The activated carbon 5 of the adsorption layer is in a spherical shape, and is in close contact with the outer circumferential surfaces thereof.

As shown in FIG. 1 (b), another adhesive paste (8) is applied to the supporting fabric 7a, as shown in FIG. 1 (b) ) Is applied, the bead type activated carbon 9 is attached, and the cover end 7b is covered with the activated carbon 9.

However, since the activated carbon of the adsorbing layer is provided in a bead shape (spherical shape), the outer circumferential surfaces of the adsorbing layers are brought into close contact with each other by virtue of the diameter H, , The folding curvature becomes larger by the spherical structure when folding the above-mentioned CBR, and accordingly, when the user presses while the joints are folded at the time of activation, the activated carbons contacting each other are broken by the pressing force There was a possibility of damage.

Korean Patent No. 10-1047944

Hereinafter, the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 2 to 4, the raw fabric for protecting the NBC according to the first embodiment of the present invention comprises a first layer 10, an adsorption layer 20 fixed to the first layer 10, And a second layer 30 that shields the layer 20.

Referring to FIGS. 2 to 4, the first layer 10 provides a base for fixing the bottom of the adsorption layer 20, as shown in FIG. (Not shown) for adhering and fixing the adsorption layer 20 to the surface on which the adsorption layer 20 is disposed. At this time, the first layer 10 is coated with an adhesive in any one of gravure, dot, and mesh.

2 and 3, the adsorption layer 20 includes a plurality of activated carbons 21 adhered and fixed to the surface of the first layer 10 to which an adhesive is applied.

The activated carbon 21 of the adsorption layer 20 is hemispherical and one side forming a plane is fixed to the surface of the first layer 10 and the other side forming the spherical surface is fixed to the second layer 30, So that the outer circumferential surfaces of the activated carbon 21 are in contact with each other.

The activated carbon 21 may be formed (attached) on the surface of the first layer 10 by a dot printing method (a point-like pattern is formed on the surface of the raw fabric), and in some cases, (Adhered). Therefore, the diameter H of the activated carbon 21 is not formed, and the radius h substantially equivalent to the conventional diameter is formed. That is, the height of the activated carbon 21 is lower than the conventional one.

The activated carbons 21 are formed on the first layer 10 so that the outer circumferential surfaces of the activated carbon 21 are in close contact with each other as shown during molding, that is, during printing. Therefore, the activated carbon 21 is formed on the first layer 10 with almost no gaps and adsorbs most of the toxic substances introduced therein.

Here, the dot printing method described above may be applied to the surface of the first layer 10 on which the adhesive is applied, as in the case of dot printing, in the form of a colloidal or paste-like activated carbon material. At this time, the above-mentioned activated carbon raw material is the same raw material as the raw material for producing the spherical activated carbon described in the prior art. That is, the activated carbon raw material is a raw material in the form of a colloid or a paste prepared for preparing conventional spherical activated carbon. The activated carbon raw material is a technique that a person skilled in the art can easily implement through conventional spherical activated carbon, and a detailed description thereof will be omitted.

Alternatively, the dot printing method may be applied to a first layer 10 coated with an adhesive such that the activated carbon 21 attached to a film or a mold, which is manufactured in a semi-spherical shape or the like as described later, To the first layer 10 in the form of a dot.

However, the dot printing method is not limited to the above-mentioned method insofar as the activated carbon 21 is attached to the first layer 10 at a time and can be attached to the first layer 10 in the form of a dot. However, the dot printing method is a method in which the activated carbon 21 is attached to the cloth as if the ink is printed in the form of dots, so that the attachment surface of the activated carbon 21 attached to the first layer 10 forms a plane , And any method can be used as long as the opposite side is protruded and attached. Such a dot printing method is a technique that can be easily implemented by those skilled in the art, and thus a detailed description thereof will be omitted.

