Definitions

  • the present disclosure relates to a filter to which a binder with improved functionality is applied and a smoking article including the same.
  • Lyocell contains cellulose as its main component, and a plasticizer harmless to the human body is hardly present in lyocell, unlike in cellulose acetate (CA). For this reason, a binder solution should be used to produce a filter using lyocell and impart a certain level of hardness or higher to the filter.
  • TEC triethyl citrate
  • TA triacetin
  • the present disclosure is directed to providing a lyocell filter for smoking articles that is produced by homogeneously mixing a binder and materials such as triethyl citrate (TEC) and/or triacetin (TA) with lyocell fibers and a smoking article including the lyocell filter.
  • TEC triethyl citrate
  • TA triacetin
  • One aspect of the present disclosure provides a smoking article filter including lyocell tow including a plurality of lyocell fibers, a phenolic functional material, and a binder.
  • a smoking article including a tobacco medium portion and a filter portion, wherein the filter portion includes lyocell tow including a plurality of lyocell fibers, a phenolic functional material, an amphoteric binder, and an alcohol, the phenolic functional material is one or more selected from the group consisting of triethyl citrate (TEC) and triacetin (TA), and the amphoteric binder is one or more selected from the group consisting of a cellulose-based binder and a vinyl-based binder.
  • TEC triethyl citrate
  • TA triacetin
  • Still another aspect of the present disclosure provides a method of producing a smoking article filter, the method including: a) preparing lyocell tow including a bundle of a plurality of lyocell fibers; b) mixing an amphoteric binder and an alcohol and then mixing a phenolic functional material therewith; and c) dispersing a solution, which is obtained by the mixing, in the lyocell tow, wherein the phenolic functional material is one or more selected from the group consisting of triethyl citrate (TEC) and triacetin (TA), the amphoteric binder is one or more selected from the group consisting of a cellulose-based binder and a vinyl-based binder, and the alcohol is propylene glycol (PG).
  • TEC triethyl citrate
  • TA triacetin
  • the amphoteric binder is one or more selected from the group consisting of a cellulose-based binder and a vinyl-based binder
  • the alcohol is propylene glycol
  • a lyocell filter in which materials such as triethyl citrate (TEC) and/or triacetin (TA), which are fat-soluble, are more homogeneously mixed, and in this way, there is an advantage that components such as phenols that are present in cigarette smoke can be more effectively removed during smoking. Also, an eco-friendly filter can be produced using lyocell tow.
  • materials such as triethyl citrate (TEC) and/or triacetin (TA), which are fat-soluble
  • first, second, A, B, (a), and (b) may be used. Such terms are only for distinguishing one component from another component, and the essence, order, sequence, or the like of the corresponding component is not limited by the terms.
  • a component including a common function with a component included in any one embodiment will be described using the same name in another embodiment. Unless the context clearly indicates otherwise, description made in any one embodiment may apply to another embodiment and detailed description will be omitted in a repeated range.
  • a "smoking article” may refer to anything capable of generating an aerosol, such as tobacco (cigarette) and cigars.
  • the smoking article may include an aerosol-generating material or an aerosol-forming substrate.
  • the smoking article may include a solid material based on tobacco raw materials, such as reconstituted tobacco leaves, cut tobacco leaves, and reconstituted tobacco.
  • a smoking material may include a volatile compound.
  • upstream or upstream direction refers to a direction moving away from an oral region of a user smoking a smoking article 1
  • downstream or “downstream direction” refers to a direction approaching the oral region of the user smoking the smoking article 1.
  • a tobacco material portion 10 is disposed upstream or in an upstream direction of a cigarette filter portion 20.
  • the smoking article 1 is a combustion-type cigarette
  • the present disclosure is not limited thereto, and the smoking article 1 may also be a heating-type cigarette or the like that is used together with an aerosol generation device (not illustrated) such as an electronic cigarette device.
  • One embodiment of the present disclosure provides a smoking article filter including lyocell tow including a plurality of lyocell fibers, the smoking article filter including a binder solution containing a phenolic functional material and a binder.
  • the phenolic functional material corresponds to a material that can specifically reduce phenols generated during smoking.
  • the phenolic functional material may be triethyl citrate (TEC) or triacetin (TA) or may be both.
