Description

분해성 권련 필터{DEGRADABLE CIGARETTE FILTERS}Degradable Cigarette Filters {DEGRADABLE CIGARETTE FILTERS}

본 발명은 분해성 권련 필터, 더 구체적으로는 분해성 물질로 만들어진 모양 지어진 섬유 및 권련 필터에서 그러한 모양 지어진 섬유의 이용에 관한 것이다. The present invention relates to degradable filter filters, more particularly shaped fibers made of degradable materials and the use of such shaped fibers in a filter filter.

종래의 권련 필터 플러그는 트리아세틴에 의해 서로 결합된 셀룰로오스 아세테이트 섬유로 만들어져 있었다. 흡연 후, 사용된 필터는 환경으로 버려지는 경우가 있다. 그것 안의 셀룰로오스 아세테이트 필라멘트는 담배 및/또는 권련의 종이 부분 보다 느리게 분해되어 종종 환경에 쓰레기가 되어 왔다. 이런 쓰레기를 줄이기 위해서는 권련 필터의 셀룰로오스 아세테이트를 환경에서 셀룰로오스 아세테이트 보다 빨리 분해되는 물질로 대체할 필요가 있다. 동시에, 셀룰로오스 아세테이트 트리아세틴계 유래의 여과 화학, 흡연 특성들 및 소비자 용인성 또한 유지되어야 할 필요가 있다.Conventional crimp filter plugs were made of cellulose acetate fibers bonded together by triacetin. After smoking, the filter used may be thrown away into the environment. Cellulose acetate filaments therein degraded more slowly than paper and tobacco parts of cigarettes and / or cigarettes and have often become waste to the environment. To reduce this waste, it is necessary to replace the cellulose acetate of the cistern filter with a substance that degrades faster than cellulose acetate in the environment. At the same time, the filtration chemistry, smoking properties and consumer acceptability derived from cellulose acetate triacetin-based also need to be maintained.

본 발명의 목적은 디자인된 절단면을 갖는 섬유로 형성되는 생분해성 물질로부터 제조된 권련 필터이다. It is an object of the present invention to provide a cigarette filter made from a biodegradable material which is formed from a fiber having a designed cut surface.

본 발명의 다른 목적은 필터당 전체적인 물질의 양은 감소하되 증가된 표면적을 갖는 생분해성의 모양 지어진 섬유의 권련 필터이다.Another object of the present invention is a crimped filter of biodegradable shaped fibers having an increased surface area while reducing the total amount of material per filter.

본 발명의 또 다른 목적은 향기의 전달 및 선택적 여과를 위해 안에 방향제나 흡착제를 보유하기 위해 미세 공극을 가진 생분해성의 모양 지어진 권련 필터이다.Yet another object of the present invention is a biodegradable shaped cistern filter with micropores for retaining fragrances or adsorbents in for delivery and selective filtration of fragrances.

본 발명에 따라서, 생분해성 권련 필터는 피에이치비브이(PHBV)의 모양 지어진 섬유를 포함한다. 섬유는 절단면이 Y, V, C, 트라이어드(Triad), 4-디지(4-DG), 제이씨(JC) 모양을 갖도록 디자인될 수 있다. 또한, 모양 지어진 섬유는 공극 안의 흡착제 및/또는 방향제를 가진 미세 공극을 포함할 수 있다.In accordance with the present invention, the biodegradable citrus filter comprises a shaped fiber of PHBV. The fibers can be designed such that the cut surface has a Y, V, C, Triad, 4-DiG, 4-JC shape. The shaped fibers may also include micropores with adsorbents and / or fragrances in the pores.

본 발명의 새로운 특징과 장점은 첨부되는 도면(유사한 부분은 유사한 참조 글자로 표시되어 있다)과 하기의 상세한 설명을 통해 당업자에게 쉽게 이해될 것이다. The novel features and advantages of the present invention will be readily understood by those skilled in the art through the accompanying drawings (where like parts are indicated by like reference characters) and the following detailed description.

도 1은 Y 모양을 갖는 모양 지어진 생분해성 섬유의 절단면도이다.1 is a cutaway view of a shaped biodegradable fiber having a Y shape.

도 2는 V 모양을 갖는 모양 지어진 생분해성 섬유의 절단면도이다.2 is a cut away view of a shaped biodegradable fiber having a V shape.

도 3은 C 모양을 갖는 모양 지어진 생분해성 섬유의 절단면도이다.3 is a cut away view of a shaped biodegradable fiber having a C shape.

도 4는 트라이어드(triad)의 모양을 갖는 모양 지어진 생분해성 섬유의 절단면도이다.4 is a cutaway view of shaped biodegradable fibers having the shape of a triad.

도 5는 4-디지(4-DG) 모양을 갖는 모양 지어진 생분해성 섬유의 절단면도이다.5 is a cutaway view of shaped biodegradable fiber having a 4-digit (4-DG) shape.

도 6은 제이씨(JC) 모양을 갖는 모양 지어진 생분해성 섬유의 절단면도이다.6 is a cross-sectional view of shaped biodegradable fiber having a JC shape.

