Abstract
A tow band for heated tobacco product tip is a tow band of cellulose acetate provided by uniting and crimping a plurality of filaments into a bundle, in which a total denier is set to a value in a range of 10000 to 40000 (inclusive) and a filament denier is set to a value in a range of 6.0 to 20.0 (inclusive), and where the total denier is denoted by TD and a breaking strength of the tow band is denoted by F, a ratio F/TD is set to a value of 0.0015N/denier or more.
