The present disclosure relates to a lyocell material for a cigarette filter and a method of manufacturing the same, in which, by setting the optimal total denier range of crimped lyocell tow, which may realize filter properties equivalent to cellulose acetate (CA) currently used as a cigarette filter, the optimal processability for manufacturing a cigarette filter may be secured, and due to the excellent biodegradability thereof, environmental pollution factors caused by conventional discarded cigarette butts may be reduced.

A method of operating a filter rod making machine comprising disposing a plurality of stations laterally of the filter making machine, placing a bale of tow at each of the laterally disposed plurality of stations, drawing tow from above each of the placed plurality of bales into the filter rod making machine in succession, and upon depletion of tow from the placed plurality of bales, replacing the depleted plurality of bales as a set. The drawing of tow may include, for each bale, drawing tow from above the respective bale with a station guide operative at the respective, laterally disposed station and drawing the tow transversely from the respective station guide to a machine-based guide adjacent the filter rod making machine. The disclosure also provides associated apparatus, including a system for making a filter rod and a boom assembly of a tow conditioning section of a system for making a filter rod.

A smoking article includes a smokable material and a filter downstream of the smokable material. The filter includes activated carbon material having a BET of between 1000 and 2000 m.sup.2/g and exhibiting less particle breakthrough than granulated coconut shell derived activated carbon currently used for filters of smoking articles.

The present invention relates to a cigarette filter and a method for manufacturing same, and can provide a paper cigarette filter using paper and a cigarette comprising same. A cigarette filter according to one embodiment of the present invention can impart a high degree of smoking satisfaction through high granule stability, and eliminate a burnt taste. Hereinafter, various embodiments related to a cigarette filter and a method for manufacturing same may be possible.

This filler element 6 is used in a flavor inhaler 1, and comprises: a folded part 36 in which one sheet 34 composed of a nonwoven fabric has been folded in the width direction Z intersecting the longitudinal direction X thereof, and the diameter thereof has been reduced to a size not greater than the diameter of the filler element 6; and wrapping paper 18 that is wrapped on the folded part 36. The sheet 34 is subjected to a drawing process in the longitudinal direction X.

A filter substrate and binder filter rod making process with multiple connecting binding areas or binders throughout the filter substrate or other biodegradable materials, mono-fiber or multi-fiber, regardless of whether the paper(s)/substrate(s) has been crimped, embossed, or not, which improve the substrate properties including mechanical strength, filtration capability for both vapor/gases and particulate/solids phases, TAR, Nicotine and especially Carbon Monoxide, sensorial neutrality, visual improvements before and after use and substrate processability.

A system configured to produce smokable products including filter elements formed from multiple fibers is provided. The system includes a texturing apparatus configured to combine the fibers such that the fibers are at least partially entangled with each other and form a mixed fiber product. The entangled fibers may be sufficiently separated from one another such that plasticizer may be applied to the mixed fiber product without necessarily performing tow opening, crimp removal, or blooming operations. The fibers combined to form the mixed fiber product may define characteristics that differ or which are the same. Accordingly, filter elements may be produced that include different fibers that have respective desirable properties associated therewith. Related methods, apparatuses and mixed fiber products are also provided by the disclosure.

Shown is a filter material for manufacturing a segment for a smoking article, wherein the filter material is web-shaped and contains at least 50% and at most 100% cellulose fibers, each with respect to the mass of the filter material, wherein the filter material has a basis weight of at least 15 g/m.sup.2 and at most 60 g/m.sup.2, wherein the thickness of one layer of the filter material, measured in accordance with ISO 534:2011, is at least 25 m and at most 1000 m, wherein the filter material has a machine direction and a cross direction orthogonal thereto and lying in the plane of the web of the filter material, and wherein the filter material has a characteristic plastic deformability in the cross direction which is characterized in that in a tensile test in the cross direction in accordance with ISO 1924-2:2008, the nonlinear portion of the deformation energy absorbed by the filter material up to half the elongation at break is at least 10% and at most 50% of the total deformation energy absorbed by the filter material up to half the elongation at break.

There is provided a method of making rods having predetermined values of cross-sectional porosity, and a cross-sectional porosity distribution value for use as an aerosol-forming substrate in a heated aerosol-generating article, including providing a continuous sheet of aerosol-forming material having a specified width and a specified thickness; gathering the sheet transversely relative to a longitudinal axis thereof; circumscribing the gathered sheet with a wrapper to form a continuous rod; severing the rod into a plurality of discrete rods; determining values of cross-sectional porosity and cross-sectional porosity distribution for at least one of the discrete rods; and controlling one or more manufacturing parameters to ensure that the cross-sectional porosity and cross-sectional porosity distribution values of subsequent rods are within the predetermined values.

A cooling cigarette filter and a cigarette are disclosed. The cooling cigarette filter comprises a cooling section (2). The cooling section (2) comprises a cooling stick (201) formed from paper (5). The cooling stick (201) has one or more holes (202) communicating two ends of the cooling stick. And the surface of the paper (5) is coated with a cooling material. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly And the temperature of the high-temperature smoke before entering the mouth can be significantly lowered, thereby improving the comfort and satisfaction of smoking.
