Description

CIGARETTE FILTER AND APPARATUS AND METHOD FOR MANUFACTURING THE SAME

A tobacco filter and an apparatus and method for manufacturing the same are disclosed. More particularly, the present invention relates to a cigarette filter capable of reducing paper wastage by containing bamboo fibers in a filter paper, and capable of reducing deviation in suction resistance by application of dry crimping and improving manufacturing workability, And a method are disclosed.

As is generally known, some cigarette smoke generated during the smoking process contains substances that affect the human body, including tar and nicotine. Therefore, it is important to remove the ingredients that affect the human body contained in the smoke, and the filter is attached to the cigarette.

These filters are generally wrapped in a filter wrapper, and each tip of the cigarette and filter is wrapped by a tip paper. Therefore, the smoker puts on the tip paper on which the filter is provided and performs suction operation.

On the other hand, there are many kinds of such filters. For example, an acetate tow filter prepared with an acetate tow, a paper filter made of ordinary paper, and the like are available. Among them, the paper filter is an eco-friendly material and has an advantage of high tar removal ability.

However, in the conventional paper filter, the manufacturing workability is poor, and there is a negative effect on the smoke quality such as paper wastage, low phenol / vapor phase component removal ability, moisture transfer amount reduction, and the like, .

In addition, microfibers are developed in the pulp during the production of filters using paper materials, so that they are subjected to a cleansing process in order to improve the physicochemical properties such as tensile strength and smoke adsorption ability of the paper base paper. May occur.

On the other hand, in the conventional case, the paper filter cloth is manufactured through a wet-type crimping process. The general paper filter is manufactured through a two-step process. The first process is wet-crimping the paper to improve the removal ability of the smoke component and the workability of the filter manufacturing. The second process uses a crimped paper to filter .

In order to prevent the tearing of the paper during the first crimping process, the paper is soaked in water and then softened to be crimped. At this time, the water absorbed by the high temperature needs to be dried again, thus consuming electric energy. In addition, when manufacturing crimped raw paper, it is necessary to absorb the water to the wide paper and crimp it, dry it and then cut the paper with a width suitable for the filter production. Since the paper is crimped at this time, The deviation of the filter suction resistance can be increased.

In addition, since the crimped raw paper is short in length, it is necessary to replace the raw paper at the time of manufacturing the filter.

Hereinafter, configurations and applications according to embodiments of the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE INVENTION The following description is one of many aspects of the claimed invention and the following description forms part of a detailed description of the present invention.

In the following description, well-known functions or constructions are not described in detail for the sake of clarity and conciseness.

1 is a view showing a schematic shape of a cigarette according to an embodiment of the present invention.

As shown therein, the cigarette 100 according to an embodiment of the present invention includes the cigarette filter 110 and the wefts 150. The cigarette filter 110 includes a filter unit 111 connected to the respective wefts 150 to filter the smoke, a filter wrapper 120 surrounding the filter unit 111, a filter wrapper 120, And a tip paper 130 surrounding the rear end region.

In the case of the embodiment of the present invention, unlike the filter paper made of wood pulp, it is made of hollow bamboo fiber, so that it is possible to remarkably reduce paper dust that can be generated in the paper manufacturing process or the crimping process. Hereinafter, And an apparatus and a method for producing the same will be described in detail.

First, the cigarette filter 110 of the present embodiment is made of a filter paper containing bamboo fibers, thereby significantly reducing paper consumption. In order to enhance the physicochemical properties such as the tensile strength and the smoke adsorption capacity of the filter paper, a blanching process is generally performed. In this embodiment, since the bamboo fiber applied as the filter paper has a hollow shape, The amount of material can be reduced. However, since the tar removal ability may be lowered when the bamboo fiber filter raw paper is produced, the filter paper can be manufactured by mixing the general wood fiber and the bamboo fiber.

2 is a graph showing porosity according to the blending ratio of bamboo fibers.

Referring to this, it can be seen that the air permeability is increased when the blending ratio of bamboo fiber and wood fiber (general pulp, Howesound) is increased. That is, the higher the blending ratio of bamboo fiber is, the better the paper shrinkage is. However, when the blending ratio of bamboo fiber is increased, defective dehydration or deterioration of manufacturing workability may occur. Therefore, as shown in Fig. 2, the blending percentage of bamboo fiber may be suitably 50 percent. However, it is not limited to this, and it is natural that the blending percentage of the bamboo fiber can be determined in the range of 10 to 90 percent in the production of the filter paper.

