[0002] Popular aerosol-generating articles can have a generally cylindrical rod-like structure and can include a pack, roll, or column of a smokeable material, such as shredded tobacco (e.g., in the form of cut filler), surrounded by a paper wrapping, thus forming a rod of aerosolizable material. Typically, aerosol-generating articles have a filter element aligned end-to-end with the rod of aerosolizable material. The filter element typically comprises a rod of plasticized cellulose acetate filaments surrounded by a paper material called plug wrap, and the filter tip is attached to one end of the rod of aerosolizable material using an outer wrapping material called tipping material.

Detailed Implementation

[0051] For reference Figure 1 It shows that in Figure 3 The aerosol supply product 3 shown is used as such Figure 2 The material 1 of component 2 shown is provided. In one aspect of the invention, a material 1 comprising a plurality of fibers 5 is provided. The plurality of fibers 5 comprise regenerated cellulose fibers. Material 1 has a content of approximately 0.1 g / cm³. 3 To approximately 0.40 g / cm 3 The volume density within the specified range.

[0052] The multiple regenerated cellulose fibers 5 can be discontinuous fibers. The multiple fibers can be spunlace.

[0053] The bulk density of multiple fibers 5 of regenerated cellulose can be calculated without considering any other characteristics of material 1, component 2, or article 3 when material 1 is formed into part 2 or article 3, such as packaging material, aerosol generating material, aerosol modified component, or other component.

[0054] As described above, material 1 can have a content of about 0.10 g / cm³. 3 To approximately 0.40 g / cm 3 The bulk density is within the range of [specific parameters]. In some embodiments, material 1 may have a bulk density of approximately 0.10 g / cm³. 3 To approximately 0.30 g / cm 3 The bulk density is within the range of [specific values]. In some embodiments, material 1 may have a bulk density of approximately 0.13 g / cm³. 3 To approximately 0.18 g / cm 3 The bulk density is within the range specified. In some embodiments, material 1 may have a bulk density of about 0.15 g / cm³. 3 Approximately 0.17 g / cm³ 3 The volume density.

[0055] The bulk density of material 1 can be customized to provide a satisfactory pressure drop for the user when the material is formed into part 2 for use in article 3 or in article 3. Furthermore, the reduction in the bulk density of material 1 improves cost efficiency and material usage, and thus reduces the manufacturing impact on the environment.

[0056] It should be understood that although the plurality of fibers 5 have been previously described as containing regenerated cellulose, it is possible that the plurality of fibers 5 forming the material 1 are composed of or are substantially composed of regenerated cellulose fibers.

[0057] In some embodiments, the component 2 formed from the filter material 1, which is formed from the fibers 5 of regenerated cellulose, can be a filter element. In this sense, material 1 can be considered a filter material. In some embodiments, the component 2 formed from the material 1, which is formed from the fibers 5 of regenerated cellulose, can be a component different from a filter element. For example, the component 2 formed from material 1 can be included in the aerosol supply article 3 to help achieve the required pressure drop on the aerosol supply article 2.

[0058] In some embodiments, material 1 may be provided in the form of a nonwoven sheet. The nonwoven sheet may contain a plurality of discontinuous fibers 5. Material 1 may be assembled into any desired form to form part 2. Part 2 may form the filter segment and / or aerosol generating portion of article 3, which may be configured to be heated to release aerosols via, for example, an aerosol generating device. A plurality of regenerated cellulose fibers 5 may advantageously provide increased biodegradability compared to fiber types typically used for, for example, filter portions of conventional cigarettes (e.g., cellulose acetate).

[0059] The plurality of regenerated cellulose fibers 5 may be the only type of fiber present in material 1. That is, the plurality of fibers 5 in material 1 may consist of regenerated cellulose fibers. As used herein, the term "fiber" may be defined as a basic element of textiles. It should be noted that the filter material of the present invention may comprise the disclosed fiber 5 alone or a combination of the disclosed fiber 5 with one or more other fiber inputs. Fibers may be in the form of rope-like or thread-like elements. The term "fiber" is intended to include fibers, filaments, etc.

[0060] Regenerated cellulose can be considered a class of materials manufactured by converting natural cellulose into soluble cellulose derivatives or by directly dissolving cellulose pulp and subsequently regenerating it via a wet spinning process. Therefore, regenerated cellulose fibers can be considered a class of materials manufactured by converting natural cellulose into soluble cellulose derivatives or by directly dissolving cellulose pulp and subsequently regenerating it in fiber form. The main difference between regenerated cellulose fibers and known materials used in filter tips (such as cellulose acetate) is that regenerated cellulose fibers are in pure cellulose form, while cellulose acetate fibers are a modified form of cellulose obtained by adding acetyl groups to the cellulose polymer.

[0061] Regenerated cellulose fibers are typically prepared by extracting non-cellulose compounds from wood, contacting the extracted wood with caustic soda, followed by carbon disulfide, and then with sodium hydroxide, to obtain a viscous solution by directly dissolving high-purity cellulose pulp using NMMO. The solution is then pushed through a spinneret to produce viscous threads of regenerated fibers. The method of preparing regenerated cellulose is not considered to limit the scope of the invention. The various regenerated cellulose fibers 5 can be, for example, but not limited to, viscose, lyocell, rayon, viscose rayon, cuprammonium cellulose, and modal.

[0062] In some embodiments, the plurality of fibers 5 may be composed of regenerated cellulose. In some embodiments, the plurality of fibers 5 may comprise 90% to 100% by weight of the fibers contained within the material.

[0063] In some embodiments, the plurality of regenerated cellulose fibers 5 are composed of lyocell and are the only fibers included in material 1. In some embodiments, the plurality of regenerated cellulose fibers 5 are composed of viscose fibers and are the only fibers included in material 1.

[0064] The denier / filament of multiple regenerated cellulose fibers 5 can range from 1 to 30 denier / filament (dpf). Denier / filament or denier / fiber is a measurement of the weight per unit length of a single filament of the fiber. The denier of a regenerated cellulose fiber is expressed in grams per 9000 meters. The denier of the filament can be manipulated or selected to achieve a desired pressure drop across material 1 or across a component 2 formed from material 1 (such as a filter element formed from multiple regenerated cellulose fibers 5).

[0065] In some embodiments, the denier / filament of the plurality of regenerated cellulose fibers 5 can be in the range of about 1 dpf to about 20 dpf. In some embodiments, the denier / filament of the plurality of regenerated cellulose fibers 5 can be in the range of about 1 dpf to about 10 dpf.

[0066] In some embodiments, the denier / filament range for the plurality of regenerated cellulose fibers 5 may be from about 1 dpf to about 8 dpf, or from about 1 dpf to about 6 dpf, or from about 1 dpf to about 5 dpf, or from about 1 dpf to about 4 dpf, or from about 1 dpf to about 3 dpf. In some embodiments, the denier / filament range for the plurality of regenerated cellulose fibers 5 may be from about 1.5 dpf to about 10 dpf, or from about 1.5 dpf to about 6 dpf, or from about 1.5 dpf to about 5 dpf, or from about 1.5 dpf to about 4 dpf, or from about 1.5 dpf to about 3 dpf.

[0067] In some embodiments, the plurality of regenerated cellulose fibers 5 of material 1 may comprise a first plurality of regenerated cellulose fibers and a second plurality of regenerated cellulose fibers. The dpf of the first plurality of regenerated cellulose fibers may be greater than that of the second plurality of regenerated cellulose fibers. The first plurality of regenerated cellulose fibers may be formed from regenerated cellulose fibers with a single filament denier of about 10 dpf to about 30 dpf. The second plurality of regenerated cellulose fibers may be formed from regenerated cellulose fibers with a single filament denier of about 1 dpf to about 10 dpf.

[0068] In some embodiments, the first plurality of regenerated cellulose fibers 5 may be formed from regenerated cellulose fibers with a denier of about 15 dpf to about 30 dpf, and the second plurality of regenerated cellulose fibers 5 may be formed from regenerated cellulose fibers with a denier of about 1 dpf to about 6 dpf.

[0069] In some embodiments, the first plurality of regenerated cellulose fibers 5 may be formed from regenerated cellulose fibers with a denier of about 18 dpf to 27 dpf. In some embodiments, the first plurality of generated cellulose fibers 5 may be formed from regenerated cellulose fibers with a denier of about 20 dpf to about 25 dpf.

[0070] In some embodiments, the second plurality of regenerated cellulose fibers 5 may be formed from regenerated cellulose fibers having denier / filament in the range of about 1 dpf to about 5 dpf, about 1 dpf to about 4 dpf, about 1 dpf to about 3 dpf, or about 1 dpf to about 2 dpf.

[0071] In some embodiments, the ratio of the first plurality of regenerated cellulose fibers to the second plurality of regenerated cellulose fibers, by weight, may be in the range of about 90:10 to about 60:40. In some embodiments, the plurality of fibers 5 may comprise a first plurality of regenerated cellulose fibers ranging from about 60 wt% to about 90 wt% and a second plurality of regenerated cellulose fibers ranging from about 10 wt% to about 40 wt%. For example, material 1 may be formed from about 20% of 1.5 dpf regenerated cellulose fibers and 80% of 25 dpf regenerated cellulose fibers.

[0072] In some embodiments, the plurality of regenerated cellulose fibers 5 may comprise more than two types of fibers with different denier numbers. In some embodiments, the plurality of regenerated cellulose fibers 5 may include a first plurality of regenerated cellulose fibers having a denier number of about 5 dpf to about 10 dpf, a second plurality of regenerated cellulose fibers having a denier number of about 2 dpf to about 5 dpf, and a third plurality of regenerated cellulose fibers having a denier number of less than about 2 dpf.

[0073] The first plurality of regenerated cellulose fibers 5 may account for approximately 30% to approximately 60% of the weight of material 1. The second plurality of regenerated cellulose fibers 5 may account for approximately 25% to approximately 30% of the weight of material 1. The third plurality of regenerated cellulose fibers 5 may account for approximately 5% to 20% of the weight of material 1.

[0074] For example, in one embodiment, the plurality of regenerated cellulose fibers 5 may comprise a first plurality of regenerated cellulose fibers having a monofilament denier of about 5.4 dpf, a second plurality of regenerated cellulose fibers having a monofilament denier of about 2.7 dpf, and a third plurality of regenerated cellulose fibers having a monofilament denier of about 1.4 dpf. The three types of regenerated cellulose fibers may be present in a weight ratio of 40:40:20.

[0075] In another embodiment, the plurality of regenerated cellulose fibers 5 may comprise a first plurality of regenerated cellulose fibers having a monofilament denier of about 5.4 dpf and a second plurality of regenerated cellulose fibers having a monofilament denier of about 2.7 dpf. The two types of regenerated cellulose fibers may be present in a weight ratio of 40:60.

[0076] In another embodiment, the plurality of regenerated cellulose fibers 5 may comprise a first plurality of regenerated cellulose fibers having a monofilament denier of about 5.4 dpf, a second plurality of regenerated cellulose fibers having a monofilament denier of about 2.7 dpf, and a third plurality of regenerated cellulose fibers having a monofilament denier of about 1.4 dpf. The three types of regenerated cellulose fibers may be present in a weight ratio of 60:30:10.

[0077] It has been found that combinations of first and second regenerated cellulose fibers with different monofilament deniers, and optionally additional plurality of other regenerated cellulose fibers, improve the tensile strength of the material, which in turn improves the operability of material 1 in manufacturing equipment such as filter manufacturing machines. Furthermore, combinations of first plurality of regenerated cellulose fibers and second plurality of regenerated cellulose fibers with different monofilament deniers allow for adjustment of filtration efficiency and pressure drop on components 2 formed from material 1, as well as the stiffness and elasticity of the nonwoven material.

[0078] By adjusting the stiffness and elasticity of material 1, the variability of material 1 can be reduced, allowing material 1 to be aggregated in a more consistent manner, which in turn provides a more consistent pressure drop across the component 2 formed from material 1. The greater flexibility associated with spunlace regenerated cellulose materials results in a lower void fraction in the components formed from said spunlace regenerated cellulose materials. Generally, the greater the material stiffness, the greater the void fraction.

[0079] The porosity can be considered as the amount of space between materials when the material is aggregated into components, compared to the cross-sectional area of ​​the component. When aggregated into components, the porosity of the material can range from about 5% to about 30%, depending on the fiber's dpf.

[0080] For a dpf range of about 1 to about 5 dpf, the porosity can be in the range of about 5% to about 10%. For a dpf range of about 15 to about 25 dpf, the porosity can be in the range of about 20% to about 30%.

[0081] In some embodiments, the plurality of regenerated cellulose fibers 5 may be short fibers. That is, the plurality of regenerated cellulose fibers 5 may be discontinuous. In other words, when the fibers are formed, they may be formed as discrete fibers of a specific length. This is in contrast to the formation of a tow used in a delivery system, where the tow is manufactured into long, continuous fibers through a stretching process. In some embodiments, the length of the plurality of short regenerated cellulose fibers 5 may be in the range of about 30 mm to about 60 mm. The length of the regenerated cellulose fibers may be considered as the extended length or pre-crimped length of the regenerated cellulose fibers.

