이와 같은 종래의 문제점을 해결하기 위한 본 발명은 활성탄소섬유의 접착을 위해 PVA(Polyvinyl Alcohol)을 사용하지 않고 뽕나무 인피섬유를 이용하여 물성이 우수하고 높은 비표면적을 갖는 뽕나무 인피섬유를 이용한 필터 및 그 제조방법을 제공함에 그 목적이 있다.The present invention for solving the problems of the prior art does not use PVA (Polyvinyl Alcohol) for adhesion of activated carbon fibers, but uses mulberry bast fibers to provide a filter using mulberry bast fibers having excellent physical properties and a high specific surface area, and An object of the present invention is to provide a method for manufacturing the same.

상기와 같은 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

활성탄소섬유와 뽕나무 인피섬유가 포함된 펄프 슬러리를 습식초지하여 웹을 형성한 후 건조하여 제조하는 것을 특징으로 하는 뽕나무 인피섬유를 이용한 필터의 제조방법을 제공한다.There is provided a method for manufacturing a filter using mulberry bast fibers, characterized in that the pulp slurry containing activated carbon fibers and mulberry bast fibers is wet-papered to form a web, and then dried and manufactured.

그리고 상기 활성탄소섬유의 섬유장은 2 내지 4mm이고, 상기 뽕나무 인피섬유의 섬유장은 7 내지 12mm인 것이 바람직하다.And it is preferable that the fiber length of the activated carbon fiber is 2 to 4 mm, and the fiber length of the mulberry bast fiber is 7 to 12 mm.

상기 펄프 슬러리에는 상기 활성탄소섬유 95중량%와 뽕나무 인피섬유 5중량%가 혼합되어 이루어지는 것이 좋다.It is preferable that 95% by weight of the activated carbon fiber and 5% by weight of the mulberry bast fiber are mixed in the pulp slurry.

상기 웹에 나노셀룰로오스를 처리한 후 건조하는 것이 좋고, 특히 상기 웹에 0.1 wt%농도의 나노셀룰로오스를 처리한 후 건조하는 것이 바람직하다.It is preferable to dry the web after treating the nanocellulose, and in particular, it is preferable to dry the web after treating the nanocellulose with a concentration of 0.1 wt%.

아울러, 본 발명은 상기 제조방법에 의해 제조된 것을 특징으로 하는 뽕나무 인피섬유를 이용한 필터를 제공한다.In addition, the present invention provides a filter using a mulberry bast fiber, characterized in that manufactured by the above manufacturing method.

본 발명은 활성탄소섬유와 뽕나무 인피섬유가 포함된 펄프 슬러리를 습식초지하여 웹을 형성한 후 건조하여 제조함으로서, 뽕나무 인피섬유의 수소결합에 의해 활성탄소섬유 간에 결합력이 부여되어 물성이 우수하고, PVA 등의 바인더를 사용하지 않음으로서 활성탄소섬유의 공극이 막히지 않고, 비표면적이 우수한 필터를 제조할 수 있는 효과가 있다.The present invention is produced by wet papermaking a pulp slurry containing activated carbon fibers and mulberry bast fibers to form a web, and then drying them. By not using a binder such as PVA, the pores of the activated carbon fibers are not blocked and a filter having an excellent specific surface area can be manufactured.

이하, 본 발명의 뽕나무 인피섬유를 이용한 필터의 제조방법에 대해 상세히 설명하면 다음과 같다.Hereinafter, the manufacturing method of the filter using the mulberry bast fiber of the present invention will be described in detail as follows.

본 발명의 뽕나무 인피섬유를 이용한 필터의 제조방법은 활성탄소섬유와 뽕나무 인피섬유가 포함된 펄프 슬러리를 습식초지하여 웹을 형성한 후 건조하여 제조한다.In the method for manufacturing a filter using mulberry bast fibers of the present invention, a pulp slurry containing activated carbon fibers and mulberry bast fibers is wet-papered to form a web, and then dried.

상기 펄프 슬러리는 물에 활성탄소섬유와 뽕나무 인피섬유를 투입한 후 교반하여 제조된다.The pulp slurry is prepared by adding activated carbon fibers and mulberry bast fibers to water and then stirring.

상기 활성탄소섬유는 비표면적과 흡착력이 우수하여 초미세먼지 및 VOCs 등을 흡착 제거할 수 있다. 상기 활성탄소섬유는 폴리아크릴로니트릴계, 피치계, 페놀계, 레인온계 등의 섬유를 탄화하고 부활시켜 제조한 것으로서, 그 종류는 크게 한정되는 것은 아니다.Since the activated carbon fiber has excellent specific surface area and adsorption power, it is possible to adsorb and remove ultrafine dust and VOCs. The activated carbon fiber is manufactured by carbonizing and activating fibers such as polyacrylonitrile, pitch, phenol, and rainon, and the type is not particularly limited.

