[0002] Popular aerosol generating articles can have a generally cylindrical rod-like structure and can comprise a pack, roll, or column of a vaporizable material, such as shredded tobacco (e.g., in the form of cut filler), surrounded by wrapping paper, thus forming a rod of atomizable material. Typically, aerosol generating articles have a filter element aligned end-to-end with the rod of atomizable material.

Detailed Implementation

[0047] See now Figure 1 This shows the aerosol supply product 3 (in Figure 3 As shown in the figure, it is used as part 2 (in Figure 2 Material 1 (shown in the diagram). 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 about 0.1 g / cm³. 3 To approximately 0.40 g / cm 3 The packing density within the range.

[0048] The multiple regenerated cellulose fibers 5 can be discontinuous fibers. The multiple fibers can be spunlace.

[0049] 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.

[0050] 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. In some embodiments, material 1 may have a bulk density of about 0.10 g / cm³. 3 To approximately 0.30 g / cm 3 The bulk density is within the range. In some embodiments, material 1 may have a bulk density of about 0.13 g / cm³. 3 To approximately 0.18 g / cm 3 The bulk density is within the range. In some embodiments, material 1 may have a bulk density of about 0.15 g / cm³. 3 Approximately 0.17 g / cm³ 3 The bulk density.

[0051] 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, reducing the bulk density of material 1 improves cost efficiency and material usage, and thus reduces the manufacturing impact on the environment.

[0052] 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.

[0053] 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 component. In this sense, the 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 component. For example, the component 2 formed from the material 1 can be included in the aerosol supply article 3 to help achieve the required pressure drop on the aerosol supply article 2.

[0054] 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 component 2. Component 2 may form the filter section and / or aerosol generating section 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 filter sections of, for example, conventional cigarettes (e.g., cellulose acetate).

[0055] 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 include any of the disclosed fibers 5 alone or in combination with one or more other fiber inlets. Fibers may be in the form of ropes or rope-like elements. The term "fiber" is intended to include fibers, filaments, etc.

[0056] 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 filters (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.

[0057] 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 forced 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 plurality of regenerated cellulose fibers 5 can be, for example, but not limited to, viscose, lyocell, rayon, viscose rayon, cuprammonium cellulose, and modal fibers.

[0058] In some embodiments, the plurality of fibers 5 may be composed of regenerated cellulose. In some embodiments, the plurality of fibers 5 may comprise between 90% and 100% by weight of these fibers contained within the material.

[0059] In some embodiments, the plurality of regenerated cellulose fibers 5 are composed of lyocell fibers 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.

[0060] The denier of the multiple regenerated cellulose fibers 5 can range from 1 to 30 denier (dpf). Denier, or denier / fiber, is a measurement of the weight per unit length of a single filament of a fiber. The denier of regenerated cellulose fibers is expressed in grams per 9000 meters. The denier 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).

[0061] In some embodiments, the denier 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 of the plurality of regenerated cellulose fibers 5 can be in the range of about 1 dpf to about 10 dpf.

[0062] In some embodiments, the denier of the single filaments of the plurality of regenerated cellulose fibers 5 may range 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 of the single filaments of the plurality of regenerated cellulose fibers 5 may range 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.

[0063] 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 first plurality of regenerated cellulose fibers may have a greater denier (dpf) than the second plurality of regenerated cellulose fibers. The first plurality of regenerated cellulose fibers may be formed from regenerated cellulose fibers with a 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 denier of about 1 dpf to about 10 dpf.

[0064] 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.

[0065] 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.

[0066] In some embodiments, the second plurality of regenerated cellulose fibers 5 may be formed from regenerated cellulose fibers having a denier of monofilament 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.

[0067] 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.

[0068] In some embodiments, the plurality of regenerated cellulose fibers 5 may comprise more than two fibers with different denier / filament deniers. In some embodiments, the plurality of regenerated cellulose fibers 5 may include a first plurality of regenerated cellulose fibers having a monofilament denier of about 5 dpf to about 10 dpf, a second plurality of regenerated cellulose fibers having a monofilament denier of about 2 dpf to about 5 dpf, and a third plurality of regenerated cellulose fibers having a monofilament denier of less than about 2 dpf.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] It has been found that combinations of first and second, and optionally additional, regenerated cellulose fibers with different monofilament deniers 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 and second 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.

[0074] 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 porosity in the components formed from said spunlace regenerated cellulose materials. Generally, the greater the material stiffness, the greater the porosity.

[0075] The porosity can be considered as the amount of space between materials when the material is aggregated into a component, compared to the cross-sectional area of ​​the component. When aggregated into a component, the porosity of the material can range from about 5% to about 30%, depending on the fiber's dpf.

[0076] 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%.

[0077] 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.

[0078] In some embodiments, the cross-sectional shape of these fibers in a 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, the fine filter material segment is located downstream of a segment formed from material 1, and at least some of the plurality of regenerated cellulose fibers 5, or each of them, may have a diameter of less than 10 μm.

[0079] 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.

[0080] 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.

[0081] 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 materials can have thicknesses between 60 and 500 µm or between 150 and 350 µm.