  • the content of the TEC or TA may be 20 to 50 wt%. In a case in which the content is less than 20 wt%, an effect of reducing phenols may be weakened, and in a case in which the content exceeds 50 wt%, the adhesive strength of the binder solution may significantly decrease, and it may be difficult to implement an appropriate filter hardness.
  • the type of binder included in the smoking article filter may partially differ according to a method by which the filter is produced, and the binder may correspond to a hydrophilic binder, and/or an amphoteric binder that is both water-soluble and fat-soluble.
  • the smoking article filter includes a hydrophilic binder
  • the hydrophilic binder and the phenolic functional material such as TEC or TA, which is fat-soluble, cannot be easily mixed, and thus a phenomenon in which layers of the solution are separated occurs. Therefore, in this case, it is desirable to additionally add an emulsifier when producing the filter, and accordingly, the produced smoking article filter further includes an emulsifier.
  • the type of emulsifier may be an emulsifier for food, and as a specific example, the emulsifier may correspond to a monoglyceride, diglyceride, and/or triglyceride.
  • the smoking article filter includes an amphoteric binder
  • an eco-friendly aqueous solution and the fat-soluble phenolic functional material such as TEC or TA, which are used in producing the lyocell filter
  • the phenolic functional material can be homogeneously dispersed in the lyocell tow, and it is possible to effectively reduce components such as phenols that are present in cigarette smoke during smoking.
  • Types of amphoteric binder may include a cellulose-based binder and/or a vinyl-based binder.
  • the cellulose-based binder may be one or more selected from the group consisting of hydroxypropyl methylcellulose (HPMC), ethyl cellulose (EC), methyl cellulose (MC), and carboxymethyl cellulose (CMC)
  • the vinyl-based binder may be one or more selected from the group consisting of polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), and ethylene vinyl acetate (EVAc).
  • the vinyl-based binder among the types of amphoteric binder may be more desirable, and the vinyl-based binder may be PVP.
  • the viscosity is low when mixed with the fat-soluble phenolic functional material, and thus the fat-soluble phenolic functional material may be more homogeneously mixed. Further, even when producing the smoking article filter, there is an advantageous effect that it is possible to easily produce a filter in which the phenolic functional material is homogeneously dispersed in the lyocell tow.
  • an alcohol may be further included and mixed to prevent the growth of microorganisms and fungi in the binder solution.
  • Types of alcohol may include a polyhydric alcohol, a monohydric alcohol such as ethyl alcohol, or a mixture thereof.
  • Propylene glycol (PG), which is a polyhydric alcohol, may be included as the alcohol.
  • PG serves as a release agent, and a phenomenon in which the lyocell tow is adhered and stuck to the rolls of filter equipment is reduced. As a result, the efficiency of the filter production process is increased.
  • ethyl alcohol is used as the monohydric alcohol
  • 5 to 10 wt% thereof may be used
  • PG is used as the polyhydric alcohol
  • 20 to 50 wt% thereof may be used.
  • the smoking article filter may further include a capsule carrying a flavor therein or further include a moisturizer or the like.
  • the smoking article filter includes the flavor-carrying capsule
  • the moisturizer due to effects of providing various flavor experiences and masking an unpleasant smell, the smoker's satisfaction may be increased.
  • vapor production may be more effectively increased as compared to the conventional smoking articles.
  • a smoking article including a tobacco medium portion and a filter portion, the smoking article including lyocell tow including a plurality of lyocell fibers, a phenolic functional material, an amphoteric binder, and an alcohol, wherein the phenolic functional material is one or more selected from the group consisting of triethyl citrate (TEC) and triacetin (TA), and the amphoteric binder is one or more selected from the group consisting of a cellulose-based binder and a vinyl-based binder.
  • TEC triethyl citrate
  • TA triacetin
  • amphoteric binder and the alcohol are substantially the same as the types of amphoteric binder and alcohol included in the smoking article filter, which have been described above, and polyvinylpyrrolidone (PVP) may be included as the amphoteric binder while propylene glycol (PG) is included as the alcohol.
  • PVP polyvinylpyrrolidone
  • PG propylene glycol
  • the tobacco medium portion typically includes a tobacco material including nicotine such as tobacco leaves and may further include an excipient such as a binder or other additives.
