본 발명은 심지형 담배 필터에 관한 것으로, 더욱 상세하게는 필터 소재와 동일한 아세테이트로 제조되는 심지사를 구성함에 있어 합연사 혹은 브레이드(braid)사 형태로 필터 중심부에 삽입하므로써 심지사와 필터의 접합성을 증가시키고 니코틴 및 타르의 여과효율을 향상시킨 심지형 담배 필터에 관한 것이다.The present invention relates to a wick tobacco filter, and more particularly, in the construction of a wick yarn made of the same acetate as the filter material, the bond between the wick and the filter is increased by inserting it in the center of the filter in the form of a jointed yarn or a braid yarn. The present invention relates to a wick tobacco filter having improved filtration efficiency of nicotine and tar.
일반적으로 담배 필터에 있어서 필터의 궐련지 부근의 공기의 순환 작용으로 인하여 담배 연기의 농도가 낮아지 이로 인하여 흡입 압력의 저하가 발생하고 따라서 담배 연기는 주로 중심부에서 여과가 이루어지게 된다.In general, in the cigarette filter, the concentration of the cigarette smoke is lowered due to the circulation action of the air in the vicinity of the cigarette paper of the filter, thereby lowering the suction pressure, and thus the cigarette smoke is mainly filtered in the center.
즉, 권련지 부위의 여과는 담배연기를 공기로 순화시키는 작용으로 이루어지며 필터부재(1)의 중심부에서 실질적인 여과 성능을 나타내게 된다.In other words, the filtration of the cistern area is made by purifying tobacco smoke with air and exhibits substantial filtration performance at the center of the filter member 1.
담배 필터의 여과가 일어나는 중심부는 전체 면적비 대비 약53%정도의 면적을 차지하며 나머지 47%인 궐련지 주위의 아세테이트 토우는 실질적인 여과 작용보다는 모양을 유지하는 역할이 더욱 크다고 할 수 있다.The central part of the filtration of the tobacco filter occupies about 53% of the total area ratio, and the acetate tow around the remaining 47% of the cigarette paper retains its shape rather than the actual filtration.
이러한 비효율성을 개선하기 위한 방안으로 아세테이트 토우 필터부재 (1)의 중심부에 심지사를 삽입하여 중심부로 흐르는 담배 연기를 궐련지 주위의 상기 필터부재(1)로 분산시켜 수환 효과 증대와 더불어서 여과 유효면적을 증대시키는 방법이 대두되었다.In order to improve such inefficiency, a wick is inserted into the center of the acetate tow filter member 1 to disperse the tobacco smoke flowing to the center to the filter member 1 around the cigarette paper, thereby increasing the water-receiving effect and filtration effective area. A way to increase
하지만 종래에는 심지사로서 폴리에틸렌이나 폴리프로필렌과 같이 필터와 다른 소재를 사용하였기 때문에 심지사에서는 담배 연기의 여과작용은 전혀 이루어지지 않고, 또한 다른 소재의 사용으로 인하여 담배 필터에 사용된 아세테이트 토우와의 접합성을 해결해야 하는 문제점을 갖고 있다. 즉, 아세테이트 토우 필터부재(1)와 심지사의 접합면에서 필터 제조시 가소제첨가 후에도 밀착이 용이하지 않게되어 흡입 압력이 적정 수준을 유지하지 못하는 문제점이 있다.However, in the past, since the wick used a different material from the filter, such as polyethylene or polypropylene, the wick does not filter the smoke at all, and due to the use of other materials, the bondability with the acetate tow used in the cigarette filter is reduced. I have a problem that needs to be solved. That is, there is a problem in that the suction pressure is not maintained at an appropriate level because the adhesion is not easy even after the plasticizer is added during the manufacture of the filter at the joint surface of the acetate tow filter member 1 and the wick.
따라서 본 발명은 이러한 종래 기술의 문제점을 해결한 것으로, 기존의 로드 형태 대신 필터 소재와 동일한 아세테이트 토우를 합연사 혹은 브레이드사 형태로 구성시켜 심지사로 사용되도록 하므로써 필터 제조시 가소제 첨가 후의 문제점이 발생하지 않고 아세테이트 토우 필터부재(1)와 심지사의 접합성도 증가시키면, 심지사 표면과 심지사 형태에 따라 내부에도 일정한 여과성능을 부여하여 여과효율을 향상시킨 심지형 담배 필터를 제공하는데 그 목적이 있다.Therefore, the present invention solves the problems of the prior art, so that the same acetate tow as the filter material instead of the conventional rod form in the form of a twisted yarn or braid yarn to be used as a wick, so that the problem does not occur after the plasticizer is added in the manufacture of the filter. Without increasing the adhesiveness of the acetate tow filter member 1 and the wick, the purpose is to provide a wick tobacco filter that improves the filtration efficiency by providing a constant filtration performance in accordance with the wick surface and the wick shape.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명에서는 사용한 아세테이트 토우 합연사는 아세테이트 토우 9,000∼12,000데니어를 사용하여 합연 후 총 데니어가 32,000∼40,000이 되도록 제조하며, 합연사 제조시 꼬임계수(이하 T/M)는 30∼120으로 조절한다. 또한, 브레이드사는 15,000∼20,000데니어로 제조한다.In the present invention, the used acetate tow twisted yarn is manufactured so as to have a total denier of 32,000 to 40,000 after joining using acetate tow 9,000 to 12,000 denier, and the twisting factor (hereinafter referred to as T / M) is adjusted to 30 to 120 when manufacturing the twisted yarn. In addition, braid yarn is manufactured from 15,000 to 20,000 denier.
합연사와 브레이드사의 지름은 필터 제조시의 공정성을 고려하여 1∼4mm범위로 조절하고 또한 심지사 첨가 필터를 단일 필터로 하거나 혹은 심지사 필터분을 4∼18mm로 조절한 이중 필터로 사용한다.The diameter of plywood and braided yarns is adjusted in the range of 1 to 4 mm in consideration of the fairness in the manufacture of the filter, and used as a single filter or a dual filter in which the core yarn filter is adjusted to 4 to 18 mm.
이하, 본 발명을 실시예 및 비교예를 통하여 더욱 구체적으로 설명하겠는바, 본 발명이 실시예에 의하여 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited to the Examples.