[0082] 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, matte, or sheet material in which a plurality of regenerated cellulose fibers are arranged in an undefined or random orientation.

[0083] To form material 1, multiple nonwoven regenerated cellulose fibers initially exist as unbonded fibers or filaments. These fibers or filaments can then be bonded together.

[0084] 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.

[0085] 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 in 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 a material that is more easily aggregated into rod-shaped components, and thus the final formed component exhibits less and smaller porosity.

[0086] 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.

[0087] The rod-shaped component 2 can then be wrapped with material to form a continuous rod, which can be used as component 2 in the aerosol supply article 3, such as a filter component. The width of the sheet material 1 can vary. Typically, the width of the sheet material 1 is such that it can be pleated to form component 2.

[0088] The total width of the sheet material 1 used to form component 2 can depend on a number of factors, such as the thickness of sheet material 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 water content of the material, the lubrication characteristics of the material, the frictional characteristics of the mesh preforming device relative to sheet material 1, and other such factors.

[0089] 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.

[0090] 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 the pressure drop across component 2. The longitudinal cutting of the sheet of material 1 allows material 1 to expand or “bloom,” providing enhanced filtration performance.

[0091] In some embodiments, the nonwoven sheet of material 1 may undergo a crimping step. Crimping can be considered a parameter relating to the texture or waviness of a single regenerated cellulose fiber 5, or as a parameter relating to the overall texture or waviness of the nonwoven sheet of material 1. The amplitude or depth of a single crimp can be measured in micrometers. The amplitude or depth of a single crimp is an indirect measure of the degree of crimping applied to the nonwoven sheet of material 1.

[0092] 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 achieve 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.

[0093] In some embodiments, the crimping roller may be an electropolished crimping roller. It has been found that electropolished crimping rollers allow the sheet material 1 to be crimped to a greater depth while causing less damage to the multiple regenerated cellulose fibers.

[0094] 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.

[0095] 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 120g / m 2 Within the range. In some embodiments, the basis weight of the nonwoven sheet of material 1 can be approximately 50 g / m². 2 Approximately 90 g / m 2 Within a certain range.

[0102] See brief Figure 2 The diagram illustrates 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 material 1 comprises a plurality of nonwoven regenerated cellulose fibers 5.

[0103] 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.

[0104] 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.

[0105] Contains Figure 2 and Figure 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.

[0106] 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 circumferential 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 between about 2 mm / WG / mm in length of component 2 and about 4.5 mm / WG / mm in length of component 2. In some embodiments, the pressure drop can be in the range between about 4.5 mm / WG / mm in length of component 2 and about 6.5 mm / WG / mm in length of component 2.

[0107] Furthermore, the component 2 formed from the material 1 comprising a plurality of regenerated cellulose fibers 5 can exhibit a desired stiffness. In some embodiments, the component 2 can have a stiffness in the range of approximately 70% to approximately 99%. In some embodiments, the component 2 of the present invention can exhibit a stiffness of approximately 75% or higher, approximately 80% or higher, approximately 85% or higher, or approximately 90% or higher. In some embodiments, the stiffness of the component 2 can be in the range of approximately 85% to approximately 93%. In some embodiments, the component may include a molding paper or other wrapping material surrounding the material 1 having a basis weight of 60 gsm or higher. A component surrounded by a wrapping material having a basis weight of 60 gsm or higher contributes to increasing the stiffness of the component.

[0108] 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.

[0109] Stiffness is defined as the ratio between body height h0 and body height h1 under a defined load, expressed as a percentage of h0. Stiffness can be expressed as: Hardness = (h1 / h0) × 100 For individual bodies, or bodies contained in multi-segment rods, perform hardness measurements at the longitudinal center point of the body or multi-segment rod (as specified).

[0110] The 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 environmental conditions according to ISO 3402:2023 during the measurement.

[0111] To perform hardness measurements, the body was placed in a hardness tester H10, and a preload of 2g was applied to the body. After 1 second, the initial height h0 of the body 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 body under the 150g load was measured.

[0112] The hardness of the component was determined as the average hardness of at least 20 components measured according to the scheme.

[0113] 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.

[0117] The described base rod component can be cut into 8 segments, such that each segment, used in the filter section of the product or as a filter section for the product, is approximately 10 mm long. Therefore, the parameters given above can be divided by 8 to obtain the parameters for a single segment. The pressure drop on the 10 mm segment 2 can be in the range of approximately 42 mmWG to approximately 55 mmWG.

[0118] In one embodiment, component 2 may be formed from a hydrospunlace nonwoven sheet material 1.

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 filtration section of the article or as a filtration section of the article. Thus, the parameters given above can be divided by 4 to achieve the parameters of a single segmented component.

[0120] Now for reference Figure 4 An 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 flat.

[0121] 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 feed or roller for the 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.

[0122] The rod 12 of the aerosol generating material 13 can be contained within an external wrapping material 14. The end of the rod 12 can be open to expose the aerosol generating material 13.

[0123] 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).

[0124] 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.

