    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: 20130319429
    Abstract: A filter element for a smoking article is described herein. The filter element may include at least one filter segment, the at least one filter segment comprising one or more flavoring or fragrancing particles configured to flavor or fragrance an aerosol from the smoking article, wherein the one or more flavoring or fragrancing particles are configured to adjustably release flavor or fragrance upon receipt of a pressure applied to the at least one filter segment while rolling the filter between fingers of a smoker, and wherein the quantity of flavor or fragrance released is proportional to an amount of pressure applied while rolling the filter. Thus, a user is able to control the amount of flavoring or fragrance provided during a smoking experience.
