1 to 5 , the cooling garment 100 with improved comfort by utilizing heat of vaporization using the moisture circulation device according to the present invention has a lining 110 , an outer fabric 120 , and the lining 110 . It is disposed between the outer fabric 120 and the intermediate layer 130 for accommodating moisture, and a moisture circulation device 150 for absorbing moisture disposed under the intermediate layer 130 and discharging it from the upper portion of the intermediate layer. can be exemplified.

Referring to FIG. 2 , in this embodiment, only the rear surface surrounding the user's back is accommodated in moisture and the moisture circulation device is installed, but the present invention is not limited thereto and can be changed to accommodate moisture in the front as well as the rear. . However, hereinafter, the embodiment of FIG. 2 will be mainly described.

In this embodiment, the lining 110 is composed of a lining sheet 111 and a first laminating film 112 attached to one surface of the lining sheet 111 .

The lining sheet 111 and the first laminating film 112 may be laminated through an adhesive.

Here, the first laminating film serves to prevent the moisture contained in the intermediate layer from penetrating the user by providing a waterproof performance to the lining.

The first laminating film may be exemplified to have a thickness of 40 to 120 μm.

The outer fabric 120 is composed of an outer fabric sheet 121 and a second laminating film 122 attached to one surface of the outer fabric sheet 121 , and the moisture contained in the intermediate layer 130 is discharged to the outside through the outer fabric. It is characterized in that the structure is

The outer sheet 121 and the second laminating film 122 may be laminated through an adhesive.

The second laminating film 122 provides waterproof and moisture-permeable performance to the outer fabric 120 so that the water contained in the intermediate layer 130 is vaporized and generated water vapor is discharged to the outside, and cooling performance by the heat of vaporization generated at this time plays a role in enabling

The second laminating film may be exemplified to have a thickness of 40 to 120 μm.

And in order to provide smooth moisture permeability performance, for example, it is preferable to have a moisture permeability of 20,000 [g/m 2 ·24h] or more. In order to make the moisture permeability of the entire outer fabric fall within the above-described range, the moisture permeability of the second laminating film must have a level higher than 20,000 [g/m 2 ·24h]. And since the second laminating film having waterproof and moisture permeable performance is already known in Korean Patent Registration No. 10-2092097 and Korean Patent Publication No. 10-2017-0105724, a detailed description thereof will be omitted.

However, in the present invention, the second laminating film having the composition shown in Table 1 below and a liquid adhesive were used to laminate the outer sheet.

ingredient Mixing ratio (parts by weight) 2nd laminating film Polyurethane resin 100 MEK, Methyl-ethyl-ketone 5-15 DMF, Dimethylformamide 5-15 Toluene 15-45 Toner (Black) 5-25 Silica 0.5~3.5 viscosity 3,000~4,500cps/25℃ glue Polyurethane resin 100 MEK, Methyl-ethyl-ketone 5-15 DMF, Dimethylformamide 5-15 Toluene 15-45 crosslinking agent 8-15 catalyst 0.5~2 viscosity 3,000~4,500cps/25℃

In Table 1 above, the second laminating film had a thickness of 40㎛ and was subjected to a multi-stage heat drying process at 70-120°C, and the drying conditions were multi-stage heat drying conditions at 100-130°C when laminating with an outer sheet (knitted fabric) through a liquid adhesive. It was made through drying, and the moisture permeability of the final outer fabric was tested by the FITI Testing Research Institute, and the moisture permeability was measured according to JIS L 1099: 2012, B-1, potassium acetate method. The moisture permeability measurement result is 21,541 [g/m 2 ·24h].

On the other hand, the edge regions of the first laminating film and the second laminating film are bonded to each other in contact with each other. Here, the bonding method may be exemplified by a thermal and high-frequency bonding method, but is not limited thereto.

The intermediate layer 130 of this embodiment has an internal space sealed by a partition line 134 in which the first laminating film 112 and the second laminating film 122 facing each other are bonded in the edge region to accommodate moisture. 131, and an inlet (not shown) for supplying water is formed on one side of the inner space.

In addition, the intermediate layer 130 serves to distribute the moisture absorbing member 133 in the inner space so that moisture or water injected into the intermediate layer can be evenly distributed throughout the clothes.

The moisture absorbing member 133 may be exemplified by processing cellulose fibers into a nonwoven fabric having a basis weight of 100 to 300 g/m 2 , but is not limited thereto.

The cellulose-based fiber may be exemplified by cotton, kapok, flax, hemp, hemp, jute, palm fiber, rayon, acetate, and the like.

The moisture absorbing member is preferably treated with an antibacterial agent because there is a risk of mold or bacteria propagation due to the characteristic of containing moisture for a long time.

The antibacterial agent may be an antibacterial powder coated with silver nanoparticles on the surface of at least one of zeolite and activated carbon powder, or a microcapsule containing an antimicrobial component injected into the intermediate layer.

It goes without saying that the moisture absorbing member may be omitted depending on product characteristics because it has a structure in which moisture flows down from the upper part to the lower part of the intermediate layer through the moisture circulation device.