[0125] 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 packing layer 24 along its outer circumference or longitudinal periphery to form the filter element 22. The filter element 22 may be positioned adjacent to one end (i.e., proximal end 19) of the rod 12 of the aerosol generating material 13, 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.

[0126] The aerosol supply article 10 may further include a tipping paper 25. The tipping paper 25 may be attached to at least a portion of the outer circumference of the outer forming paper 24 of the filter element 22 and at least a portion of the wrapping material 14 of the rod 12 of the aerosol generating material 13. Thus, the tipping paper 25 may be configured to attach the filter element 22 to the rod 12 of the aerosol generating material 13.

[0127] The tipping paper 25 may be airtight. In some embodiments, the tipping paper 25 may extend over the entire length of the filter element 22 and over the adjacent area of ​​the rod 12 of the aerosol generating material 13. The inner surface of the tipping paper 25 may be securely attached to the outer surface of the forming paper 24 and the outer surface of the wrapping material 14 of the rod 12 of the aerosol generating material 13. A suitable adhesive may be used to securely attach the tipping paper 25 to the forming paper 24 and the wrapping 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.

[0128] In some implementations, such as Figure 4In 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 paper 25 and the packaging material 14. The series of perforations 27 may 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 formed paper and / or pre-perforated filter wrappings.

[0129] For the permeable 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 expansion" 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 terminal portion of the aerosol supply article 10.

[0130] The filter element 22 may include an inlet 29. The inlet 29 may be the end of the aerosol supply article 10. The inlet 29 may be configured to be placed in the user's mouth for the user to inhale during use.

[0131] 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.

[0132] 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 their components. The sensations provided may include inhalation and exhalation rituals, type of flavor or aroma, sensory effects, physical sensations, ritual 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 components 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 take a single inhale at selected time intervals.

[0133] See now 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.

[0134] 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 substantially rod-shaped, substantially tubular, or substantially cylindrical, such as... Figure 5 As shown in the image. That is to say, 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.

[0135] The alignment of the aerosol supply article 10 within the aerosol supply device 30 can be varied. In some embodiments, the base 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 base portion, the aerosol is formed, released, or generated in a physical form suitable for inhalation by the consumer.

[0136] 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, indicators, etc., as described in more detail below. In some embodiments, the power source may be able to deliver 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 handled. 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.

[0137] 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, including 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.

[0138] 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.

[0139] 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 content of approximately 0.1 g / cm³. 3 To approximately 0.4 g / cm 3 The packing density within the range.

[0140] 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-laid. 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 Approximately 0.3 g / cm³ 3 The bulk density of 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.

[0141] 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 terminology 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.

[0142] The nonwoven sheet of Material 1 can be produced by conventional forming methods such as wet web forming. It is known in industry that the term wet web forming has a broad meaning and can be combined with various equipment, methods, and means. The use of the term wet web forming is not restrictive and is not limited to a single process used for manufacturing.

[0143] Multiple fibers 5 can be wet-laid. As used herein, the term "wet-laid" generally refers to a method of producing a fiber 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.

[0144] 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.

[0145] When material 1 is formed into component 2 or article 3, the bulk density of the multiple fibers 5 of regenerated cellulose can be calculated without considering any other characteristics of material 1, component 2 or article 3.

[0146] As described above, the multiple fibers 5 of the regenerated cellulose material can have a density of approximately 0.10 g / cm³. 3 To approximately 0.40 g / cm 3 The bulk density is within the range. 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. In some embodiments, the plurality of fibers 5 of the regenerated cellulose material may have a bulk density of about 0.15 g / cm³. 3 To approximately 0.25 g / cm 3 The packing density within the range.

[0147] 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, reducing the bulk density of material 1 improves cost efficiency and material usage, and thus reduces the manufacturing impact on the environment.

[0148] 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.

[0149] 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.

[0150] 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, glyceryl triacetate, carbon wax, 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 component 2 into which material 1 is formed. For example, each coating, filler, or other component may contribute to filtering aerosols, improving aerosol flavor, water dispersibility, biodegradability, and / or compostability.

[0151] 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. Adhesive (which may contain pectin in some embodiments) may be applied to the nonwoven sheet of material 1 in conventional amounts using known techniques.

[0152] 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.

[0153] 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 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.

[0154] 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% pectin of component 52.

[0155] In one aspect of the invention, a component 2 for an aerosol supply article 3 is provided. The component 2 includes an aerosol generating material 1 comprising a plurality of fibers 5 formed from regenerated cellulose. The aerosol generating material 1 of the component 2 further comprises an aerosol forming material ranging from about 5% to about 60% by weight of the aerosol generating material 1.

[0156] 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 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.

[0157] Aerosol-forming materials may include one or more components capable of forming aerosols. In some embodiments, the aerosol-forming material may comprise 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 material 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 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 transfer from component 2 to the user during use.

[0158] Aerosol-forming materials may contain acids. Without being bound by theory, it is believed that the inclusion of acids reduces the perceived roughness of the generated aerosols.

[0159] Material 1 may comprise an aerosol-forming material. In some embodiments, the aerosol-forming material of Material 1 may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol may be present in an amount from 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 from 0.1% to 0.3% by weight of the composition.