In addition, as a result of the SEM analysis by the type of fiber, the conventional acetate tow filter has a Y-shape and a smooth surface, whereas the wood fiber or bamboo fiber (particularly bamboo fiber) has a relatively developed fine fiber, It is possible to improve the ability to remove particulate matter by diffusion and the like.

As a result of SPME analysis, it was found that the butylated hydroxy toluene material expressing paper wastes in the filter paper of the present example is a conventional filter paper made of ordinary fibers or sulfite pulp, It can be seen that the filter paper of the present embodiment can reduce paper dust.

In the meantime, the filter material of this embodiment can be provided with a crepe by a dry crimping process, rather than a conventional wet crimping process. This will be described with reference to FIG. 3 and FIG.

FIG. 3 is a flow chart illustrating a process for fabricating paper according to dry crimping, and FIG. 4 is a schematic view of a device for dry crimping.

Referring to FIGS. 3 and 4, a process for manufacturing a filter paper by dry-pressing includes a first drying step (S100) by a first dryer (241) having a first temperature and a second drying step A second drying step S200 by the second dryer 242 having a temperature of 2 degrees, a calendar step S300 by a calendar, a reel step S400 by a reel, and a rewinder step S500 by a rewinder .

Referring to FIG. 4, the first and second dryers 241 and 242 have different temperatures. The first dryer 241 is wound on the first dryer 241 with the wrinkle part 250 mounted thereon It is possible to impart wrinkles to the moving filter paper. The first dryer 241 and the second dryer 242 are rotated at different speeds, thereby softening the filter paper, thereby lowering the resistance of the crimping and thus preventing tearing.

As described above, by applying dry crimping to apply wrinkles to the filter paper of this embodiment, the quality deviation can be reduced and the filter manufacturing process can be simplified. In other words, when dry crimping is applied, it is not necessary to wet or dry the filter paper such as a wet-type crimping process, and it is slit to a predetermined width suitable for manufacturing a filter after paper manufacture, The manufacturing process can be shortened, and the length of the paper used for manufacturing the filter can be increased to, for example, more than 5000 meters, thereby improving the filter manufacturing workability.

The following table is a table for analyzing the suction resistance of the filter paper of the present embodiment to which the dry crimping is applied and the conventional filter paper sheets.

As described above, in the case of the cigarette filter of this embodiment, which was manufactured by dry-crimping filter paper containing bamboo fiber, the suction resistance variation was reduced by 26.1 compared to a general paper filter made by wet crimping, , The suction resistance variation can be remarkably reduced when the filter is manufactured by applying the dry crimping method.

On the other hand, the following table is a table comparing filter removability and smoke component transfer amount of the cigarette filter of the present embodiment and the conventional filter.

In Table 2, Tar Removal Efficiency (TRE) is the tar removal efficiency, NRE is the Nicotine Removal Efficiency, and SRE is the Smoke Removal Efficiency.

As shown in Table 2, the tobacco filter of the present embodiment having the filter paper containing the bamboo fiber had a remarkably high tar removing ability and nicotine removing ability as compared with the toe filter, and is similar to the general fiber application filter.

On the other hand, the cigarette filter of the present embodiment has a high ability to remove tar and nicotine as compared with a tow filter, but has a low ability to remove phenolic components, and has high water removing ability, which is an important factor in smoke quality. In particular, phenolic compounds in fumes are a major contributing factor to unpleasant odors and disgusting taste, and such changes in smoke composition can adversely affect tobacco smoke quality when filtered.

Thus, an additive for improving phenol removal ability can be added to the filter paper of this embodiment. In addition, in the case of the filter paper of this embodiment, the water removal ability is also increased. Since the amount of moisture in the smoke is an important factor affecting the taste of the cigarette, moisturizing agent may be applied to the filter paper to increase water retention and increase the moisture transfer amount in the smoke.

Additives or moisturizers may be added by filter paper coating. In this case, 4% of propylene glycol (PG, propylene glycol) and 20% of polyethylene glycol (PEG, polyethylene glycol) can be uniformly treated without loss. The following Table 3 shows this.

However, it is natural that the additive or the moisturizing agent can be added to the filter raw paper by the surface coating, but not limited thereto, and can be added to the filter raw paper by direct injection.

