활성탄 부직포 필터의 제조방법 {Method for manufacturing nowoven fabrics filter containing active carbon}Process for manufacturing activated carbon nonwoven filter {Method for manufacturing nowoven fabrics filter containing active carbon}

본 발명은 주로 산업 현장에서 사용되는 필터의 여재에 관한 것으로, 특히 활성탄을 함유하는 부직포 필터의 제조방법에 관한 것이다.
TECHNICAL FIELD This invention relates to the filter medium mainly used in the industrial field, and especially relates to the manufacturing method of the nonwoven filter containing activated carbon.

일반적으로 산업현장에서는 분진, 흄, 악취, 유독 개스 기타 작업자에게 유해한 요소들이 많이 발생하기 마련이다. 이때 작업자들은 방진 마스크를 착용하게 되는데, 여기에는 공기를 여과하는데 필요한 방진필터가 적용되어 있다. 통상적으로 방진필터에서는 필터재료로서 PE 또는 PP 등의 부직포가 사용된다.
In general, there are many elements that are harmful to dust, fume, odor, toxic gas and other workers. In this case, workers wear a dust mask, which is equipped with a dust filter necessary to filter air. Usually, in a dustproof filter, nonwoven fabrics, such as PE or PP, are used as a filter material.

필터재료의 방취나 방독을 보강하기 위하여, 상기 부직포에 흡입·흡착력이 우수한 활성탄을 이용하기도 하는데 이를 소위 '활성탄 부직포 필터'라 한다. 전통적으로는 부직포 원단 상에 접착제를 도포하고, 그 위에 활성탄 분말을 분사한 후, 열 또는 프레스로 압착하여, 필터를 완성한다. 이 방법은 부직포에 활성탄을 적용하기에 가장 쉬운 방법이지만, In order to reinforce the deodorization and the detoxification of the filter material, activated carbon having excellent suction and adsorption power may be used for the nonwoven fabric, which is called an activated carbon nonwoven filter. Traditionally, an adhesive is applied on a nonwoven fabric, sprayed with activated carbon powder on it, and then compressed by heat or press to complete the filter. This is the easiest way to apply activated carbon to nonwovens,

1) 그 표면에 입자가 붙는 상태이므로, 사용되는 활성탄의 양이 극히 제한적일 수밖에 없고, 2) 그나마 취급 및 가공시 부직포의 표면으로부터 떨어져 버리기가 쉽다. 3) 또한, 압착 과정에서 활성탄의 원형과 기능의 손상, 손실이 발생하는 등의 문제가 있다.
1) Since the particles adhere to the surface, the amount of activated carbon used is extremely limited, and 2) it is easy to fall off the surface of the nonwoven fabric during handling and processing. 3) In addition, there is a problem such as damage and loss of the original form and function of activated carbon during the pressing process.

이에 활성탄이 부직포 내부에 분산되도록 하는 방법들이 제안되어 있다.
Accordingly, methods for dispersing activated carbon inside the nonwoven fabric have been proposed.

한 방법으로, 공개특허 제2003-54462호에는 부직포 상에 활성탄 분말을 분사한 후 니들펀칭(needle-punching)을 수행하여 분말이 함침되도록 하는 방법이 개시되어 있다. 그러나 이 방법은 활성탄을 상대로 니들링을 하는 자체가 어려울 뿐만 아니라, 당연하게 부직포 원단 및 활성탄에 손상이 유발되며, 활성탄의 분산효과도 사실상 기대하기 어렵다.
In one method, Korean Patent Laid-Open Publication No. 2003-54462 discloses a method of spraying activated carbon powder on a nonwoven fabric and then performing needle punching to impregnate the powder. However, this method is not only difficult to needle the activated carbon itself, but also naturally causes damage to the nonwoven fabric and activated carbon, and the dispersion effect of the activated carbon is virtually difficult to expect.

다른 방법으로, 공개특허 제1996-30973호 및 제2003-54460호에는 접착제 또는 물에 활성탄 분말을 넣고 혼합한 용액에, 부직포를 함침시켜 활성탄을 내부에 분산되도록 하고, 롤러로 압착시킨 후, 건조하는 방법이 개시되어 있다. 위의 방법에 비하면, 이 방법이 활성탄의 분산에 유리할 것으로 보인다. 그러나 여기에는 다음의 중요한 문제들이 있다.
Alternatively, in Korean Patent Nos. 1996-30973 and 2003-54460, activated carbon powder is added to an adhesive or water, and a mixed solution is impregnated with a nonwoven fabric to disperse activated carbon therein, and then compressed with a roller, followed by drying. A method is disclosed. Compared to the above method, this method seems to be advantageous for the dispersion of activated carbon. However, there are the following important issues.