[0160] 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 that may be configured to be heated (if present). In either case, the total amount of aerosol-forming material in material 1 may be as defined herein.

[0161] In one embodiment, the aerosol forming material may comprise an amorphous solid material comprising 40% menthol, 16% glycerol, 20% binder (alginate / pectin mixture), and 20% fiber (wood pulp).

[0162] 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.

[0163] In some other embodiments, the amorphous solid comprises: 1 wt%-50 wt% of a gelling agent; 0.1-50 wt% of an aerosol forming agent; and 30-60 wt% of a flavoring agent; wherein these weights are calculated based on dry weight.

[0164] In some embodiments, the aerosol forming material can form 60% by weight of the material. For example, a component formed from lyocell fibers 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.

[0165] In some embodiments, the component may include nicotine. The component may contain nicotine, neutralized at a ratio of up to 5% using benzoic acid in a 1:1 ratio. In some embodiments, a combination of levulinic acid and benzoic acid may be used.

[0166] In some further embodiments, the amorphous solid comprises: an aerosol-forming material in an amount of about 40-80 wt% of the amorphous solid; a gelling agent and optional filler (i.e., in some embodiments, the filler is present in the amorphous solid, and in other embodiments, the filler is not present in the amorphous solid), wherein the amount of the gelling agent and filler together is from about 10 wt% to 60 wt% of the amorphous solid (i.e., 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 a flavoring agent in an amount of up to about 20 wt% of the amorphous solid (i.e., the amorphous solid contains ≤20 wt% active substance).

[0167] 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.

[0168] 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.

[0169] 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.

[0170] Suitably, the amorphous solid may comprise from 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 on a dry weight basis). For example, the amorphous solid 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.

[0171] 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.

[0172] 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), gums, 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 a calcium-crosslinked alginate and / or a calcium-crosslinked pectin.

[0173] The cellulose gelling agent may 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.

[0174] 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.

[0175] In some embodiments, the gelling agent comprises / 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.

[0176] 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 embodiments, the ratio of alginate to pectin is about 2:1 to 8:1, or about 3:1 to 6:1, or about 4:1.

[0177] In some embodiments, the amorphous solid comprises a filler in an amount from 1 to 30 wt%, for example, 5 to 25 wt%, or 10 to 20 wt% of the amorphous solid. In embodiments, the amorphous solid comprises a filler in an amount greater than 1 wt%, 5 wt%, or 8 wt% of the amorphous solid. In embodiments, the amorphous solid comprises a 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 amorphous solid. In other embodiments, the amorphous solid does not contain filler.

[0178] In one embodiment, the amorphous solid comprises a gelling agent and a filler, totaling an amount 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 embodiment, the combined amount of the gelling agent and filler 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 embodiment, the amorphous solid comprises a gelling agent and a filler, collectively measured as 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.

[0179] The filler (if present) may include one or more inorganic filler 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 filler may also include one or more organic filler materials, such as wood pulp, cellulose, and cellulose derivatives. In certain cases, the amorphous solid may not contain calcium carbonate, for example, chalk.

[0180] In some embodiments that include fillers, the fillers may be fibrous. For example, the fillers may be fibrous organic fillers, such as wood pulp, cellulose, or cellulose derivatives. Without being bound by theory, it is believed that including fibrous fillers in amorphous solids can increase the tensile strength of the material.

[0181] In some embodiments, the amorphous solid does not contain tobacco fibers. In certain embodiments, the amorphous solid does not include fibrous materials.

[0182] In some embodiments, the amorphous solid may comprise from 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 25 wt% of aerosol-forming material (all on a dry weight basis). For example, the amorphous solid may comprise 0.5-40 wt%, 3-35 wt%, or 10-25 wt% of aerosol-forming material.

[0183] Aerosol forming materials 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.

[0184] 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.

[0185] In some cases, the aerosol-forming material includes one or more compounds selected from erythritol, propylene glycol, glycerol, triacetyl, sorbitol, and xylitol. Including triacetylglycerol can reduce the perceived harshness of the generated aerosol. In some cases, the aerosol-forming material contains glycerol, is substantially composed of glycerol, or is composed of glycerol.

[0186] The amorphous solid material may include a flame-retardant salt. The flame-retardant salt used herein is a compound composed of ionic components of cations and anions. The salts used herein are those whose anions and / or cations can effectively delay combustion. In some embodiments, the salt is an inorganic salt.

[0187] 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.

[0188] 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.

[0189] In some embodiments, the salt can be 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.

[0190] In some embodiments, the salt has a carboxylic acid anion. For example, the salt may 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.

[0191] In other embodiments, the salt has anion selected from the following: borate, carbonate, phosphate, sulfate, or aminosulfonate.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] Depending on the desired combustion retardancy or other physical properties, 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.

[0196] 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, and may be polar or non-polar, depending on its suitable application.

[0197] The liquid carrier or 37 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.

[0198] 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.

[0199] In some embodiments, the described component 2 can be used for aerosol supply articles, and in some cases, non-flammable 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% of the aerosol forming material.

[0200] 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, the 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.

