Description

담배필터용 필터원지 및 필터플럭Filter base and filter floe for tobacco filter

본 발명은 각초의 일측에 부착되는 담배용 필터의 필터원지 및 담배필터플럭에 관한 것으로서, 특히 필터원지의 제조시 합성섬유등을 포함하여 끽연시 흡수의 침투를 방지함과 연기성분 제거능력 및 끽미를 향상시키고, 필터의 찌그러짐등을 방지할 수 있도록함을 제공하려는 것이다.The present invention relates to a filter base and a cigarette filter plug of a tobacco filter attached to one side of each herb, in particular, including the synthetic fibers, etc. during the manufacture of the filter paper to prevent the penetration of absorption during smoking, smoke removal ability and taste To improve the performance of the filter and to prevent filter distortion.

일반적으로 초기의 담배용 필터는 연기성분제거의 필요성보다 끽연시 입속으로 빨려들어오는 각초를 막기 위하여 솜(Cotton)등이 사용되었으나, 그후 끽연이 건강에 해롭다는 끽연 위생론이 대두되면서 필터의 재질에 관한 연구가 본격화되었다. 근래에와서는 상기 연구결과 끽미 및 연기성분 제거능력등을 고려하여 담배용 필터 원자재로서는 목재펄프(Wood Pulp)를 무수초산(Acetic Acid Anhydrous)에 용해시켜 필라멘트형태로된 섬유에 의한 셀룰로오스, 아세테이트 필터와 목재펄프(Wood Pulp)를 표백처리하여 이를 초지 크림핑(Crimping) 가공하여 권상한 종이필터로 대별된다.In general, the cigarette filter in the early days was used to prevent the grass that is sucked into the mouth during the smoking rather than the need to remove the smoke component, but since the smoking hygiene theory that smoking is harmful to health has emerged in the material of the filter The research on this is in full swing. In recent years, in consideration of taste and smoke removal ability, as a filter material for tobacco, wood pulp is dissolved in acetic acid anhydrous and cellulose and acetate filters are made of filament-like fibers. And wood pulp are bleached, and the paper is crimped.

상기와 같은 양자의 필터는 연기중의 유해성분을 제거하는데 우수한 효능은 있으나, 전자의 아세테이트필터의 경우에는 원가가 비싸고, 제조공정이 복잡하며 필터 물성에 따라 셀룰로오스, 아세테이트 토우(Cellulose Acetate Tow)의 단사섬유(Mono Denier)와 섬유층섬도(Total Denier)를 변화시키고 그에 따른 토우 특성 분석(Tow Capability Analysis)을 하여야 하는 결점이 있었다. 후자의 종이필터의 경우에는, 제조공정은 간단하나 끽연시 섬유취의 발현으로 끽미가 좋지 않으며 수분의 흡습에 의해 필터의 탄성력이 저하되어 필터가 찌그러드는 현상이 나타나 결국 담배의 빨림이 저하되는 결점이 있는 것이다.Both filters have excellent efficacy in removing harmful components in smoke, but the former acetate filter is expensive, complex manufacturing process, and depending on the filter properties of cellulose, acetate tow (Cellulose Acetate Tow) There was a drawback to change the Mono Denier and Total Denier and perform the Toe Capability Analysis accordingly. In the case of the latter paper filter, the manufacturing process is simple, but the taste is not good due to the appearance of fiber odor during smoking, the elastic force of the filter decreases due to moisture absorption, and the filter collapses, resulting in a decrease in the smoking speed. Is there.

본 발명은 상기한 종래의 제결점을 해결하기 위하여 안출한 것으로서, 그 목적으로는 합성 고분자 섬유와 일반 목재펄프를 혼용한 필터원지를 이용하여 필터의 경도 및 탄력을 높이면서 탈, 나코틴등의 연기 유해성분 제거능력이 우수한 담배필터를 제공함에 있다.The present invention has been made to solve the above-mentioned conventional drawbacks, for the purpose of using a filter paper mixed with synthetic polymer fibers and general wood pulp while increasing the hardness and elasticity of the filter, such as decoating, nacotin To provide a cigarette filter with excellent smoke removal ability.

본 발명의 또다른 목적으로는 담배필터를 권상 시험한 결과 아세테이트 필터보다 원가를 저렴하게 하고, 종이필터에 비해 필터의 탄성도 및 흡습방지 효과를 탁월하게 할수 있도록한 것이 특징이다.In another object of the present invention, the tobacco filter was subjected to the hoisting test, and thus, the cost was lower than that of the acetate filter, and the elasticity and moisture absorption prevention effect of the filter was superior to that of the paper filter.

따라서, 본 발명에서 널리 사용되고 있는 합성 고분자 섬유인 폴리에스터(Polyester) 섬유는 고분자를 이루는 기본결합이 아래와 같은 에스테르 결합으로 되어있다.Therefore, polyester fiber, a synthetic polymer fiber widely used in the present invention, has a basic bond forming a polymer as an ester bond as follows.

상기와 같은 에틸렌과 벤젠환 사이를 에스테르 결합이 연결짓고 있는 구조를 형성하고 있으며, 이벤젠환은 육각형의 평균구조로 되어 서로 잘포개어지는 성질이어서 이것이 규칙적으로 함유된 폴리에스터의 분자쇄는 나란히 배열되기 쉬울뿐아니라 배열된 상태로 중첩하여 결정형태를 잘이루는 특성을 가진다. 따라서, 폴리에스터는 섬유 형성이 아주 우수하고 합성섬유중 가장 중요한 재료이다.The ester bond is formed between the ethylene and benzene rings as described above, and this benzene ring has a hexagonal average structure that is well superimposed with each other so that the molecular chains of the polyesters regularly contained are arranged side by side. Not only is it easy, but it also has the property of forming a crystal by stacking them in an array. Therefore, polyester is excellent in fiber formation and is the most important material among synthetic fibers.