첫째, 활성탄 분말은 표면 세공으로 인하여 우수한 흡입·흡착력을 갖음에 따라, 강제 분산하지 않는 한 용액 상에서 서로 뭉쳐지는 경향이 있으며, 이 상태에서는 부직포를 함침시켜도 활성탄이 고루 분산되지 않는다.First, as the activated carbon powder has excellent suction and adsorption power due to the surface pores, the activated carbon powder tends to agglomerate with each other in a solution unless it is forced to disperse. In this state, the activated carbon is not evenly dispersed even when impregnated with a nonwoven fabric.

둘째, 활성탄 분말은 용액 중에 혼합되어 있지만, 부직포를 함침시켰다가 꺼내면 대부분의 활성탄 분말은 부직포의 내부에 침투되지 않으며, 당연히 표면 쪽에 집중적으로 몰려있게 된다.Second, although the activated carbon powder is mixed in the solution, most of the activated carbon powder does not penetrate the inside of the nonwoven fabric when it is impregnated and taken out of the nonwoven fabric.

셋째, 활성탄은 용액 중에서도 용해되지 않고 분말 상태로 있기 때문에, 예컨대 롤 형태의 부직포가 용액을 통과할 때 앞에서 거의 소진되어 버리므로, 예컨대 필터 블록의 제조에는 적합할 수 있으나, 부직포 원단이 연속으로 공급되는 자동화 공정에 적합하지 않다.Third, since the activated carbon is not dissolved in the solution but in a powder state, for example, the roll-type nonwoven fabric is almost exhausted from the front when passing through the solution, it may be suitable for manufacturing a filter block, for example, but the nonwoven fabric is continuously supplied. Not suitable for automated processes.

넷째, 부직포를 함침 후에는 압착하여 용액을 제거하게 되는데, 이때 부직포에 함침되어 있던 활성탄의 상당량이 함께 제거된다. 또한, 압착에 의한 활성탄의 표면손상 및 기능손실이 유발된다.
Fourth, after impregnating the nonwoven fabric is compressed to remove the solution, at this time, a significant amount of activated carbon impregnated in the nonwoven fabric is removed together. In addition, surface damage and loss of function of activated carbon are caused by pressing.

무엇보다도, 활성탄은 표면 세공으로 인하여 우수한 흡입·흡착력을 갖는 것인데, 접착제 또는 물에 활성탄 분말을 넣고 혼합하는 과정에서 세공의 내부에까지 용액이 완전히 충전되며, 이로써 활성탄 필터의 기능이 현저히 떨어지게 된다. 공개특허 제1996-30973호에서는 이를 방지하기 위하여 접착제에 CMC(carboxy methyl cellulose) 또는 PVA(polyvinyl alcohol)을 혼합한다고 하지만, 공정이 복잡해지는 것은 물론 그 효과가 미약하다.
Above all, activated carbon has excellent suction and adsorption power due to surface pores, and the solution is completely filled into the pores in the process of mixing activated carbon powder in an adhesive or water, thereby significantly reducing the function of the activated carbon filter. In Patent Publication No. 1996-30973, in order to prevent this, the adhesive is mixed with carboxy methyl cellulose (CMC) or polyvinyl alcohol (PVA), but the process is complicated and the effect is weak.

한편, 공개특허 제2003-54460호에서 물은 건조된다고 할 수 있지만, 이 경우 활성탄 분말이 부직포로부터 쉽게 떨어져 버리는 등의 다른 문제를 야기한다.
On the other hand, in the Patent Publication No. 2003-54460 it can be said that the water is dried, but this causes other problems such as the activated carbon powder is easily separated from the nonwoven fabric.

본 발명은 상기한 종래기술에 따른 활성탄 부직포 필터의 문제들을 해결하고자 제안된 것이다. 본 발명의 목적은 부직포 내부에 활성탄이 함침되도록 하되:The present invention is proposed to solve the problems of the activated carbon nonwoven filter according to the prior art.

