    The influence of storage conditions and packaging on acetic acid generation in cellulose acetate fibers

    TATUM C.E.; WILSON S.A.; CASPER R.G.; PEARCE M.J.
    Eastman Chemical Company, Kingsport, TN, U.S.A.
    The cellulose acetate polymer used in cigarette filters is made by acetylating wood pulp with acetic anhydride. One advantage of this modified natural polymer is that it readily degrades by multiple mechanisms. While the ultimate products are carbon ...

    Paper filters – the influence of different paper compositions and paper properties on filtration efficiency and pressure drop

    BACHMANN S.; GLEINSER M.; VOLGGER D.
    delfortgroup AG, Traun, Austria
    Smoke yields, smoke composition and the taste of a cigarette can be modified by changing different parts of the cigarette, especially the different filter design. Cellulose acetate is currently the most common material for cigarette filters, but also ...

    Using residual length data to estimate the rate of self-extinguishment of banded cigarettes

    EITZINGER B.(1); RIVAS CANO A.(2)
    (1) delfortgroup AG, Traun, Austria; (2) JT International Germany GmbH, Trier, Germany
    For non-banded lower ignition propensity (LIP) cigarettes the residual length of extinguished cigarettes has been shown to be useful to more precisely estimate the rate of self-extinguishment compared to just counting self-extinguished cigarettes (ISO ...

    Comparison of the cerulean e-cigarette pressure drop testing instrument to the ces 508 cigarette pressure drop and ventilation tester unit for electronic cigarettes, conventional tobacco burning cigarettes, and filter tips

    AVANTS K.W.(1); WILSON S.A.(2); CLARK J.(1)
    (1) Liggett Group, LLC, Mebane, NC USA; (2) Eastman Chemical Company, Kingsport, TN USA
    The pressure drop or “resistance to draw” of cigarettes and cigarette-like products is a prominent experience for consumers. This poster is a comparison of two commercial instruments with different approaches to measuring pressure drop. The instruments ...

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 1

    GLEINSER M.(1); EITZINGER B.(2); BACHMANN S.(1); VOLGGER D.(1)
    (1) Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria; (2) delfortgroup AG, Traun, Austria
    In the tobacco industry it is well known that porosity is one of the most significant physical properties of cigarette paper. There are indirect as well as direct methods to characterise this parameter. Measurement of the diffusion capacity and the air ...

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 2

    EITZINGER B.(1); GLEINSER M.(2); BACHMANN S.(2); VOLGGER D.(2)
    (1) delfortgroup AG, Traun, Austria; (2) Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Several publications have shown in the past, on theoretical grounds and by actual measurements, that the perforation of cigarette papers causes a substantial increase in air permeability, while the diffusion capacity increases comparably less. These ...