[0082] In some embodiments, the cross-sectional shape of the fibers in the direction perpendicular to their length may be generally circular. In such embodiments, the diameter of each of the plurality of regenerated cellulose fibers 5 may be greater than 10 μm. Regenerated cellulose fibers of this size can help prevent fibers 5 from detaching from material 1 and reduce the risk of inhalation. In some embodiments where material 1 is used in articles having a fine filter material segment, said fine filter material segment is located downstream of a segment formed from material 1, and the diameter of at least some or each of the plurality of regenerated cellulose fibers 5 may be less than 10 μm.

[0083] In some embodiments, the cross-section of each of the plurality of regenerated cellulose fibers 5 may be a shape other than the usual circular shape, such as, but not limited to, a “Y” shape. Irregularly shaped fibers, such as “Y” shaped fibers, have the advantage that they have a larger surface area and are therefore able to provide better filtration and higher pressure drop. In such embodiments, the maximum dimension between points on the perimeter of the shape can be greater than 10 μm.

[0084] In some embodiments, the plurality of regenerated cellulose fibers 5 may have a fiber length to diameter ratio in the range of about (60 mm / 100 μm) 600:1 to about (30 mm / 10 μm) 3000:1.

[0085] In some embodiments, material 1 may be provided in the form of a sheet or an elongated body of material. Material 1 may have a content of 30 to 150 g / m². 2 30 to 120 g / m 2 Or 40 to 100 g / m 2 The material is in sheet form and its weight is constant. Sheet form materials can have a thickness of 60 to 500 µm or 150 to 350 µm.

[0086] In some embodiments, material 1 may be provided in the form of a nonwoven sheet formed of a plurality of regenerated cellulose fibers 5. The term “nonwoven” is used in the context of this application to refer to fibrous material, web, mat, or sheet in which a plurality of regenerated cellulose fibers are arranged in an undefined or random orientation.

[0087] To form material 1, multiple nonwoven regenerated cellulose fibers initially exist as unbonded fibers or threads. These multiple nonwoven regenerated cellulose fibers or threads can then be bonded together.

[0088] In this embodiment, a material 1 in the form of multiple nonwoven regenerated cellulose fibers 5 can be produced by hydrospinning multiple regenerated cellulose fibers 5. The multiple regenerated cellulose fibers 5 can be hydrospinned to produce a material 1 with the desired physical properties.

[0089] The present invention also provides a method for forming a material 1 suitable for use as a component 2 in an aerosol supply article 3. The method includes extruding a plurality of fibers comprising regenerated cellulose, hydroentangling the fibers to form a nonwoven sheet, and processing the nonwoven sheet to provide a material suitable for use as a component of an aerosol supply article. The advantage of nonwoven materials formed from hydroentangled fibers is their lower stiffness compared to other nonwoven materials. This results in materials that are easier to aggregate into rod-shaped components, and thus the resulting components exhibit fewer and smaller voids.

[0090] Material 1 comprising multiple nonwoven regenerated cellulose fibers 5 can be processed to provide material 1 suitable for component 2 of aerosol supply articles 3 (e.g., but not limited to filter components of consumable articles). For example, a nonwoven fiber web of material 1 formed from multiple regenerated cellulose fibers 5 can be passed through a sheet preforming unit and pleated to form a rod-shaped component comprising multiple pleats.

[0091] The rod-shaped component 2 can then be externally attached to packaging material to form a continuous rod, which can be used as component 2 in an aerosol supply article 3, such as a filter element. The width of the sheet-shaped material 1 can vary. Typically, the width of the material sheet 1 can be pleated to form the width of component 2.

[0092] The total width of the material plate 1 used to form component 2 can depend on several factors, such as the thickness of the material plate 1, the number of pleats required, the characteristics of the pleats produced, the surface characteristics of the material, i.e., fiber surface or smooth surface, the porosity of the material, the moisture content of the material, the lubrication properties of the material, the frictional characteristics of the mesh preforming device relative to the material plate 1, and other such factors.

[0093] In some embodiments, the nonwoven sheet of material 1 may have a width ranging from about 5 mm to about 200 mm. In some embodiments, the nonwoven sheet of material 1 may have a width ranging from about 50 mm to about 200 mm. In some embodiments, the nonwoven sheet of material 1 may have a width ranging from about 50 mm to about 120 mm. In some embodiments, the nonwoven sheet of material 1 may have a width ranging from about 60 mm to about 80 mm.

[0094] In some embodiments, the nonwoven sheet of material 1 may include at least one slit. In some embodiments, the nonwoven sheet of material 1 may include multiple slits. At least one slit may extend longitudinally through material 1. It is not intended to be theoretically correct, but it is thought that when material 1 is aggregated, the slit allows material 1 to align more consistently and uniformly within component 2, which improves pressure drop across component 2. The slits in the sheet of material 1 allow material 1 to expand or “bloom,” providing enhanced filtration performance.

[0095] In some embodiments, the nonwoven sheet of material 1 may undergo a curling step. Curling can be considered as a parameter referring to the texture or waviness of a single regenerated cellulose fiber 5, or as a parameter referring to the texture or waviness of the nonwoven sheet of material 1 as a whole. The amplitude or depth of a single curl can be measured in micrometers. The amplitude or depth of a single curl is an indirect measure of the degree of curl applied to the nonwoven sheet of material 1.

[0096] In some embodiments, curling the nonwoven sheet 1 may involve passing the nonwoven sheet 1 through one or more curling and / or embossing rollers configured to curl the nonwoven sheet 1, thereby providing a curled nonwoven sheet 1. Typically, the nonwoven sheet of material 1 is passed through curling and / or embossing rollers having a specific depth to obtain a desired curl amplitude or depth in the curled nonwoven sheet of material 1. That is, the curling and / or embossing rollers may include features having a specific amplitude or depth configured to achieve a desired curl amplitude or depth in the curled nonwoven sheet 1 of material.

[0097] In some embodiments, the crimping roller may be an electro-polished crimping roller. It has been found that electro-polished crimping rollers allow the material plate 1 to be crimped to a greater depth while causing less damage to the multiple regenerated cellulose fibers.

[0098] In some embodiments, the curl amplitude or curl depth can range from about 1 micrometer to about 1000 micrometers. The curl amplitude or curl depth can range from about 1 micrometer to about 800 micrometers. The inventors have found that a curl amplitude or curl depth of less than 800 micrometers may begin to result in a decrease in the obtained voltage drop. In some embodiments, the curl amplitude or curl depth can range from about 1 micrometer to about 600 micrometers. In some embodiments, the curl amplitude of the curl depth can range from about 1 micrometer to about 400 micrometers, or from about 1 micrometer to about 300 micrometers, or from about 1 micrometer to about 200 micrometers. In some embodiments, the curl amplitude or curl depth can range from about 1 micrometer to about 180 micrometers, or from about 1 micrometer to about 150 micrometers, or from about 75 micrometers to about 150 micrometers, or from about 50 micrometers to about 100 micrometers.

[0099] Alternatively, or in addition to the features and parameters described above, several other features may be used to characterize the nonwoven sheet of material 1 formed from a plurality of regenerated cellulose fibers 5. One of these characteristics is basis weight. In some embodiments, the basis weight of the nonwoven sheet of material 1 may be approximately 30 g / m². 2 Approximately 120 g / m 2 Within a certain range. In some embodiments, the basis weight of the nonwoven sheet of material 1 can be approximately 50 g / m². 2 Approximately 90 g / m2 Within a certain range. In some embodiments, the basis weight of the nonwoven sheet of material 1 can be approximately 30 g / m². 2 Approximately 50 g / m 2 or approximately 35 g / m 2 Approximately 45 g / m 2 The thickness of the nonwoven sheet of material 1 is within the range of approximately 0.01 mil (0.00025 mm) to approximately 4 mil (0.1 mm), or approximately 0.01 mil (0.00025 mm) to approximately 1 mil (0.025 mm), or approximately 0.01 mil (0.00025 mm) to approximately 0.5 mil (0.127 mm).

[0100] In some embodiments, the nonwoven sheet 1 formed from a plurality of regenerated cellulose fibers 5 may be thin and may have relatively high tensile strength, high resilience, and relatively good flexibility. In some embodiments, it may be desirable that the nonwoven sheet of material 1 remains folded without tearing, breaking, or otherwise fracturing during folding, rolling, or pleating processes.

[0101] In some embodiments, material 1 may have a content of 0.1 to 0.3 g / cm³. 3 Or 0.14 to 0.22 g / cm³ 3 The elongated body is a material with a high bulk density. In some embodiments, the elongated material body may include a plurality of fibers extending longitudinally from a first end of the body through the body to a second end. In some embodiments, the elongated material body may include rod-shaped elements having a circumference between about 16 mm and about 25 mm, or between about 18 mm and about 23 mm.

[0102] In some embodiments, material 1 may be provided as a regenerated cellulose tow. Material 1 may have any of the properties or characteristics discussed herein. For example, the regenerated cellulose tow material 1 may be formed from 3 dpf continuous fibers (also referred to as yarns). The regenerated cellulose tow material 1 may have a length of at least 1.5 km. The cross-section of the regenerated cellulose fibers forming the regenerated cellulose tow material 1 may be “Y” shaped. In some embodiments, the regenerated cellulose tow material 1 may be titanium dioxide-free. The regenerated cellulose tow material 1 may also contain halogen-free spinning oil.

[0103] In some embodiments, the regenerated cellulose tow material 1 may have a total denier of at least 12,000. In some embodiments, the regenerated cellulose tow material 1 may have a total denier of at least 20,000. In some embodiments, the regenerated cellulose tow material 1 may have a total denier of at least 25,000. In some embodiments, the regenerated cellulose tow material 1 may have a total denier of at least 30,000. In some embodiments, the regenerated cellulose tow material 1 may have a total denier of at least 35,000. That is, the mass of the regenerated cellulose tow material 1 may be at least 35,000 grams per 9,000 meters of regenerated cellulose tow. In some embodiments, the regenerated cellulose tow material 1 may have a total denier of less than or equal to 80,000. In some embodiments, the regenerated cellulose tow material 1 may be provided in bundles.

[0104] In some embodiments, additives may be applied to the nonwoven sheet of Material 1 before, during, or after its formation. In some embodiments, additives may be added to the pleated nonwoven sheet of Material 1 during component formation to provide desired sensory characteristics and / or improve aerosol chemistry. In some embodiments, the additive may include glyceryl triacetate and / or carbowax, which may be applied to the nonwoven sheet of Material 1 in conventional amounts using known techniques. The additive may be a plasticizer.

[0105] In some embodiments, the additive may be applied to the nonwoven sheet of Material 1 in an amount of about 0.1% to about 20% by weight, based on the total weight of the nonwoven sheet of Material 1. In some embodiments, the additive may be applied to the nonwoven sheet of Material 1 in an amount of about 3% to about 15% by weight, or about 6% to about 12% by weight. For example, the additive may be applied to the nonwoven sheet of Material 1 in an amount of at least about 2 wt%, at least about 4 wt%, at least about 6 wt%, at least about 8 wt%, at least about 10 wt%, at least about 12 wt%, at least about 14 wt%, at least about 16 wt%, or at least about 18 wt% based on the total weight of the nonwoven web of Material 1.

[0106] Brief Reference Figure 2 The diagram shows a component 2 formed from the material 1 of the present invention. As previously described, the component 2, formed from a nonwoven sheet of material 1 composed of a plurality of regenerated cellulose fibers 5, can be a filter component. Therefore, material 1 can be considered a filter material, even if it is not used in the aerosol supply article 3. The aerosol supply article 3 comprising the component 2 formed from material 1 can be manufactured using conventional methods and techniques, wherein the material 1 comprises a plurality of nonwoven regenerated cellulose fibers 5.

[0107] Brief Reference Figure 3 The diagram illustrates an aerosol supply article 3 comprising a component 2 formed from material 1 of the present invention. The dimensions of a representative aerosol supply article 3 according to the present invention can vary. In some embodiments, the aerosol supply article 3 may be rod-shaped. The aerosol supply article 3 may have a diameter of about 7.5 mm and a circumference of about 23.5 mm. In some embodiments, the aerosol supply article 3 may have a diameter ranging from about 3.1 mm to about 11.2 mm and a circumference ranging from about 10 mm to about 35 mm. In some embodiments, the aerosol supply article 3 may have a diameter ranging from about 5 mm to about 7.7 mm and a circumference ranging from about 16 mm to about 24 mm.

[0108] In some embodiments, the aerosol supply article 3 may have an overall length ranging from about 60 mm to about 150 mm. In some embodiments, the aerosol supply article 3 may have an overall length ranging from about 80 mm to about 144 mm. However, the length of the aerosol supply article 3 may vary. In some embodiments, for example, the aerosol supply article 3 may have an overall length of about 140 mm or less, about 100 mm or less, about 80 mm or less, about 60 mm or less, or about 40 mm or less. The length of the component 2 formed from material 1 may also vary. When the component 2 formed from material 1 is a filter component, the component 2 may have an overall length ranging from about 15 mm to about 40 mm, typically from about 20 mm to about 35 mm.

[0109] Contains Figure 2 and 3 The component 2, formed from the material 1 of the plurality of regenerated cellulose fibers 5 shown, can exhibit the desired suction resistance. That is, when gas is drawn from one side to the other, the component 2 can exhibit a desired pressure drop along its length. In some embodiments, the pressure drop can be in the range of about 40 mmWG to about 650 mmWG. In some embodiments, the pressure drop can be in the range of about 100 mmWG to about 350 mmWG, about 150 mmWG to about 325 mmWG, or about 200 mmWG to about 300 mmWG, or about 250 mmWG to about 200 mmWG.

