Description

FIELD OF THE INVENTION [0001] The present invention relates to a method of manufacturing a fabric for protecting a CBC,

More particularly, the present invention relates to a method of manufacturing a fabric for protecting a CBC, and more particularly, to a method of fabricating a fabric for protecting a CBC by using an air-catalyzing function, Adsorption of substances - Decomposition of harmful substances by air catalyst and decomposition of harmful substances adsorbed on activated carbon, which are manifested even in the absence of light - Method of fabricating protective clothing for CBC with repetitive function of recovery of activated carbon and protective clothing for CBC .

The development and complexity of the industry and the danger of war by international disputes are increasing day by day.

Particularly, some terrorist groups are in semi-national form, so they are not only threats to society as a whole but also attacks of terrorist groups by chemical and biology, outbreak of war, The need for protective coatings is increasing.

Until now, the protective clothing of CBR has been generally active in its performance, so it plays a role of simply adsorbing chemical substances coming into the inside of clothes from outside when wearing clothes.

As a method of this adsorption, products using porous activated carbon (spherical granule type) or porous activated carbon fiber (ACF: Activated Carbon Fabric) have been applied as disclosed in Korean Patent Application Nos. 1020140037934, 1020140122656 and 1020097022491.

However, since this product exerts its performance by adsorption using the fine surface area of activated carbon, even if it is not actually worn, the porous surface adsorbs organic dust or chemicals generated in the air or clothes itself It has a fatal disadvantage that its function is degraded.

On the other hand, such a product is disadvantageous in that when it is used in a place where a pollutant is present, the performance of the adsorption is saturated, or its function is rapidly deteriorated, so that it can not be used almost once if it is used once. In addition, even after one use, the wear time is prolonged, and after the performance of the adsorption is saturated, the wearer is at risk of continuing wearing even though the function is lost.

As a method of solving such a problem, there is a patent application No. 10-2009-07022491 using inorganic matter, but the adsorption of harmful substances by inorganic substances is weaker than the existing methods and is not used at present.

Particularly, when a group or gel method is used, due to the nature of the inorganic substance, the adhesive force on the surface of the clothes is weak, and it is difficult to exhibit the actual function for a long time.

Techniques for improving the function by forming five or more complex layers including a carbon layer as a more complicated technique have been proposed in Patent Application No. 10-2010-0084940 and the like. This technology is a technique in which a detoxifying catalyst containing a photocatalyst is used as a nano- A catalyst for detoxification comprising a photocatalyst is coated on a nano-sterilized fiber layer, and a nano-sterilized fiber layer is coated with a detoxifying catalyst containing a nanoparticle-containing photocatalyst And the mixture is applied to the NBC protective fabric.

This technology claims that it decomposes harmful substances by the ionization of metal oxide by light using photocatalyst, and this catalyst proposes a catalyst that acts under ultraviolet rays. However, there is no ultraviolet ray or general light in the inside of clothes Therefore, there is a problem that the function can not be exerted.

The present invention has been proposed in view of this, and it is an object of the present invention to provide a fabric for protecting a CBC, which is a semi-permanent decomposition function of harmful substances, in a darkroom, that is, inside a garment, using a new air ion catalytic technique that does not use photocatalyst technology And to provide a clothes for CBR use.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a NBC protective fabric according to the present invention. FIG.
2 is a sectional view of a NBC protective fabric according to another embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the attached drawings.

The present invention is to produce a fabric for protecting CBR by fusing the function of an air catalyst 20 in which a function of a catalyst is manifested even in a dark place without light to the activated carbon fiber 10, (20) coated on the surface of the nonwoven fabric (30), or coating the air catalyst (20) on the surface of the nonwoven fabric (30) and laminating it with the activated carbon fiber (10).

