Definitions
- the invention relates to a cigarette according to the preamble of claim 1.
- the object of the invention is to develop a cigarette with a gas phase active filter which can be produced very efficiently and at the same time inexpensively.
- the invention thus relates to a filter cigarette with a filter containing activated carbon with: a) a tobacco rod surrounded by a cigarette paper; b) a double filter, in which the strand-side part consists of a carbon-containing tissue paper, and with c) a circumferential filter ventilation zone in the mouth-side part made of cellulose acetate; d) the tissue paper of the strand-side filter part is a very voluminous paper which contains 20 to 50% by weight of microfine ground activated carbon; e) the ratio of the condensate retention performances of the strand-side to the mouth-side filter part is between 1 and 2; f) the air permeability of the cigarette paper is 40 to 100 Coresta units; and g) the degree of filter ventilation is 5 to 60%.
- the cigarette paper porosity is 30 to 60% rel. higher than the cigarette paper porosity of a comparable cigarette produced with a conventional filter and the degree of filter ventilation is 10 to 60% rel. lower than the degree of filter ventilation of a comparable cigarette made with a conventional filter.
- the tissue paper has a basis weight of approx. 40 - 60 g / m 2 , an activated carbon content of 15 - 50% and a thickness of 150 200 ⁇ m.
- a preferred variant has a weight per unit area of 50 g / m 2 and an activated carbon content of 30% by weight with a thickness of 180 ⁇ m.
- the strand-side filter part of the double filter is a core filter according to DE 42 05 658 C2, in which the core is made of carbon-containing tissue paper as in the first-mentioned embodiment, which is surrounded by a jacket made of material which is almost impermeable to the mainstream smoke .
- This almost smoke-impermeable material consists, for example, of highly compressed cellulose acetate fibers.
- the cigarettes C and D differed in the same way in the reactivity, whereby the tobacco flavor of variant D was more pronounced.
- the F variant was significantly less reactive, but had an increased tobacco aroma.
- the mouth-side filter part in addition to the known acetate monofilter: for example, a coaxial construction of the mouth-side filter part is known to offer the possibility of simultaneously providing the desired retention and the desired open one Optimally adjust the drag of the cigarette independently.
