1 is a perspective view showing an embodiment of a cold-sensitive scarf according to the present invention, Figure 2 is a plan view showing an embodiment of a cold band of the cold-sensitive scarf according to the present invention, Figure 3 is A-A of FIG. 4 is a cross-sectional view of the cold fabric of the present invention, Figure 5 or 7 is a view showing various embodiments of the cold-sensitive scarf according to the present invention.

The cold-sensitive scarf according to the present invention is composed of a cold band 300, the superabsorbent polymer 303 formed in any position of the scarf 100 as shown in FIG.

The cold sense band 300 is manufactured by packing the superabsorbent polymer into a cold fabric as shown in FIGS. 2 and 3 as the most essential components of the present invention.

The superabsorbent polymer 303 is a polymer exhibiting the absorption of fluid due to the introduction of hydrophilic groups in a three-dimensional network structure or a single chain structure through crosslinking between polymer chains, and absorbs water in a short time and releases it for a long time. It is mainly used in sanitary products such as diaper and sanitary nerfkin, civil engineering and construction field, and recently, it is widely used in horticulture, agriculture and industrial field such as moisture retaining agent, condensation inhibitor, freshness maintainer, dehydrating agent. Under these circumstances, various kinds of superabsorbent polymers have been developed.

The superabsorbent polymer used in the present invention is a non-limiting example of the super absorbent polymer that is harmless to the human body, which has been developed so far. Examples of the synthetic resin include polyacryl amide, polyacrylic acid, and polymethacrylic acid. ((Polymethacrylic acid), polyethylene oxide, polyvinyl alcohol, etc., and natural polymers include gelatin, polysaccharides, sodium carboxylmehtyl cellulose, Chitosan can be used.

The cold feeling fabric 301 contains 1 to 10% o.w.f of xylitol or erythritol, which are cold sensitive components that react with water to promote vaporization.

The xylitol (xylitol) and erythritol (Erythritol) is an alcohol that reacts with moisture to cause an endothermic reaction to take away the heat of the surroundings to dissolve as a component to feel cold sensation and endothermic reaction to give a strong refreshing feeling (cool). Such xylitol and erythritol give a cool feeling of cooling and skin cooling action.

The xylitol or erythritol is 1% o.w.f. If it is included less than it is difficult to express cold sensitivity, if it exceeds 10% o.w.f It is preferable to include 1 to 10% o.w.f (on the weight of fiber) because it can feel a sticky touch on the skin surface.

Xylitol or erythritol used in the present invention is preferably used in the form of a dry powder.

As shown in FIG. 4, the cold reduction fabric 301 may include a surface layer 401 in contact with the skin, a moisture retaining layer 403 containing moisture, and a back layer 405 surrounding the superabsorbent polymer.

The surface layer 401 is formed by adding a conductive yarn to the cold-sensitive fiber. Here, the cold-sensitive fiber is a fiber containing natural or synthetic materials such as ceramide and milk protein, and may be a seaweed fiber as a fiber containing a material expressing skin regeneration and cold feeling properties.

The algae fiber is also called alginate fiber, and alginic acid is a kind of polyuronic acid contained in seaweeds (kelp, seaweed, seaweed, etc.), and has a structure in which main atoms are connected in a long chain. Various fibers can be made using the point that can be easily solidified into a fibrous shape, and the present invention serves as a cooling feeling.

The conductive yarns may be incorporated into cold-sensitive fibers and organized to prevent static electricity affecting skin diseases such as itching or erythema.

In addition, the surface layer 401 serves to quickly absorb and remove moisture (sweat) generated from the skin while providing cooling and antistatic properties to the skin.

Therefore, the cold sensitive material included in the surface layer 401 performs skin cooling and regeneration while in contact with the skin. In addition, the cold-sensitive fiber constituting the surface layer 401 can be used as a hydrophilic fiber such as the seaweed fiber to absorb moisture on the surface of the skin to be transferred to the water-retaining layer 403.

The xylitol or erythritol may be included in the surface layer 401.

Meanwhile, the back layer 405 may be formed of synthetic fibers such as polypropylene and polyamide. It is also applicable to microfiber.

The back layer 405 may be organized at a low density to attenuate a phenomenon in which water transferred from the surface layer 401 to the water retaining layer 403 is transferred to the superabsorbent polymer through the back layer 405, and thus may remain in the water retaining layer 403.

On the other hand, the water retaining layer 403 is made of the same material as the surface layer 401, or mixed with synthetic fibers such as polypropylene and polyamide and cold sensitive fibers, or synthetic fibers and cold sensitive fibers, respectively. Can be configured.

The moisture retention layer 403 is formed between the surface layer 401 and the back layer 405.

