51 from the front side to the back side of the interior garment body 34 via the thread 50 can be further suppressed.

The cooling clothing 32 of this embodiment comprises an outer clothing body 33 and an inner clothing body 34 attached to the inside of the outer clothing body 33.
Two fans 35 are attached to the lower back of the outer clothing body 33 to supply air from outside the outer clothing body 33 to the space between the outer clothing body 33 and the inner clothing body 34 .
As shown in FIG. 21, the blower 35 is connected to a control unit 54 , which is connected to a display unit 55 , an operation unit 56 , a memory 57 , and a battery 58 .
In other words, by operating the operating unit 56, the blower 35 is driven by a battery 58, and as shown in Figure 19, air from outside the outer clothing body 33 is introduced into the space between the outer clothing body 33 and the inner clothing body 34, and the introduced air is made to rise along the surface of the inner clothing body 34 and flow out of the cooling clothing 32 from the openings in the neck and sleeves.
This air flow effectively vaporizes the water 51 supplied to the interior clothing body 34, thereby enhancing the cooling effect on the body 52.

In addition, when air outside the outer clothing body 33 is introduced into the space between the outer clothing body 33 and the inner clothing body 34, the air pressure presses the inner clothing body 34 against the body 52, which also enhances the cooling effect.
In other words, when the cool interior clothing body 34 is pressed against the body 52, the cooling effect on the body 52 is enhanced.

In this embodiment, as shown in FIG. 16, a blower 35 is provided below the outer clothing body 33, and the hollow fiber membrane 36 is disposed above the blower 35 in the inner clothing body 34.
This is because the water 51 supplied to the interior clothing body 34 is effectively vaporized by the air blown from the blower 35, thereby enhancing the cooling effect on the body 52.

In this embodiment, the hollow fiber membrane 36 is placed on the surface side of the interior clothing body 34, but if the interior clothing body 34 is multi-layered, the hollow fiber membrane 36 can also be placed in the middle layer of the interior clothing body 34.
For example, if the interior clothing body 34 is constructed by providing another layer of fabric on the surface side of the interior clothing body 34, the hollow fiber membrane 36 will be provided in the inner layer of the interior clothing body 34.

(Fourth embodiment)
FIG. 24 shows a fourth embodiment of the present invention.
In this embodiment, a mesh fabric 59 separate from the fabric constituting the interior clothing body 34 is provided on the back side (body 52 side) of the interior clothing body 34 .
That is, even in the mesh fabric 59, as shown in FIG. 24, the convex portions 48 and the concave portions 49 are configured so that the convex portions 48 can be configured in a water-repellent state and the openings near the concave portions 49 can be configured in a water-absorbing state (non-water-repellent state).
The mesh fabric 59 having such a configuration is also sewn to the interior clothing body 34 with the thread 50 used to sew the hollow fiber membrane 36 .
Specifically, as shown in Figure 18, the hollow fiber membrane 36 is placed on the surface side of the interior clothing body 34, and is attached to the interior clothing body 34 with thread 50 sewn from the surface side to the back side of the interior clothing body 34 and from the back side to the surface side of the interior clothing body 34.
In this state, the part on the back side of the interior clothing body 34 where the thread 50 engages with the convex part 48 of the mesh fabric 59 is pulled toward the front side of the interior clothing body 34 by the thread 50, and the height of the convex part 48 where the thread 50 engages is made lower than the height of the convex part 48 at the non-engaged part of the thread 50.
To explain this point in more detail, multiple convex portions 48 and multiple concave portions 49 are formed on the back side of the mesh fabric 59, and the thread 50 that sews the hollow fiber membrane 36 to the front side of the interior clothing body 34 engages with the multiple convex portions 48 and multiple concave portions 49.
The portion of the convex portion 48 with which the thread 50 is engaged is pulled by the thread 50 toward the surface side of the interior clothing body 34, and becomes recessed.
Therefore, the height of the portion of the convex portion 48 with which the thread 50 is engaged is lower than the height of the other convex portions 48 with which the thread 50 is not engaged.

With this configuration, it is possible to achieve the same effects as in the third embodiment.
Of course, the mesh fabric 59 can also be sewn to the interior clothing body 34 with other threads, in which case the height of the convex portion 48 with which the other threads are engaged is made lower than the height of the convex portion 48 with which the other threads are not engaged.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. Furthermore, various design modifications can be made to the present invention without departing from the scope of the claims.