를 포함하여 이루어진다.
.

상기 제2단계에서 가압은 압착 롤러를 이용하는 한편, 상기 제3단계 및 제4단계는 동시에 이루어질 수 있다.
Pressing in the second step uses a pressing roller, while the third step and the fourth step may be performed simultaneously.

바람직하게 상기 활성탄 부직포 필터 제조방법은:Preferably, the activated carbon nonwoven filter manufacturing method is:

상기 원단의 양측 표면에, 부착된 활성탄 입자를 보호하기 위한 다공성 필름을 공급하는 제5단계;Supplying a porous film to protect the activated carbon particles attached to both surfaces of the fabric;

를 더 포함하여 이루어진다.
.

본 발명은 활성탄 부직포 필터를 제조하는 방법으로서, 부직포 내부에 활성탄이 함침되도록 한다. 특히, 부직포 원단의 내·외부에 접착제 성분이 전체적으로 분포되도록 하고, 일측 표면에서 활성탄을 분사하고 진동을 주어 원단 내부에까지 침착되도록 한다. 이에 따라, The present invention is a method of manufacturing an activated carbon nonwoven filter, and the activated carbon is impregnated into the nonwoven fabric. In particular, the adhesive component is distributed to the inside and outside of the nonwoven fabric as a whole, and activated carbon is sprayed and vibrated from one surface to be deposited to the inside of the fabric.

Features and effects of the 'manufacturing method of the activated carbon nonwoven filter' (hereinafter 'manufacturing method') according to the present invention described above or not described will become more apparent through the following description of the embodiments described with reference to the accompanying drawings.

도 1을 참조하면, 본 발명의 제조방법을 수행하기 위하여 일련의 시스템(10)이 구성된다. 상기 시스템(10)은 차례로 접착제 풀(pool)(11), 압착 롤러(12), 활성탄 분사장치(13), 진동수단(14), 가이드 롤러(15)를 포함하여 구성된다. 롤 형태의 부직포 원단(16)이 길이 방향으로 연속적으로 공급되고, 이 시스템(10)의 상기한 요소(11~15)를 차례로 거치면서, 본 발명에 따른 활성탄 부직포 필터(17)가 획득되는 것이다.
Referring to Figure 1, a series of systems 10 are constructed to perform the manufacturing method of the present invention. The system 10 in turn comprises an adhesive pool 11, a compacting roller 12, an activated carbon injector 13, a vibrating means 14 and a guide roller 15. The rolled nonwoven fabric 16 is continuously supplied in the longitudinal direction, and the activated carbon nonwoven fabric filter 17 according to the present invention is obtained while sequentially passing through the above-described elements 11 to 15 of the system 10. .

이하에서는 도 1 및 도 2를 참조하여, 상기 시스템(10)을 이용하여 활성탄 부직포 필터(17)를 제조하는 방법을 설명한다.
1 and 2, a method of manufacturing the activated carbon nonwoven filter 17 using the system 10 will be described.

[제1단계: 접착제 용액 [Step 1: Adhesive Solution 함침Impregnation ]]

이 단계는 부직포 원단(16)의 내·외부 전체에 접착제(18)가 미치도록 하는 단계이다. 구체적으로는, 롤 형태의 부직포 원단(16)을 길이 방향으로 공급하면서 접착제 풀(11) 내부의 액상 접착제(18)에 함침시켜, 원단(16) 내부에 용액이 침투되도록 한 후, 외부로 배출한다.
This step is such that the adhesive 18 extends to the entire inside and outside of the nonwoven fabric 16. Specifically, while impregnating the liquid adhesive 18 inside the adhesive pool 11 while supplying the roll-shaped nonwoven fabric 16 in the lengthwise direction, the solution penetrates into the fabric 16 and then discharged to the outside. do.

이 방법은 접착제(18) 용액이 원단(16)에 충분히 침투 및 분산되게 하는 통상의 방법이지만, 본 발명에서도 유용하게 적용된다. 한편, 상기 접착제(18)로는 바람직하게 수성계 접착제인 EVA(ethylene vinyl acetate)계 접착제가 사용되지만, 알려진 다른 재료가 사용될 수도 있다.
This method is a conventional method for sufficiently infiltrating and dispersing the solution of the adhesive 18 into the fabric 16, but is also usefully applied in the present invention. Meanwhile, as the adhesive 18, an EVA (ethylene vinyl acetate) adhesive, which is preferably an aqueous adhesive, is used, but other known materials may be used.

