The mechanism of cigarette smoldering was studied. Images of a smoldering cigarette taken by CCD camera were analyzed to characterize the propagation of cigarette smoldering. Cigarette smoldering does not occur in a steady state. Propagation of...

This paper describes Philip Morris USA's development of a new type of banded cigarette paper which may reduce the ignition propensity (IP) of cigarettes when the cigarettes are placed upon certain test fabrics. Several approaches to reduce IP have...

Papers for the cigarette industry contain a sophisticated mixture of mineral fillers, each one serving a special purpose. Yet, not only the type and amount but also the distribution of the individual fillers influence paper properties like e.g....

Porosity, resistance to airflow, thickness, and basis weight, are important characteristics of cigarette paper. Variations in microstructure and composition, which contribute to differences in airflow impedance and porosity, typically manifest...

Triacetin is the most commonly used plastiziser for cellulose acetate filters. To get a sufficient hardness target values for triacetin vary typically between approximately 6 and 9 % of the total filter weight. The application takes place in a...

In the past, several authors published the results of experiments concerning the flow of air through perforated and unperforated papers, filters, and tobacco rods. The pressure drop-flow relations obtained by these experiments showed a significant...

Cigarette filters represent a major challenge to researchers in the cigarettes industry, having in mind the effects of smoking upon the human organism. This paper discusses an analysis of filter materials used in the world and the parameters that...

Filter pressure drop variability influences the variability of cigarette pressure drop but, at typical levels, does not significantly affect smoke delivery variability or ventilation variability. A detailed statistical characterization of typical...

The pneumatic conveying dryer has been in general use for drying or expanding cut tobacco in the cigarette industry because of high heat-transfer efficiency. So it is an important matter to clarify the phenomenon of heat / mass transfer of cut...

The hardness measurement is not specific to the tobacco world. It can be found in areas as diverse as engineering, ergonomics, fruit and vegetable farming, etc. In addition, the way in which the consumer judges the quality of this parameter varies...
