Abstract
Official abstract text for this publication.
A cigarette for an aerosol generating device includes a tobacco rod including an aerosol generating substrate wrapped with a wrapper and a filter through which an aerosol generated from the aerosol generating substrate passes. The filter comprises cellulose acetate tow having a total denier of a preset value.
First claim
Opening claim text (preview).
1 . A cigarette for an aerosol generating device, comprising: a tobacco rod including an aerosol generating substrate wrapped with a wrapper; and a filter through which an aerosol generated from the aerosol generating substrate passes, wherein the filter comprises cellulose acetate tow having a total denier in a range of 22,000 to 25,000. 2 . (canceled) 3 . The cigarette for an aerosol generating device of claim 1 , wherein the total denier is 25,000. 4 . The cigarette for an aerosol generating device of claim 1 , wherein the filter is a cellulose acetate tow filter comprising cellulose acetate tow having a mono denier of a preset value less than or equal to 13. 5 . The cigarette for an aerosol generating device of claim 4 , wherein the mono denier is in a range of 9 to 13. 6 . The cigarette for an aerosol generating device of claim 1 , wherein the filter comprises acetate tow having a Y-shaped cross-sectional area. 7 . The cigarette for an aerosol generating device of claim 1 , wherein the filter comprises acetate tow having an O-shaped cross-sectional area. 8 . The cigarette for an aerosol generating device of claim 6 , wherein the filter is a cellulose acetate tow filter comprising cellulose acetate tow having a mono denier in a range of 10 to 12. 9 . The cigarette for an aerosol generating device of claim 6 , wherein the filter is a cellulose acetate tow filter comprising cellulose acetate tow having a mono denier of 11.7. 10 . The cigarette for an aerosol generating device of claim 7 , wherein the filter is a cellulose acetate tow filer comprising cellulose acetate tow having a mono denier of 9. 11 . The cigarette for an aerosol generating device of claim 1 , wherein the filter is a cellulose acetate tow filter comprising cellulose acetate tow to which a plasticizer in a range of 12% to 24% is applied. 12 . The cigarette for an aerosol generating device of claim 1 , wherein the cellulose acetate tow has a mono denier of a reference value, and the reference value is a value that lowers suction resistance of the filter to be lower than a preset value. 13 . The cigarette for an aerosol generating device of claim 1 , wherein the cellulose acetate tow has a mono denier of a reference value, and the reference value is a value that raises hardness of the filter to be greater than a pre-set value. 14 . An aerosol generating device which generates aerosol by heating the cigarette according to claim 1 . 15 . The cigarette for an aerosol generating device of claim 7 , wherein the filter is a cellulose acetate tow filter comprising cellulose acetate tow having a mono denier in a range of 10 to 12.