In the cold cut fabric 301 of the present invention, the surface layer 401 is formed at a relatively low density compared to the water holding layer 403, and the moisture absorbed into the surface layer 401 by the difference in density between the surface layer 401 and the water holding layer 403 is rapidly reduced to the water holding layer due to the capillary phenomenon. You can make it move. Moisture generated in the skin is first absorbed by the surface layer 401 in contact with the skin and then moved to the moisture holding layer 403.

On the other hand, the amount of moisture transferred to the water retaining layer 403 remains a certain amount, the reverse phenomenon occurred in the surface layer 401 and the water holding layer 403 in that the backing layer 405 is a low-density structure, the moisture holding layer 403 is a relatively high density structure In this embodiment, the moisture is not absorbed by the superabsorbent polymer 303 through the back layer 405, and a certain amount remains in the moisture retaining layer 403, thereby maintaining the cold sensitivity of the moisture retaining layer 403.

The cold reduction fabric 301 of the present invention configured as described above contains a certain amount of water in the water retention layer 403 to promote vaporization reaction by xylitol or erythritol to impart cold sensitivity to the fabric, and the moisture absorbed by the super absorbent polymer 303 in a short time. While preventing the escape, the water (sweat) generated in the skin is quickly absorbed and vaporized, or a certain amount remains in the water retaining layer 403, and the rest is absorbed by the superabsorbent polymer.

The surface layer 401 is preferably included in 15 to 95% by weight as a whole fabric. If it is less than 15% by weight it is difficult to express cold sensitivity, and when it exceeds 95% by weight, the functional expression of the cold sense fabric 301 may be weakened.

Synthetic fiber of the back layer 405 is preferably contained in 5 to 85% by weight as a whole fabric. If less than 5% by weight, or more than 85% by weight, the proportion of the hydrophobic fibers is too large to weaken the functional expression of the cold fabric 301.

The moisture retaining layer 403 is preferably included in 1 to 10% by weight as a whole fabric. If it is less than 1% by weight, it is difficult to retain moisture, and thus the cooling function is lowered. If it is more than 10% by weight, too much moisture is contained in the moisture retention layer 403, which lowers the cooling effect and decreases the fit.

In addition, the surface layer 401 to nano-antibacterial, deodorant, far-infrared material of the cold-sensitive material such as ceramide or metallic material such as silver (Ag) and the cold-sensitive material such as xylitol, erythritol to improve the cold sensitivity and antibacterial Functionality such as deodorization, far-infrared radiation and cold sensitivity can also be imparted.

The silver-containing material improves antibacterial and deodorizing properties and emits far infrared rays that are beneficial to the body. Such a silver-containing material may be preferably prepared by coating impregnated with titanium oxide and nano metal salt.

The ceramide is extracted from rice and contains a large amount of sphingoglycolipids, which is effective for cold aesthetic dermatitis, and is widely used as a cold sensitizer in addition to cosmetics. In the present invention, it is possible to perform a coating treatment to improve the cold sensitivity to the cold sense fabric.

Cold band 300 of the cold-sensitive scarves according to the present invention will be easy to attach and detach from the scarf by detachable removable will be easy to wash the scarf to increase the ease of use.

The cold sense band may be sewn and mounted inside the fabric of the scarf, or as shown in Figures 1 and 5 can be configured detachably by attaching the Velcro 305 to any position of the cold sense band 300 and the scarf.

In addition to the detachable method by the Velcro 305, as shown in Figure 5 to form a connection member 307 in the cooling band 300 and to form a coupling member 201 corresponding to the connection member 307 in any position of the scarf cold band 300 It may be detachably attached to the wearing portion 200.

The connection member 307 may use a variety of members, such as buttons, button holes, snap button female buttons, male buttons of the snap button, and the coupling member 201 is used for button holes, buttons, male buttons of the snap button, female buttons of the snap button, etc. Corresponding members should be used according to the connection member 407.

The cold-sensitized band of the cold-sensitized scarf according to the present invention is configured to be detachably attached to the cold-sensitized band 300 from the scarf by easily detachable from the scarf will be able to increase the ease of use by easy washing of the scarf and cold sense band.

In addition, the cold sense band as shown in Figure 5 or 7 may be formed in a variety of scarves, the cold sense band may be formed in various locations, such as the center or the rim of the scarf to suit a variety of uses or environments.

The cold-sensitive scarf according to the present invention configured as described above absorbs moisture in the cold band formed on the scarf, and when the scarf is worn, the absorbed moisture is vaporized by the xylitol or erythritol of the cold fabric, It absorbs heat and gives cold feeling for a long time.

In addition, by using a cold-sensitive fabric composed of a surface layer, a water-retaining layer, and a backing layer, the amount of moisture absorbed by the superabsorbent polymer is controlled so that the cold band is cold for a long time and the moisture (sweat) generated from the skin can be quickly Absorbed by the superabsorbent polymer to increase the comfort of the scarf has an effect of improving the fit.