[0201] In some embodiments, the active substance may include or be derived from one or more plants or their components, derivatives, or extracts. The term "plant-based" 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 particles, granules, pellets, fragments, strips, flakes, etc. Examples of such plants can be found in the list disclosed below.

[0202] 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.

[0203] 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 materials.

[0204] See now 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, which is used in an aerosol supply device 30. The component 2 for the aerosol supply article 3 can be used in a non-flammable aerosol supply device 30. Component 2 includes 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.

[0205] 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 the features and components of the aforementioned component 2 can be incorporated into component 2 of this aspect, and vice versa.

[0206] 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 forming paper 24 can include oil-resistant forming paper. However, in other embodiments, the aerosol modifier release component 40 can be provided in other forms, such as injected into the body of the material 1 of the component 2 or disposed on a cord (e.g., a cord carrying a fragrance or other aerosol modifier), which can also be arranged within the body of the material 1 of the component 2.

[0207] The aerosol modifier release component 40 can be a capsule 41. The capsule 41 can be a breakable capsule. For example, the breakable capsule 41 can have a solid, fragile shell 42 surrounding the liquid payload 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.

[0208] 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.

[0209] 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 payload 42.

[0210] 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 fragrance or other reagent, which may be any of the fragrances or aerosol modifiers described herein. The shell 42 of capsule 41 may be broken by a user to release the fragrance or other reagent into the material 1 forming the body of component 2.

[0211] In this embodiment, capsule 41 may also be substantially 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.

[0212] 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.

[0213] 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.

[0214] 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 payload. Typically, the capsule 41 breaks immediately before use, but the user may choose when to release the aerosol modifier. The term "breakable capsule" refers to capsule 41, in which the shell 42 can be broken by pressure to release the liquid payload 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 payload 43 within the core of capsule 41.

[0215] 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.

[0216] 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 moisture exceeding a predetermined threshold is applied.

[0217] 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.

[0218] In some embodiments, the described component 2 can be used in the non-flammable aerosol supply article 3, such as Figure 3 As generally 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.

[0219] 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 modifier release components 40.

[0220] See now Figure 7 A 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.

[0221] Figure 6 The material 71 of the present aspect of the invention shown is similar to Figures 1 to 5The component 2 of the previously described aspect of material 1 shown is hereby omitted in its detailed description. Furthermore, similar features and components will retain their terminology 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.

[0222] In some embodiments, the material 71 of the present invention may be a nonwoven sheet comprising a plurality of regenerated cellulose fibers 5, as described above. 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 fibers 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.

[0223] 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.

[0224] 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 material and non-paper material. For example, at least one of the plurality of substrate sheets 72, 73 may be formed of aerosol-generating material, such as, but not limited to, tobacco material, plant material, amorphous solid material, or charcoal paper. In some embodiments, one or more substrate sheets 73 of non-regenerated cellulose material and non-paper material may be located between the outer substrate sheets 72, 74 of regenerated cellulose material and / or paper material 72, 74.

[0225] 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.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] In some embodiments, at least one or more portions of the sheet material may be treated with aerosol modifiers (such as flavoring agents), adsorbents (such as charcoal pellets), aerosol-forming materials 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, See now Figure 8 The diagram shows a component 75 for the aerosol supply article 3, such as... Figure 3 As shown. Component 2 is formed of the previously described material 71. Component 2 includes a plurality of substrates 72, 73, 74 aggregated into a generally prismatic shape. This shape may be generally cylindrical. At least one of the plurality of substrates 72, 73, 74 is formed of regenerated cellulose or paper.

[0230] 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 more uniformly. This is due to the lower strength of individual substrate sheets 72, 73, 74, making 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 dimensions of the channels 76, i.e., the gaps between the folds of material 71.

[0231] This reduction in the variability of channel 76 decreases the likelihood that the path through component 75 has 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.

[0232] 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 substrates 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 substrates 72, 73, 74 is formed of regenerated cellulose or paper.

[0233] See now 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-flammable 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.

[0234] An annular material body 54 may form the outer portion 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 portion 54 may extend longitudinally and around the core portion 53. The outer portion 54 is formed of material 1, which comprises a plurality of fibers 5 formed of regenerated cellulose.

[0235] Figure 9 The component 52 of the present aspect of the invention shown is similar to Figures 1 to 7 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 previously described component 2 can be incorporated into component 52 of this aspect, and vice versa.

[0236] The core portion 53 of component 52 may extend longitudinally along the length of the longitudinal axis X of component 52. In this embodiment, the core portion 53 may extend the length of component 52. The outer section 54 may extend longitudinally along the length of the longitudinal axis X of component 52. In this embodiment, the outer portion 54 may extend the length of component 52. In some embodiments, component 2 may have a length in the range of about 4 mm to about 12 mm. In some embodiments, component 2 may have a length in the range of about 6 mm to about 8 mm.

[0237] 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.

[0238] The outer portion 54 may surround the core portion 53. Therefore, the core portion 53 may be located radially inside the outer portion 54. The outer portion 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 portion 54 of the component 52. The material 1 forming the outer portion 54 of the component 52 may be a nonwoven sheet material 1 with or without longitudinal slits and having any of the features of the previously discussed embodiments.

