Figure 7 is an enlarged cross-sectional view of a cold-sensitive fabric according to an embodiment of the present invention.

The cool-sensitive fabric according to an embodiment of the present invention includes a fibrous fabric 10 as shown in FIG. 1.

The textile fabric 10 includes a fabric body 11 having an inner surface 11a and an outer surface 11b in direct contact with the skin, and a water-repellent layer pattern applied to the surface of the inner surface 11a of the fabric main body 11 ( 12), it includes an absorption layer pattern 13 applied to the surface of the outer surface 11b of the fabric body 11.

The fabric body 11 is mainly made of synthetic fibers such as polyethylene and polyester, and may be made of blended fibers with natural fibers if necessary.

The water-repellent layer pattern 12 is made of a liquid water-repellent composition and has a regular polygonal pattern shape formed by connecting regular polygons such as regular triangles, squares, pentagons, regular hexagons, and regular octagons in a plane, and is formed on the inner surface (11a) of the fabric main body 11. ) It is applied to the surface and dried. The water-repellent composition includes a water-repellent agent for textiles and a binder mixed in a weight ratio of 6:4 to 5:5.

The water repellent is preferably a silicone-based or fluorine-based water repellent that is widely used, but is not limited thereto. Such water repellent agents function to prevent water from being absorbed by increasing the contact angle when in contact with water.

The binder functions to attach the water repellent to the fabric body 11, and a water-based acrylic or urethane-based binder may be used, but is not limited thereto. Through this binder, the water-repellent layer pattern 12 can maintain adhesion to the fiber, and thus can exhibit water-repellent performance without deterioration even after repeated washing.

In this example, microcapsules containing germanium nanopowder may be added to the water-repellent composition. Germanium is widely known as a substance that exerts various physiologically active effects such as promoting oxygen supply, strengthening immune function, producing endorphins, and eliminating pain, and is mainly introduced in the form of bracelets, necklaces, waist belts, etc., and in the present invention, these We intend to exert bioactive functions by nano-powdering germanium and including it in the textile fabric (11).

When germanium nanopowder is attached directly to the textile fabric 11 through the binder, the germanium nanopowder is soluble in water even in a small amount and falls off due to physical influence during washing. Therefore, in the present invention, this micro It is encapsulated so that it can be firmly attached to the textile fabric 11 through the binder.

The size of the microcapsule is preferably 10 to 50 μm. If it exceeds 50㎛, there is a greater risk of it falling off due to external force during washing, and if it is less than 10㎛, it becomes difficult to accommodate the germanium nanopowder inside the capsule. The material of the microcapsule can be melamine, melamine-formaldehyde, urea polymer, etc.

It is desirable that microcapsules containing such germanium nanopowder be contained in approximately 5% of the total water-repellent composition.

Additionally, in this embodiment, sustained-release microcapsules containing a natural antibacterial and deodorizing agent may be added to the water-repellent composition. As the natural antibacterial deodorant, plant-derived ingredients such as dermal extract, yellow white extract, yellow lotus extract, ginger yellow extract, and clove extract can be used. Alternatively, deodorizing/deodorizing substances such as tea extract, persimmon extract, mugwort extract, perilla extract, aloe extract, and hinokitiol can be used.

By converting such a natural antibacterial deodorant into sustained-release microcapsules, it can exert a continuous antibacterial and deodorizing function by slowly leaking out of the microcapsules even during repeated washing.

The absorbent layer pattern 13 applied to the surface of the outer surface 11b of the fiber fabric 11 is made of an absorbent composition and is applied and dried. This absorbent composition contains an absorbent polymer and a binder in a ratio of 6:4 to 5:5. Mixed by weight ratio is used.

The absorbent polymer includes polyacryl amide, polyacrylic acid, polyethylene oxide, and polyvinyl alcohol. Through this absorbent polymer, it is possible to achieve the ability to raise moisture from the inner surface (11a) of the fabric body (11) to the outer surface (11b).

In this embodiment, microcapsules containing a phase change material for temperature control may be added to the absorbent composition. The phase change material is also called a phase change material and can be used as a phase change material such as hydrocarbon, paraffin, or polyethylene glycol. In particular, it is preferable to use a phase change material with a melting point of 20 to 39°C. By encapsulating such a phase change material, heat is quickly absorbed and cooling functionality can be provided to the fabric body 11.

Additionally, in this embodiment, sustained-release microcapsules containing natural aroma oil may be added to the absorbent composition. The natural aroma oils include lavender, peppermint, rose, rosemary, eucalyptus, orange, grapefruit, basil, and chamomile.

By making such natural aroma oil into sustained-release microcapsules, it is possible to slowly leak out from the microcapsules even during repeated washing, thereby continuously generating fragrance.

Figure 2 explains the method of forming the water repellent layer pattern 12 and the absorbent layer pattern 13 on the inner and outer surfaces 11a and 11b of the fabric body 11 as described above.

First, a first transfer roll 20 for forming the water-repellent layer pattern 12 on the inner surface 11a of the fabric main body 11, and an absorbent layer pattern 13 on the outer surface 11b of the fabric main body 11. ) Prepare a second transfer roll 30 to form.

A water-repellent layer pattern groove 21 matching the water-repellent layer pattern 12 is formed on the surface of the first transfer roll 20, and a water-repellent layer pattern groove 21 is formed on the surface of the second transfer roll 30, which matches the absorbent layer pattern 13. Absorbing layer pattern grooves 31 are formed by recessing.