The air catalyst 20 applied to the present invention comprises a titanium dioxide component that generates hydroxy radical (OH - ) and hydrogen peroxide (H 2 O 2 ) in water molecules and a titanium dioxide component that repeatedly generates potassium and hydrogen peroxide in the form of hydroxyradicals, The air catalyst 20 should be dispersed in water so as to be smoothly coated on the activated carbon fiber 10 as a fabric for protecting CBR. The potassium reacts with water explosively, Potassium oxide, potassium oxide, is applied so that it can be dispersed.

That is, it is a well-known fact that the elemental symbol K, potassium, contains a trace amount of the isotope Potassium-40, which is about 0.0117% of the natural potassium.

Potassium containing this isotope attacks the water in the air in the natural world, resulting in the formation of hydroxy radicals (OH - ) and hydrogen peroxide (H 2 O 2 ) in water molecules.

At this time, the generated hydrogen peroxide reacts repeatedly with the anion generation reaction that generates the hydroxyl radical again by the transition metal titanium dioxide.

In the present invention, an air catalyst 20 is prepared by mixing potassium oxide and titanium dioxide so that the radical generating ability of potassium and the catalytic dynamics of titanium dioxide are sequentially expressed. In the air catalyst 20, In consideration of the importance of the Fenton reaction, which is a strong hydrogen peroxide decomposition reaction of titanium dioxide, the content of potassium oxide is 10 to 30 wt% and the amount of titanium dioxide is 70 to 90 wt% in the air catalyst 20 . If potassium oxide is less than 10 wt% of the total amount, generation of hydroxy radical and hydrogen peroxide is insufficient from the moisture in the air, and if it exceeds 30 wt%, the content of titanium dioxide is relatively decreased, And the generation thereof becomes insufficient.

The particle size of potassium oxide and titanium dioxide may be as small as possible to be coated on the inside of the activated carbon fiber which is the fabric for protecting CBR. If the particle size is too small, the coating will not be able to be coated and will escape from the fabric. It is preferable that the particle size of potassium oxide and titanium dioxide is 1 to 100 nm.

The air catalyst 20 made of potassium oxide and titanium dioxide is uniformly dispersed in water and then immersed in the activated carbon fiber 10 constituting the fabric for protecting the CBR. The water temperature at this time is such that potassium oxide and titanium dioxide are smoothly It is preferable to maintain the temperature at 80 to 100 ° C. so that the air catalyst 20 can be dissolved and dispersed in water. The air catalyst 20 is preferably added in an amount of 10 to 20 parts by weight based on 100 parts by weight of water in consideration of saturation.

When the activated carbon fiber 10 is immersed in water and taken out after about 20 to 30 minutes and dried at a high temperature, potassium oxide and titanium dioxide constituting the air catalyst 20 are coated on the activated carbon fiber 10, The drying temperature is maintained at 80 to 100 ° C so that the air catalyst 20 can be firmly fixed to the activated carbon fiber 10 as a raw fabric for protecting the CBR.

In the meantime, the present invention can be configured such that the nonwoven fabric 30 is coated with the activated carbon fiber 10, which is a raw fabric for the CBR, while the air catalyst 20 is coated on the nonwoven fabric 30. In this case, In place of immersing the activated carbon fiber 10 in the water in which the air catalyst 20 is dispersed, the nonwoven fabric 30 is dipped in the water in which the air catalyst 20 is dispersed and dried under the same conditions as above, (10) to fabricate the NBC protective fabric.

Then, the CBR protective clothing is manufactured using the CBR protective fabric.

As described above, the fabric for protecting the CBR can generate water (H 2 O) in the air as hydroxy radical and hydrogen peroxide even in the absence of light, and the titanium dioxide component can convert hydrogen peroxide into hydrogen radical The anion generation reaction which generates repetitive generation is caused, and the bacterial or organic compound can be decomposed by the ionized anion.

Therefore, even if the chemical protective clothing according to the present invention is worn in a place without light, it is possible to prevent harmful substances from entering the air catalyst 20, The activated carbon fiber 10 has a repetitive function of decomposing harmful substances caused by the decomposition of the activated carbon fibers 10 and decomposing harmful substances adsorbed on the activated carbon and restoring the function of the activated carbon. Since the airgel catalyst 20 is coated on the bonded nonwoven fabric 30, the decomposition function of the harmful substances in the absence of light can be continuously performed.

