Definitions

  • the present invention relates to a cigarette paper containing pulp fibers and filler particles.
  • the term "contain” does not exclude that the cigarette paper contains other ingredients.
  • it relates to a cigarette paper which makes it possible to reduce the amount of carbon monoxide in cigarette smoke and an associated cigarette.
  • the substances in the cigarette smoke are determined by a method in which the cigarettes are smoked to standardized specifications. Such a method is described for example in ISO 4387.
  • the cigarette is first at the beginning of the The first train was lit and then every minute, a train at the mouth end of the cigarette with a duration of 2 seconds and a volume of 35 cm 3 with a sinusoidal Glasprofil performed on the cigarette. The moves are repeated until the cigarette falls below a certain, given in the standard length.
  • the smoke flowing from the mouth end of the cigarette during traction is collected in a Cambridge Filter Pad and this filter is thereafter chemically analyzed for its content of various substances, such as nicotine.
  • the gas phase flowing from the mouth end of the cigarette through the Cambridge Filter Pad during trains is collected and also chemically analyzed, for example to determine the level of carbon monoxide in the cigarette smoke.
  • the cigarette is therefore in two fluidically different states.
  • there is a significant pressure difference typically in the range of 200 Pa to 1000 Pa, between the tobacco facing inside and the outside of the cigarette paper.
  • air flows through the cigarette paper in the tobacco part of the cigarette and dilutes the resulting smoke during the move.
  • the extent of dilution of the cigarette smoke is determined by the air permeability of the paper.
  • the air permeability is determined according to ISO 2965 and indicates which air volume per unit time, per unit area and per pressure difference flows through the cigarette paper and therefore has the unit cm 3 / (min cm 2 kPa).
  • CU CORESTA unit
  • the air permeability of cigarette papers is in the range of 0 CU to 200 CU, with the range of 20 CU to 120 CU being generally preferred.
  • the cigarette will glow without any appreciable pressure difference between the interior of the tobacco part of the cigarette and the environment, so that the gas transport is determined by the gas concentration difference between the tobacco part and the environment.
  • carbon monoxide can also diffuse through the cigarette paper from the tobacco part into the ambient air.
  • the diffusion capacity is the relevant parameter for the reduction of carbon monoxide.
  • the diffusion capacity of a cigarette paper for CO 2 can be determined, for example, with the CO 2 Diffusivity Meter from Sodim and is closely related to the diffusion capacity of a cigarette paper for CO.
  • the diffusion capacity should have an independent, important importance for the carbon monoxide content in the cigarette smoke and that the values of carbon monoxide in the cigarette smoke should be reduced by increasing the diffusion capacity.
  • This is particularly important in view of the self-extinguishing cigarettes known from the prior art, in which comparatively high levels of carbon monoxide are observed.
  • fire retardant streaks are applied to the cigarette paper for self extinguishment in a standardized test (ISO 12863). This or a similar test, for example, is part of legal regulations in the US, Canada, Australia and the European Union.
  • the increased levels of carbon monoxide are due to the fact that the carbon monoxide can diffuse from the cigarette only to a very small extent by the fire-retardant strip. It would therefore be of great advantage to have cigarette papers available that compensate for this undesirable side effect.
  • the US 5,253,660 discloses a cigarette paper in which a novel filler is used which reacts strongly endothermically upon combustion to produce non-combustible, non-toxic and non-corrosive gases.
  • the filler consists of a mixture of huntite (Mg 3 Ca (CO 3 ) 4 ) and hydromagnesite (Mg 4 (CO 3 ) 3 (OH) 2 .3H 2 O).
  • the filler with this chemical composition can occur in five different variants, one of which is described as "platelet-shaped".
  • the present invention has for its object to provide a cigarette paper, which allows a selective reduction of the carbon monoxide content in cigarette smoke at a given air permeability.
  • the cigarette paper contains pulp fibers and filler particles, wherein at least a part of the filler particles has a platelet-shaped form.
  • the inventors have found that the diffusion capacity of the cigarette paper - while maintaining the air permeability - can be substantially increased if at least a portion of the filler particles has a platelet-like shape. Particularly high diffusion capacities can be achieved if the entire filler is formed from platelet-shaped particles. Nevertheless, one can occasionally use a smaller proportion of platelet-shaped filler for cost reasons.
  • at least 20%, preferably at least 40%, particularly preferably at least 55% and in particular at least 70% of the filler particles, based on the mass or on the particle number have a platelet-like shape.
  • Such different proportions of platelet-shaped and non-platelet-shaped particles can be achieved, for example, by adding different filler types in mixture to the paper.
  • the platelet-shaped filler particles have a length 1, a width b and a thickness d, which correspond to the respective maximum dimensions in three mutually orthogonal spatial directions, both the length 1 and the width b at least twice as large, preferably at least four times are as big as the thickness d.