[0239] In some embodiments, the core portion 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 fiber, viscose, rayon, viscose rayon, cuprammonium fiber, and modal fiber. The core portion 53 may take the form of a hollow tubular element 62. That is, the material forming the core portion 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 portion 53.

[0240] 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.

[0241] In this embodiment, the core portion 53 and the outer portion 54 of component 52 can be formed coaxially. That is, the longitudinal axis extending through the center of the core portion 53 of component 52 can coincide with the longitudinal axis extending through the center of the outer portion 54 of component 52.

[0242] 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.

[0243] In some embodiments, the core portion 53 may be formed solely of the cavity 64. That is, the core portion 53 may be formed of the cavity 64 defined by the inner surface of the annular outer portion 54, and the hollow tubular element 62 may be omitted. More specifically, the core portion 53 may not be formed of the first material, but may instead be formed of a material not present in the outer portion 54.

[0244] In some embodiments, the annular material body 54 may also be surrounded by a molding paper. The molding paper may have a weight greater than 50 gsm or greater than 60 gsm.

[0245] 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%.

[0246] In some embodiments, the inner circumferential surface of component 52 may include at least a partially amorphous solid material layer, as previously described. Partial or complete layers may be applied to the inner circumferential surface of the outer portion 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 portion 53.

[0247] 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 inlet section of a filter element in a product, 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 generating component, such as Figure 12 As shown.

[0248] In some embodiments, the annular material body 54 forming component 52 may comprise a plurality of fibers 5 formed of regenerated cellulose and an adhesive, as previously described herein. The annular material body 54 of regenerated cellulose fibers and adhesive may have a density of approximately 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 material body 54 of regenerated cellulose fibers and adhesive can be in the range of about 75% to about 98% for unwound materials, and in the range of about 85% to about 99% for wound materials. The wrapping material surrounding the ring-shaped material body 54 can have a weight greater than about 60 gsm.

[0249] 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.

[0250] See Figure 10 A cross-sectional view of an aerosol supply article 10' is shown. 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 opening 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 as described above. Figures 1 to 8 Component 2 as described in any of the above. Alternatively, the first segment can be formed from a known filter segment. Component 52 can be as described regarding Figure 9 The component described.

[0251] See 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 opening 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 segment. The second component 2 may be as described above. Figures 1 to 8Component 2 as described in any of the above. Alternatively, the second segment may be formed from a known filter segment.

[0252] See Figure 12 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 22 includes components as shown in the diagram. 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 generating 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).

[0253] See now Figure 13 The diagram shows a perspective view of an aerosol supply article 83 comprising 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 comprising a body of material 1, the body of which comprises a plurality of fibers 5 comprising regenerated cellulose. The body of material 1 further comprises an adsorbent material 84. The adsorbent material 84 may comprise at least one of carbon, silica, and CR20.

[0254] Figure 13 The components 91, 92 of the present aspect of the invention shown are similar to Figures 1 to 9 The components 2 and 52 of the previously described aspects are shown, and therefore their detailed descriptions will be omitted here. Furthermore, similar features and components will retain their terminology and reference numerals. It will also be understood that the features and components of the previously described components 2 and 52 may be incorporated into components 91 and 92 of this aspect, and vice versa.

[0255] Figure 13 The aerosol supply article 83 shown may be of a conventional, extended specification, i.e., having a length in the range of about 75 mm to about 91 mm and a circumference in the range of 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 filter 88 via a fitting material 89.

[0256] The filter 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 inlet end of the filter 88 and may be enclosed in a first forming paper 93.

[0257] The second section 92 may be generally identical to components 2 and 52 described previously. The second section 92 may be located at the aerosol-generating material end of the filter 88. The second section 92 may comprise absorbent material in the form of a plurality of regenerated cellulose fibers 5, as previously described, having adsorbent material 84 dispersed therein. The second section 92 may be encased in a second forming paper 94.

[0258] 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.

[0259] The second section 92 may have an adsorbent material 84 of approximately 12 mg per millimeter length. The second section 92 may also have an absorbent material, i.e., fibers of the regenerated cellulose 5, of approximately 4 mg per millimeter length. However, in alternative embodiments, the amount of adsorbent material 84 may be any one of the following ranges: 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 absorbent material (i.e., fibers of the regenerated cellulose 5) may be approximately 1.5 mg to approximately 8 mg per millimeter 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 regular-format filter 88, i.e., having a circumference of approximately 23 mm to 25 mm.

[0260] 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.

[0261] The increase in pressure drop and / or hardness percentage caused by the increase in the adsorbed dose per mm in component 92 of filter 88 can be offset by a decrease in the amount of adsorbent (i.e., the fiber of regenerated cellulose 5) 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 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 products 83, at mg, C w The amount of adsorbent material 84 in the / mm length gauge and the amount of conventional aerosol supply product 83, in mg, T w The amount of adsorbent material (i.e., fibers of regenerated cellulose 5) for the / mm length gauge can be determined according to the following range: 10≤(C w +T w ≤20, These values ​​enable component 92 of filter 88 to exhibit appropriate filter pressure drop and hardness levels, as discussed earlier here.

