A filter for a smoking article includes a filter component formed from a solution of cellulose acetate and a degradable polymer in aceton, the degradable polymer being soluble in acetone and degrading in the presence of water. In a first aspect of the invention, the filter component is a filter segment (16) formed of a plurality of fibers formed from the degradable solution. In a second aspect of the invention, the filter component is a wrapper (39) circumscribing at least a segment of the filter.

A filter rod for a cigarette or other smoking article comprising a filter plug having a plurality of threads extending through at least part of the filter plug, and an apparatus and method for manufacturing such a filter rod.

A process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) freeze-drying a solution of a biopolymer to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby prepare a filter plug for a smoking article. Another process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) extruding a mixture of a foaming agent and a biopolymer comprising a protein to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby form a filter plug for a smoking article.

The non-combustible tobacco vaping insert includes a filter having a first diameter, and a non-combustible tobacco element with a first end contacting the filter. At least one first portion of the tobacco element has a second diameter that is smaller than the first diameter of the filter. The cartridge includes a heater configured to vaporize a pre-vapor formulation that is communicated to the heater by a wick. The insert is positioned in at least a portion of an air passage within cartridge, where the insert is configured to allow vapor that is generated by the heater to pass through the insert prior to being discharged from the cartridge.

A functional regenerated cellulose fiber includes a graphene structure and non-carbon non-oxygen elements. The non-carbon non-oxygen elements includes elements of Fe, Si, and Al. The elements of Fe, Si, and Al account for 0.018 wt % to 0.8 wt % of the regenerated cellulose fiber.

Disclosed are fibers which contain identification fibers. The identification fibers can contain a plurality of distinct features, or taggants, which vary among the fibers and/or along the length of the identification fibers, tow band, or yarn. The disclosed embodiments also relate to the method for making the fibers. Characterization of the fibers can include identifying distinct features, combinations of distinct features, and number of fibers with various combinations of distinct features and correlating the distinct features to supply chain information. The supply chain information can be used to track the fibers, fiber band, or yarn from manufacturing through intermediaries, conversion to final product, and/or the consumer.

A smoking article comprises a first part (111) comprising a source of smokable material and a second part (112) comprising a rod article and configured to be rotatable relative to the first part. A first indexing surface (116) on the first part and a second indexing surface (304) on the second part are configured to engage to index the rotation between the first and second parts. At least one of the first or second parts comprise a control element (250) configured to control a ventilation of the smoking article and a ventilation area (270) in the other of the first or second parts of the smoking article from the control element, the ventilation area configured to be selectively covered by the movable control element, wherein the second part comprises a connecting section connecting the rod article to the first part of the smoking article, and the connecting section is affixed to or supports the second indexing section.

A cartridge includes: a liquid storage that accommodates an aerosol generating material; an atomizer receives the aerosol generating material from the liquid storage and generates an aerosol from the aerosol generating material; a mouthpiece which is coupled to an end of the liquid storage and includes a discharge hole through which the aerosol generated from the aerosol generating material is discharged; a delivery tube arranged inside the liquid storage and connecting the discharge hole of the mouthpiece and the atomizer such that the aerosol generated in the atomizer is delivered to the discharge hole; and an absorbent element that is arranged on a delivery path of the aerosol between the delivery tube and the discharge hole, and absorbs a liquid.

Provided is a filling element used for a flavor inhalation article, the filling element including: a sheet fill section obtained by randomly gathering and reducing the diameter of one sheet in a width direction that intersects the longitudinal direction of the sheet; and, a roll paper wrapped around the sheet fill section. The sheet is a dry nonwoven fabric obtained by bonding plant-derived fibers together with a binder and drying the fibers.