상기 활성탄소섬유는 섬유장이 2 내지 4mm인 것이 바람직하다. 섬유장이 2mm 미만인 경우 표면결합력이 저하되어 활성탄소섬유가 탈락될 가능성이 높고, 4mm 초과인 경우 표면결합력은 향상되나 균일하게 분산된 펄프 슬러리를 제조하는데 한계가 있다.The activated carbon fiber preferably has a fiber length of 2 to 4 mm. If the fiber length is less than 2 mm, the surface binding force is lowered and the activated carbon fibers are highly likely to be removed. If the fiber length is more than 4 mm, the surface binding force is improved, but there is a limit to preparing a uniformly dispersed pulp slurry.

그리고, 상기 뽕나무 인피섬유는 표면결합력이 약한 활성탄소섬유에 결합력을 부여하기 위한 것으로서, 섬유장이 7 내지 12mm인 뽕나무 인피섬유를 사용하는 것이 좋다.In addition, the mulberry bast fiber is for imparting binding force to the activated carbon fiber having a weak surface binding force, and it is preferable to use a mulberry bast fiber having a fiber length of 7 to 12 mm.

섬유장이 7mm 미만일 경우 활성탄소섬유와 표면결합력이 좋지 못하여 필터의 물성이 좋지 못하고, 12mm 초과인 경우 꼬임이 발생하고, 표면이 불균일하는 등 품질 균일성이 좋지 못하는 문제가 있다.If the fiber length is less than 7mm, the surface bonding strength with the activated carbon fiber is not good, so the physical properties of the filter are not good.

상기 활성탄소섬유 95 중량%와 상기 뽕나무 인피섬유 5중량%를 혼합하여 펄프슬러리를 제조하는 것이 좋다.It is preferable to prepare a pulp slurry by mixing 95% by weight of the activated carbon fiber and 5% by weight of the mulberry bast fiber.

상기 뽕나무 인피섬유가 적게 혼합될 경우 비표면적이 우수한 필터를 얻을 수 있으나 인장강도 등의 물성이 좋지 못하고, 많이 혼합될 경우 인장강도 등의 물성이 우수한 필터를 었을 수 있으나 활성탄소섬유가 상대적으로 적게 혼합되어 초미세먼지, VOCs 등의 흡착제거성능이 저하되는 문제가 있다.When the mulberry bast fiber is mixed with a small amount, a filter with excellent specific surface area can be obtained, but physical properties such as tensile strength are not good. There is a problem in that the adsorption and removal performance of ultrafine dust and VOCs is reduced due to mixing.

상기 교반은 팔파(pulper) 및 칼비터를 사용하여 교반할 수 있으며, 이때 팔파는 60~100rpm, 칼비터는 10rpm의 속도로 교반하는 것이 좋다.The stirring may be performed using a pulper and a calbiter, and at this time, it is preferable to stir at a speed of 60 to 100rpm for the pulper and 10rpm for the calbiter.

다음으로, 상기 펄프 슬러리를 습식초지법에 의해 웹을 형성한다. 이때 습식초지법으로서 환망초지기 또는 장망초지기를 이용하여 제조할 수 있다.Next, a web is formed on the pulp slurry by a wet papermaking method. In this case, as a wet papermaking method, it can be manufactured using a Hwanmang paper machine or a Jangmang paper machine.

그리고 상기 웹을 건조하기 전에 나노셀룰로오스를 처리한 후 건조하는 것이 좋다. 상기 나노셀룰로오스를 처리함으로서, 인장강도 등의 물성 및 비표면적이 향상된 필터를 제조할 수 있다.And it is preferable to dry the web after treating the nanocellulose before drying the web. By treating the nanocellulose, it is possible to manufacture a filter with improved physical properties such as tensile strength and specific surface area.

상기 나노셀룰로오스의 처리방법은 나노셀룰로오스 용액을 상기 웹 상에 분사키겨 처리하거나, 웹을 나노셀룰로우스 용액 내에 통과시켜 처리할 수 있다.The nanocellulose treatment method may be treated by spraying the nanocellulose solution on the web, or by passing the web through the nanocellulose solution.

특히, 생산성과 비표면적이 양호한 필터를 제조하기 위해, 0.1 wt%농도의 나노셀룰로오스 용액을 상기 웹 상에 분사시켜 처리하는 것이 좋다.In particular, in order to manufacture a filter with good productivity and specific surface area, it is preferable to spray the nanocellulose solution with a concentration of 0.1 wt % on the web for treatment.

이와 같이 제조된 뽕나무 인피섬유를 이용한 필터는 물성이 우수하고, 활성탄소섬유의 접착을 위해 PVA(Polyvinyl Alcohol)을 사용하지 않고 뽕나무 인피섬유를 이용하여 물성이 우수하고 높은 비표면적을 갖는 이점이 있다.The filter using the mulberry bast fiber prepared in this way has excellent physical properties, does not use polyvinyl alcohol (PVA) for adhesion of the activated carbon fiber, and uses mulberry bast fiber to have excellent physical properties and a high specific surface area. .

다음으로, 본 발명의 뽕나무 인피섬유를 이용한 필터의 제조방법을 실시예를 들어 상세히 설명하면 다음과 같고, 본 발명의 권리범위는 하기의 실시예에 한정되는 것은 아니다.Next, the manufacturing method of the filter using the mulberry bast fiber of the present invention will be described in detail with reference to examples, and the scope of the present invention is not limited to the following examples.
