Method for producing a cold-rolled fabric of the present invention, the filament yarn manufacturing step (S1) of twisting the ultraviolet ray shielding fiber 12 to the polyester fiber 11 to produce a filament yarn (10 '); A cold persimmon composition manufacturing step (S2) of preparing a cold persimmon composition to dye the filament yarn 10 '; Cold filament yarn manufacturing step (S3) of dyeing the filament yarn 10 'into the cold sensitized composition and then drying to manufacture the cold filament yarn 10; A moisture-sensitive filament yarn manufacturing step (S4) of twisting the moisture-sensitive fiber 22 on the cotton fibers 21 to produce the moisture-sensitive filament yarn 20; It is characterized in that it comprises a; cold-weaving fabric weaving step (S5) of weaving the cold-cooled fabric 30 by using the cold filament yarn 10 and the moisture-sensitive filament yarn 20 inclined and weft.

The cold-drying fabric 30 has a high-energy ultraviolet ray blocking function, which prevents the temperature from rising due to the ultraviolet rays and prevents damage to the skin. In case of sweating, it does not get tough and wrinkles well, and the contact area with the skin becomes small to provide a refreshing feeling and comfort, and it has semi-permanent antibacterial and deodorizing properties. Therefore, the cold-weaving fabric 30 can be manufactured with cold-wearing clothing such as golf wear or running wear for a long time outdoors in the hot and humid summer, and can keep the cool and comfortable state when wearing cold-cooling clothes.

Hereinafter, the method of manufacturing the cold-cooled fabric and the cold-cooled clothing produced thereby will be described in detail step by step.

First, as shown in FIG. 1, the filament yarn manufacturing step (S1) of twisting the ultraviolet ray shielding fiber 12 on the polyester fiber 11 to produce the filament yarn 10 ′ is performed.

The filament yarn manufacturing step (S1), as shown in Figure 1, while moving one strand of polyester fiber 11 at 10cm / s three of the ultraviolet ray shielding fibers 12 around the polyester fiber 11 ) Is a step of producing a filament yarn 10 'of 40 to 50 s (male) by twisting each other overlapping each other in a spiral shape at a speed of 120 ~ 360rpm. At this time, the injection speed of the ultraviolet ray shielding fiber 12 is preferably 160rpm.

Here, s (number) means the length of the thread according to the weight of 1g, 40-50s means the weight of 40-50m 1g, the higher the number becomes thinner. Usually underwear is 60 ~ 100s, depending on the characteristics and design of the clothes should be used the right number.

Polyester fiber 11 is light, tough and strong against friction, and wrinkles are not so good that the permanent wrinkles are possible. In addition, polyester fiber does not absorb moisture, so it dries well and does not invade mold or insects.

The sunscreen fiber 12 blocks more than 90% of ultraviolet rays having a wavelength of 300 to 400 nm. In manufacturing, micron-sized inorganic materials such as titanium dioxide and zinc oxide are directly incorporated into the fiber by a composite spinning technique, or benzotriazole type or benzo An ultraviolet absorber, such as a phenone organic compound, is made to adsorb | suck to a fiber. The ultraviolet ray shielding fiber 12 prevents an increase in body temperature due to ultraviolet rays by blocking ultraviolet rays of high energy applied from the outside, and also prevents damage to the skin by ultraviolet rays.

Here, if the ultraviolet ray shielding fiber 12 is twisted at a speed of 120 rpm or less, the ultraviolet ray blocking fiber 12 is not sufficiently twisted in the polyester fiber 11, and thus it is difficult to expect the ultraviolet ray blocking property, and the ultraviolet ray blocking fiber 12 is If twisted at a speed of 360rpm or more, the ultraviolet ray shielding fiber 12 is excessively twisted on the polyester fiber 11, making it difficult to produce filament yarn of 40 to 50s (male) and economical efficiency.

Thus, the filament yarn 10 'is manufactured by twisting three strands of the sunscreen fiber 12 on the polyester fiber 11, which is tough and not wrinkled, so it is tough with the sunscreen function to block ultraviolet rays. It has the characteristics of the polyester fiber 11 without wrinkles.

Next, performing a cold-sensitized composition manufacturing step (S2) to produce a cold-sensitized composition to be salted filament yarn (10 ').

