Abstract: Disclosed are cellulose acetate tows, bales, and filter rods having from greater than 9 to less than 12.5 denier per filament and from 20,000 to 40,000 total denier, for use in smoking devices, including aerosol-generating devices such as an electrically heated cigarette.

Abstract: Disclosed are packaged fibrous material bales and methods for packaging fibrous materials such as cellulose acetate tow bales. The packaged fibrous material bale may comprise a compressed fibrous material enclosed in packaging. The packaging may comprise an upper sheet and a lower sheet comprising a tab. After the residual forces in the packaged bale have equilibrated following pressing, greater than 99% of the surface area of the bale is enclosed by the packaging.

Abstract: Disclosed are cellulose acetate cellulose acetate tow and processes for making cellulose acetate tow having at least 15 denier per filament, e.g., at least 20 denier per filament, or at least 25 denier per filament. The cellulose acetate tows may have total denier of more than 20,500.

Abstract: Disclosed are methods for packaging fibrous materials such as cellulose acetate tow bales. The method may comprise placed a fibrous material between an upper sheet and a lower sheet, folding the upper and lower sheets around the fibrous material, and connecting the upper sheet and lower sheet with a tape, such as a pressure sensitive adhesive tape.

Abstract: In the manufacture of a fiber tow, particularly cellulose acetate tow, the tow is plasticized prior to entry into the crimper. The preferred plasticizer is water.

Abstract: An apparatus and process for making a cigarette tow comprising: means for spinning a dope comprising a solution of cellulose acetate and solvent; means for taking-up the as-spun cellulose acetate filaments; means for lubricating the cellulose acetate filaments; means for forming a tow from the cellulose acetate filaments; means for crimping the tow, the means for crimping comprising a stuffer box crimper comprising a pair of nip rollers adapted to engage the tow, a pair of cheek plates juxtaposed to the pair of nip rollers adapted to keep the tow between the pair of nip rollers, a pair of doctor blades adjacent to an exit end of said pair of nip rollers, and a stuffer box having a stuffer channel adjacent the pair of doctor blades adapted to receive the tow into the channel from the pair of nip rollers, a flapper located at a distal end of the channel adapted to bearingly engage the tow; means for drying the crimped tow; and means for baling the dried crimped tow.
