Mathematical Models to Analyse the Effect of Physical Properties of Cigarettes on the Propensity Of the Cigarette to Ignite Cellulosic Fabrics

摘要

A series of 37 cigarettes were analysed to develop a model, based on cigarette physical properties, to predict the ignition propensity of the cigarettes towards cellulosic fabrics. The properties used were: cigarette circumference (in mm), tobacco packing density (in g cm~-2), paper permeability (in CORESTA units) and the presence or absence of citrate additives in the paper (used independent of concentration, although typical additions range from 0.5 to 0.8 wt/100). Two empirical models were developed, one for low and medium paper permeabilities, and one for very high paper permeabilities (above 50 CORESTA units).