2 and 3, the second layer 30 has a flat structure in which an adhesive agent (not shown) is applied on the bottom surface of the adsorbing layer 20 to shield the adsorbing layer 20 . At this time, the second layer 30 is coated with an adhesive in any one of gravure, dot and mesh methods, and is attached to the activated carbon 21 of the adsorption layer 20 by an adhesive.

The first layer 10 and the second layer 30 may be made of a nonwoven fabric having excellent stretchability such as knitted fabric, Teflon or gore-tex fabric or cushion, or PTFE or EPTFE Either a material film or a fabric made of a membrane made of such material may be selected and applied differently from each other.

For example, if the first layer 10 is cut, the second layer 30 may be a nonwoven fabric, which is one of the remaining layers except the knitted fabric.

Here, the fabric having excellent stretchability described above is smoothly expanded and contracted during the wearer's work, thereby improving the wearability. The nonwoven fabric prevents the activated carbon 21 from being broken through the cushion when the first layer 10 is bent. In addition, PTFE or EPTFE blocks toxic substances, especially liquid toxic substances, that permeate through the activated carbon 21.

5 and 6, the second embodiment of the present invention is constructed in the same manner as the first embodiment described above, except that the adsorbent layer 20 is additionally provided with toxic substances Is further comprised of the additional adsorbent material for adsorbing the adsorbent. Therefore, only the difference will be described as follows.

The additional adsorbent material may include a plurality of adsorbent layers disposed on the other side of the first layer 10 in a state of being opposed to the activated carbon 21 of the adsorbent layer 20 fixed to one side of the first layer 10. [ A second adsorption layer 40 composed of activated carbon 41 for adsorbing toxic substances and a third layer 50 for shielding and protecting the second adsorption layer 40.

The activated carbons 41 may be arranged concentrically with respect to the first layer 10 as shown in FIG. In this case, the activated carbon 41 forms a spherical shape substantially as in the prior art. However, since the activated carbon 41 and the activated carbon 21 and 41 fixed to the upper and lower portions of the first layer 10 are divided by the first layer 10, Even if the layer 10 is folded, it does not come into surface contact with the adjacent activated carbons 21 and 41, but comes into line contact or point contact. That is, the first layer 10 divides the activated carbon 21 on the upper side and the activated carbon 41 on the lower side to prevent the activated carbon 21 or 41 from forming a complete sphere, , 41 are prevented from being in surface contact with each other. Therefore, the activated carbon 21, 41 is prevented from being broken at the time of folding.

The third layer 50 may be made of the knit, teflon, gore-tex or nonwoven fabric The first layer 10 or the second layer 30 is made of a PTFE or EPTFE material having excellent performance for blocking the penetration of toxic substances or a fabric made of such a membrane. For example, when the first layer 10 is knitted, the third layer 50 may apply any one of the remaining layers except the knitted layer.

The third layer (50) is coated with an adhesive in the same manner as the second layer (30) described above. Therefore, the third layer (50) is attached to the activated carbon (41) on the lower side through an adhesive.

Here, a PTFE or EPTFE film or a fabric made of such a membrane having excellent ability to block penetration of the knit, teflon, gore-tex, or non-woven fabric or toxic substances described above may be stretched, infiltrated with a cushion or a toxic substance And the like.

7 and 8, the third embodiment of the present invention is the same as the second embodiment described above except that the hemispherical shape having the hemispherical shape fixed to the bottom surface of the first layer 10 And the activated carbon 41 is fixed in an alternating manner with the activated carbon 21 fixed to the upper portion of the first layer 10. Therefore, only the difference will be described as follows.

As shown in FIG. 8, the activated carbons 21 and 41 are arranged corresponding to the upper and lower chambers with respect to the first layer 10, but they are eccentrically and printed in a mutually offset form. In this case, the activated carbons 41 fixed to the lower part of the first layer 10 may contact the contact surface of the activated carbon 21 fixed to the upper part of the first layer 10, Shielded from the bottom. Therefore, the activated carbon 41 fixed to the lower part of the first layer 10 can absorb toxic substances penetrating between the activated carbon 21 on the upper side.

