Description

Components for aerosol supply items The present invention relates to a component for an aerosol-providing article. Popular aerosol-generating articles may have a substantially cylindrical rod-shaped structure and may include a filler, roll, or column of smokeable material, such as shredded tobacco (e.g., in the form of a cut filler), surrounded by a paper wrapper, thereby forming a rod of aerosolizable material. Typically, the aerosol-generating article has a filter element aligned with the rod of aerosolizable material in an end-to-end relationship. Generally, the filter element comprises a rod of plasticized cellulose acetate tow surrounded by a paper material known as a plug wrap, and the filter is attached to one end of the rod of aerosolizable material using a surrounding wrapping material known as a tipping material. In one aspect of the present invention, a component for an aerosol providing article for use in an aerosol providing system is provided. The component comprises a body of a material having an annular cross section and comprising a plurality of fibers formed from regenerated cellulose. In some embodiments, the annular body of the material may form an outer section of the component. In some embodiments, the annular body of the material may be extended longitudinally through a component. In some embodiments, the component may further include a core section extending longitudinally. In some embodiments, the outer section may extend longitudinally around the core section. In some embodiments, the core section and the outer section may be formed coaxially. In some embodiments, the core section may be formed by a cavity defined by the inner surface of the outer section. In some embodiments, the core section may include a tubular element having a cavity. In some embodiments, the cavity may be configured to accommodate a heating element. In some embodiments, the tubular element may be configured to maintain a gap from the heating element when the heating element is inserted into the tubular element. In some embodiments, the cavity may extend for the entire length of the core section. In some embodiments, the inner surface of the tubular element may be embossed, and optionally, the embossed portion may be configured to minimize contact with the heating element when the heating element is inserted into the tubular element. In some embodiments, the tubular element may have a hardness in the range of about 50% to about 90%. In some embodiments, the core section may be formed from a paper material. In some embodiments, multiple fibers of the outer section may be hydroentangled. In some embodiments, a plurality of fibers of the outer section may be wet-laid. In some embodiments, the component may further comprise a binder. In some embodiments, the component may comprise 2% to 10% by weight of the component for an aerosol providing article. In some embodiments, the binder may comprise pectin. In some embodiments, the component may comprise 4% pectin by weight of the component. In some embodiments, the component may further include a plasticizer. In some embodiments, the plurality of fibers may have a bulk density in the range of about 0.1 g/ cm³ to about 0.4 g/ cm³ . In some embodiments, a plurality of regenerated cellulose fibers may have a denier per filament in the range of about 1 dpf to about 30 dpf. In some embodiments, the plurality of fibers may include a first plurality of regenerated cellulose fibers and a second plurality of regenerated cellulose fibers, and the first plurality of regenerated cellulose fibers may have a greater denier per filament than the second plurality of regenerated cellulose fibers. In some embodiments, the first plurality of regenerated cellulose fibers may have a denier per filament in the range of about 10 dpf to about 30 dpf, and the second plurality of regenerated cellulose fibers may have a denier per filament in the range of about 1 dpf to about 10 dpf. In some embodiments, the plurality of regenerated cellulose fibers comprises a first plurality of regenerated cellulose fibers in a range of about 60% to about 90% by weight and a second plurality of regenerated cellulose fibers in a range of about 10% to 40% by weight. In some embodiments, the plurality of fibers may be discontinuous and optionally may have fiber lengths ranging from about 30 mm to about 60 mm. In some embodiments, the largest dimension of the cross-section of each filament may be greater than 10 μm. In some embodiments, a plurality of fibers may be crimped. In some embodiments, the material may be in the form of a nonwoven sheet gathered to form rod-shaped elements. In some embodiments, the nonwoven sheet may be non-pleated and not crimped when gathered to form rod-shaped elements. In some embodiments, the material may be in the form of a plurality of nonwoven sheets gathered to form a rod-shaped element. In some embodiments, the plurality of nonwoven sheets may not be crimped or wrinkled when ga