[0110] Alternatively, the pressure drop of component 2 can be measured in mm / WG / mm in the longitudinal direction of component 2. Component 2 can be a standard perimeter component, i.e., about 23 mm to about 25 mm. The pressure drop can be about 1 mm / WG / mm in length to about 6.5 mm / WG / mm in length of component 2. In some embodiments, the pressure drop can be in the range of about 2 mm / WG / mm in length of component 2 to about 4.5 mm / WG / mm in length of component 2. In some embodiments, the pressure drop can be in the range of about 4.5 mm / WG / mm in length of component 2 to about 6.5 mm / WG / mm in length of component 2.

[0111] Furthermore, the component 2 formed from the material 1 comprising a plurality of regenerated cellulose fibers 5 can exhibit a desired hardness. In some embodiments, the component 2 can have a hardness in the range of about 70% to about 99%. In some embodiments, the component 2 of the present invention can exhibit a hardness of about 75% or higher, about 80% or higher, about 85% or higher, or about 90% or higher. In some embodiments, the hardness of the component 2 can be in the range of about 85% to about 93%. In some embodiments, the component may include filter rod forming paper or other packaging material surrounding the material 1 having a basis weight of 60 gsm or higher. The component being surrounded by packaging material having a basis weight of 60 gsm or higher helps to increase the hardness of the component.

[0112] The hardness of this component can be measured according to the following procedure. When referring to the hardness of a section, the hardness is the hardness determined as follows. Any suitable apparatus can be used to perform the measurement, such as the Borgwaldt H10 hardness tester.

[0113] Hardness is defined as the ratio between the height h0 and the height h1 of a body under a defined load, expressed as a percentage of h0. Hardness can be expressed as: Hardness = (h1 / h0) × 100 For a single body or a body contained in multiple bars, perform a hardness measurement at the longitudinal center point of the body or multiple bars (as specified).

[0114] A load bar is used to apply a defined load to the body. The length of the load bar should be significantly longer than the length of the sample to be tested. Before hardness measurement, the body to be measured should be conditioned for at least 48 hours according to ISO 3402:2023 and maintained under ambient conditions according to ISO 3402:2023 during the measurement.

[0115] To perform hardness measurement, the sample was placed in a hardness tester H10, and a preload of 2g was applied. After 1 second, the initial height h0 of the sample under the 2g preload was recorded. The preload was then removed, and a load bar bearing a 150g load was lowered onto the sample at a rate of 0.6 mm / s. After 5 seconds, the height h1 of the sample under the 150g load was measured.

[0116] The hardness of the component was determined as the average hardness of at least 20 components measured according to the scheme.

[0117] For reference, embodiments of component 2 described below are given by way of example only. Reference is made to component 2 in the following embodiments for a given length of base rod. This base rod component can be cut into smaller segments and used in or as a filter in a product.

[0118] In one example, component 2 can be formed from a sheet of spunlace nonwoven material. Component 2 can be formed from a sheet of material 1 comprising a plurality of regenerated cellulose fibers having a dpf of about 3. The regenerated cellulose fibers 5 can be formed from lyocell. Component 2 can be formed from a sheet of material 1 with a weight in the range of 50 to 60 gsm.

The component can have a length of about 80 mm and a circumference of about 20 mm to about 21 mm. Component 2 can have a weight in the range of about 0.39 g to about 0.47 g. The component can have a weight in the range of about 0.42 g to about 0.45 g. The pressure drop across component 2 can be in the range of about 150 mmWG to about 240 mmWG. The pressure drop across the component can be in the range of about 170 mmWG to about 210 mmWG. The component can have a hardness in the range greater than 80%. Component 2 can be wrapped with filter rod forming paper weighing 60 gsm.

[0121] The described base rod component can be cut into 8 segments, such that each segment in the filter portion of the article, or used as a filter portion of the article, is approximately 10 mm long. Therefore, the parameters given above can be divided by 8 to obtain the parameters for a single-segment component. The pressure drop across the 10 mm segment 2 can be in the range of approximately 42 mmWG to approximately 55 mmWG.

[0122] In one example, component 2 can be formed from a spunlace nonwoven material sheet 1. Component 2 can be formed from a sheet of material 1 containing a plurality of regenerated cellulose fibers 5 having a dpf (dpf) in the range of 2.5 to 3. The regenerated cellulose fibers 5 can be formed from lyocell. Component 2 can be formed from a sheet of material 1 containing a plurality of 3 dpf regenerated cellulose fibers. Component 2 can be formed from a sheet of material 1 having a weight of 60 gsm. Component 2 can be formed from a material sheet 1 having a width of approximately 130 mm.

[0123] Component 2 can have a length in the range of about 105 mm to 110 mm. The component can have a length of about 108 mm. Component 2 can have a weight in the range of about 0.94 g to about 1.05 g. The component can have a weight in the range of about 0.98 g to about 1.02 g. The circumference of component 2 can be about 24 mm. The pressure drop on component 2 can be in the range of about 250 mmWG to about 310 mmWG. The pressure drop on component 2 can be in the range of about 265 mmWG to about 295 mmWG. Component 2 can have a hardness in the range of about 86% to about 93%. Component 2 can have a hardness in the range of about 88% to about 92%. Component 2 can be cut into 4 segments, each about 27 mm long, which can be used in the filter portion of the article or used as the filter portion of the article. Thus, the parameters given above can be divided by 4 to achieve the parameters of a single segmented component.

[0124] Now for reference Figure 4An exploded view of an exemplary aerosol supply article 10 is shown. The exemplary aerosol supply article 10 is shown as generally cylindrical. However, it should be understood that in other embodiments, the aerosol supply article 10 may be, for example, but not limited to, cubic and optionally substantially planar.

[0125] The aerosol supply article 10 includes a generally cylindrical rod 12. The generally cylindrical rod 12 includes aerosol generating material 13. The aerosol generating material 13 can be provided as a charge or roll of aerosol generating material 13. The aerosol generating material 13 can be, for example, but not limited to, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco substitutes, or other smokeable materials, non-tobacco materials, or amorphous solid materials.

[0126] The rod 12 of the aerosol generating material 13 may be contained within an external packaging material 14. The ends of the rod 12 may be open to expose the aerosol generating material 13.

[0127] A distal end 18 is positioned at one end of the rod 12 of the aerosol generating material 13. If the aerosol supply article 10 is a combustible aerosol supply article, the distal end 18 may be the end of the aerosol supply article 10 that is ignited during use. If the aerosol supply article 10 is a non-combustible aerosol supply article, the distal end 18 may be the end of the aerosol supply article 10 that is first inserted into the aerosol supply device (not shown).

[0128] A proximal end 19 is positioned at the other end of the rod 12 of the aerosol generating material 13. The proximal end 19 of the rod 12 may be the end of the rod 12 that is closer to the consumer's mouth during use. In this embodiment, the filter element 22 is positioned adjacent to the proximal end 19 of the rod 12. The filter element 22 may include a component 2 formed of a material 1 comprising a plurality of nonwoven regenerated cellulose fibers 5 as described herein.

[0129] The filter element 22 may have a generally cylindrical shape. The diameter of the filter element 22 may be substantially equal to the diameter of the rod 12 of the aerosol generating material 13. The filter element 22 may be surrounded by an outer filter rod forming paper 24 along its outer perimeter or longitudinal perimeter to form the filter element 22. The filter element 22 may be positioned adjacent to one end of the rod 12 of the aerosol generating material 13, i.e., the proximal end 19, such that the filter element 22 and the rod 12 of the aerosol generating material 13 are axially aligned. The rod 12 of the aerosol generating material 13 and the filter element 22 may be axially aligned end-to-end. In some embodiments, the rod 12 of the aerosol generating material 13 and the filter element 22 may be axially aligned end-to-end abutment. The end of the filter element 22 may allow air and aerosol to pass through it.

[0130] The aerosol supply article 10 may also include a tipping wrapper 25. The tipping wrapper 25 may be externally attached to at least a portion of the outer perimeter of the outer filter rod forming paper 24 of the filter element 22 and at least a portion of the packaging material 14 of the rod 12 of the aerosol generating material 13. Thus, the tipping wrapper 25 may be configured to attach the filter element 22 to the rod 12 of the aerosol generating material 13.

[0131] The tipping material 25 may be airtight. In some embodiments, the tipping material 25 may be external to both the entire length of the filter element 22 and the adjacent area of ​​the rod 12 of the aerosol generating material 13. The inner surface of the tipping material 25 may be securely attached to the outer surface of the filter rod forming paper 24 and the outer surface of the packaging material 14 of the rod 12 of the aerosol generating material 13. A suitable adhesive may be used to securely attach the tipping material 25 to the filter rod forming paper 24 and the packaging material 14. Thus, the filter element 22 and the rod 12 of the aerosol generating material 13 may be connected to each other to form the aerosol supply article 10.

[0132] In some implementations, such as Figure 4 In the illustrated embodiment, the aerosol supply article 10 can be a ventilated or air-diluted smoking article 10. Therefore, the aerosol supply article 10 may include an air dilution device 26. The air dilution device 26 may be, for example, but not limited to, a series of perforations 27. Each perforation 27 may extend through the tipping material 25 and the packaging material 14. The series of perforations 27 can be made using various techniques known in the art, such as laser perforation. Alternatively, offline air dilution techniques may be used, for example, but not limited to, using porous filter rod forming paper and / or pre-perforated tipping material.

[0133] For the breathable aerosol supply article 10, the amount or extent of air dilution or ventilation can vary. For example, in some embodiments, the amount of air dilution or ventilation of the aerosol supply article 10 can be greater than about 10%. In some embodiments, the amount of air dilution or ventilation of the aerosol supply article 10 can be greater than about 20%, sometimes greater than 30%, and sometimes greater than 40%. Typically, the upper level of air dilution for the aerosol supply article 10 can be less than 80%, and typically less than about 70%. As used herein, the term "air dilution" is the ratio of the volume of air drawn in through the air dilution device 26 to the total volume of air and aerosol drawn in through the aerosol supply article 10 and exiting the extreme nozzle portion of the aerosol supply article 10.

[0134] The filter element 22 may include a mouthpiece 29. The mouthpiece 29 may be the end of the aerosol supply article 10. The mouthpiece 29 may be configured to be placed in the user's mouth for the user to inhale during use.

[0135] It should be understood that the foregoing and description of the aerosol supply article 10 are not intended to limit the invention. In particular, the materials 1 and components 2 of the present invention can be incorporated into a variety of different aerosol supply articles 10, including but not limited to conventional cigarettes, heated tobacco products, tobacco heating products, electronic cigarette products, aerosol delivery devices, etc., as well as aerosol supply articles that may include features from each of the previously mentioned categories of aerosol supply articles.

[0136] In some embodiments, the aerosol delivery articles and / or aerosol delivery systems of the present invention can provide many of the sensations of conventional cigarettes without any substantial degree of combustion of any of its components. The sensations provided may include inhalation and exhalation rituals, type of taste or aroma, sensory effects, physical sensations, rituals of use, visual cues (such as those provided by visible aerosols), etc. For example, users of some embodiments of the aerosol delivery articles and / or aerosol delivery systems of this invention can hold and use the component in a manner similar to that of a smoker using a conventional cigarette. That is, the user can hold the component and inhale at one end of the component to inhale the aerosol produced by the component, and then inhale or inhale once at selected time intervals.

[0137] Now for reference Figure 5 An exemplary aerosol delivery device 30 is shown. The exemplary aerosol supply device 30 may include a body 32. The body 32 may be configured to receive aerosol supply articles 3, 10, as previously described. Various mechanisms may be used to connect the aerosol supply articles 3, 10 to the body 32 of the aerosol supply device 30. Such mechanisms may include, but are not limited to, threaded engagement, press-fit engagement, interference fit, sliding fit, magnetic engagement, etc.

[0138] In various embodiments, the aerosol supply device 30 can have a variety of overall shapes, including, for example, but not limited to, an overall shape that can be defined as generally rod-shaped, generally tubular, or generally cylindrical, such as... Figure 5 As shown in the image. That is, Figure 5 The aerosol supply device 30 shown has a substantially circular cross-section. However, it should be understood that in alternative embodiments, the body 32 of the aerosol supply device 30 may have different cross-sections, such as, but not limited to, a substantially rectangular shape, such as a substantially rectangular-cubic shape. In some embodiments, the body 32 of the aerosol supply device 30 or any other component thereof may have other handheld shapes. For example, the aerosol supply device 30 may have a box shape, various PD model shapes, or a keychain shape.

[0139] The alignment of the aerosol supply article 10 within the aerosol supply device 30 can be varied. In some embodiments, the substrate portion can be positioned near a heat source to maximize aerosol delivery to the user. Typically, the heat source can be positioned sufficiently close to the rod 12 of the aerosol generating material 13 such that heat from the heat source causes the aerosol generating material 13 and any other substances present (such as one or more flavorings, active ingredients, etc.) to volatilize and form an aerosol for delivery to the user. When the heat source heats the substrate portion, the aerosol is formed, released, or generated in a physical form suitable for inhalation by the consumer.