[0262] If, for a regularly circumferentially oriented aerosol supply product 83, the amount of adsorbent material 84, expressed in mg / mm length, falls 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 regular circumferential aerosols, the advantages can also be achieved in 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 ≤20.

[0263] In addition to the selected adsorbent material 84 falling within the above range and the weight absorbed per mm, the adsorbent material 84 and the weight absorbed C w Tw At least one of the levels may be greater than the minimum level. For example, in some embodiments of the invention, the absorbent level may 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 may be equal to or greater than 6 mg / mm. For a regular circumferential aerosol supply article 84, both minimum levels are about 23 mm to about 25 mm.

[0264] The above scope can also be applied to particulate additives other than adsorbents, such as certain flavorings.

[0265] The second section 92 can be manufactured using filter manufacturing equipment, such as the Turmalin equipment from Hauni Maschinenbau AG in Germany.

[0266] 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 for regular circumferential 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 forming paper and / or a more rigid tipping material surrounding the component. For example, the 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 forming paper and / or tipping material can be used.

[0267] Known filters (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 in a regular form to keep 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 triple filter must generally be used, which has cellulose acetate tow segments at the inlet end and the 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 media that allows for increased additive loading without causing excessive pressure drop and without removing regenerated cellulose fibers.

[0268] The inventors have recognized that by using randomly oriented discrete short-length regenerated cellulose fibers to form a component 82, such as a filter section 92, manufactured using filter manufacturing equipment (such as Turmalin), and by selecting the amount of adsorbent material 84 to be in the range of about 6 mg to about 16 mg per mm on average, and the amount of absorbent (i.e., the fibers of regenerated cellulose) to be about 1.5 mg to about 8 mg / mm on average (or within other ranges and limitations previously outlined), an improved filter component 92 can be provided for a regular circumferential aerosol supply article 83, while maintaining acceptable pressure drop and filter stiffness parameters.

[0269] Reference Figure 14 This is a schematic diagram of a component manufacturing apparatus 100 (such as a Turmalin apparatus) for manufacturing filters. The components formed in the component manufacturing apparatus 100 can be used as filter sections. (See reference...) Figure 14 Multiple regenerated cellulose fiber sources 101 are supplied to a filter manufacturing apparatus comprising multiple modules 102-106. Feeder module 102 receives the supply of regenerated cellulose fibers 5, which, in embodiments supplying regenerated cellulose fiber tows to apparatus 100, are fed from the supply into a cutter and randomizer 23. The cutter and randomizer 23 can cut the regenerated cellulose fibers 5 into short fiber lengths as previously described. In embodiments supplying material 1 comprising multiple hydroentangled or wet-laid regenerated cellulose fibers 5 to apparatus 100, the cutter and randomizer 23 may be omitted. Filter belt machine 104 includes a vacuum belt on which the regenerated cellulose fibers 5 are disposed. This is fed into a rod-forming unit 105 for forming the regenerated cellulose fiber belt 5 into rods wrapped with forming paper. Finally, a component cutter 106 is used to cut the rods into components of desired lengths.

[0270] The filter belt 104 may include a carding unit and multiple hoppers. The carding unit dispenses material 1 onto the vacuum belt, and the multiple hoppers are used to apply additives, such as granules or additional fibers. A return system may also be present, which, if desired, can be used to feed a third additive into the regenerated cellulose fiber belt 5. Alternatively, the return system may be used to feed any loose, cut-off filter material back to the feeder module 102 to reduce waste. The filter belt machine 104 may include a metering roller that is adjustable to allow control of the additive loading and ensure the uniformity of the regenerated cellulose fiber belt. The filter belt 24 may also include a jet inserter for allowing liquids, such as flavoring agents, to be injected directly into the component 82.

[0271] In use, the Turmalin device 100 operates as follows: The feeder module 102 supplies the regenerated cellulose fiber bundles 5 to the cutter and auxiliary device 103. When using material 1 as described above, the cutter and auxiliary device 103 can be omitted. The regenerated cellulose fibers 5 are transferred to the carding unit of the filter belt 104, from which they are drawn onto the vacuum belt. Additives are fed into the airflow carrying the regenerated cellulose fibers 5, and the bar maker 25 forms the belt into a continuous section 92, which is bound by filter forming paper. The segment cutter 106 cuts the continuous section containing the regenerated cellulose fibers 5 into segments of the desired length.

[0272] 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.

[0273] 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), carbonaceous 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 inhaled through component 84 may be used, such as flavoring agents, for example menthol crystals, or humectant particles.

[0274] Filters comprising randomly oriented discrete cellulose acetate fibers are previously known to be manufactured. However, similar to conventional cellulose acetate tow filters, their manufacturing techniques may also require the use of plasticizers, such as triacetin, to bind the randomly oriented fibers into five strong structures. 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 can induce mechanical bonding within the cut fibers, rendering the need for plasticizers obsolete. This eliminates any undesirable effects caused by the use of products such as triacetin.