Meanwhile, the activated carbon 21, 41 may have various shapes such as a truncated cone shape within a range where the outer circumferential surfaces of the activated carbon 21 and 41 come into close contact with each other by point contact or line contact. The activated carbons 21 and 41 may be manufactured by printing in a hemispherical shape in which the bottom surface attached to the first layer 10 is formed in a square shape. In this case, since the bottom surfaces of the activated carbons 21 and 471 are rectangular, it is possible to prevent almost completely gaps between the first layers 10 when they are in close contact with each other.

In addition, the fabric having excellent elasticity may be selected from a variety of materials having excellent stretchability other than the knit, Teflon, and Gore-Tex.

In addition, the first layer 10, the second layer 30 and the third layer 50 may be coated with an adhesive (not shown) in any one of gravure, dot and mesh methods, Thereby reducing the weight of the fabric.

On the other hand, in the protection of the CBR (not shown) of the present invention, it is possible to fabricate an undercoat or a hood or a mask using the fabrics of various embodiments as described above.

A method of fabricating the NBC protective fabric according to an embodiment of the present invention will now be described.

The first layer 10 is fabricated by cutting any one of the knitted fabric, the nonwoven fabric, the Teflon, and the Gore-Tex fabric. The second layer 30 is fabricated by cutting a selected one of the non-selected fabrics from among the fabrics.

Then, an adhesive is applied to the surface of each of the first and second layers (10, 30) in a gravure, dot and mesh manner.

In this state, activated carbon 21 having a plurality of hemispherical shapes is formed on the surface of the first layer 10 by the dot printing method while the outer peripheral surfaces of the activated carbon 21 are in contact with each other.

Then, the second layer 30 is shielded and adhered to the upper surface of the adsorption layer 20 made of the plurality of activated carbon 21, thereby completing the fabric according to the first embodiment.

On the other hand, the second adsorption layer 40 and the third layer 50 are added to the bottom surface of the first layer 10 by mirror-symmetry or offset mirror symmetry, You can also finish the fabric. That is, the activated carbon 41 may be attached below the first layer 10, and the third layer 50 may be attached to complete the fabric according to the second or third embodiment.

At this time, the activated carbon 41 of the added second adsorption layer 40 is adhered on the concentric axis in a mirror-symmetrical state with the activated carbon 21 on the upper side to form a substantially spherical shape, , 41 may be eccentric to each other to form an eccentric slanted sphere shape.

Meanwhile, the unshown NBC protection can be manufactured using the fabrics of these various embodiments.

As described above, the activated carbon 21 of the adsorbing layer 20 disposed between the first and second layers 10 and 30 is hemispherically shaped so that the outer circumferential surfaces The folded curvature of the fabric is made to be half as compared with the conventional one by making it come into close contact with the point contact or the line contact so as to prevent the damage of the activated carbon when the fabric is folded and at the same time, will be.

The second adsorption layer (40) and the third layer (50) are further provided on the bottom surface of the first layer (10), so that the adsorption layer can be reinforced and the adsorption performance can be improved .

The first, second and third layers (10, 30, 50) are selectively applied to any one of knit, nonwoven fabric, Teflon, and Gore-Tex so that the stretchability of the fabric is improved, so that the activated carbon is doubly superimposed Even if the contact area becomes large, the fabric can be easily folded due to the elasticity of the fabric, and the damage of the activated carbon can be prevented.

In addition, since the first, second, and third layers (10, 30, 50) are coated with the adhesive in any one of the gravure, dot, and mesh methods, the weight of the fabric can be minimized, It will be possible to provide sex.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It should be understood that all of the techniques that can be easily changed and used by those skilled in the art are included in the technical scope of the present invention.