[0140] The aerosol supply device 30 may include a battery and / or other power source to provide sufficient current to power various functions of the aerosol delivery device, such as powering a heat source, a control system, an indicator, etc., as described in more detail below. In some embodiments, the power source is capable of delivering sufficient power to rapidly activate the heat source to provide aerosol formation and to power the aerosol supply device 30 for a sustained desired duration. In some embodiments, the power source may be designed to be conveniently housed within the body 32 of the aerosol supply device 30, allowing the aerosol supply device 30 to be easily held. The power source may be a replaceable or rechargeable battery, a solid-state battery, a thin-film solid-state battery, or a rechargeable supercapacitor, etc., and may be combined with any suitable type of recharging technology.

[0141] The aerosol supply article 10 may include a heating section 16. The heating section 16 may typically be a segment of the aerosol supply article 20, which includes a rod 12 of the aerosol generating material 13 or at least a portion thereof. The heating section 16 may be configured to be inserted into the body 32 of the aerosol supply device 30.

[0142] The material 1 of the present invention has been tested to evaluate the various properties of the component 2 formed from the material 1 comprising a plurality of nonwoven regenerated cellulose fibers 5.

[0143] In one aspect of the invention, as follows is provided Figure 1 Material 1 shown is used as follows: Figure 2 The aerosol shown provides a component in article 3. Material 1 comprises multiple fibers 5 containing regenerated cellulose and an adhesive. The material has a density of approximately 0.1 g / cm³. 3 To approximately 0.4 g / cm 3 The volume density within the specified range.

[0144] The plurality of fibers 5 may be discontinuous. The plurality of fibers may have a fiber length ranging from about 10 mm to about 60 mm. The plurality of fibers may be wet-woven. In some embodiments, the plurality of fibers may be air-laid. An adhesive 6 may be configured to bond the plurality of fibers 5 together. The plurality of regenerated cellulose fibers 5 have a density of about 0.12 g / cm³. 3 To approximately 0.3 g / cm 3 The bulk density of the multiple regenerated cellulose fibers is approximately 0.15 g / cm³. 3 To approximately 0.25 g / cm 3 The bulk density. The denier of the single filaments of the plurality of regenerated cellulose fibers 5 can be about 1 dpf and about 10 dpf.

[0145] The material 1 and the component 2 formed from the present aspect of the invention are similar to the component 2 of the previously described aspects, and therefore their detailed description will be omitted here. Furthermore, similar features and components will retain their terms and reference numerals. It should also be understood that the features and components of the aforementioned material 1 and component 2 can be incorporated into the material 1 and component 2 of this aspect, and vice versa.

[0146] The nonwoven sheet of Material 1 can be produced by conventional forming methods such as wet weaving. It is known in industry that the term wet weaving has a broad meaning and can be combined with various equipment, methods, and means. The use of the term wet weaving is not restrictive and does not limit the use of a single method for manufacturing.

[0147] Multiple fibers 5 can be wet-woven. As used herein, the term "wet-woven" generally refers to a method of producing a fibrous sheet of material 1 by means similar to papermaking, wherein the fibers are suspended in an aqueous medium, and the sheet is formed by filtering the suspension on a conveyor belt or perforated roller. Adhesives can be introduced to achieve desired final properties in the wet-laid nonwoven sheet of material 1.

[0148] In some embodiments, the binder 6 may be, for example, but not limited to, polyvinyl alcohol (PVOH), pectin, starch, microfibrillated cellulose (MFC), polysaccharides, shellac, and combinations thereof. In some embodiments, the binder 6 may be an alternative natural polymer not mentioned in the foregoing list.

[0149] When material 1 is formed into part 2 or article 3, the bulk density of the plurality of fibers 5 of regenerated cellulose can be calculated without considering any other characteristics of material 1, part 2 or article 3.

[0150] As described above, the multiple fibers 5 of the regenerated cellulose material can have a density of approximately 0.10 g / cm³. 3To approximately 0.40 g / cm 3 The bulk density is within the range specified. In some embodiments, the plurality of fibers 5 of the regenerated cellulose material may have a bulk density of about 0.12 g / cm³. 3 To approximately 0.30 g / cm 3 The bulk density is within the range of [specific parameters]. In some embodiments, the plurality of fibers 5 of the regenerated cellulose material may have a bulk density of approximately 0.15 g / cm³. 3 To approximately 0.25 g / cm 3 The volume density within the specified range.

[0151] The bulk density of material 1 can be customized to provide a satisfactory pressure drop for the user when the material is formed into part 2 for use in article 3 or in article 3. In addition, the reduction in the bulk density of material 1 improves cost efficiency and material use, and thus reduces the manufacturing impact on the environment.

[0152] It should be understood that although the plurality of fibers 5 have been previously described as containing regenerated cellulose, the plurality of fibers 5 forming material 1 may be composed of or substantially composed of regenerated cellulose.

[0153] In some embodiments, material 1 may include one or more coatings, fillers, additives, and / or other components. In some embodiments, material 1 may include multiple fibers and one or more coatings, fillers, additives, surface treatments, or other materials applied thereto or incorporated therein. One such coating may be, for example, a plasticizer, such as glyceryl triacetate, which is typically applied to conventional filter materials in conventional amounts using known techniques.

[0154] In some embodiments, other materials applied to or incorporated into material 1 may be applied in liquid form. These other materials may include, for example, but not limited to, triacetin, carbon waxes, flavoring compounds, propylene glycol, triethyl citrate, or any other suitable substance. Furthermore, each coating, filler, or other component applied to material 1 may contribute some functionality or property to the component 2 formed from material 1. For example, each coating, filler, or other component may contribute to filtering aerosols, improving aerosol flavor, water dispersibility, biodegradability, and / or compostability.

[0155] In some embodiments, adhesive 6 may be applied to the nonwoven sheet of material 1 before, during, or after its formation. In some embodiments, adhesive may be added to the pleated nonwoven sheet of material 1 during part formation to provide desired sensory characteristics and / or improve aerosol chemistry. The adhesive (which may contain pectin in some embodiments) may be applied to the nonwoven sheet of material 1 in conventional amounts using known techniques.

[0156] In some embodiments, the adhesive may be applied to the nonwoven sheet of Material 1 in an amount from about 0.1 wt% to about 30 wt%, based on the total weight of the nonwoven sheet of Material 1. In some embodiments, the adhesive may be applied to the nonwoven sheet of Material 1 in an amount from about 5% to about 30% by weight. The adhesive may be, for example, pectin or starch. The amount of adhesive may be determined based on the dpf of the fiber and the weight of the sheet of Material 1. It has been determined that too much adhesive makes the material too stiff and difficult to operate on manufacturing equipment.

[0157] In some embodiments, the adhesive may be applied to the nonwoven sheet 1 of material 1 in an amount of about 3% to about 15% by weight, or about 6% to about 12% by weight. For example, the adhesive may be applied to the nonwoven sheet 1 of material 1 in an amount of at least about 2 wt%, at least about 4 wt%, at least about 6 wt%, at least about 8 wt%, at least about 10 wt%, at least about 12 wt%, at least about 14 wt%, at least about 16 wt%, or at least about 18 wt% based on the total weight of the nonwoven sheet of material 1.

[0158] In some embodiments, the adhesive comprises 2 wt% to 20 wt% of component 2 used for aerosol supply article 2. In some embodiments, the adhesive may be applied to the nonwoven sheet of material 1 in an amount of 4 wt%. Advantageously, it has been found that the adhesive is applied to the nonwoven web of material 1 in an amount of about 4 wt%. The adhesive may contain pectin. The adhesive may contain about 4 wt% of component 52 of pectin.

[0159] In one aspect of the invention, a component 2 for an aerosol supply article 3 is provided. The component 2 comprises an aerosol generating material 1, which comprises a plurality of fibers 5 formed from regenerated cellulose. The aerosol generating material 1 of the component 2 further comprises an aerosol forming agent material in the range of about 5 wt% to about 60 wt% of the aerosol generating material 1.

[0160] Component 2 of the present aspect of the invention is similar to component 2 of the previously described aspect, and therefore its detailed description will be omitted here. Furthermore, similar features and components will retain their terms and reference numerals. It should also be understood that features and components of the aforementioned component 2 can be incorporated into component 2 of this aspect, and vice versa.

[0161] Aerosol forming agent materials may include one or more components capable of forming aerosols. In some embodiments, the aerosol forming agent material may include one or more of glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butanediol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl caprylate, triethyl citrate, triacetin, a mixture of diacetic acids, benzyl benzoate, benzyl acetate, phenyl acetate, glyceryl tartrate, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. In some embodiments, the aerosol forming agent material includes one or more polyols, such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols, such as mono-, di-, or triacetic acids of glycerol; and / or aliphatic esters of monocarboxylic acids, dicarboxylic acids, or polycarboxylic acids, such as dimethyl dodecanoate and dimethyl tetradecanoate. Not wanting to be bound by theory, it is believed that including triacetin in this component promotes better nicotine delivery from component 2 to the user during use.

[0162] Aerosol forming agent materials may contain acids. It is not desirable to be bound by theory, but it is believed that the inclusion of acids reduces the perceived roughness of the generated aerosols.

[0163] Material 1 may comprise an aerosol forming agent. In some embodiments, the aerosol forming agent of Material 1 may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol may be present in an amount of 10% to 20% by weight of Material 1, for example 13% to 16% by weight of the composition, or about 14% or 15% by weight of the composition. Propylene glycol, if present, may be present in an amount of 0.1% to 0.3% by weight of the composition.

[0164] Aerosol forming material may be included in any component 2 formed of material 1 comprising a plurality of regenerated cellulose fibers 5, such as any filter component and / or any plug component, and / or any aerosol generating section (if present) that may be configured to be heated. In either case, the total amount of aerosol forming material in material 1 may be as defined herein.

[0165] In one example, the aerosol forming agent material may comprise an amorphous solid material containing 40% menthol, 16% glycerol, 20% binder (alginate / pectin mixture), and 20% fiber (wood pulp).

[0166] In some embodiments, the amorphous solid comprises: 1 wt%-60 wt% of a gelling agent; 0.1-50 wt% of an aerosol forming agent; and 0.1-80 wt% of a flavoring agent; wherein these weights are calculated based on dry weight.

[0167] In some other embodiments, the amorphous solids are designated as: 1 wt%-50 wt% gelling agent; 0.1-50 wt% aerosol forming agent; and 30-60 wt% flavoring agent; wherein these weights are calculated based on dry weight.

[0168] In some embodiments, the aerosol forming agent material may form 60% by weight of the material. For example, a component formed from lyocell and configured to be heated may include up to about 60% by weight of propylene glycerol, or vegetable glycerol, or a combination of propylene glycerol and vegetable glycerol.

[0169] In some embodiments, the component may include nicotine. The component may contain nicotine neutralized by benzoic acid at a 1:1 ratio, up to 5%. In some embodiments, a combination of levulinic acid and benzoic acid may be used.

[0170] In some further embodiments, the amorphous solid comprises: an aerosol forming agent material in an amount of about 40-80 wt% of the amorphous solid; a gelling agent and optional filler (i.e., in some instances, the filler is present in the amorphous solid, and in other instances, the filler is not present in the amorphous solid), wherein the amount of the gelling agent and filler together is about 10 wt% to 60 wt% of the amorphous solid (i.e., the amorphous solid). The gelling agent and filler together account for about 10 wt% to 60 wt% of the amorphous solid); and optionally, an active substance and / or flavoring agent in an amount of up to about 20 wt% of the amorphous solid (i.e., the amorphous solid). The amorphous solid contains ≤20 wt% of the active substance.

[0171] Amorphous solid materials can be formed from dried gels. It has been found that using the component ratios discussed above means that flavor compounds are stable within the gel matrix as the gel solidifies, allowing for higher flavor loadings than in non-gel compositions. Flavoring agents (e.g., menthol) are stable at high concentrations, and the product has a good shelf life.

[0172] In some cases, the amorphous solid may have a thickness of about 0.015 mm to about 1.5 mm. Suitably, the thickness may be in the range of about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm, 0.3 mm, or 1 mm. In some embodiments, a material with a thickness of 0.2 mm is particularly suitable. The amorphous solid may comprise more than one layer, and the thickness described herein refers to the aggregate thickness of those layers.

[0173] If the amorphous solid is too thick, heating efficiency is compromised. This adversely affects power consumption during use. Conversely, if the amorphous solid is too thin, it becomes difficult to manufacture and handle; very thin materials are more difficult to cast and may be brittle, thus impairing aerosol formation during use.

[0174] Suitably, the amorphous solids may comprise about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, 25 wt%, 30 wt%, or 35 wt% to about 60 wt%, 55 wt%, 50 wt%, 45 wt%, 40 wt%, or 35 wt% of a gelling agent (all based on dry weight). For example, the amorphous solids may comprise 1-60 wt%, 5-60 wt%, 20-60 wt%, 25-55 wt%, 30-50 wt%, 35-45 wt%, 5-45 wt%, 10-40 wt%, or 20-35 wt% of a gelling agent.

[0175] The amorphous solid may include a gelling agent. The gelling agent may include one or more compounds selected from cellulose gelling agents, non-cellulose gelling agents, guar gum, gum arabic, and mixtures thereof.

