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 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). However, 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. 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 C0 2 can be determined, for example, with the CO2 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 ped and this filter is thereafter chemically analyzed for its content of various substances, for example nicotine.
  • the gas phase flowing from the mouth end of the cigarette during the trains through the Cambridge Filter Päd is collected and also chemically analyzed, for example to determine the content 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.
  • 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.
