摘要
A cellulose acetate tow band for use in a cigarette filter, in which a filament denier is not less than 5.0 denier, a Feret area of a filament is not less than 0.5, and/or a ratio S/L of a cross-sectional area S of the filament to a cross-sectional peripheral length L of the filament is not less than 5. The filament denier may be not more than 10 denier. The Feret area may be not more than 0.9. The ratio S/L may be not more than 9. In an apparatus for or a method of manufacturing a tow band, round-shaped spinning holes (10) each with a diameter of not less than 50 µm are used. The diameter of each round-shaped spinning hole (10) may be not more than 100 µm.
