Definitions

  • the present invention relates to a cigarette paper containing a water-soluble salt, preferably sodium hydrogencarbonate, potassium bicarbonate or ammonium carbonate, whereby a high diffusion capacity during thermal decomposition and thus a reduction of carbon monoxide in cigarette smoke is achieved.
  • a water-soluble salt preferably sodium hydrogencarbonate, potassium bicarbonate or ammonium carbonate
  • Cigarette papers are made from cellulose fibers derived from wood, flax or other materials. Mixtures of cellulose fibers of various origins are also used. Cigarette papers have a typical basis weight of 10 g / m 2 to 60 g / m 2 , with the range of 20 g / m 2 to 35 g / m 2 being generally preferred.
  • Cigarette papers often also contain inorganic, mineral fillers which are added to the paper in a mass fraction of 10% to 40%.
  • a frequently used filler is lime (calcium carbonate).
  • lime calcium carbonate
  • other carbonates and oxides such as magnesium oxide and aluminum hydroxide are also used.
  • the cigarette paper may also be provided with burn salts which increase or decrease the smoldering speed of the paper.
  • burn salts which increase or decrease the smoldering speed of the paper.
  • very often used are trisodium and tripotassium citrate and mixtures thereof, which are added to the paper to 0% to 5% of the paper pulp.
  • the group of fire salts of industrial importance additionally comprises further citrates, malates, tartrates, acetates, nitrates, succinates, fumarates, gluconates, glycates, lactates, oxylates, salicylates, ⁇ -hydroxycaprylates and phosphates.
  • the paper is impregnated, for example, in the size press with a solution or suspension of these Brandsalze, or the solution or suspension is applied in a film press on the surface of the paper.
  • Typical cigarette papers have an air permeability between 10 CU and 300 CU, with the range 20 CU to 120 CU preferably being used. The air permeability can be determined, for example, according to ISO 2965.
  • the diffusion capacity of a cigarette paper for CO 2 can be determined, for example, with the CO 2 Diffusivity Meter from Sodim.
  • Typical cigarette papers have a diffusion capacity between 0.1 cm / s and 3.5 cm / s at room temperature, with the range of 0.5 cm / s to 3.0 cm / s preferably occurring.
  • the diffusion capacity can be measured at room temperature or standard conditions, such as a temperature of 23 ° C and a relative humidity of 50%, after the paper has been conditioned accordingly. Alternatively, among other things, it is also possible to determine the diffusion capacity of the paper after the paper has been subjected to thermal stress, in particular by elevated temperatures.
  • both the air permeability and the diffusion capacity are determined by the pore structure of the cigarette paper, so there is a relationship between these sizes. It proves technically difficult to adjust the diffusion capacity regardless of the air permeability of the paper in the papermaking process.
  • the air permeability is in most cases the subject of the paper specification given by the manufacturers of cigarettes, so that, under this requirement, the diffusion capacity results practically from the papermaking process and only can be varied in a small area. Therefore, there is a particular interest in finding papers whose diffusion capacity increases only when needed, namely, just when the temperature of the paper is increased by the ember on the smoldering cigarette.
  • the substances in cigarette smoke are determined by a method in which the cigarette is smoked according to standardized specifications. Such a method is described for example in ISO 4387.
  • the cigarette is first ignited at the beginning of the first train 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 performed at a sinusoidal tensile profile on the cigarette.
  • the trains are repeated as long as the cigarette until the cigarette falls below a certain predetermined 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 1500 Pa, between the tobacco-facing inside of the cigarette paper 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.
  • this phase which lasts 2 seconds per draw, the extent of dilution is determined by the air permeability of the paper.
  • the cigarette will glow without any appreciable pressure difference between the inside 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. It is also carbon monoxide through the cigarette paper from the tobacco part and in particular from the region of the cone of gluten in the Ambient air diffuse. In this phase, which lasts 58 seconds per turn, the diffusion capacity for the reduction of carbon monoxide is the relevant parameter.
  • the diffusion capacity of the cigarette paper is high and that it is high, in particular in the area of the cone of embers, since at this point the carbon monoxide is formed. It is thus particularly advantageous if the diffusion capacity is high or rises rapidly as soon as the cigarette paper is exposed to elevated temperatures due to the approach of the cone.
  • An object of the invention is to provide a cigarette paper having an increased diffusion capacity, which enables reduction of carbon monoxide in the cigarette smoke.
  • the invention achieves this object by impregnating or coating the cigarette paper with one or more water-soluble salts which, at relatively low temperatures, i. significantly less than 450 ° C, disintegrate and thereby loosen up the pore structure of the paper on a smoldering cigarette made thereof, so that a significantly better diffusion of carbon monoxide from the cigarette is allowed.
  • the water-soluble salt loses more than 20%, preferably more than 25%, more preferably more than 30%, and most preferably more than 35% of its starting material.
  • the water-soluble salt is an inorganic salt or a mixture of inorganic salts.
  • the water-soluble salt is a hydrogencarbonate, preferably an alkali metal bicarbonate or an ammonium bicarbonate, or a carbonate, preferably an ammonium carbonate.
  • a hydrogencarbonate preferably an alkali metal bicarbonate or an ammonium bicarbonate
  • a carbonate preferably an ammonium carbonate.
  • the water-soluble salt or the alkali metal bicarbonate is a sodium or potassium bicarbonate.
  • a mixture of the two salts is also contemplated.
  • the European patent application EP 0 758 532 A2 describes the treatment of a filter pad paper or Tippingpapiers inter alia with an alkali metal bicarbonate, but not the treatment of a "cigarette paper" in the true sense, ie a cigarette paper for wrapping the tobacco rod of a cigarette. The goal of this treatment is to make the filter pad paper easier to dissolve in rainwater so that discarded filters are more likely to degrade in the environment.
  • the alkali metal bicarbonate has the function of neutralizing a carboxymethylcellulose acid (CMS-H) or a carboxyethylcellulose acid (CEC-H), ie to convert it into corresponding alkali metal salts, for example CMC-NA or CEC-Na.
  • CMS-H carboxymethylcellulose acid
  • CEC-H carboxyethylcellulose acid
  • this disclosure does not suggest that cigarette wrapping papers should be treated in a similar manner where the problem of easier disintegration in water does not arise.
  • the alkali metal bicarbonate decomposes at comparatively low temperatures and thus would be suitable for a smoldering cigarette, the pore structure of the paper so mecaniclockern that improved diffusion of carbon monoxide from the cigarette is allowed.