[제2단계: 수분 제거][Step 2: Remove Moisture]

이 단계는 제1단계에서 배출된 원단(16)을 가압하여, 원단(16) 중에 함유된 접착제(18) 용액을 짜내는 것이다. 상기한 제1단계에서, 원단(16)은 접착제 용액에 함침되어 과도한 양의 용액을 함유하게 된다. 이는 용액의 전반적인 분포에는 도움이 되지만, 그 상태로는 후술하는 활성탄의 분산 및 건조 등의 과정에는 비효율적인 요인이 된다.
This step is to squeeze the solution of the adhesive 18 contained in the fabric 16 by pressing the fabric 16 discharged in the first step. In the first step described above, the fabric 16 is impregnated with an adhesive solution to contain an excessive amount of solution. This is helpful for the overall distribution of the solution, but in that state is an inefficient factor in the process of dispersion and drying of the activated carbon described later.

이에 상기 원단(16)으로부터 불필요한 또는 필요 이상의 용액을 제거하는 것이다. 이 단계에서 원단(16)은 압착 롤러(12)를 통과하게 되며, 그러면 상기 원단(16)으로부터 접착제의 용액 수분이 제거되고, 원단(16)의 표면을 비롯하여, 내부 공극의 주변에 단지 접착 성분만이 잔존하게 되는 것이다.
This removes unnecessary or necessary solutions from the fabric 16. In this step, the fabric 16 passes through the compression roller 12, which removes the solution moisture of the adhesive from the fabric 16, and only adheres to the periphery of the interior voids, including the surface of the fabric 16. Only will remain.

[제3단계: 활성탄 분사][Step 3: Activated Carbon Injection]

이 단계는 분사장치(13)을 이용하여, 상기 원단(16)의 표면에 활성탄을 분사하는 단계이다. 활성탄은 원단(16)의 표면에 가능한 고르게 분사되어야 할 것이지만, 본 발명에서는 다음 단계에서 '진동'을 수반하므로, 활성탄 분사시 어느 정도의 뭉침 현상은 다음 단계에서 해결될 수 있다.
This step is a step of spraying activated carbon on the surface of the fabric 16, using the injector (13). Activated carbon should be sprayed on the surface of the fabric 16 as evenly as possible, but in the present invention is accompanied by a 'vibration' in the next step, some coalescence phenomenon during the activated carbon injection can be solved in the next step.

본 발명은 진동에 의한 활성탄의 강하 및 침착을 유도하는 것이므로, 상기한 활성탄 분사는 원단(16)의 상측 표면에만 하는 것으로 족하다.
Since the present invention induces the drop and deposition of activated carbon by vibration, the above-mentioned activated carbon injection is sufficient to be performed only on the upper surface of the fabric 16.

[제4단계: 활성탄 침착][Step 4: Deposition of Activated Carbon]

이 단계는, 상기 원단(16)에 진동을 가하여 상기 활성탄 입자가 원단(16) 표면으로부터 내부의 공극에 침착되도록 하는 단계이다. 전술한 바와 같이, 본 발명은 진동에 의한 활성탄의 강하 및 침착을 유도하는 것이다. 진동수단(14)으로서 진동 모터가 이용될 수 있다. 또한, 이 단계는 상기한 제3단계 활성탄 분사와 동시에 이루어질 수 있다.
This step is a step of applying vibration to the fabric 16 so that the activated carbon particles are deposited in the interior voids from the fabric 16 surface. As described above, the present invention induces the drop and deposition of activated carbon by vibration. As the vibration means 14, a vibration motor can be used. In addition, this step may be performed simultaneously with the above-described third step activated carbon injection.

이 경우, 원단(16)의 표면에 활성탄 분사하는 동시에 원단(16)에 진동을 가함으로써, 활성탄의 분사, 강하, 침착이 한꺼번에 수행되는 것이다.
In this case, by spraying activated carbon on the surface of the fabric 16 and applying vibration to the fabric 16, spraying, dropping, and deposition of the activated carbon are performed all at once.