[0275] In addition to the advantages mentioned above, the inventors have recognized that the Turmalin device or similar apparatus enables various component designs that provide additional improvements and advantages.

[0276] See now Figure 15A 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 herein and previously described. The first section 91 may be as previously referred to. Figures 2 to 13 The section 2 described in the text contains regenerated cellulose fibers 5.

[0277] The second section 92 may include a first absorbent material 113 and a second absorbent material 114 encased in a second 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.

[0278] The second section 92 can be manufactured using the Turmalin apparatus 100. The second section 92 can be manufactured by supplying a first absorbent material 113 to the feeder 102 and by adding a second absorbent material 114 via one of the additive hoppers in the filter belt machine 104. Alternatively, the first and second absorbent materials 113, 114 can each be supplied to the feeder 102 of the apparatus 100.

[0279] 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.

[0280] 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. These nanofibers can be added, for example, when additives are loaded through one or more hoppers in the filter belt conveyor 104. Figure 14 In the filter of the device, nanofibers are metered and supplied to the airflow within the filter belt machine 104.

[0281] Figure 16 A schematic diagram of an aerosol supply article 111 is shown, the aerosol supply article having a component 92 including nanofibers 115 carrying additives, the additives being used to enhance or enable at least one component to reduce the amount of mainstream aerosol drawn through the aerosol supply article 111 during use. Figure 16The 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.

[0282] 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 catalytic agents, 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 additives to the plurality of fibers 5 of regenerated cellulose using the previously described apparatus 100.

[0283] The nanofibers 115 can have any suitable length for inclusion in the component 92, such as between 1 mm and 15 mm, or from 5 mm to 12 mm. The diameter of the nanofibers 115 used can be from 25 nm to 900 nm, or from 50 nm to 500 nm, or from 100 nm to 300 nm.

[0284] See now Figure 17 A schematic diagram of an aerosol supply article 111 comprising a plurality of regenerated cellulose fibers 5 having lines 116 extending therethrough is shown. Figure 17 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.

[0285] The thread 116 can be used as a carrier to add fragrance to component 82. A thread insertion device (not shown) can be installed in the central portion of the filter vacuum belt, wherein the thread insertion needle carries the thread into the axial region of component 82 as component 82 is formed. The embodiments described herein involving the insertion of thread 116 into component 82 are particularly advantageous in thin and ultra-thin formats (i.e., below 22 mm). Thread 11 can extend axially through the second segment 92.

[0286] See now Figure 18 A schematic diagram is shown of an aerosol supply article 111 comprising a plurality of regenerated cellulose fibers 5 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 13The 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.

[0287] 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 flavor). In some embodiments, capsule 117 may be a microcapsule or other encapsulation material.

[0288] In a manner similar to that described regarding carbon loading, it is possible to add such materials at higher levels to deliver more flavor. Capsules (whether larger capsules, such as those with a diameter between 3 mm and 8 mm, microcapsules, or other encapsulating materials) can be pushed into multiple regenerated cellulose fibers 5 in a 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 the filter belt machine 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 the filter belt machine 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 rod 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.

[0289] An aerosol modifier release component for a flavoring agent, encapsulated in the form of capsule 117, may be arranged within the second section 92. (See brief description) Figure 19 A schematic diagram is shown of an aerosol supply article 83 comprising a plurality of regenerated cellulose fibers 5, wherein the regenerated cellulose fibers have aerosol modifier release components 117 in the form of microcapsules disposed therein. An aerosol modifier release component having an encapsulated fragrance agent, in this embodiment in the form of microcapsules 118, may be arranged within a second section 92.

[0290] Reference Figure 20 A schematic diagram of an aerosol supply article 83 comprising a plurality of regenerated cellulose fibers 5 having shredded material 119 disposed therein is shown. 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.

[0291] In addition to the encapsulated flavoring agent, other forms of flavor additives can be added to the filter containing multiple regenerated cellulose fibers 5. For example, flavor additives can be added in botanical form, such as mint or tobacco leaves or other plant leaves, plant seeds, or plant peels, as previously described herein and outlined in more detail below. Such additives can be added to the additive hopper in the belt-forming machine of the device 100 and thus metered into the regenerated cellulose fiber airflow during filter belt formation or component formation. In some embodiments, because plasticizers are not used, the release of flavor from the botanical additives can be enhanced.

[0292] In some embodiments, the shredded material 119 may be contained within a material formed from a plurality of fibers 5 comprising regenerated cellulose. Such flake material may include flake material 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 flake material 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.

[0293] Shredded material 119 may include materials formed from fibers of the following: 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.

[0294] The inventors have 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-crewed 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.

[0295] 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 can be arranged to feed two raw material ropes into the cutter and the accompanying machine 23. Thus, the number of processing steps is reduced by straightening the material as a tow instead of first converting it into sheet material.

[0296] 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.

[0297] 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 belt machine 104.

[0298] 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.

[0299] 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.

[0300] 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 fibers, while the second plurality of fibers 123 may be formed from, for example, a different one of viscose, rayon, viscose rayon, and lyocell fibers.

[0301] 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.