The following is a test result of the fabric for protecting CBR according to the present invention.

Test method: Gastec detector tube method

① A fabric (size: 297 mm × 210 mm) consisting of an activated carbon fiber (10) fabric (SPUN type with a thickness of 1 mm) and a polyethylene [PE] nonwoven fabric (30) 5l Tedlar After injecting the test gas (Formaldehyde, Ammonia, Trimethylamine) into the bag and sealing it, the decomposition performance of the above three organic substances was tested in a dark room without light.

(2) The coating solution was dipped in a potassium compound (exhibiting a catalytic function in the air without light in the air) and an air catalyst 20 (20 wt% in solute) containing titanium dioxide, followed by roll quenching, After drying, it was used.

③ After standing for 60 to 180 minutes at room temperature, the gas was measured using a gas detector tube. The results are shown in Table 1 above. The temperature is 25 ° C and the humidity is 60%.

[Example 2]

The air catalyst 20 was coated on one side of an ACF fabric (SPUN type having a thickness of 1 mm) as in Example 1 by spraying method and dried at 80 DEG C to prepare a fabric (size: 297 mm x 210 mm) 5l Tedlar, the test gas (Formaldehyde, Ammonia, Trimethylamine) was injected into the bag, and after sealing, the decomposition performance of the above three organic substances was tested in a dark room without light. As a result, the air catalyst 20 of Example 1 The coated nonwoven fabric 30 exhibited a decomposition effect similar to that of the activated carbon fiber 10 fabric.

[Example 3]

In Example 1, spraying the titanium dioxide as a photocatalyst onto the activated carbon fiber 10, injecting the organic compound test gas (formaldehyde, ammonia, and trimethylamine), sealing it, and then decomposing the three organic materials As a result of the test, the test organoleptic compound showed almost no decomposition effect at 180 minutes as in the case of the air catalyst (20), although the decomposition effect was similar to or slightly similar to that of the activated carbon fiber (10) alone.

As shown in the above Experimental Example, it can be seen that the carbon nanofiber protective fabric according to the present invention has the best ability to decompose noxious gas of the activated carbon fiber coated with the air catalyst 20 made of a mixture of potassium compound and titanium dioxide. The constructed CBC protective clothing is capable of continuously decomposing bacteria and various harmful substances even in the absence of light.

In addition, the activated carbon fiber 10 applied to the chemical protective clothing is characterized in that the powder is blown or broken due to the characteristics of the product. When potassium oxide and titanium dioxide, which form the air catalyst 20, are coated on the surface, The organic material adsorbed on the activated carbon fibers 10 by the radical ions generated by the air catalyst 20 coated on the porous fibers is continuously decomposed The time for the characteristic action of the protective clothing becomes longer or the complete decomposition becomes possible.

In order to realize the effect of the air catalyst 20 in the present invention, the air catalyst 20 is coated on the nonwoven fabric 30 rather than directly coating the air catalyst 20 on the surface of the activated carbon fiber 10, It is preferable to use it in combination with the fibers 10.

As a result of investigating the antimicrobial activity of the air catalyst (20), it was confirmed that there was no fungal growth due to the radical activity generated in a large amount in the dark room.

This results in the generation of hydroxy radicals and hydrogen peroxide in the air in the dark room by the potassium compound forming the air catalyst 20 and the generation of hydrogen radicals repeatedly from hydrogen peroxide through titanium dioxide, The antimicrobial effect is shown by breaking down the cell membrane of the fungus by oxidative decomposition and completely killing it.

Therefore, in the conventional protective clothing, it is impossible to prevent the smell of the mold or the adsorption capacity of the activated carbon fiber 10 from being generated due to the generation of fungi upon permeation of water, but according to the present invention, So that the functionality as a garment can be further improved.
