From the viewpoint of the quality evaluation of cigarettes, the firmness of cigarette is one of the most important properties. It has high correlation to physical properties and to the form of the cut tobacco assembly under the compressive condition.
In this report, the effect of the form of shred on the compressive characteristics has been studied for model specimens amenable to mathematical treatments, which were cut out from the uniform sheet reconstituted with the fibrous composition of tobacco leaf, instead of cut tobacco.
The following results were obtained experimentally.
1) The form of shred can be expressed by Ev, the ratio of the exclusive volume to the real volume of specimen.
2) The relationship between compressive stress P and void fraction ε can be expressed by the following equation in the P range of 100-500g/cm2,
P=α(1-ε)n
where, α and n are constants.
3) The constant n tends to decrease with the increase in Ev.