The cold persimmon composition is realized by mixing an organic acid, a peppermint oil, an organic binder, and a residual amount of purified water. In this case, the cold persimmon composition includes 30 to 50 parts by weight of an organic acid, more preferably 40 to 45 parts by weight, 5 to 20 parts by weight of peppermint oil, more preferably 10 to 15 parts by weight, and 30 to 100 parts by weight of an organic binder. Is implemented.

The organic acid is endothermic with the moisture of the sweat and can lower the body temperature on the surface of the skin to impart a feeling of cooling. In particular, citric acid has good fixing property and cold feeling property with the adherend among organic acids. These organic acids are citric acid, lactic acid, succinic acid, fumaric acid, ascorbic acid, ascorbic acid, oxalic acid, malonic acid, and glue. One or more mixtures selected from glutaric acid, and propionic acid. If the content of such an organic acid is less than 30 parts by weight, the cooling effect is less, and if the content is contained in excess of 50 parts by weight, there is a problem that the solubility is lowered.

Peppermint oil feels cool and refreshing when it comes into contact with the skin. The content of such pepper oil is in the range of 5 to 20 parts by weight, preferably 10 to 15 parts by weight. At this time, when the content of peppermint oil is less than 5 parts by weight it may be difficult to achieve the expected effect, and when the content of peppermint oil is more than 20 parts by weight is excessive, it inhibits the liquid stability and economically undesired tendency It is better to keep the above range because it is shown.

The organic binder is an ingredient that allows organic acids and peppermint oils to adhere to fibers or fabrics and imparts durability. Specifically, organic binders include one or two or more mixtures selected from silicone resins, urethane resins, acrylic resins, vinyl acetate resins, and melamine resins. Can be used. The content of such an organic binder is preferably used in the range of 30 to 100 parts by weight. If the content of the organic binder is less than 30 parts by weight, the adhesion of components such as organic acids tends to be poor, and if the content of the organic binder is greater than the range of 100 parts by weight, it is not preferable because it tends to inhibit the cooling effect.

Specifically, when the silicone resin is used as the organic binder, the fabric serves to soften the fabric, and to provide adhesion of the organic acid and peppermint oil so as to be well adhered to the fabric of the fabric and to provide durability. It is preferable to use a hydrophilic self-emulsifying silicone resin as the silicone resin, and the content of the silicone resin in the composition is in the range of 40 to 80 parts by weight, preferably 50 to 60 parts by weight.

In addition, when a urethane resin is used as the organic binder, organic acids and peppermint oils are permanently fixed to the fabric and serve to improve the resilience of the fabric (elasticity). The content of the urethane resin in the composition is in the range of 60 to 90 parts by weight, and preferably in the range of 70 to 80 parts by weight. If the content of the urethane resin is less than 60 parts by weight, the durability tends to decrease. If the content of the urethane resin is more than 90 parts by weight, the liquid stability cannot be secured and the softness of the fiber is lowered, which is not preferable.

The organic acid, peppermint oil and the organic binder are mixed with the remaining amount of purified water to form a one-liquid liquid phase, and these cold persimmon compositions have been shown to maintain stability even when stored at room temperature for at least one year.

The above-mentioned cold feeling functional composition of the present invention is a milky white to off-white viscous liquid, which is nonionic and has a weak acidity to neutrality.

Next, a cold filament yarn manufacturing step (S3) of manufacturing the cold filament yarn 10 is performed by dyeing the filament yarn 10 'into the cold sensitized composition and then drying it.

If the cold persimmon composition is diluted with water at a concentration of 15 to 20 parts by weight, it is safe to use. The cold sensitizing composition is applied to the filament yarn 10 'by dipping, and effective when treated for 5 to 15 minutes at pH 5.0 to 6.0 conditions, 60 to 70 ℃ temperature conditions.

If the pH is less than 5.0 or more than 6.0 at the time of dyeing, care should be taken because the absorption of the cold sensitization of the filament yarn 10 'is not sufficient. In addition, when the immersion temperature is less than 60 ° C., the absorption of the cold sensitized composition is not sufficient. If the immersion temperature exceeds 70 ° C., the stability of the cold sensitized composition tends to be impaired. In addition, if the immersion time is less than 5 minutes, the cold persimmon composition tends not to be sufficiently absorbed into the filament yarn 10 ', and if it is longer than 15 minutes, the cold persimmon composition is eluted again and it may be difficult to expect a sufficient cooling effect. .

