The opening and closing flap 13 may be made of a material such as a zipper It can be obviously substituted by known opening and closing means.

In the pocket 11 of the above-described vest body 10, a cooling pack 20 for providing a cold feeling is accommodated in a drawable manner. FIG. 4 shows a detailed structure of such a cooling pack.

The cooling pack 20 is formed based on a cold-weather nonwoven fabric 21 which is needle-punched by mixing superabsorbent cellulose fibers and polyester fibers.

Cellulose is a polymer compound in which D-glucose is bonded in a straight chain form with (1-4) -? - type glycosidic bonds, and is obtained by defatting mainly cotton fibers and boiling them with a dilute aqueous alkali solution. The cellulosic fiber has a high absorptivity due to a large number of hydroxy groups such as -OH on the molecular structure of the cell.

The cellulose fiber material swells when water is absorbed to exhibit air permeability, and when dried, it is restored to its original state and has low air permeability.

4, the cooling pack 20 includes a cold felt nonwoven fabric 21 which is a needle punched mixture of superabsorbent cellulose fibers and polyester fibers, a waterproof fabric 23 laminated on one surface of the cold felt nonwoven fabric 21 And a mesh net fabric 25 which is laminated on the other side of the cold felt nonwoven fabric 21.

The cold feeling nonwoven fabric 21 is preferably prepared by needle punching 100 parts by weight of superabsorbent cellulose fibers and 50 to 200 parts by weight of polyester fibers.

In the case of needle punching with less than 50 parts by weight of polyester fibers on the basis of cellulose fibers, there is a problem that the supporting force against the cellulose fiber material is lowered and the weight feeling is generated due to excessive water absorption. On the basis of the cellulose fibers, When the polyester fiber is added in an amount exceeding the above range, there is a problem that the cold feeling property based on the absorption of water is deteriorated.

The waterproof fabric 23 protects one side surface of the cold felt nonwoven fabric and is positioned on the surface of the wearer's body when the cooling pack 20 is inserted into the pocket 11 so that moisture absorbed by the cold felt non- And serves to prevent the possibility of being transmitted to the body, and is formed of a conventional synthetic resin material waterproof fabric.

The mesh fabric 25 protects the other surface of the cold-weather nonwoven fabric 21 and allows the water to be transferred to the cold-weather nonwoven fabric, and is formed of a general synthetic resin mesh fabric.

The cooling pack 20 described above is preferably integrally laminated by quilting in a state where the cold-weather nonwoven fabric 21 is sandwiched between the waterproof fabric 23 and the mesh cloth 25. However, Or may be integrated by a method.

FIG. 5 is a graph showing the cold sensation characteristics of the cold-weather nonwoven fabric tested through the KITRI.

In order to test the cold feeling property of the cold felt nonwoven fabric 21 described above, 100 parts by weight of superabsorbent cellulose fibers and 100 parts by weight of polyester fibers were mixed with a needle punching cold felt nonwoven fabric 21 to form a square having a width of 120 mm and a length of 120 mm The temperature change of the cold-weather nonwoven fabric (21) was measured at the time of moisture contact with the Korean clothing test institute.

The temperature change of the cold felt nonwoven fabric (21) was measured in a constant temperature and humidity chamber maintained at a temperature of 30 ° C and a humidity of 50%. The sample was immersed in water at room temperature for 21 minutes at room temperature for 10 minutes, After dehydration for 10 seconds, a thermometer was inserted between the two samples and the measurement was carried out for 240 minutes. The results are shown in Table 1 below. FIG. 5 is a schematic diagram of Table 1.

As can be seen from Table 1 and FIG. 5, in the case of the cooling pack 20 based on the cold-weather nonwoven fabric 21 in which the superabsorbent cellulose fibers and the polyester fibers were mixed and needle punched, water was added to the superabsorbent cellulose fibers As a result of being absorbed and maintained for a long time, the cold feeling property is maintained even after 240 minutes.

In order to improve the cooling property of the cooling pack 20, the fine cold powder obtained by making the sugar alcohol into fine powder at the time of mixing the superabsorbent cellulose fiber and the polyester fiber is further added in an amount of 1.0 to 10.0% by weight relative to the superabsorbent cellulose fiber .

Sugar alcohols provide cold sensation through an endothermic reaction and include erythritol, xylitol, sorbitol, maltitol, mannitol, isomalt, stevioside, At least one selected from the group consisting of thaumatin, D-xylose, D-ribose, and L-sorbose can be selected.

Sugar alcohols such as erythritol, xylitol, sorbitol, mannitol, and maltitol, which are cold ingredients, are functional sugars having a molecular structure in which aldehyde groups of common sugars such as glucose, maltose, xylose and the like are reduced to alcohol groups. It is widely used.

Sugar alcohol, which is a cold component, does not have a carnitine denaturation because it does not have a free carbonyl group. It is stable to heat as compared with other monosaccharides and disaccharides, is not easily decomposed by microorganisms, . Such sugar alcohols are mainly used for dental caries prevention and low-calorie functional sugars and are used as substitute sweeteners for sugar in various fields such as foods, medicines and cosmetics. Particularly when sugar alcohol has high heat of dissolution and is dissolved by contact with saliva or perspiration And has a cooling refreshing effect.

The cold storage vest 1 according to the embodiment of the present disclosure as described above is a thin cold cooling pack 20 based on a cold-weather nonwoven fabric 21 in which cellulose fibers having superabsorbent properties are mixed with polyester fibers and needle- ), The wearer can work comfortably without feeling heavy or bulky.

In addition, since the cooling pack 20, which can be used immediately after the cooling pack 20 is dipped in water for a short time and is worn by hand, is applied, the cooling pack can be used conveniently without any inconvenience such as freezing the cooling pack for a long time.