As described above, an additive for improving the phenol removing ability is added to the filter paper of the present embodiment, wherein the additives include polyethylene glycol 200, polyethylene glycol 400, polyethylene glycol 600, triacetin, triethylene glycol diacrylate (triethylene glycol diacrylate) and the like can be applied. In particular, polyethylene glycol or triacetin mixed additive having little odor and low extraction can be applied.

The following table is a table showing the content of phenol components according to the content of polyethylene glycol.

As shown in Table 4, the phenol content in the smoke was decreased in a concentration dependent manner by the treatment with polyethylene glycol. In comparison with the untreated control group, the amount of transfer of phenol was about 40% when treated with 12 mg of polyethylene glycol and about 60% .

On the other hand, as described above, a moisturizing agent for increasing the moisture permeability may be added to the filter paper of the present embodiment, and propylene glycol (PG) may be applied. The following table is a table showing the contents of various components including the moisture migration amount according to the content of propylene glycol.

As shown in Table 5, when 16 mg / tip of propylene glycol is applied to the filter paper, the moisture migration amount can be improved by about 10%. Therefore, the content of propylene glycol added to the filter paper is preferably about 5 to 20 mg / tip.

As described above, since the ability to remove phenol through polyethylene glycol can be increased and the water migration amount can be increased through propylene glycol, polyethylene glycol and propylene glycol can be appropriately mixed and added to the filter paper.

On the other hand, the cigarette filter to which the filter paper of the present embodiment is applied has a weak function of adsorbing the vapor phase component due to the characteristics of the material. In this embodiment, activated carbon may be added to the filter paper. The particle size of the activated carbon added to the filter paper of this embodiment can be adjusted to about 15 to 80 mesh. Therefore, when the filter is manufactured, the pressure of the filter raw paper to press the activated carbon may increase, thereby allowing the activated carbon to penetrate deeper between the raw paper, thereby reducing the amount of activated carbon that is dropped when the filter is cut. That is, the efficiency of introduction of activated carbon into the filter paper can be increased.

Further, in order to increase the efficiency of introduction of the activated carbon into the filter paper, the filter manufacturing apparatus is provided with the suction unit on the opposite side of the apparatus for providing the activated carbon based on the filter paper, so that the charged activated carbon can penetrate deeper into the paper. In addition, an adhesive injection unit, that is, an adhesive injection unit that provides an adhesive agent, that is, the hot melt of the present embodiment, that is, a hot-melt injection unit of the present embodiment is provided in the filter manufacturing apparatus, So that it can be bonded.

In this case, it is possible to add a small amount of activated carbon less than 80mesh, and when the activated carbon is adhered using the hot melt, the plasticizer pore clogging by the plasticizer can be prevented.

Hereinafter, performance analysis of the cigarette filter of this embodiment will be described with reference to the table.

Table 6 is a table for analyzing filter removability when activated carbon is added.

It can be seen from Table 6 that the filter of the present embodiment, which is produced by adding activated carbon to the filter paper containing bamboo fiber, has a tar removal capability of about 13% as compared with a general tow filter to which activated carbon is added.

Table 7 is a table for analyzing the vapor phase transfer amount.

It can be seen from Table 7 that the filter of the present embodiment prepared by adding activated carbon to the filter paper containing bamboo reduces the vapor phase shift amounts of Aledhydes and VOCs by about 10% as compared with a general tow filter containing activated carbon have.

Table 8 shows the results of sensory evaluation.

It can be seen from Table 8 that the filter of the present embodiment, which is produced by adding activated carbon to the filter paper containing bamboo, has reduced hysteresis as compared with the conventional filter made of a paper material, and improves the washability and smoke fullness Can be obtained.

Hereinafter, a filter manufacturing apparatus for manufacturing a cigarette filter according to an embodiment of the present invention will be described.

With this configuration, the filter paper containing the bamboo fiber can be manufactured from a cigarette filter.

First, the raw paper feeder 220, as a portion where the filter paper is wound, is transported along a predetermined path of the paper feed unit 230, .

The additive coating unit 260 can improve the phenol removing ability and the water migration amount of the filter by coating a filter paper having a wrinkle formed by the dry crimping unit 240 with a solvent containing polyethylene glycol and propylene glycol .

Also, when the additive coating unit is attached before the dry-type crimping unit to coat the additive, it is possible to reduce the stiffness generated during the crimping and smoothly perform the crimping.

Meanwhile, in the activated carbon providing unit 270 of the present embodiment, the suction unit 275 is provided on the opposite side of the activated carbon providing unit 270, so that the charging efficiency of the activated carbon to the filter raw paper can be improved.
