Definitions

  • the invention relates to a cigarette with an increased self-extinguishing tendency, wherein the cigarette paper has annular zones whose porosity is reduced by the presence of a polymer.
  • the object of the invention is on the one hand to satisfy the demands of that test and on the other hand to avoid the disadvantages of the state of the art.
  • the cellulose derivatives applied to the paper, fillers or highly ground fibres form at the surface of the cigarette a film, in the region of which the thickness of the coated paper is markedly increased.
  • the aim is to find a material in which the desired self-extinguishing tendency is not achieved by an external film but by altering the paper structure in the printed region.
  • the actually hydrophobic polymers penetrate into the hydrophilic paper. It is found however that, when the interfacial tension of the polymers used is in the proximity of that of regenerated cellulose, the polymer penetrates into the cavity structure of the paper without a desired film formation occurring at the surface. It is advantageous in that respect if the polar proportion of the interfacial energy is as high as possible. It is therefore essential for the invention that the interfacial tension of the polymer is over 33 mJ/m 2 .
  • polyvinyl acetate Inter alia polyvinyl acetate, partially hydrolysed polyvinyl acetate or polyvinyl alcohol have proven to be particularly suitable.
  • Polyvinyl acetate is polar and its interfacial tension is 36.5 mJ/m 2 .
  • Non-polar ethyl cellulose at 32 mJ/m 2 in contrast is as discussed film-forming and cannot be used in accordance with the invention (all figures from: Polymer Data Handbook, 1999, Oxford University Press Inc).
  • the selected polymer it is necessary for the selected polymer to be applied in a sufficient amount and in a condition of suitable geometrical distribution in order to satisfy the criteria of the NIST test.
  • a width of more than 4 mm is desirable, even if not critical.
  • the bands which stop the cigarette from burning may also not be disposed at excessively great distances, for which reason those distances are preferably below 20 mm.
  • fillers such as aluminium hydroxide, magnesium hydroxide or titanium oxide in the printing solution. Those fillers however have no measurable influence on the self-extinguishing tendency of cigarettes.
  • Examples 6 and 7 confirm the point set out in the opening part of this specification that a reduction in permeability as measured in Coresta Units (CU) still does not guarantee an adequate self-extinguishing tendency. On the contrary the latter is to be measured directly and the application amount is to be increased until the desired result is attained.