  • the length 1 and the width b will usually be different from each other, but should differ by a factor of less than 5, preferably less than 3 and more preferably less than 2.
  • the length 1, the width b and the thickness d could correspond, for example, to the edge lengths of the cuboid, i. H. it is by no means necessary for the length 1 to correspond to the longest dimension of the particle, which in the case of an idealized cuboid would correspond to the spatial diagonal. In general, however, the length 1 will be greater than or equal to the width b, and in turn will differ by a factor of 2.5 or less from the longest spatial direction of the particle.
  • FIG. 1 illustrates a platelet-shaped filler particle in which the length 1, width b and thickness d are drawn.
  • the diffusion capacity D * in conventional papers is, to a good approximation, proportional to the root of the air permeability Z in CU, that is, D * ⁇ Z (1/2) .
  • D x * for CO 2 of a cigarette paper with an air permeability of x CU therefore: D x * ⁇ 50 / x ⁇ 1 . 80 cm / s . preferably ⁇ 1.85 cm / s.
  • the geometry that is to say the platelet shape, is significantly more decisive than the mean particle size, ie the desired effect is achieved within certain limits independently of the average particle size.
  • the mass-median value d 50 of the particle size distribution measured according to ISO 13317-3 is between 0.2 ⁇ m and 4.0 ⁇ m, preferably between 0.5 ⁇ m and 3.0 ⁇ m.
  • the filler material is initially not further limited as long as the filler is permitted for cigarette paper for toxicological or legal reasons.
  • the filler contains platelet-shaped calcium carbonate, which is completely safe in terms of health and legal considerations.
  • platelet-shaped calcium carbonate it is not necessary for the filler to be completely formed by platelet-shaped calcium carbonate, but calcium carbonates without platelet-shaped geometry or completely different fillers may also be added.
  • the calcium carbonate is a calcite, a vaterite, or a mixture thereof, which are preferred over aragonite or other modifications of the calcium carbonate.
  • the mixture consists of 50 wt% to 70 wt% calcite and 30 wt% to 50 wt% vaterite.
  • the filler according to the invention can be added to the paper in the usual way, as is known to the person skilled in the art in papermaking. Also, in the production of the paper requires no additional, special measures after the addition of the filler according to the invention.
  • the total filler content of the paper between 10 wt .-% and 45 wt .-%, particularly preferably between 20 wt .-% and 40 wt .-%.
  • the cigarette paper preferably has a basis weight of from 10 g / m 2 to 60 g / m 2 , particularly preferably from 20 g / m 2 to 35 g / m 2 .
  • the paper is treated in areas with fire retardant materials that are capable of imparting self extinguishing properties to a cigarette made from the paper.
  • fire retardant areas hinder the diffusion of CO out of the cigarette between two consecutive trains. This is the reason why such self-extinguishing cigarettes are typically observed to have elevated CO levels. This is a significant problem because increased fire safety should not be at the expense of the harmfulness of cigarette smoke.
  • the typical increase in the CO content in cigarette smoke due to the fire-retardant regions can be at least partially compensated by the increased diffusion capacity of the paper in the untreated sections. Therefore, the invention in connection with such treated paper unfolds a special technical effect.
  • Example 1 a non-inventive cigarette paper consisting of wood pulp fibers and 25.5 wt .-% of a conventional, non-platelet, precipitated calcium carbonate, which served as a comparative example.
  • the cigarette paper had a basis weight of 28.2 g / m 2 and an air permeability of 46.9 CU.
  • Another identical cigarette paper was prepared, but in which instead of the conventional calcium carbonate, a calcium carbonate with platelet-shaped particles was used. X-ray diffraction analysis revealed that this is a mixture of about 60% by weight of calcite and about 40 % by weight of vaterite. The average particle diameter was about 1.1 ⁇ m. A method for producing such platelet-shaped calcium carbonate is in EP 1 151 966 B1 described.
  • a non-inventive cigarette paper consisting of pulp fibers from 30.2 wt .-% of a conventional non-platelet precipitated calcium carbonate was prepared as a comparative example.
  • This cigarette paper was modified by using again a mixture of calcite and vaterite having a platelet-like structure instead of the conventional calcium carbonate.
  • the modified cigarette paper had a filler content of 31.0% by weight, a basis weight of 29.1 g / m 2 and an air permeability of 59.5 CU.
  • the diffusion capacity was 2.17 cm / s.
  • Such a high diffusion capacity, as achieved by the paper according to the invention according to Example 2 would be expected in conventional cigarette papers only at an air permeability of about 85 CU.
  • the cigarette papers according to the invention allow a considerably improved diffusion of carbon monoxide from the tobacco rod of a cigarette made with this paper, without having to change the air permeability of the cigarette paper.