Since the relative positional relationship between the water-repellent layer pattern 12 and the absorbent layer pattern 13 printed on both surfaces of the fabric body 11 is important, the water-repellent layer pattern groove 21 and the absorbent layer pattern groove ( 31) is adjusted to match the positional relationship of the patterns 12 and 13, and then in order to prevent slip between the first transfer roll 20 and the second transfer roll 30 during operation. Constrains the relative rotation. For this restraint, methods such as gear combination and timing belt can be applied.

Next, a first coating blade 40 is installed on one upper surface of the first transfer roll 20, and a liquid layer is applied to the surface of the first transfer roll 20 that is abutted through the nozzle portion at the bottom. A water-repellent composition (61) is supplied. Through this, the water-repellent composition is supplied to the water-repellent layer pattern groove 21 on the surface of the first transfer roll 20, and the water-repellent composition is supplied to the inner end of the first coating plate 40 with respect to the rotating first transfer roll 20. The water-repellent composition 61 is removed from the surface of the first transfer roll 20 excluding the water-repellent layer pattern grooves 21 by scraping the surface of the first transfer roll 20 with the blade 41.

Likewise, the second coating blade 50 is installed on one upper surface of the second transfer roll 30, and the liquid absorbent composition 62 is applied to the surface of the second transfer roll 30 that is abutted through the nozzle portion at the bottom. supplies. Through this, the absorbent composition is supplied to the absorbent layer pattern groove 31 on the surface of the second transfer roll 30, and the blade formed on the inner end of the second coating plate 50 with respect to the rotating second transfer roll 30 The absorbent composition 62 is removed from the surface of the second transfer roll 30 excluding the absorbent layer pattern groove 31 by scraping the surface of the second transfer roll 30 at (51).

Accordingly, in the path through which the fabric body 11 passes, the first transfer roll 20 pressing the inner surface 11a and the second transfer roll 30 pressing the outer surface 11b engage with each other and rotate. The water repellent layer pattern 12 can be formed on the inner surface 11a of the fabric main body 11 and the absorbent layer pattern 13 can be formed on the outer surface 11b of the fabric main body 11 at the same time.

Figure 3 is an example of a pattern that can be obtained through the above method. The water-repellent layer pattern 72 formed on the inner surface 71a of the fabric body 71 is a regular hexagon drawn with a line of a certain width W1. It has a regular hexagonal pattern shape obtained by neighboring each side. At this time, the absorption layer pattern 73 formed on the outer surface 71b of the fabric main body 71 is a dot pattern and is formed to be located at the center of the regular hexagon shape of the inner surface 71a. Accordingly, moisture pushed from the inner surface 71a of the fabric main body 71 to the regular hexagonal inner region S by the water-repellent layer pattern 72 is not only absorbed by the fabric main body 71, but also the opposite outer surface 71b. ) is pulled due to the absorption layer pattern 73 formed on the surface and is quickly transferred to the outside, thereby achieving a rapid moisture discharge effect.

What is noteworthy is that, thanks to the contribution of the absorption layer pattern 73, the width W1 of the line forming the water-repellent layer pattern 72 is set narrow, so that the internal area is larger than the area occupied by the water-repellent layer pattern 72. This means that the area occupied by (S) can be formed wider.

Figure 4 is an example of applying a different absorbent layer pattern (73') to the same water-repellent layer pattern (72) as above, and the moisture pushed out to the inner region (S) by the water-repellent layer pattern (72) is more quickly transferred to the outer surface (71b). can be pulled.

The absorbent layer pattern 73' is a regular polygonal pattern in which a plurality of center lines drawn by lines with a width W2 narrower than the line width W1 forming the water repellent layer pattern 72 forms the water repellent layer pattern 72. It is obtained by passing through each center and being equidistant from each other in the circumferential direction.

Meanwhile, the textile fabric 10 manufactured as above is manufactured into a cool-sensitive fabric 100 through the process as shown in FIG. 5. That is, the textile fabric 10 pulled out from the textile fabric roll 91 passes through the bonding liquid applicator 92 and the gravure roll 93, and the bonding liquid is applied to the outer surface at a certain thickness, and then is applied to the rubber pressing roller ( In the process of passing through 94), the waterproof fabric 80 pulled out from the waterproof fabric roll 95 is compressed, and while passing through the heating roller 96, it is heat-compressed and integrated, thereby completing the cool-sensitive fabric 100.

At this time, the bonding liquid layer 14 applied to the outer surface of the textile fabric 10 is impregnated between the absorbent layer patterns 13 as shown in (b) of FIG. 6 and is at the same height as the absorbent layer pattern 13. achieves In addition, the waterproof fabric 80 attached to the outer surface of the textile fabric 10 is formed with a plurality of protrusions 81 uniformly distributed over the entire surface as shown in (c) of FIG. 6, thereby forming a plurality of these. It is attached to the outer surface of the fiber fabric 10 via the protrusion 81 (Figure 6(d)).

Therefore, between the textile fabric 10 and the waterproof fabric 80, an interspace T equal to the thickness of the plurality of protrusions 81 is formed as shown in FIG. 7, and the absorbent layer pattern 13 is formed in the interspace. You will face (T) directly. As a result, the moisture pushed out from the inner surface 11a of the fabric main body 11 to the inner region S by the water-repellent layer pattern 12 is absorbed into the fabric main body 11 and then formed in the absorption layer pattern on the outer surface 11b. Due to (13), it is pulled outward, so that there is room to accommodate it in the interspace (T).

In other words, the cold-sensitive fabric 100 according to an embodiment of the present invention has a moisture absorption function through the fiber fabric 10 through the special combination structure of the fiber fabric 10 and the waterproof fabric 80 as described above, and is also a waterproof fabric. Waterproofing performance can also be achieved through (80).
