Abstract: Disclosed herein is a tow band comprising cellulose acetate and a filler. The filler may be selected to have a degradation rate greater than that of the cellulose acetate. The tow band may be bloomed and formed into a filter rod, which may then be incorporated into a cigarette filter. The tow, tow band, and filter structures described herein degrade more rapidly than other known tow, tow bands, and filter structures.

Abstract: Disclosed herein is a degradable cigarette filter comprising a cellulose ester and including a catalyst comprising a basic material, an enzymatic material, or combinations thereof. The catalyst, when exposed to water, may deacetylate the bloomed cellulose acetate tow by at least 10% in 20 days or less. The filters described herein therefore degrade more rapidly than other known cellulose acetate tow filters.
