Abstract: The problem to be solved by the present invention is to prevent interruption of a cellulose acetate fiber during spinning of the cellulose acetate fiber thereby enhancing production efficiency of a cellulose acetate band. The cellulose acetate band according to an embodiment of the present invention is formed from cellulose acetate fibers, a total denier thereof is set to a value in a range from 8000 to 44000, a content of titanium oxide is set to a value in a range from 0 wt. % to 0.01 wt. %, and a content of a lubricant in the band measured by a diethyl ether extraction method is set to a value in a range greater than 5 mg but 65 mg or less per 1 m.

Abstract: Provided is a material (cigarette component) that enables the elimination or minimization of illicit cigarette production. Specifically, related is a cigarette filter tow band including a crimped bundle of filaments. The tow band includes a detectable marker for identifying the source of the tow band.