[0176] In some embodiments, the gelling agent comprises a hydrocolloid. In some embodiments, the gelling agent comprises one or more compounds selected from the group consisting of alginate, pectin, starch (and derivatives), cellulose (and derivatives), gum, silica or siloxane compounds, clay, polyvinyl alcohol, and combinations thereof. For example, in some embodiments, the gelling agent comprises one or more of alginate, pectin, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, gum arabic, fumed silica, polydimethylsiloxane (PDMS), sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the gelling agent comprises alginate and / or pectin and may be combined with a hardening agent (such as a calcium source) during the formation of the amorphous solid. In some cases, the amorphous solid may comprise calcium-crosslinked alginate and / or calcium-crosslinked pectin.

[0177] The cellulose gelling agent can be selected from the group consisting of: hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose (CMC), hydroxypropyl methyl cellulose (HPMC), methyl cellulose, ethyl cellulose, cellulose acetate butyrate (CAB), cellulose acetate propionate (CAP), and combinations thereof.

[0178] In some embodiments, the gelling agent comprises one or more of hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose (HPMC), carboxymethyl cellulose, guar gum, or gum arabic.

[0179] In some embodiments, the gelling agent includes / or one or more non-cellulose gelling agents, including but not limited to agar, xanthan gum, gum arabic, guar gum, pectin, carrageenan, starch, alginate, and combinations thereof. In a preferred embodiment, the non-cellulose-based gelling agent is alginate or agar.

[0180] In some embodiments, the amorphous solid comprises alginate and pectin, and the ratio of alginate to pectin is from 1:1 to 10:1. The ratio of alginate to pectin is typically greater than 1:1, meaning that the amount of alginate present is greater than the amount of pectin. In examples, the ratio of alginate to pectin is about 2:1 to 8:1, or about 3:1 to 6:1, or about 4:1.

[0181] In some embodiments, the amorphous solid contains filler in an amount of 1 to 30 wt%, for example 5 to 25 wt%, or 10 to 20 wt%, of the amorphous solid. In examples, the amorphous solid contains filler in an amount greater than 1 wt%, 5 wt%, or 8 wt% of the amorphous solid. In examples, the amorphous solid contains filler in an amount less than 4 wt%, 30 wt%, 20 wt%, 15 wt%, 12 wt%, 10 wt%, 5 wt%, or 1 wt% of the shaped solid. In other embodiments, the amorphous solid does not contain filler.

[0182] In one example, the amorphous solid comprises a gelling agent and filler, in total amounts from about 10 wt%, 20 wt%, 25 wt%, 30 wt%, 35 wt%, 40 wt%, 45 wt%, 50 wt%, 55 wt%, or from about 60 wt%. In another example, the amount of gelling agent and filler together is no more than 85 wt%, 80 wt%, 75 wt%, 70 wt%, 65 wt%, or no more than 60 wt% of the amorphous solid. In yet another example, the amorphous solid comprises a gelling agent and filler, in total amounts from about 20 wt% to 60 wt%, 25 wt% to 55 wt%, 30 wt% to 50 wt%, or 35 wt% to 45 wt% of the amorphous solid.

[0183] The packing material (if present) may include one or more inorganic packing materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic adsorbents, such as molecular sieves. The packing material may also include one or more organic packing materials, such as wood pulp, cellulose, and cellulose derivatives. In certain cases, the amorphous solid may not contain calcium carbonate, for example, chalk.

[0184] In some instances where fillers are included, the fillers can be fibrous. For example, the fillers can be fibrous organic fillers, such as wood pulp, hemp fiber, cellulose, or cellulose derivatives. It is not desirable to be bound by theory, but it is believed that including fibrous fillers in amorphous solids can increase the tensile strength of the material.

[0185] In some instances, amorphous solids do not contain tobacco fibers. In certain instances, amorphous solids do not include fibrous materials.

[0186] In some embodiments, the amorphous solids may include about 0.1 wt%, 0.5 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, or 10 wt% to about 80 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, 30 wt%, or 2 wt% of aerosol forming agent material (all based on dry weight). For example, the amorphous solids may contain 0.5-40 wt%, 3-35 wt%, or 10-25 wt% of aerosol forming agent material.

[0187] Aerosol forming agents can be used as plasticizers. If the plasticizer content is too high, the amorphous solids may absorb water, resulting in an unsuitable consumption experience during material use. If the plasticizer content is too low, the amorphous solids may be brittle and prone to breakage.

[0188] In some embodiments, the aerosol forming agent contained in the amorphous solid comprises one or more polyols, such as propylene glycol, triethylene glycol, 1,3-butanediol and glycerol; esters of polyols, such as mono-, di- or triacetic acid esters of glycerol; and / or aliphatic esters of monocarboxylic acids, dicarboxylic acids or polycarboxylic acids, such as dimethyl dodecanoate and dimethyl tetradecanoate.

[0189] In some cases, aerosol-forming materials include one or more compounds selected from erythritol, propylene glycol, glycerol, triacetyl, sorbitol, and xylitol. Including triacetylglycerol can reduce the perceived roughness of the generated aerosol. In some cases, aerosol-forming materials contain glycerol, are substantially composed of glycerol, or are composed of glycerol.

[0190] Amorphous solid materials may include a flame-retardant salt. The flame-retardant salt used herein is a compound composed of ionic components of cationic and anionic groups. The salts used herein are those whose anionic and / or cationic components can effectively delay combustion. In some embodiments, the salt is an inorganic salt.

[0191] In some embodiments, the salt is a halide salt, i.e., having a halide anion. In some embodiments, the salt is a chloride salt or a bromide salt. The presence of high concentrations of chloride or bromide has been shown to delay combustion.

[0192] In some embodiments, the salt may be an alkali metal salt, i.e., having an alkali metal cation. In some embodiments, the salt has an alkaline earth metal cation. In some embodiments, the salt has a zinc cation or an iron cation, such as an iron or ferrous cation. In some embodiments, the salt has an ammonium cation or a phosphonium cation.

[0193] In some embodiments, the salt is an alkali metal halide, such as sodium chloride or potassium chloride. The salt can also be an alkaline earth metal halide, such as magnesium chloride or calcium chloride. Alternatively, the salt can be another metal halide, such as zinc chloride or sodium bromide.

[0194] In some embodiments, the salt has a carboxylic acid anion. For example, the salt can be an alkali metal carboxylate, such as potassium citrate, potassium succinate, potassium malate, potassium acetate, potassium tartrate, potassium oxalate, sodium citrate, sodium succinate, sodium acetate, or sodium malate.

[0195] In other embodiments, the salt has anion selected from the following: borate, carbonate, phosphate, sulfate, or aminosulfonate.

[0196] Factors influencing salt selection include, for example, melting point, which is preferably at least 450°C. In some embodiments, the salt is soluble in water. In some embodiments, the salt is selected to provide a desired pH to the material to which it is added. In some embodiments, the salt does not significantly alter the pH of the material.

[0197] In some embodiments, the selected flame-retardant salt may have one or more advantageous properties, such as inertness, solubility in the precursor liquid, solubility, or distribution in the amorphous solid material or precursor material relative to the amorphous solid material, density, or other properties known in the art.

[0198] In some embodiments, the flame retardant salt comprises sodium chloride, potassium chloride, sodium bromide and / or potassium bromide, and is substantially composed of sodium chloride, potassium chloride, sodium bromide and / or potassium bromide, or is composed of sodium chloride, potassium chloride, sodium bromide and / or potassium bromide.

[0199] Depending on the desired flame retardant or other physical properties, the components of the salt can be in the form of a free alkali, a salt, a complex, or a solvate. The flame-retardant salt can have any density and any crystal structure.

[0200] In some embodiments, the flame-retardant salt is incorporated into or added to an amorphous solid material dissolved in a solvent or liquid carrier. In some embodiments, the flame-retardant salt is suspended in a liquid carrier. The solvent or liquid carrier may be aqueous or organic liquid, and may be polar or non-polar, depending on its suitable application.

[0201] The liquid carrier or precursor solvent can be advantageously selected to be easily removed during the manufacture of the flame retardant material so as to leave the flame retardant strip in or on the amorphous solid material.

[0202] In some embodiments, the liquid carrier is a mixture of liquids, including an aqueous liquid (water) and an anhydrous liquid (e.g., glycerol). When the water is removed after salt application, the glycerol will remain in the amorphous solid material, where it provides flexibility and facilitates aerosol formation upon heating.

[0203] In some embodiments, the described component 2 can be used for aerosol supply articles, and in some cases, non-combustible aerosol supply articles 3, typically such as Figure 3 As shown. The aerosol supply article 3 can be used as or as part of an aerosol supply system. The aerosol supply article 3 includes aerosol generating material 13 and components. Component 2 includes various fibers 5 formed from regenerated cellulose and about 5% to about 60% aerosol forming agent material.

[0204] In some embodiments, component 2 as described above may further comprise an active substance. The active substance may be a substance to be delivered to a user. As used herein, an active substance may be a physiologically active substance, which is a material intended to achieve or enhance a physiological response, as described in more detail below. The active substance may, for example, be selected from nutritional supplements, nootropics, and psychoactive agents. The active substance may be naturally occurring or synthetically obtained. The active substance may include, for example, nicotine, caffeine, taurine, theophylline, vitamins such as B6 or B12 or C, melatonin, or components, derivatives, or combinations thereof. The active substance may include one or more components, derivatives, or extracts of tobacco or another plant. In one embodiment, the active substance is a legally permissible recreational drug. In some embodiments, the active substance includes nicotine. In some embodiments, the active substance includes caffeine, melatonin, or vitamin B12.

[0205] In some embodiments, the active substance may include or be derived from one or more plant preparations or their components, derivatives, or extracts. The term "plant preparation" includes any material derived from a plant, including but not limited to extracts, leaves, bark, fibers, stems, roots, seeds, flowers, fruits, pollen, shells, etc. Alternatively, the material may include a naturally occurring, synthetically obtained active compound found in a plant. The material may be in the form of a liquid, gas, solid, powder, dust, crushed particle, granule, pellet, fragment, strip, flake, etc. Examples of such plants can be found in the list disclosed below.

[0206] In some implementations, the substance to be delivered may include a flavoring agent. Examples of such flavoring agents can be found in the list outlined below.

[0207] It should be understood that in some embodiments, when heated during use, the active substances or materials in material 1 can form aerosols, and therefore can be considered as aerosol forming agent materials.

[0208] Now refer to Figure 6 A perspective sectional view of the component. In one aspect of the invention, a component 2 for an aerosol supply article 3 is provided for use in an aerosol supply device 30. The component 2 for the aerosol supply article 3 can be used in a non-combustible aerosol supply device 30. Component 2 includes a material 1, which includes a plurality of fibers 5 comprising regenerated cellulose. The component also includes an aerosol modifier release component 40. The aerosol modifier release component 40 may be surrounded by a plurality of regenerated cellulose fibers 5.

[0209] Figure 6 The component 2 of the present aspect of the invention shown is similar to Figures 1 to 5 The components shown are from the previously described aspect of component 2, and therefore their detailed description will be omitted here. Furthermore, similar features and components will retain their terminology and reference numerals. It should also be understood that features and components of the aforementioned component 2 can be incorporated into component 2 of this aspect, and vice versa.

[0210] The aerosol modifier release component 40 can be disposed within the body of the material 1 within the component 2. In this embodiment, the aerosol modifier release component 40 can be in the form of an additive release component in the form of a capsule 41. In embodiments where a capsule 41 is provided, the filter rod forming paper 24 can include oil-resistant filter rod forming paper. However, in other embodiments, the aerosol modifier release component 40 can be provided in other forms, such as as material injected into the body of the material 1 of the component 2 or disposed on a thread (e.g., a thread carrying flavoring agents or other aerosol modifiers), which can also be arranged within the body of the material 1 of the component 2.

[0211] The aerosol modifier release component 40 can be a capsule 41. The capsule 41 can be a ruptureable capsule. For example, the ruptureable capsule 41 can have a solid, fragile shell 42 surrounding the liquid load 43. Figure 6 In the illustrated embodiment, component 2 includes a single capsule 41. However, in some embodiments, component 2 may include multiple capsules 41. For example, component 2 may include two, three, or more capsules 41.

[0212] The capsule 41 can be completely embedded within the body of the material 1 of the component 2. In other words, the capsule 41 can be completely surrounded by the material 1 forming the component 2. The body of the material 1 of the component 2 can be sufficiently uniform so that the capsule 41 is not visible from the ends of the component 2. In embodiments that include multiple capsules 41, the length of the component 2 can be increased, and thus the body of the material 1 can be increased to accommodate the number of capsules 41 included.

[0213] In embodiments using multiple capsules 41, the individual capsules 41 may be identical to each other, or they may differ from each other in size and / or capsule load 42.

[0214] Capsule 41 may have a core-shell structure. In other words, capsule 41 may include a shell 42 encapsulating a liquid payload 43. The liquid payload 43 may be a liquid reagent, such as a flavoring agent or other reagent, which may be any of the flavoring agents or aerosol modifiers described herein. The shell 42 of capsule 41 may be ruptured by a user to release the flavoring agent or other reagent into the material 1 forming the body of component 2.

[0215] In this embodiment, capsule 41 may also be generally spherical. The spherical capsule 41 may have a diameter of about 3 mm. In alternative embodiments, capsules 41 of different shapes and sizes may be used. For example, in some embodiments, the aerosol modifier release component 40 may be substantially cylindrical. In some embodiments, capsule 41 may have a diameter of less than 4 mm, or less than 3.5 mm, or less than 3.25 mm. In alternative embodiments, capsule 41 may have a diameter greater than about 3.25 mm, for example, greater than 3.5 mm or greater than 4 mm. The total weight of capsule 41 may range from about 10 mg to about 50 mg.

