Definitions
- the invention relates to a biodegradable filter according to the preamble of claim 1.
- the invention is therefore based on the object of creating a filter cigarette of the type specified which, while maintaining the advantages of the known filter cigarette, has a "acetate-typical see “taste impression and a” acetate-typical "visual appearance.
- the advantages achieved with the invention are based on the selection of a special cellulose material and the design of a filter cigarette construction that is matched to it, adapting the essential parameters, namely the retention performance of the filter, the strand yield ratio of nicotine / condensate of the tobacco rod, the plug density of the tobacco mixture of the tobacco rod, the Air permeability of the cigarette paper and finally the degree of filter ventilation, in the direction of an overall construction that optimizes the taste impression on the one hand and the visual impression on the other.
- the nicotine yield of the filter cigarette is up to a maximum of 1 mg and the condensate yield of 6 mg to 12 mg.
- the desired degree of ventilation of 15 to 50% can be set by the appropriate design of the ventilation zone in the covering paper and the wrapping.
- the ventilation zone of the filter is formed by one or two rows of holes which are at least 10 mm from the mouth end; the holes can be made either by laser radiation or mechanically on the finished cigarette and should be as small and as little visible as possible, with good results being achieved with 15 to 25 holes in two ventilation rows.
- the filter is made from cellulose material processed according to the so-called "air-laid” process to a random fiber fleece and this is further crimped to the finished filter.
- air-laid a suitable combination of basis weight, thickness and width of the air-laid fleece can be used.
- the processed cellulose fibers are not suspended in water as in the classic paper production process and placed on a permeable sieve for sheet formation, on which the cellulose fibers are then conditioned through their grinding and fibrillation, they are mechanically networked with one another, but rather, at most, are placed in an air stream, which transports them onto a permeable endless sieve and places them on it in an unordered manner.
- a mechanical bond and thus the necessary strength required for further processing is obtained by adding a binder such as polyvinyl alcohol, polyvinyl acetate, polymer starch, dextrin or latex.
- a binder such as polyvinyl alcohol, polyvinyl acetate, polymer starch, dextrin or latex.
- the degree of density (g / cm 3 ) and thus the volume or thickness is set by subsequent calendering.
- the weight per unit area (g / m 2 ) is controlled via the sieving speed or the fiber entry into the air flow.
- the filter cigarette has a tobacco rod surrounded by a cigarette paper and a filter connected to the tobacco rod.
- the topping density of the tobacco mixture is between 200 and 250 mg / ml.
- the tensile resistance of the strand is between 45 and 65 mmWS, measured closed.
- the cigarette paper has a low to medium air permeability in the range of 15 to 50 Coresta units.
- the strand yield ratio nicotine * 10 / condensate of the tobacco mixture should be between 0.6 and 0.9.
- the filter consists of the folded, uncrimped air-laid fleece and is surrounded by a porous wrapping paper.
- a zone-porous covering paper surrounds the wrapping paper and is used to attach the filter to the tobacco rod.
- the air permeability of the porous zone of the covering paper is chosen so that the desired degree of filter ventilation results in connection with the wrapping paper underneath.
