摘要:
Cigarettes are provided which contain a filtering system and flavorants encapsulated with polyvinyl acetate, wherein deactivation of a sorbent by the flavorant is reduced through the encapsulation of the flavorant within the polyvinyl acetate. A preferred flavorant is menthol. The encapsulated flavorants are prepared by mixing at least one flavorant with polyvinyl acetate and a solvent, such as ethanol, and forming the encapsulated flavorants. Methods of making cigarettes and smoking the articles are also provided.

A smoking article includes a cylinder of smoking material having at least one hollow tube having a heat conductive wall within the cylinder of smoking material and a filter system attached to the cylinder of smoking material. The filter system includes an adsorbent material therein. The at least one hollow tube extends from within the cylinder of smoking material through the adsorbent material. At least one flavorant material is retained within the at least one hollow tube, and upon exposure to heat from the heat conductive wall of the hollow tube the flavorant material releases a flavorant.

A spinneret having tri-arc holes may be used to produce tri-arc filaments. In some instances, tri-arc holes have a Y-shape with three prongs and each prong having an arc at the end of the prong that tapers from the end of the arc to a connection point of an adjacent arc, and tri-arc filaments have a generally-Y shape cross-section with bulbous or arcing tips. Further, tri-arc filaments may be useful in a plurality of applications including, but not limited to, filters, filters comprising particulate additives, and smoking device filters.

Provided is a smoking article and method for reducing TPM cytotoxicity and targeted constituents in mainstream smoke. The smoking article includes tobacco material including a salt of a lanthanide metal. The method includes combining a salt of a lanthanide metal, water, and optionally glycerin to produce a solution that is applied to tobacco material. Preferably, the salt is an acetate, a sulfate, or a gluconate.

Fibers are produced from an acetone solution of cellulose acetate by pulling or extruding such material through a spinneret in a dry spinning process. A vacuum is applied to the thus formed fibers after a certain degree of drying. A dried outer skin is formed, and the vacuum causes the solvent inside the skin to explode or pop and exit the fiber along micro-porous paths thereby producing high surface area fibers with micro-porous cavities and internal void volume. Such micro-cavities are particularly useful for retaining solid and/or liquid reagents in a cigarette filter for selective filtration of various smoke components.
摘要:
The internal channels (22) of wicking fibers (20) are filled with a selected liquid (18) form of a prepolymerized polymer or monomers and related reagents and then the polymerization reaction is carried out under suitable conditions to form a fiber with desired properties. Fibers with the properties of the formed polymeric products are conveniently obtained thereafter. This provides a convenient way to obtain engineered fibers by directly polymerizing the monomers in the wicking fiber (20) channels (22). The wicking fibers (20) include internal longitudinal cavities or channels (22) each with a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected liquid, with which they comes into contact, through the internal cavities (22). The selected liquid remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers yet through the longitudinal openings (24) the liquid is in full communication with the environment surrounding the wicking fiber (20). The formed solid polymer is retained in the channels (22) of the wicking fiber (20).
