Abstract
Disclosed are cellulose acetate tows, bales, and filter rods having from greater than 9 to less than 12.5 denier per filament and from 20,000 to 40,000 total denier, for use in smoking devices, including aerosol-generating devices such as an electrically heated cigarette.
Claims16
An aerosol-generating device comprising:
- an aerosol-generating article, wherein the aerosol-generating article comprises:
- an aerosol-forming substrate;
- a support element;
- an aerosol-cooling element;
- a mouthpiece, wherein the mouthpiece comprises a cellulose acetate tow rod having from greater than 9 to less than 12.5 denier per filament and from 20,000 to 40,000 total denier;
- and
- wherein the cellulose acetate tow rod has a hardness of at least 85%.
The aerosol-generating device of any of the preceding claims, wherein the cellulose acetate tow has a bale UCE from 200 g-cm/cm to 370 g-cm/cm.
The aerosol-generating device of any of the preceding claims, wherein filaments of the cellulose acetate tow rod have a cross-sectional shape selected from the group comprising circular, substantially circular, crenulated, ovular, substantially ovular, polygonal, substantially polygonal, dog-bone, “Y,” “X,” “K,” “C,” multi-lobe, and any combination thereof.
A tow bale comprising a tow band, wherein the tow band comprises cellulose acetate tow having from greater than 9 to less than 12.5 denier per filament and from 20,000 to 40,000 total denier and wherein the tow bale has a process UCE from 280 g-cm/cm to 330 g-cm/cm.
