  • Patent number: 8602036
    Abstract: A large variety of electrospun fibers can be produced to encapsulate a large variety of additives within the subcompartments or substructures of the manufactured electrospun fiber. Furthermore, the manufactured electrospun fibers can be electrostatically arranged within a filter component of a smoking article during the manufacturing process. By modifying the various parameters that control the electrospinning process, a diverse set of electrospun fibers can be manufactured that vary in composition, in substructural organization, and in dimension. The electrospun fiber produced by electrospinning comprises at least one type of polymeric material that encapsulates or supports the retention of at least one type of a flavorant or a non-flavorant within the electrospun fiber. A polymeric material provides a supporting structure for encapsulating at least one type of a flavorant or a non-flavorant.

  • Publication number: 20130014774
    Abstract: A filter material of a filter element configured for application in a smoking article may include a fibrous substrate material finished with a fiber finish composition. The fiber finish composition may be formulated to selectively interact with at least one target component of mainstream smoke drawn through the filter element during use of the smoking article to selectively filter the target component from the smoke. The filter element may include multiple filter segments. Each filter segment may include a filter material having a finish composition formulated to selectively interact with a different target component. The various filter segments may be combined and/or arranged to selectively filter the mainstream smoke to achieve desired characteristics. Each filter segment may be formed from the same fibrous substrate material.

  • Publication number: 20120318286
    Abstract: A biodegradable cigarette filter has a filter tow surrounded by one or more wrapper layers. The filter tow is a mixture of hemp, a second fibrous material comprising cotton, paper, or a mixture of cotton and paper, and a thickening and bonding agent comprising flour or starch initially added to the mixture as a solution in water. The mixture of hemp and the second fibrous material in the filter tow act as a filtering matrix for the cigarette smoke when consumed by a user. In one example, two wrapper layers comprising a plug wrap and a tipping paper surround the filter tow. The filter tow or one or both wrapper layers, or both the tow and wrapper layers, may contain plantable seeds.

  • Publication number: 20120255569
    Abstract: The invention provides a cigarette with a filter element comprising at least one longitudinally extending section of filter material. The section of filter material comprises a smoke-altering material therein that is useful for removing a quantity of vapor phase chemicals from the mainstream smoke. The section of filter material further comprises one or more tubes inserted into and extending through section of filter material. The one or more tubes each define a channel adapted for passage of mainstream smoke through the section of filter material while substantially avoiding contact of the portion of mainstream smoke therein with the smoke-altering material. The provision of a portion of mainstream smoke substantially unaltered by the smoke-altering material can be useful to retain certain desirable taste and other sensory properties of the mainstream smoke.