On the other hand, when the filament yarn 10 ′ in which the cold sensitized composition is absorbed is dried, the organic binder (silicone resin or urethane resin) exhibits a crosslinking effect, and the cold sensitized composition is more firmly fixed to the filament yarn 10 ′. At this time, the drying temperature is preferably in the range of 70 to 90 ℃, the drying time may be performed for 10 to 20 minutes. If the drying temperature is less than 70 ℃, the filament yarn (10 ') is insufficiently secured to the cold sensitization composition, if it is 70 ℃ or more, the components constituting the cold sensitization composition may be modified to not exhibit a sufficient cooling effect. Therefore, it is desirable to dry to the above temperature range. Also note that the drying time may be longer than the above time since the cooling effect may be lowered.

Cold filament yarn 10 produced by the above method, by blocking the high-energy ultraviolet rays irradiated from the outside by the ultraviolet ray shielding fiber 12 can prevent the temperature rise and at the same time prevent skin damage, The cold sensitized composition exhibits an endothermic reaction by reacting with moisture of sweat, thereby lowering the temperature of the skin. The cold sensitized composition is excellent in the adhesion of the cold sensitized composition, and thus maintains cold sensitivity even after 60 washes.

Next, as shown in Figure 2, by twisting the moisture-sensitive fiber 22 to the cotton fiber 21 performs a moisture-sensitive filament yarn manufacturing step (S4) to produce a moisture-sensitive filament yarn (20).

Moisture-sensitive filament yarn manufacturing step (S4), while moving one strand of cotton fiber 21 at 10cm / s, three moisture-sensitive fibers 22 around the cotton fiber 21 at a speed of 120 ~ 360rpm Steps to produce a moisture-sensitive filament yarn 20 of 40 ~ 50s (male) by twisting each other in a spiral shape. At this time, the injection speed of the moisture-sensitive fiber 22 is preferably 160rpm.

Cotton fiber 21 has a high hygroscopicity, when wet with water, the strength is greater, and well resistant to basic soap.

As shown in FIG. 4, when the moisture-sensitive fiber 22 absorbs moisture or sweat, only about 10% of the total fiber area remains on the skin and the remaining 90% is separated from the skin, resulting in stickiness or entanglement during sports activities. It provides a significant improvement. In addition, the inflow of fresh air from the outside can be increased through the space away from the skin, and the drying speed of the fiber can be advanced more than 50% as well as skin respiration. In addition, as the sweat cools down, the reversible response is permanently maintained, restoring its original shape back to its original shape. These moisture-sensitive oils are used by Bentex Co., Ltd. of the Republic of Korea.

As such, the moisture-sensitive filament yarn 20 is manufactured by twisting the moisture-sensitive fiber 22 on the cotton fiber 21 which maintains the moisture absorbed state. Moisture reduces the contact area with the skin, providing a refreshing and comfortable feel.

Next, as shown in FIG. 3, the cold-weaving fabric weaving step (S5) of weaving the cold-cooled fabric 30 with the cold-filament yarn 10 and the moisture-sensitive filament yarn 20 as warp and weft yarns. To perform.

The cold fabric 30 has a cold filament yarn 10 in which the ultraviolet ray shielding fiber 12 is twisted on the polyester fiber 11 and is impregnated with the cold sensitizing composition, and water which absorbs moisture to reduce the contact area with the skin. The filament 20 is woven. Therefore, the cold persimmon clothing of the present invention manufactured by the cold persimmon fabric 30 prevents the temperature rise by blocking the high energy ultraviolet rays at the time of wearing, and prevents the skin from being damaged. It can reduce the temperature of the skin by reacting with moisture of water, and when sweating a lot, the contact area with the skin is reduced by moisture, so it can provide a refreshing feeling and comfort, and it has excellent adhesion of cold composition. Cooling is maintained even with 60 washes. Furthermore, cold clothing has semi-permanent antibacterial and deodorant properties, and can be worn in a comfortable state because it releases the sweat generated in the body to the outside without absorbing it.
