Definitions
- the invention relates to a biodegradable filter according to Preamble of claim 1.
- EP-A-0 745 336 discloses a filter cigarette with a biodegradable filter, the material of which can be produced by the air-laid method.
- the filter is made from cellulose esters, eg cellulose acetate, and the material is crimped.
- EP-A-0 255 114 discloses a filter cigarette whose two-part filter consists of cellulose acetate. With this double filter, the tobacco rod-side filter part has a high retention rate of 60-80% because the filaments of the material are possible fine and lie close together. The document does not say how the material is made.
- the invention is therefore based on the object of a filter cigarette to create the specified type while maintaining the advantages of the known filter cigarette an "acetate typical” Taste impression and a “acetate typical” optical Appearance delivers.
- the advantages achieved with the invention are based on the selection a special cellulose material and the interpretation of a matched filter cigarette construction under adaptation of the essential parameters, namely the retention performance of the Filter, the nicotine / condensate strand yield ratio Tobacco rod, the density of the tobacco mixture of the tobacco rod, the air permeability of the cigarette paper and finally the degree of filter ventilation, towards one Overall construction, on the one hand the taste impression and on the other hand, the optical appearance is optimized.
- the desired degree of ventilation of 15 to 50% can be achieved the corresponding design of the ventilation zone in the covering paper and adjust the wrapping.
- the ventilation zone the filter is formed by one or two rows of holes that is at least 10 mm from the mouth end; the holes can either by laser radiation or mechanically at the finished cigarette and should be made if possible be small and little visible, with good results at 15 to 25 holes can be reached in two ventilation rows.
- 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 caused by them Grinding and fibrillation, mechanically networked with each other, but placed in a single air flow at most, which transports them onto a permeable endless sieve and places them on this 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 input into the air flow.
- the filter cigarette has one surrounded by a cigarette paper Tobacco rod and one connected to the tobacco rod Filter on.
- the density of the tobacco mixture is between 200 and 250 mg / ml.
- the tensile resistance of the strand is between 6 and 8.77 kPa (45 and 65 mmWS), measured closed.
- the cigarette paper has a low to medium air permeability in the range from 15 to 50 cm 3 / min / cm 2 / kPa (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 chosen to be in connection with the wrapping paper underneath the desired degree of filter ventilation results.
