Here, the air permeability of the lining is appropriately selected according to the usage mode. For example, when the exhaust port is formed in the lining, it is preferable that the air permeability of the lining is low. On the contrary, when the exhaust port is not formed in the lining, it is preferable to increase the air permeability and exhaust the air through the lining fabric to apply the air to the body.

Such exhaust ports may be formed in the lining and / or the outer material. At that time, a flap (a cloth covering the opening), a filter, a mesh cloth, a chuck (zipper), or the like may be attached to the exhaust port.

Hereinafter, the present invention will be described in detail with reference to examples, but the present invention is not limited thereto. In addition, each physical property in an Example was measured by the following method.
(1) Crisp rate The test yarn was wound around a measuring machine having a circumference of 1.125 m to prepare a skein having a dry fineness of 3333 dtex. The skein is suspended from a hanging nail of a scale plate, an initial load of 6 g is applied to the lower portion thereof, and the length L0 of the skein when a load of 600 g is further applied is measured. Immediately after that, the load is removed from the skein, the skein is removed from the hanging nail of the scale plate, and the skein is immersed in boiling water for 30 minutes to develop crimping. The skein after the boiling water treatment is taken out from the boiling water, the water contained in the skein is absorbed and removed by a filter paper, and the skein is air-dried at room temperature for 24 hours. This air-dried skein is suspended from a hanging nail on a scale plate, a load of 600 g is applied to the lower part thereof, the length L1a of the skein is measured after 1 minute, then the load is removed from the skein, and the skein is removed after 1 minute. The length L2a is measured. The crimp ratio (CP) of the test filament yarn is calculated by the following formula.
CP (%) = ((L1a-L2a) / L0) × 100
(2) Stretchability The elongation rate was measured by the JIS L1096-2010 8.16.1 B method.
(3) Method of measuring basis weight The basis weight (g / m ² ) was measured by JIS L1018-1990 6.4.
(4) Cover factor CF
It was calculated by the following formula.
CF = (DWp / 1.1) ^1/2 x MWp + (DWf / 1.1) ^1/2 x MWf
[DWp is the total warp fineness (dtex), MWp is the warp weave density (book / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (book / 2.54 cm). ]

The elongation rate was 4.3% in the warp direction and 11.5% in the weft direction. The air permeability was 10 cc / cm ² / s.

On the other hand, a false twist crimped yarn (167 dtex / 144 fil, crimp ratio 14%) made of polyethylene terephthalate was used to knit a circular knitted fabric having a vertical structure using a 28G single circular knitting machine. Then, the knitted fabric was subjected to a normal dyeing finish process, and was subjected to a water absorption process in the final setting process to form a lining. In such a knitted fabric, the basis weight was 130 g / m ² , the density was 42 courses / 2.54 cm, 41 wales / 2.54 cm, and the elongation rate in the horizontal direction was 50%. It was 120 cc / cm ² / s.

Next, the air-conditioned clothes (the lining was sewn on the back) as shown in FIG. 1 were sewn using the outer material and the lining. At that time, a fan was attached below the back.

When the air-conditioned clothes were worn, the body could be effectively cooled by forcibly generating an air flow in the space between the outer material and the lining of the air-conditioned clothes.

[Example 2]
In Example 1, the same as in Example 1 except that one exhaust port was formed above the back of the outer material as shown in FIG. When the air-conditioned clothes were worn, the body could be effectively cooled by forcibly generating an air flow in the space between the outer material and the lining of the air-conditioned clothes.

[Example 3]
In the first embodiment, the same as in the first embodiment except that one exhaust port is formed above the lining. When the air-conditioned clothes were worn, the body could be effectively cooled by forcibly generating an air flow in the space between the outer material and the lining of the air-conditioned clothes.