상기한 제2단계에서 원단(16)으로부터 접착제(18) 용액의 수분이 제거되고 나면, 원단(16)의 표면 및 내부 공극의 주변에 접착 성분이 남아있다. 그리하여 이 단계에서 활성탄 입자들은 다른 물리적 힘의 접촉 없이, 진동에 의하여 자연 강하하고 그에 따라 원단(16)의 내·외부 공극에 침착되고 안정화될 수 있는 것이다. 이때 활성탄 입자들은 단지 그 표면의 일부만이 접착 성분과 접촉하며, 적어도 그 표면 세공(細孔)이 접착제 등의 용액으로 충전되지는 않는다.
After the moisture of the adhesive 18 solution is removed from the fabric 16 in the second step described above, the adhesive component remains on the surface of the fabric 16 and around the inner pores. Thus, at this stage, the activated carbon particles can naturally fall by vibration and be deposited and stabilized in the inner and outer pores of the fabric 16 without contacting other physical forces. At this time, activated carbon particles only have a part of the surface in contact with the adhesive component, and at least the surface pores are not filled with a solution such as an adhesive.

따라서 활성탄 입자들은 외부의 물리적 힘에 의하여 손상되지 않으며, 기능의 발현이 접착제 등 용액에 의하여 방해되지 않는다.
Therefore, activated carbon particles are not damaged by external physical force, and the expression of the function is not hindered by a solution such as an adhesive.

[제5단계: 보호 필름][Step 5: Protective film]

이 단계는, 상기 원단(16)의 양측 표면에 다공성 필름(19)을 공급하는 단계이다. 상기 활성탄은 접착제를 이용하여 부착되지만, 표면 접촉에 의하여 쉽게 떨어져 버리는 재료이다. 따라서 표면에 부착된 활성탄 입자를 보호하기 위하여, 다공성 필름(19)을 공급하는 것이다.
This step is to supply the porous film 19 to both surfaces of the fabric (16). The activated carbon is a material attached using an adhesive, but is easily peeled off by surface contact. Therefore, in order to protect the activated carbon particles attached to the surface, the porous film 19 is supplied.

본 발명에 따르면 원단(16)에 대한 활성탄의 침착 정도가 원단(16)의 전구역에 이르므로, 바람직하게 원단(16)의 양측 표면에 다공성 필름(19)을 공급한다. 이 필름으로서 필터 저항이 적은 PE, PP 필름 등이 적합하며, 가이드 롤러(15)를 통하여 원단(16)의 양면에 제공된다.
According to the present invention, since the degree of deposition of activated carbon on the fabric 16 reaches the entire region of the fabric 16, the porous film 19 is preferably supplied to both surfaces of the fabric 16. As this film, PE, PP film, etc. with little filter resistance are suitable, and it is provided in both surfaces of the original fabric 16 through the guide roller 15. As shown in FIG.

이상의 제1단계 내지 제5단계를 거쳐, 본 발명의 활성탄 부직포 필터(17)를 제조한다. 이 활성탄 부직포 필터(17)는 자동화 공정에서, 도시된 바와 같은 롤 형태로 권취될 것이다. 그리고 이 부직포 필터(17)가 실제로 방진 마스크 등에 적용되는 경우, 상기한 다공성 필름(19)은 제거되거나 또는 방진 필터층으로서 그대로 사용될 것이다.
Through the above first to fifth steps, the activated carbon nonwoven filter 17 of the present invention is manufactured. This activated carbon nonwoven filter 17 will be wound in a roll form as shown in the automated process. And if this nonwoven filter 17 is actually applied to a dust mask or the like, the porous film 19 described above will be removed or used as a dust filter layer as it is.

도 3을 참조하면, 본 발명의 활성탄 부직포 필터(17)는 활성탄이 함침된 부직포 원단(16)의 상·하면에 각각 다공성 필름(19)이 배치되어 이루어진다. 상기 필름(19)은 원단(16)에 비하여 얇은 필름이며, 이는 필터(17)의 공기저항을 가능한 줄이고자 한 것이다.
Referring to FIG. 3, the activated carbon nonwoven fabric filter 17 of the present invention includes a porous film 19 disposed on upper and lower surfaces of the nonwoven fabric 16 impregnated with activated carbon, respectively. The film 19 is a thin film compared to the fabric 16, which is intended to reduce the air resistance of the filter 17 as much as possible.