본 발명의 권련 필터는 종이, 양모, 낮은 아세틸화 수준을 가진 셀룰로오스 아세테이트, 전분 및 전분 기초 폴리머 복합체, 면, 폴리아크틱 에시드 , 폴리비닐 알코올, 폴리히록시알카노에이트, 폴리에스테르, 폴리에스테르아마이드 , 폴리카프로락톤, 비안정화 폴리프로필렌, 미세 유리 물질, 및 이들의 조합과 같은 생분해성 물질로부터의 박판(sheets), 박막(films), 섬유 밴드(fiber band), 방적사 (yarns), 또는 부직포로 만들어질 수 있다. 생분해성 물질은 용해 방적(melt spinning), 건식 방적(dry spinning), 습식 방적(wet spinning), 전기 방적(elctro spinning) 또는 알려진 다른 방식에 의해 섬유로 자아질(spun) 수 있다. The filter of the present invention comprises paper, wool, cellulose acetate with low levels of acetylation, starch and starch based polymer composites, cotton, polyacetic acid, polyvinyl alcohol, polyhydroxyalkanoate, polyester, polyesteramide, Made from sheets, films, fiber bands, yarns, or nonwovens from biodegradable materials such as polycaprolactone, unstabilized polypropylene, fine glass materials, and combinations thereof Can lose. Biodegradable materials may be spun into fibers by melt spinning, dry spinning, wet spinning, elctro spinning or other known methods.

예를 들면, 피에이치비브이(PHBV; Polyhydroxybutyrate-co-hydroxyvalerate) 및 그와 에코플렉스(Ecoflex) 같은 지방족 방향족 폴리에스테르, 피비에스(PBS; polybutylenes succinate), d-, 1- 및 dl,- 피엘에이(PLA; polyactic acid) 및 전분 복합체와의 그것의 블랜드는 용해 방적 과정에 의해 둥근 절단면의 섬유로 성공적으로 자아졌다(spun).For example, PBV (polyhydroxybutyrate-co-hydroxyvalerate) and aliphatic aromatic polyesters such as Ecoflex, PBS (polybutylenes succinate), d-, 1- and dl, -PLA ( Its blends with PLA (polyactic acid) and starch complexes were successfully spun into round cut fibers by the dissolution spinning process.

섬유의 절단면은 방적 과정에서 사용되는 염료의 형태에 의해 조절될 수 있다. 도 1 내지 6에서 보는 것처럼, 섬유의 절단면은 용해 방적 과정에서 적절한 염료를 사용함에 의해 Y, V, C, 트라이어드(triad), 4-디지(4-DG), 제이씨(JC)로 변형될 수 있다. 미국 특허 6,907,895와 같은 인용 문헌에서 보고된 바 있는 다른 섬유 절단면이 참조로 여기에 포함된다.The cut surface of the fiber can be controlled by the type of dye used in the spinning process. As shown in Figures 1 to 6, the cut surface of the fiber can be transformed into Y, V, C, triad, 4-digit (4-DG), JC (JC) by using a suitable dye in the dissolution spinning process. have. Other fiber cut surfaces as reported in cited documents such as US Pat. No. 6,907,895 are incorporated herein by reference.

이들 모양 지어진 섬유를 권련 필터로 가공하기 위해서는, 단일 또는 다중 성분들로부터의 모양 지어진 섬유의 단일 또는 다중 가닥이 견인 밴드(tow bands)로 빨려져서 권축되거나(crimp), 또는 더 신속히 분해되는 물질로 만들어진 모양 지어진 섬유의 가닥을 권련 필터 제조 과정 중에 조인트 견인 밴드를 형성하도록 셀룰로오스 아세테이트 섬유와 결합되어질 수 있다. 대안으로, 상기 섬유로부터의 멜트 블로운(melt-blown), 스펀 본드(spun bonded), 바늘 천공/펠트(felt), 습식(wet-laid), 에어 레이(air-laid) 및 다른 공정들로부터 부직포는 제작될 수 있고, 그리고 나서 회전, 접기, 절단 공정을 통해 권련 필터로 가공된다. 경도 및 연기 대상 적응을 위한 요구에 따라 적당량의 결합/경화제가 필터에 있는 섬유 위로 적용될 수 있다. 탄소 과립 같은 흡착제나 멘톨 같은 방향제가 또한 모양 지어진 섬유의 미세 공극으로 스며들게 할 수 있다.In order to process these shaped fibers into a scouring filter, single or multiple strands of shaped fibers from single or multiple components are sucked into tow bands and crimped or degraded more quickly. The strands of shaped fibers made can be combined with cellulose acetate fibers to form a joint traction band during the manufacture of a cuff filter. Alternatively, from melt blown, spun bonded, needle punched / felt, wet-laid, air-laid and other processes from the fiber The nonwoven can be fabricated and then processed into a citrus filter through rotation, folding and cutting processes. Appropriate amounts of bonding / hardening agents may be applied over the fibers in the filter, depending on the hardness and the need for adaptation to the smoke target. Adsorbents such as carbon granules or fragrances such as menthol can also penetrate into the fine pores of the shaped fibers.