[0216] In this embodiment, capsule 41 may be located at the longitudinal center position within the material 1 of component 2. However, in some embodiments, capsule 41 may be located at a non-longitudinal center position within the material 1 of component 2. That is, capsule 41 may be located closer to the upstream end of component 2 than the downstream end of component 2.

[0217] For example, in a 12 mm long component, capsule 41 can be positioned such that its center is 5 mm from the upstream end of component 2 and 7 mm from the downstream end of component 2. This positioning of capsule 41 helps ensure that capsule 41 is not visible from the downstream end of the aerosol supply article 3.

[0218] In some embodiments, the shell 42 is formed of a barrier material. This barrier material may be brittle. The capsule 41 may be crushed or otherwise broken by the user to release the encapsulated aerosol modifier load. Typically, the capsule 41 breaks immediately before use, but the user may choose when to release the aerosol modifier. The term "ruptureable capsule" refers to capsule 41, in which the shell 42 can be broken by pressure to release the liquid load 43 within the core. More specifically, the shell 42 may break under pressure applied by the user's fingers when the user wishes to release the liquid load 43 within the core of capsule 41.

[0219] In some embodiments, the barrier material forming the shell 42 may be heat-resistant. That is, in some embodiments, the shell 42 will not crack, melt, or otherwise fail at the temperature reached at the location of the capsule 41 during operation of the aerosol supply article 3.

[0220] In an alternative embodiment, capsule 41 may be a biodegradable capsule. That is, capsule 41 may be configured to degrade to release the aerosol modifier when a temperature exceeding a predetermined threshold is applied. In some embodiments, capsule 41 may be configured to degrade to release the aerosol modifier when a moisture content exceeding a predetermined threshold is applied.

[0221] The component 2, which includes the aerosol modifier release component 40, can be formed by the following steps: extruding a plurality of fibers 5 containing regenerated cellulose and spunlace fibers 5 to form a nonwoven sheet of material 1; receiving the nonwoven sheet of material 1 and inserting the aerosol modifier release component 40 onto the nonwoven sheet of material 1; and processing the nonwoven sheet of material 1 such that the aerosol modifier release component 40 is surrounded by the nonwoven sheet of material 1.

[0222] In some embodiments, the described component 2 can be used in a non-combustible aerosol supply article 3, typically as follows: Figure 3 As shown. The aerosol supply article 3 can be used as or as part of an aerosol supply system. The aerosol supply article 3 includes an aerosol generating material 13. The aerosol generating material 13 includes at least one aerosol forming material. The aerosol supply article 3 further includes a component 2, which includes an aerosol modifier release component 40, as described above.

[0223] In some embodiments, the aerosol supply article 3 may include a plurality of components 2. Each component 2 provided may include one or more aerosol-modified release components 40. Alternatively, only one or some of the multiple components 2 may include one or more aerosol-modified release components 40.

[0224] Now for reference Figure 7A schematic perspective view of material 71 is shown. In one aspect of the invention, material 71 is provided for use as a component 2 in an aerosol supply article 3. Material 71 comprises a plurality of substrate sheets 72, 73 stacked on top of each other. At least one of the plurality of substrate sheets 72, 73 is formed of any one of: a plurality of regenerated cellulose fibers; or paper.

[0225] Figure 6 The material 71 of the present aspect of the invention shown is similar to Figures 1 to 5 The material 1 shown is a component 2 of the previously described aspect, and therefore its detailed description will be omitted here. Furthermore, similar features and components will retain their terms and reference numerals. It should also be understood that the features and components of the aforementioned material 1 can be incorporated into material 71 of this aspect, and vice versa.

[0226] In some embodiments, the material 71 of the present invention may be a nonwoven sheet comprising a plurality of regenerated cellulose fibers 5, as previously described. That is, each of the plurality of substrate sheets 72, 73 may be formed from a nonwoven sheet comprising a plurality of regenerated cellulose fibers. The regenerated cellulose fibers may be viscose fibers or lyocell or a combination of both. In other embodiments, the material 71 of the present invention may be a paper material. That is, each of the plurality of substrate sheets 72, 73 may be formed from a sheet of material 1 comprising paper.

[0227] However, it should be understood that in some embodiments, it is envisioned that at least one of the plurality of substrate sheets 72 may be formed from a nonwoven material sheet 1 containing a plurality of regenerated cellulose fibers, and at least one of the plurality of substrate sheets 73 may be formed from a material sheet containing paper.

[0228] It should also be understood that in some embodiments, at least one of the plurality of substrate sheets 72, 73 may be formed of non-regenerated cellulose materials and non-paper materials. For example, at least one of the plurality of substrate sheets 72, 73 may be formed of aerosol-generating materials, such as, but not limited to, tobacco materials, plant materials, amorphous solid materials, or charcoal paper. In some embodiments, one or more substrate sheets 73 of non-regenerated cellulose materials and non-paper materials may be located between the outer substrate sheets 72, 74 of the regenerated cellulose material and / or the paper materials 72, 74.

[0229] In some embodiments, the total weight of the plurality of substrate sheets 72, 73 can be in the range of about 40 gsm to about 90 gsm. In some embodiments, the plurality of substrate sheets 72, 73 can have the same weight. For example, material 71 may include three substrate sheets 72, 73, 74, and each of the substrate sheets 72, 73, 74 may have a weight of about 15 gsm.

[0230] In some embodiments, at least one of the plurality of substrate sheets 72, 73, 74 may have a different weight than at least another of the plurality of substrate sheets 72, 73, 74. For example, material 71 may include three substrate sheets 72, 73, 74. Two of these substrate sheets 72, 74 may have a weight of about 20 gsm, and the other substrate sheet 73 may have a weight of about 10 gsm.

[0231] In some embodiments where at least one of the plurality of substrate sheets 73 has a different weight than the other substrate sheets 72, 74, the substrate sheet with the lower weight may be located between the substrate sheets 72, 74 with the higher weight. This arrangement produces a material 71 with better operability by a manufacturing apparatus (not shown) when the apparatus only contacts the structurally stronger, higher-weight substrate sheet.

[0232] In some embodiments, one or more, but less than all, of the plurality of material sheets may contain an aerosol-modifying additive. The aerosol-modifying additive may be, for example, an aerosol-forming material or an active substance, or both. That is, in some embodiments, at least one of the plurality of substrate sheets may include an aerosol-modifying additive. In some embodiments, at least one of the plurality of substrate sheets may not contain an aerosol-modifying additive.

[0233] In some embodiments, at least one or more portions of the sheet may be treated with aerosol modifiers (such as flavoring agents), adsorbents (such as charcoal pellets), aerosol forming agents as defined herein, and / or active substances as defined herein (such as nicotine). Advantageously, treating one or more, but less than all, of these portions can allow the aerosol modifier to be positioned at a specific location within the material body, or help limit its migration within the material body. That is, in some embodiments, Now for reference Figure 8 The image shows component 75 for aerosol supply product 3, such as... Figure 3 As shown. Component 2 is formed of the previously described material 71. Component 2 includes a plurality of substrate sheets 72, 73, 74 aggregated into a generally prismatic shape. This shape may be generally cylindrical. At least one of the plurality of substrate sheets 72, 73, 74 is formed of regenerated cellulose or paper.

[0234] The filtration efficiency of component 75 can be improved by forming component 75 from multiple substrate sheets 72, 73, 74 made of regenerated cellulose or paper. That is, by using multiple substrate sheets 72, 73, 74 with a lower weight (gsm), material 71 can be aggregated in a more uniform manner. This is due to the lower strength of individual substrate sheets 72, 73, 74, which makes them more flexible. Component 75 may include multiple channels 76 formed by the gaps between the folds of the substrate sheets 72, 73, 74. Therefore, component 75 includes less variability in the size of the channels 76 (i.e., the gaps between the folds of material 71).

[0235] This reduction in the variability of channel 76 decreases the likelihood that the path through component 75 will have significantly lower resistance than other paths. Therefore, aerosols are less likely to flow primarily along the lower-resistance path. This means that the flow through the component is more uniform and there is a larger flow volume in each channel 76. With more uniform aerosol flow, this means that each channel 76 has a more uniform amount of aerosol flowing through it. Therefore, filtration efficiency is improved because areas of component 75 that typically do not receive large flow rates when using a single, heavier sheet can now filter a larger volume of aerosol.

[0236] A present aspect of the invention also provides a method of forming a component 75. The method includes providing a material 71 comprising a plurality of substrate sheets 72, 73, 74 stacked on top of each other, and assembling the material into a prismatic component 75. At least one of the plurality of substrate sheets 72, 73, 74 is formed of regenerated cellulose or paper.

[0237] Now for reference Figure 9 A schematic cross-sectional view of component 52 is shown. In one aspect of the invention, component 52 for aerosol supply articles is provided. Component 52 can be used in a non-combustible aerosol supply device 30. Component 52 includes a material body 54 having an annular cross-section. The annular material body 54 includes a plurality of fibers 5 formed of regenerated cellulose.

[0238] An annular material body 54 may form the outer segment 54 of component 52. The annular material body 54 may extend longitudinally through component 52. Component 52 may further include a longitudinally extending core portion 53. The outer segment 54 may extend longitudinally and around the core portion 53. The outer segment 54 is formed of material 1, which comprises a plurality of fibers 5 formed of regenerated cellulose.

[0239] Figure 9 The component 52 of the present aspect of the invention shown is similar to Figures 1 to 7The components shown are from the previously described aspect of component 2, and therefore their detailed description will be omitted here. Furthermore, similar features and components will retain their terms and designations. It should also be understood that features and components of the previously described component 2 can be incorporated into component 52 of this aspect, and vice versa.

[0240] The core segment 53 of component 52 may extend longitudinally along the length of the longitudinal axis X of component 52. In this embodiment, the core segment 53 may extend the length of component 52. The outer segment 54 may extend longitudinally along the length of the longitudinal axis X of component 52. In this embodiment, the outer segment 54 may extend the length of component 52. In some embodiments, component 2 may have a length ranging from about 4 mm to about 12 mm. In some embodiments, component 2 may have a length ranging from about 6 mm to about 8 mm.

[0241] The outer segment 54 may include a first end surface 56 and an opposing second end surface 57. In this embodiment, the first end surface 56 may extend in the same plane as the proximal end of the component 52, and the second end surface 57 may extend in the same plane as the distal end of the component 52. In this embodiment, the first and second end surfaces 56 and 57 may be congruent.

[0242] The outer segment 54 may surround the core segment 53. Therefore, the core segment 53 may be located radially inside the outer segment 54. The outer segment 54 is formed of a material 1 comprising a plurality of regenerated cellulose fibers 5. That is, as previously described, the material 1 may be processed to form the outer segment 54 of the component 52. The material 1 forming the outer segment 54 of the component 52 may be a nonwoven sheet 1 with or without longitudinal cuts and having any of the characteristics of the previously discussed embodiments.

[0243] In some embodiments, the core segment 53 may include a first material 61. The first material 61 may be formed from, for example, but not limited to, paper or regenerated cellulose materials, such as lyocell, viscose, rayon, viscose rayon, cupro fiber, and modal. The core segment 53 may be in the form of a hollow tubular element 62. That is, the material forming the core segment 53 may be formed as a hollow tubular element, such as a tube 62. The hollow tubular element 62 may include a cavity 64. The cavity 64 may be centrally located within the core segment 53.

[0244] In some embodiments, the hollow tubular element 62 may have a wall thickness ranging from about 0.5 mm to about 3 mm. In some embodiments, the hollow tubular element 62 may have a wall thickness ranging from about 1 mm to about 2.5 mm. In some embodiments, the hollow tubular element 62 may have a wall thickness ranging from about 1.2 mm to about 1.82 mm. In some embodiments, the hollow tubular element 62 may have a wall thickness ranging from about 1 mm to about 1.5 mm. In some embodiments, the cavity 64 may have a diameter ranging from about 2.5 mm to about 5 mm. In some embodiments, the cavity 64 may have a diameter ranging from about 3 mm to about 4.5 mm.

[0245] In this embodiment, the core segment 53 and the outer segment 54 of the component 52 can be formed coaxially. That is, the longitudinal axis extending through the center of the core segment 53 of the component 52 can coincide with the longitudinal axis extending through the center of the outer segment 54 of the component 52.

[0246] In some embodiments, the outer segment 54 may have an annular cross-section in a plane perpendicular to its longitudinal axis. Therefore, the first and second end surfaces 56, 57 may have an annular cross-section. The hollow tube 62 may also have an annular cross-section in a plane perpendicular to its longitudinal axis. The cavity 64 may have a generally circular cross-section in a plane perpendicular to its longitudinal axis. However, it should be understood that in alternative embodiments, the cross-sectional shapes of the outer segment 54, the hollow tubular element 62, and the cavity 64 may not be annular or circular.

[0247] In some embodiments, the core segment 53 may be formed solely of the cavity 64. That is, the core segment 53 may be formed of the cavity 64 defined by the inner surface of the annular outer segment 54, and the hollow tubular element 62 may be omitted. More specifically, the core segment 53 may not be formed of the first material, but may instead be formed of a material not present in the outer segment 54.

[0248] In some embodiments, the annular body of material 54 may also be surrounded by filter rod forming paper. The filter rod forming paper may have a weight greater than 50 gsm or greater than 60 gsm.