  • cigarette paper as known in the art, is already provided with diffusion-reducing, fire-retardant stripes in order to achieve self-extinguishment of a cigarette produced therefrom in a standardized test (ASTM E2187-04).
  • these fire retardant strips are arranged to form ribbons on the cigarette circumferentially.
  • Such cigarettes have increased levels of carbon monoxide because less carbon monoxide can diffuse from the cigarette through the fire retardant strips.
  • the subregions are separated from fire-retardant areas, preferably fire-retardant strips.

This can be beneficial if the solution is the changed the optical properties of the paper. Then preferably the solution is applied to the later side of the tobacco facing the paper.
  • the subregions are separated from fire-retardant areas.

It has been shown that the increase in the diffusion capacity of the cigarette paper during the thermal decomposition can be partially increased by more than double. Such an increase in the increase in diffusion capacity can significantly contribute to the reduction of harmful carbon monoxide in the smoke of cigarettes made from these papers.
  • Example 1 Preparation of cigarette paper with sodium bicarbonate, potassium bicarbonate or ammonium carbonate
  • This is a common cigarette paper, so that comparable results can be expected with other cigarette papers and in principle there are no restrictions on the selection of the cigarette paper, for example in terms of air permeability, diffusion capacity, fiber and filler composition or basis weight.
