본 발명은 입자상 활성탄을 함유하는 시트상 탈취필터 및 그의 제조방법에 관한 것으로서, 보다 구체적으로는 입자상 활성탄(Activated Carbon : 이하"AC"라고 한다)들이 균일하게 분산된 상태에서 열융착 섬유에 의해 부분적으로 열융착되어 시트(Sheet)를 형성하는 탈취필터 및 이를 간단한 공정으로 제조하는 제조방법에 관한 것이다.The present invention relates to a sheet-like deodorizing filter containing particulate activated carbon and a method of manufacturing the same, and more particularly, in the state in which particulate activated carbon (hereinafter referred to as "AC") is uniformly dispersed by heat-sealed fibers. It relates to a deodorizing filter that is heat-sealed to form a sheet (Sheet) and a manufacturing method for manufacturing the same in a simple process.

활성탄(AC)을 사용하여 탈취필터를 제조하는 종래방법으로는 분말상의 활성탄(AC)을 액상의 바인더에 분산시킨 후 이를 망상의 스폰지나 부직포에 함침시켜 탈취필터를 제조하는 방법이 사용되어 왔다. 그러나, 상기 종래방법은 제조공정 중 분말상의 활성탄(AC)이 비산되는 문제와 액상의 바인더로 인해 기공의 일부가 막혀 탈취성능이 감소하는 문제가 있었다.As a conventional method of manufacturing a deodorizing filter using activated carbon (AC), a method of preparing a deodorizing filter by dispersing powdered activated carbon (AC) in a liquid binder and impregnating it in a mesh sponge or nonwoven fabric has been used. However, the conventional method has a problem in that powdered activated carbon (AC) is scattered during the manufacturing process and a part of the pores due to the liquid binder is blocked, the deodorizing performance is reduced.

이와 같은 종래의 문제점을 극복하기 위한 또 다른 종래방법으로는 입자상의 활성탄(AC)과 열융착 파우더(Powder)를 건식 방식으로 혼합하여 시트(Sheet)상으로 성형하고, 그의 양면에 얇은 커버용 부직포를 부착시켜 탈취필터를 제조하는 방법도 일부 사용되어 왔다.Another conventional method for overcoming such a conventional problem is to form a sheet (Sheet) by mixing the granular activated carbon (AC) and thermal fusion powder (Powder) in a dry manner, a thin cover non-woven fabric on both sides The method of preparing a deodorizing filter by attaching a has also been used.

상기 종래방법은 활성탄(AC)이 공정 중에 비산되는 문제는 방지할 수 있지만, 입자상의 활성탄(AC)과 열융착 파우더가 열접착되는 면적이 좁아 접착력이 낮기 때문에 탈취필터의 성형공정이나 사용 중에 입자상의 활성탄(AC)이 탈취필터로 부터 쉽게 탈락되는 문제가 있었다.The conventional method can prevent the problem of scattering of activated carbon (AC) during the process, but since the area where the activated carbon (AC) and the heat-sealed powder is thermally bonded is small, the adhesive strength is low, so that the particulate matter during the molding process or use of the deodorizing filter is low. There was a problem that the activated carbon (AC) is easily eliminated from the deodorizing filter.

이와 같은 문제를 해결하기 위해서 열융착 파우더 대신에 접착면적이 상대적으로 넓은 열융착 섬유를 입자상의 활성탄(AC)과 건식방식으로 혼합하여 시트상으로 성형하는 방법도 시도되었지만, 상기 방법은 입자상의 활성탄과 열융착 섬유를 균일하게 혼합하는 것이 매우 어렵고, 시트 형성을 위해서는 열융착 섬유의 사용량을 일정수준 이상으로 높게 유지해야 하는 문제점 등이 발생되어 실시가 불가능하였다.In order to solve such a problem, a method of forming a sheet by mixing the thermally fused fiber having a relatively large adhesive area with dry granular activated carbon (AC) instead of the thermally fused powder has also been attempted. It is very difficult to uniformly mix the heat-sealed fibers, and in order to form the sheet, the use of the heat-sealed fibers has to be maintained at a predetermined level or higher.

또 다른 종래방법으로는 벌집(Honeycomb) 모양의 격자사이에 입자상의 활성탄(AC)을 충진시킨 후 입자상 활성탄(AC)의 탈락을 방지하도록 벌집의 양옆을 메쉬로 덮어 탈취필터를 제조하는 방법도 실시되어 왔다. 그러나, 상기 종래방법은 제조공정이 복잡하고, 입자 직경이 작은 활성탄(AC)의 사용이 불가능한 문제 등이 있었다.In another conventional method, a method of manufacturing a deodorizing filter by filling granular activated carbon (AC) between honeycomb-shaped lattices and then covering both sides of the honeycomb with a mesh to prevent falling of particulate activated carbon (AC) is performed. Has been. However, the conventional method has a problem in that the manufacturing process is complicated and the use of activated carbon (AC) having a small particle diameter is impossible.

본 발명은 제조공정 중 활성탄이 비산되는 문제와 입자상 활성탄(AC)이 탈취필터로부터 쉽게 탈락하는 종래의 문제점들을 해소할 수 있도록 입자상 활성탄(AC)들이 고르게 분산된 상태에서 열융착 섬유에 의해 부분적으로 열접착되어 시트(Sheet)를 형성하고 있는 탈취필터를 제공하고자 한다.The present invention is partly made by heat-sealing fibers in a state where the granular activated carbons (AC) are evenly dispersed in order to solve the problem of scattering activated carbon during the manufacturing process and the conventional problems that the particulate activated carbon (AC) easily falls off from the deodorizing filter. An object of the present invention is to provide a deodorizing filter that is heat bonded to form a sheet.

또한, 본 발명은 습식공정에 의해 입자상 활성탄(AC)과 열융착 섬유가 고르게 분산 및 열접착된 탈취시트 및 이를 포함하는 탈취필터를 제조하는 방법을 제공 하고자 한다.In addition, the present invention is to provide a deodorizing sheet in which the particulate activated carbon (AC) and the heat-sealed fibers are evenly dispersed and thermally bonded by a wet process, and a method for manufacturing a deodorizing filter including the same.