  • a tobacco medium included in the tobacco medium portion of the present disclosure may be produced in the form of granules including the tobacco material, the excipient, and the like.
  • the tobacco material is a material forming an aerosol-generating substrate and may be pieces of tobacco leaves, tobacco stems, tobacco powder generated while processing tobacco, and/or strips of tobacco leaves.
  • the tobacco leaves may be at least one or more selected from bright tobacco leaves, burley tobacco leaves, oriental tobacco leaves, cigar tobacco leaves, and toasted tobacco leaves, but the present disclosure is not limited thereto.
  • the filter portion of the smoking article according to one embodiment of the present disclosure may be divided into two or more segments.
  • the filter portion may be divided into a first filter portion, a second filter portion, and the like, and as long as one of the two or more segments corresponds to the smoking article filter according to one embodiment of the present disclosure regardless of where the one segment is disposed, the filter portion may be included within the scope of the present disclosure.
  • the smoking article may include, in addition to the tobacco medium portion and the filter portion, a wrapper configured to surround the constituent portions, and the wrapper may be produced using common filter wrapping paper. Also, one or more perforations may be selectively formed in a circumferential direction in a tipping wrapper configured to combine the tobacco medium portion and the filter portion in order to allow outside air to enter or an internal gas to exit. In this way, there are advantageous effects that an air dilution rate of a cigarette can be increased, and the amount of delivered mainstream smoke components can be controlled.
  • lyocell tow in which a tow fiber bundle has a size of about 35,000 denier was produced.
  • a binder solution which is a mixture of a binder, TEC, and a solvent, was prepared.
  • the binder solution was prepared by adding 10 wt% polyvinylpyrrolidone (PVP) to a 60 wt% solvent (a solvent in which 40 wt% propylene glycol, 10 wt% ethanol, and 10 wt% water are mixed) and 30 wt% TEC based on the entire weight of the binder solution.
  • PVP polyvinylpyrrolidone
  • the prepared binder solution was sprayed on the lyocell tow through brush spraying.
  • the binder solution was sprayed at 10 or 15 wt% based on the weight of the lyocell tow to produce the lyocell tow including the binder.
  • the produced lyocell tow was dried and then wrapped with wrapping paper to produce a cigarette filter having an axial length of about 108 mm and a circumference of about 24.20 mm.
  • the inventors of the present disclosure compared differences in viscosity by temperature of PVP which is a vinyl-based binder according to one embodiment of the present disclosure, hydroxypropyl methylcellulose (HPMC) which is a cellulose-based binder, and polyester (refer to Table 1).
  • PVP vinyl-based binder
  • HPMC hydroxypropyl methylcellulose
  • polyester polyester
  • HPMC which is a cellulose-based binder and PVP which is a vinyl-based binder both correspond to amphoteric binders, and thus both of the binders may be mixed with TEC which is fat-soluble.
  • TEC which is fat-soluble.
  • HPMC had a higher viscosity during dissolution than PVP and was not homogeneously dispersed in the filter production process, which caused the tow to be adhered to and rolled around a mechanical roll. As a result, problems such as breakage of the tow occurred.
  • PVP had a lower viscosity than HPMC and thus had advantages that a problem did not occur in the filter production process, and the TEC material could be homogeneously dispersed in the lyocell tow.
  • polyester could not be homogeneously mixed with TEC which is a phenolic functional material and thus had a limitation in that a surfactant or an emulsifier should be used to homogeneously disperse polyester.
  • TEC is a phenolic functional material
  • the viscosity rather increases.
  • a polyester binder, water, propylene glycol (PG), and ethyl alcohol (EtOH) were mixed together to prepare a polyester binder solution, and a PVP binder, water, PG, EtOH, and TEC were mixed together to prepare a PVP binder solution.
  • a PVP binder, water, PG, EtOH, and TEC were mixed together to prepare a PVP binder solution.
  • TEC ethyl alcohol
  • TEC ethyl alcohol
  • Lyocell filters to which the two different binder solutions were applied were used to produce cigarettes, the amounts of phenol in the smoke of the cigarettes were measured and compared, and the results are shown in Table 2 below.
  • the phenol reduction effect is about 30% greater when the PVP binder solution is applied to the lyocell filter.
