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 lit at the beginning of the first turn and then every minute a pull at the mouth end of the cigarette with a duration of 2 seconds and a volume of 35 cm 3 was carried out on a sinusoidal draft profile 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 of the cigarette paper 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 of the cigarette paper has an independent, important importance for the carbon monoxide content in the cigarette smoke and that the values of carbon monoxide in the cigarette smoke can 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 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 particle size distribution characterizes the granulometric state of a particle collective and describes the probability distribution of the particle size in the particle collective.
  • the particle size is determined by the diffraction pattern of a laser beam.
  • different models are used, for example according to Fraunhofer or Mie.
  • the Mie model with material parameters for calcite is used. From the particle size distribution measured in this way it is possible, for example, to deduce which volume fraction of the particles is smaller than a predetermined size.
  • Such proportions may be given, for example, in the form "d x " where x is a number between 0 and 100 and d is a measure of particle size.
  • d 10 0.5 ⁇ m means that 10 % by volume of the particles in the collective are smaller than 0.5 ⁇ m.
  • the particle size "d" corresponds to the diameter of a spherical particle.
  • the particle size "d” corresponds to the diameter possessed by a spherical particle, which, measured according to ISO 13320, gives the same result as the particle without spherical shape.
  • the particles which are distributed according to the above-mentioned particle size distribution, for the most part be platelet-shaped or non-platelet-shaped and in particular consist of lime.
  • a non-platelet-shaped particle is considered in which the length l and the width b are less than four times as large, preferably less than twice the thickness d, the length l, the width b and the thickness d each corresponding to the maximum dimensions in three mutually orthogonal directions in space.
  • the length 1, the width b and the thickness d could correspond, for example, to the edge lengths of the cuboid, i. H.
  • the length 1 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 differ by a factor of 2.5 or less from the longest spatial direction of the particle.
  • the diffusion capacity of the cigarette paper can be influenced particularly favorably.
  • a comparatively high diffusion capacity can be achieved for a given air permeability.
  • the inventors have found that when this distribution parameter p is about 5 ⁇ m in size falls short of an unexpected and sharp increase in the diffusion capacity of the cigarette paper. Further, the inventors have found that if the distribution parameter falls below a value of about 4 ⁇ m, a plateau is formed and no similar increase in the diffusion capacity can be expected, but the diffusion capacity remains at a high level. This connection is in Fig. 3 shown.
  • the distribution parameter p may also assume values less than 0 ⁇ m, and in general, one will choose the particle size distribution such that p is greater than -1 ⁇ m.
  • the particle size distribution of the total filler in the paper is chosen such that the distribution parameter p assumes a value as defined above.
  • the proportion of the filler with a particle size distribution according to the invention is sufficiently high to provide the described technical effect.
  • the proportion of the filler with the particle size distribution according to the invention in the total filler content as mentioned above should be at least 50% by weight, preferably at least 70% by weight and in particular at least 90% by weight.
  • the filler is preferably precipitated lime.
  • the filler is preferably precipitated lime.
  • other fillers for example, magnesium oxide, magnesium hydroxide, aluminum hydroxide, titanium dioxide, iron oxide, or combinations thereof.
  • 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 applies to the diffusion capacity 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 ⁇ 1.90 cm / s and in particular ⁇ 2.0 cm / s.
  • the total particle size distribution is significantly more critical than the mean particle size alone, ie the desired effect is achieved essentially independently of the mean particle size.
  • the median value d 50 of the particle size distribution measured according to ISO 13320 with Mie correction for calcite is between 0.2 ⁇ m and 4.0 ⁇ m, preferably between 0.5 ⁇ m and 3.0 ⁇ m.
  • 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 .-%.
  • Cigarette paper preferably has a basis weight of 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 the increased fire protection should not increase the health hazard 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.
  • the particle size distribution of each type of lime was determined by means of laser diffraction according to ISO 13320.
  • the measurement of all types of lime was carried out with a device from CILAS named CILAS 1064 (serial number 273) and the evaluation with the software "The Particle Expert" v 6.15.
  • the Mie model for calcite was used.
  • the measurement was carried out by means of a wet dispersion, in which the sample was dispersed in a liquid by means of the ultrasonic dispenser integrated in the measuring device. This ultrasonic dispenser was operated at a power of 50 watts and a frequency of 38 kHz.
  • the liquid used was distilled water.
  • the aim of the invention is to influence the diffusion capacity as much as possible and the air permeability as little as possible, if one changes the filler content. Since the paper sheets all have a different air permeability, it is necessary to normalize the values on the paper with a uniform air permeability - here 50 CU - in the manner described above.
  • the distribution parameter p of the particle size distribution of the filler is not more than 5.0 ⁇ m, preferably not more than 4.0 ⁇ m and particularly preferably not more than 3.5 ⁇ m, but at least -1, 0 microns, preferably at least 0.0 microns and more preferably at least 1.0 microns.
  • Papers Nos. 10 and 12-18 thus belong to the embodiments according to the invention, while the other papers show that fillers with particle size distributions whose distribution parameter p is outside the value range according to the invention do not achieve the desired effect.
  • ⁇ ⁇ D 50 * one obtains, as the inventors could show, for fillers with a particle size distribution whose distribution parameter p is between 5.0 ⁇ m and -1.0 ⁇ m, preferred upper limits for the distribution parameter p being 4.0 ⁇ m, preferably 3.5 ⁇ m are, and preferred lower limits at 0.0 microns, preferably at 1.0 microns.