[0249] In some embodiments, component 52 may have a hardness in the range of about 85% to about 97%. In some embodiments, component 52 may have a hardness in the range of about 88% to about 96%.

[0250] In some embodiments, the inner circumferential surface of component 52 may include at least a portion of an amorphous solid material layer, as described previously herein. Partial or complete layers may be applied to the inner circumferential surface of the outer segment 54. Thus, an amorphous solid material can form a core. Alternatively, an amorphous solid material may be coated on the inner circumferential surface of the core segment 53.

[0251] It should be understood that the aforementioned component 52 can be used in various ways in articles according to the present invention, such as Figure 10 , Figure 11 and Figure 12 As shown in the diagram. For example, component 52 can be used as the nozzle end section of a filter element in an article, such as... Figure 10 As shown, or the upstream filtration section in the filter element, such as Figure 11 As shown, or used as a downstream aerosol generation component, such as Figure 12 As shown.

[0252] In some embodiments, the material ring 54 forming component 52 may comprise a plurality of fibers 5 formed from regenerated cellulose and an adhesive, as previously described herein. The ring of regenerated cellulose fiber material 54 and the adhesive may have a density of about 0.7 g / cm³. 3 To approximately 0.9 g / cm 3 Within the range, preferably about 0.8 g / cm³ 3 The bulk density. The stiffness of the ring-shaped regenerated cellulose fiber material 54 and the adhesive can be in the range of about 75% to about 98% for unwrapped materials, and about 85% to about 99% for wrapped materials. The packaging material surrounding the ring-shaped material 54 can have a weight greater than about 60 gsm.

[0253] Furthermore, it should be understood that, as previously disclosed, the annular material body 54 can be formed from multiple substrate sheets stacked on top of each other, as per [the previous disclosure]. Figure 7 As described. In some embodiments, each of the plurality of substrate sheets may be formed from a plurality of regenerated cellulose fibers. In some embodiments, at least one of the plurality of substrate sheets may be formed from paper.

[0254] refer to Figure 10 The image shows a cross-sectional view of an aerosol supply article 10'. The aerosol supply article 10' includes a rod 12 of aerosol generating material 13 and a filter element 22. The filter element includes a first segment formed by a first component 2 and a second segment formed by a second component 52. The first component 2 is located upstream of the second component 52. Therefore, the second component 52 forms the nozzle end of the aerosol supply article 10', and the first component 2 is adjacent to the rod 12 of the aerosol generating material 13. The first component 2 may be related to... Figures 1 to 8Component 2 as described in the text. Alternatively, the first segment can be formed from a known filter segment. Component 52 can be as described regarding... Figure 9 The component described.

[0255] refer to Figure 11 The diagram shows a cross-sectional view of an aerosol supply article 10''. The aerosol supply article 10'' includes a rod 12 of aerosol generating material 13 and a filter element 22. The filter element includes a first segment formed by a first component 52 and a second segment formed by a second component 2. The first component 52 is located upstream of the second component 2. Therefore, the second component 2 forms the nozzle end of the aerosol supply article 10'', and the first component 52 is adjacent to the rod 12 of the aerosol generating material 13. The first component 52 may be as described above. Figure 9 The described component. In this configuration, component 52 may be referred to as a cooling section or cooling zone. The second component 2 may be related to... Figures 1 to 8 Any of the components 2 described herein. Alternatively, the second section may be formed from a known filter section.

[0256] refer to Figure 12 The image shows a cross-sectional view of an aerosol supply article 10'''. The aerosol supply article 10''' includes a rod 12 of aerosol generating material 13 and a filter element 22. The filter element 22 includes components as shown in the image. Figures 1 to 8 The segment formed by component 2 as described in any of the above. Alternatively, the filter element can be formed from a known filter segment. (See reference...) Figure 9 As described, the rod 12 of the aerosol generating material 13 is formed by component 52. Therefore, component 52 forms the upstream end of the aerosol supply article 10'''. Component 52 may include an aerosol forming agent material for generating aerosols when heated during use. The cavity 56 of component 52 may be configured to receive a heating element from an aerosol supply device (not shown).

[0257] See now Figure 13 The diagram shows a perspective view of an aerosol supply article 83 including components 91 and 92 formed of material 1. In one aspect of the invention, components 91 and 92 for the aerosol supply article 83 are provided, the components including a body of material 1 comprising a plurality of fibers 5 comprising regenerated cellulose. The body of material 1 further includes an adsorbent material 84. The adsorbent material 84 may include at least one of carbon, silica, and CR20.

[0258] Figure 13 The components 91, 92 of the present aspect of the invention shown are similar to Figures 1 to 9The components shown are the same as those of components 2 and 52 in the previously described aspects, and therefore their detailed descriptions will be omitted here. Furthermore, similar features and components will retain their terms and designations. It should also be understood that the features and components of components 2 and 52 previously described can be incorporated into components 91 and 92 of this aspect, and vice versa.

[0259] Figure 13 The aerosol supply article 83 shown may be in a regular, king-size form, i.e., having a length ranging from about 75 mm to about 91 mm and a circumference ranging from about 23 mm to about 25 mm. The aerosol supply article 83 may include a rod 85 of aerosol generating material 86 wound in packaging material 87, the rod 85 being longitudinally connected to a filter tip 88 via a tipping material 89.

[0260] The filter tip 88 may include a first section 91 and a second section 92. The first section 91 may be the same as components 2, 52 previously described herein. The first section 91 may be located at the tip of the filter tip 88 and may be wrapped in the first filter rod forming paper 93.

[0261] The second segment 92 may be generally the same as components 2 and 52 described previously. The second segment 92 may be located at the aerosol-generating material end of the filter tip 88. The second segment 92 may contain an absorbent material in the form of multiple regenerated cellulose fibers 5, as previously described herein, having an adsorbent material 84 dispersed therein. The second segment 92 may be encased in the second filter rod forming paper 94.

[0262] The adsorbent material 84 may include activated carbon particles. The activated carbon particles may be, for example, but not limited to, coconut carbon provided in a 30 / 70 mesh size. However, other carbon and / or sizes may be used. For example, particle diameters may be in the range of about 0.1 mm to about 1.0 mm, or about 0.2 mm to about 0.9 mm, or about 0.2 mm to about 0.8 mm, or about 0.2 mm to about 0.7 mm, or about 0.2 mm to about 0.6 mm, or about 0.3 mm to about 0.9 mm, or about 0.3 mm to about 0.8 mm, or about 0.3 mm to about 0.7 mm, or about 0.3 mm to about 0.6 mm.

[0263] The second segment 92 may have approximately 12 mg of adsorbent material 84 per millimeter of length. The second segment 92 may also have approximately 4 mg of adsorbent material per millimeter of length, i.e., the fibers of regenerated cellulose 5. However, in alternative examples, the amount of adsorbent material 84 may be anywhere within the range of an average of 6 mg to 16 mg / mm length, or 7 mg to 16 mg, 8 mg to 16 mg, 9 mg to 16 mg, 10 mg to 16 mg, 11 mg to 16 mg, 12 mg to 16 mg, or 13 mg to 16 mg / mm length. The amount of adsorbent material (i.e., the fibers of regenerated cellulose 5) may be approximately 1.5 mg to approximately 8 mg / mm length, or 1.5 mg to 7 mg, 1.5 mg to 6 mg, 1.5 mg to 5 mg, or 1.5 mg to 4 mg. Each of the ranges given above may be used for a conventionally formatted filter 88, i.e., having a circumference of approximately 23 mm to 25 mm.

[0264] These parameters have been found to enable filter 88 to exhibit the desired pressure drop and hardness levels for consumer-acceptable aerosol supply products 83, while increasing the level of adsorbent material 84 or other particulate additives in filter 88 compared to known filters.

[0265] The increase in pressure drop and / or hardness percentage caused by the increase in the adsorbed dose per mm in component 92 of filter tip 88 can be offset by a decrease in the adsorbed dose (i.e., fiber 5 of regenerated cellulose per mm). Furthermore, the increase in pressure drop and / or hardness percentage caused by the increase in the adsorbed dose per mm in component 92 of filter tip 88 can be offset by a decrease in the amount of adsorbent material 84 per mm. In particular, the inventors have discovered that for conventional aerosol supply articles 83, the amount of adsorbent material 84 (in mg, C...) is... w / mm length) and the amount of absorbent material (i.e., the fiber of regenerated cellulose 5 (in mg, T) w The length (in mm) can be determined based on the following range: 10≤(C w + T w ≤20, These values ​​enable the components 92 of the filter 88 to exhibit appropriate filter pressure drop and hardness levels, as discussed earlier here.

[0266] If, for a conventional perimeter aerosol supply product 83, the amount of adsorbent material 84, measured in mg / mm length, and the amount of adsorbent material fall within the following range: 11≤(C w + T w ≤18, Or more specifically, within the following scope: 12≤(C w + T w ≤17, For products supplied with aerosols of standard circumference, the weight of adsorbent and absorbent used (in mg / mm length) is within other ranges, including 10 ≤ (C w + T w )≤ 19、10≤(C w + T w )≤ 18、10≤(C w + T w )≤ 17、11≤(C w +T w )≤ 20, 12≤(C w + T w )≤ 20、13≤(C w + T w )≤ 20, and 14≤ (C w + T w The advantages can also be achieved if the value is less than or equal to 20.

[0267] In addition to the selected adsorbent material 84 and absorbent weight per mm falling within the above range, the adsorbent material 84 and absorbent weight C w T w At least one of the levels can be greater than the minimum level. For example, in some embodiments of the invention, the absorbent level can be equal to or greater than about 1.5 mg / mm. For example, in some embodiments of the invention, the level of adsorbent material 84 can be equal to or greater than 6 mg / mm. For conventional perimeter aerosol supply articles 84, both minimum levels are about 23 mm to about 25 mm.

[0268] The above scope can also be applied to particulate additives other than adsorbents, such as certain flavorings.

[0269] The second segment 92 can be manufactured using filter manufacturing equipment, such as the Turmalin equipment from Hauni Maschinenbau AG in Germany.

[0270] When the adsorbent weight / mm is less than 3.5 mg / mm and / or the adsorbent material 84 weight / mm is less than 9 mg / mm (both used in conventional perimeter aerosol supply articles 83), and / or the combined adsorbent material 84 and adsorbent weight / mm is at the lower limit of the above range, for example, 12 mg / mm or lower, the inventors have determined that the reduction in stiffness caused by these low weights can be offset by using, for example, a more rigid filter rod forming paper and / or a more rigid tipping material surrounding the component. For example, the filter rod forming paper and / or tipping material can have a stiffness greater than 30 g / m².2 Greater than 40 g / m 2 Greater than 50 g / m 2 Greater than 60 g / m 2 Greater than 70 g / m 2 or greater than 80 g / m 2 The basis weight. Alternatively, multi-layer filter rod forming paper and / or tipping material can be used.

[0271] Known conventional forms of filter tips (containing carbon particles dispersed in continuous cellulose acetate tows cut to the desired segment length) typically have a carbon loading limit of 5 mg / mm to maintain the pressure drop at the level desired by the consumer. Higher loading can lead to excessive pressure drop. If a higher loading is desired, a cavity tri-filter is usually necessary, having cellulose acetate tow segments at the nozzle end and aerosol-generating material end, with a carbon-filled cavity between them. Such cavity filters result in the removal of a certain amount of cellulose acetate for a given fiber length, and therefore this can negatively impact, for example, certain aspects of filtration and phenol sensitivity. Therefore, there is a clear advantage to filter materials capable of increasing the loading of additives without causing excessive pressure drop and without removing regenerated cellulose fibers.

[0272] The inventors have recognized that by using randomly oriented discrete short-length regenerated cellulose fibers to form a component 82 (e.g., filter segment 92) manufactured using a filter manufacturing apparatus (e.g., Turmalin), and by selecting the amount of adsorbent material 84 to be in the range of about 6 mg to about 16 mg / mm on average, and the amount of adsorbent, i.e., the average range of the regenerated cellulose fiber 5, to be about 1.5 mg to about 8 mg / mm (or within other ranges and limitations previously outlined), an improved filter component 92 can be provided for conventional circumference aerosol supply articles 83 while maintaining acceptable pressure drop and filter stiffness parameters.

[0273] Reference Figure 14 A schematic diagram of a component manufacturing apparatus 100 (such as a Turmalin apparatus) for manufacturing filter tips. The components formed in the component manufacturing apparatus 100 can be used as filter tip segments. (See reference...) Figure 14A source 101 of multiple regenerated cellulose fibers is supplied to a filter manufacturing apparatus comprising multiple modules 102-106. In an embodiment where regenerated cellulose fiber tows are supplied to apparatus 100, feeder module 102 receives the supply of regenerated cellulose fibers 5 from feed to cutter and randomizer 23. Cutter and randomizer 23 can cut the regenerated cellulose fibers 5 into short fiber lengths as previously described. In an embodiment where material 1 comprising multiple hydroentangled or wet-woven regenerated cellulose fibers 5 is supplied to apparatus 100, cutter and randomizer 23 may be omitted. Filter bander 104 includes a vacuum belt on which the regenerated cellulose fibers 5 are disposed. It is fed into rod former 105 for forming the regenerated cellulose fiber band 5 into rods wrapped with filter rod forming paper. Finally, component cutter 106 is used to cut the rods into components of desired lengths.

[0274] The filter tip packaging machine 104 may include a carding unit and multiple hoppers that distribute material 1 onto a vacuum belt. These hoppers are used to apply additives, such as granules or additional fibers. An add-back system may also be present, which can be used (if needed) to feed a third additive into the regenerated cellulose fiber belt 5. Alternatively, the add-back system can be used to add any loosely cut filter tip material back into the feeder module 102 to reduce waste. The filter tip packaging machine 104 may include metering rollers that are adjustable to allow control of the additive loading and ensure the uniformity of the regenerated cellulose fiber belt. The filter tip packaging machine 24 may also include a jet inserter for allowing liquids, such as flavoring agents, to be directly injected into component 82.

[0275] In use, the Turmalin device 100 operates as follows: The feeder module 102 supplies the regenerated cellulose fiber bundle 5 to the cutter and randomizer 103. When using material 1 as described above, the cutter and randomizer 103 can be omitted. The regenerated cellulose fibers 5 are transferred to the carding unit of the filter bagger 104, from which they are drawn onto a vacuum belt. Additives are fed into the airflow carrying the regenerated cellulose fibers 5, and the rod maker 25 forms the belt into a continuous section 92, which is bound by filter rod forming paper. The cutter 106 cuts the continuous section containing the regenerated cellulose fibers 5 into sections of the desired length.

[0276] The significant advantages of the Turmalin device 100 include: the ability to contain higher loadings of additives, such as carbon; retention of the activity of the carbon additives because there are no plasticizers such as triacetin, and no carbon poisoning; and a longer product life. Further advantages and improvements have been achieved through filter design and manufacturing developments by the inventors, as described below.

[0277] Although the additives in the previously described embodiments have been described as being able to be particles of adsorbent material 84, particularly activated carbon, other adsorbent materials 84, or other additives. For example, the adsorbent can be an ion exchange resin, such as CR20, or other materials such as zeolite, silica gel, sepiolite, alumina (activated or unactivated), carbonized resin, magnesium silicate, including sepiolite (Mg4Si6O). 13 (OH)2 (6H2O) or a combination thereof with or without activated charcoal. Additionally, other additives that alter the smoke produced by inhaling component 84 may be used, such as flavoring agents, for example menthol crystals, or humectant particles.

[0278] Manufacturing filters containing randomly oriented discrete cellulose acetate fibers is previously known. However, similar to conventional cellulose acetate tow filters, the manufacturing process may require the use of plasticizers, such as triacetin, to bond the randomly oriented fibers into a robust structure. However, the advantage of the Turmalin device is that it does not require the use of plasticizers. In embodiments where regenerated cellulose fiber tows are fed into the device, the Turmalin device 100 induces mechanical bonding within the cut fibers, thus eliminating the need for plasticizers. This eliminates any undesirable effects caused by the use of products such as triacetin.

[0279] In addition to the advantages mentioned above, the inventors have recognized that the Turmalin device or similar device enables various component designs that provide additional improvements and advantages.

[0280] Now for reference Figure 15 A schematic diagram of an aerosol supply article 111 is shown. The aerosol supply article 111 shown is similar to... Figure 13 The aerosol supply article 111 shown and previously described herein. The first paragraph 91 may include, as previously referenced... Figures 2 to 13 The regenerated cellulose fiber 5 described in the text is segment 2.

[0281] The second segment 92 may include a first absorbent material 113 and a second absorbent material 114 wrapped within a second filter rod forming paper 94. The second absorbent material 114 may be dispersed within the first absorbent material 113. The first absorbent material 113 may include a plurality of regenerated cellulose fibers 5 having a monofilament denier in the range of about 1 to about 10. The second absorbent material 114 may include a plurality of regenerated cellulose fibers 5 having a monofilament denier of about 20 to about 30.

[0282] The second segment 92 can be manufactured using the Turmalin apparatus 100. The second segment 92 can be manufactured by supplying the first absorbent material 113 to the feeder 102 and by adding the second absorbent material 114 via one of the additive hoppers in the filter bag 104. Alternatively, the first and second absorbent materials 113, 114 can each be supplied to the feeder 102 of the apparatus 100.

[0283] Although the second absorbent material 114 has previously been described as a plurality of regenerated cellulose fibers 5, alternative materials may also be used. For example, the fibers of the second absorbent material 114 may include polyvinyl alcohol (PVOH), polylactic acid (PLA), poly(ε-caprolactone) (PCL), poly(1-4-butylene glycol succinate) (PBS), poly(decyl adipate-co-butylene terephthalate) (PBAT), starch-based materials, paper, aliphatic polyester materials, and polysaccharide polymers, or combinations thereof.

[0284] Further advantages can be achieved by using nanofiber materials as the basis for catalysts to enhance filtration performance. Nanofibers possess a sufficiently high surface area to volume ratio to exhibit catalytic activity potential. Such nanofibers can be used, for example, when loading additives through one or more hoppers in a filter bagger 104. Figure 14 The device is added to the filter tip so that the nanofibers are metered and supplied to the airflow inside the filter tip packaging machine 104.

[0285] Figure 16 A schematic diagram of an aerosol supply article 111 is shown, which has a component 92 comprising nanofibers 115 carrying additives for enhancing or enabling the reduction of at least one component of the mainstream aerosol drawn through the aerosol supply article 111 during use. Figure 16 The aerosol supply product 111 shown in the figure and Figure 13 The aerosol supply article 111 shown is substantially the same, and therefore its detailed description will be omitted here. Furthermore, similar features and components will retain the same terminology and reference numerals.

[0286] Nanofibers 115 may comprise carbon nanotubes 115a loaded with zinc oxide (ZnO) particles, the zinc oxide particles acting as catalysts 115b, for example, enhancing the reduction of HCN in aerosols. In alternative embodiments, other nanofiber materials and / or other catalysts, such as gold (Au), may be used alone or in combination (including in combination with carbon and / or ZnO) for the reduction of carbon monoxide (CO) from aerosols. Nanofibers 115a may be added as an additive to the plurality of fibers 5 of regenerated cellulose using the previously described apparatus 100.

[0287] The nanofibers 115 can have any suitable length for inclusion in the component 92, such as 1 mm to 15 mm, or from 1 mm to 12 mm. The diameter of the nanofibers 115 used can be 25 nm to 900 nm, or 50 nm to 500 nm, or 100 nm to 300 nm.

[0288] See now Figure 17 A schematic diagram of an aerosol supply article 111 comprising a plurality of regenerated cellulose fibers 5, having a rope 116 extending through it. Figure 17 The aerosol supply product 111 shown is Figure 13 The aerosol supply article 111 shown is substantially the same, therefore its detailed description will be omitted here. Furthermore, similar features and components will retain the same terminology and reference numerals.

[0289] The cord 116 can be used as a carrier to add flavoring to component 82. A cord insertion device (not shown) can be installed in the central portion of the filter vacuum belt, wherein the cord insertion needle carries the cord into the axial region of component 82 as component 82 is formed. The embodiments described herein involving the insertion of cord 116 into component 82 are particularly advantageous in thin and ultra-thin forms (i.e., less than 22 mm). Cord 11 can extend axially through the second segment 92.

[0290] See now Figure 18 A schematic diagram of an aerosol supply article 111 comprising a plurality of regenerated cellulose fibers 5 is shown, having an aerosol modifier release component 117 in capsule form disposed therein. Figure 18 The aerosol supply product 111 shown in the figure and Figure 13 The aerosol supply article 111 shown is substantially the same, and therefore its detailed description will be omitted here. Furthermore, similar features and components will retain the same terminology and reference numerals.

[0291] The inventors also recognize that the Turmalin device 100, etc., can be arranged to allow capsule 117 to be contained within a plurality of regenerated cellulose fibers 5 while ensuring uniform distribution of capsule contents (such as flavoring agents). In some embodiments, capsule 117 may be a microcapsule or other encapsulation material.

[0292] In a manner similar to that described regarding carbon loading, such materials can be added at higher levels to deliver more flavoring. Capsules (whether larger capsules, such as those with a diameter of 3 mm to 8 mm, microcapsules, or other encapsulating materials) can be pushed into multiple regenerated cellulose fibers 5 in device 100 (such as a Turmalin device) by guiding capsules 117 through a tube into the regenerated cellulose fibers 5 at the downstream end of filter packer 104. Capsules 117 can be blown into the regenerated cellulose fibers 5, for example, using high-pressure gas at a frequency corresponding to the speed of filter packer 104, such that capsules 117 are positioned at appropriate intervals in the resulting portions 82, 92, and the portions 82, 92 cut from the continuous bar contain the desired number of capsules 117. Alternatively, one of the previously described additive hoppers can be used to meter microcapsules onto the filter belt in a manner similar to that used for additives.

[0293] An aerosol modifier release component for a capsule-shaped flavoring agent (capsule 117) can be arranged within the second segment 92. (Brief reference) Figure 19 A schematic diagram is shown of an aerosol supply article 83 comprising a plurality of regenerated cellulose fibers 5, having an aerosol modifier release component 117 in the form of microcapsules disposed therein. The aerosol modifier release component having an encapsulated flavoring agent, in this embodiment in the form of microcapsules 118, can be arranged within the second segment 92.

[0294] Reference Figure 20 A schematic diagram of an aerosol supply article 83 comprising a plurality of regenerated cellulose fibers 5 is shown, having shredded material 119 disposed therein. Figure 20 The aerosol supply product 83 shown in the figure Figure 13 The aerosol supply article 83 shown is substantially the same, and therefore its detailed description will be omitted here. Furthermore, similar features and components will retain the same terminology and reference numerals.

[0295] In addition to encapsulated flavorings, other forms of flavoring additives can be added to the filter containing multiple regenerated cellulose fibers 5. For example, flavoring additives can be added in botanical form, such as mint or tobacco leaves or other plant leaves, seeds, or peels, as previously described herein and outlined in more detail below. Such additives can be added to the additive hopper in the tape-forming machine of the apparatus 100, and thus metered into the regenerated cellulose fiber airflow during filter tape formation or component formation. In some embodiments, because plasticizers are not used, the release of aroma from the botanical additives can be enhanced.

[0296] In some embodiments, shredded material 119 may be contained within a material formed from a plurality of fibers 5 comprising regenerated cellulose. Such a sheet may include sheets formed from plants such as peppermint or menthol, tobacco, or reconstituted tobacco. Those skilled in the art will recognize that the provided list is not limiting and that any suitable sheet may be used. The benefits of using such materials in shredded form are that they can improve the dispersibility of the material within components 82, 92 and also improve the biodegradability of components 82, 92. Furthermore, the use of novel materials can be used to improve the performance of components 82, 92 and / or alter the characteristics of the aerosol inhaled through components 82, 92.

[0297] Shredded material 119 may include materials formed from the following fibers: polyvinyl alcohol (PVOH), polylactic acid (PLA), poly(ε-caprolactone) (PCL), poly(1-4-butanediol succinate) (PBS), poly(decyl adipate-co-terephthalate) (PBAT), starch-based materials, paper, aliphatic polyester materials, and polysaccharide polymers, or combinations thereof.

[0298] The inventors also recognized the potential of combining biodegradable or alternative fibers (such as PVOH fibers) with regenerated cellulose fibers. PVOH is not typically used in conventional filter manufacturing because it cannot usually be crimped. However, incorporating PVOH or other non-crimped fibers with regenerated cellulose fibers means that this problem can be overcome. Using such materials can result in components with improved biodegradability and water solubility.

[0299] In some embodiments, to add PVOH or other non-crimped fibers to a component, or PLA or other crimped fibers to a component, the feeder module 102 of device 100 may be arranged to feed two raw material ropes into the cutter and randomizer 23. Thus, the number of processing steps is reduced by straightening the material as a tow instead of first converting it into sheet material.

[0300] Furthermore, if the step of orienting the material in the tow material is omitted, the number of processing steps can be further reduced. In such embodiments, feeding, cutting, or randomizing these fibers is not required. Instead, the raw material fiber form can be directly mixed with the plurality of regenerated cellulose fibers 5 in the direct insertion device 100.

[0301] In other embodiments, one of the above-described additive hoppers can be used to meter non-crimped fibers of other crimped fibers into the regenerated cellulose fibers 5 in the filter bag 104.

[0302] In one aspect of the invention, a material 121 is provided for the component 2 of the aerosol supply article 3, such as... Figure 21 As shown. Material 121 includes a first plurality of fibers 122 and a second plurality of fibers 123. The first plurality of fibers 122 are formed of a first material. The second plurality of fibers 123 are formed of a second material. The first material is different from the second material.

[0303] In some embodiments, the first plurality of fibers 122 may be formed of regenerated cellulose. The regenerated cellulose fibers 122 may be the same as the regenerated cellulose fibers previously described in this application.

[0304] In some embodiments, the second plurality of fibers 123 may be formed from regenerated cellulose. The regenerated cellulose fibers 122 may be the same as the regenerated cellulose fibers previously described in this application. However, the first plurality of fibers 122 may be formed from, for example, viscose, rayon, viscose rayon, and lyocell, while the second plurality of fibers 123 may be formed from, for example, a different one of viscose, rayon, viscose rayon, and lyocell.

[0305] In some embodiments, the second plurality of fibers 123 may be formed of a non-regenerated cellulose material. For example, the second plurality of fibers 123 may be formed of at least one of cellulose acetate, polylactic acid, and paper.
