Definitions
- the invention relates to tobacco smoke filters or filter elements which are constructed in one piece and contain fibers, filaments or films based on spinnable or film-processable polymers or polymer blends and one or more additives.
- Tobacco smoke filters of the above type are known in the art.
- integrated means that the tobacco smoke filters are of uniform construction in the longitudinal axial direction and can be produced without further limiting filter elements
- Spaced filter elements of conventional filter material provide a confined by a wrapping paper outwardly chamber, which may be filled by additives such as granular activated carbon.
- the filter construction described in EP-AO 014 477 behaves more favorably, in which granular activated carbon is interspersed in a filter element in such a way that an approximately homogeneous distribution of the activated carbon particles in the fibers or filaments which are themselves homogeneously distributed of the filter material is ensured. If by-pass formation can be ruled out in this way, coarse-grained additives are required in order to ensure fixing of the said particles in the tobacco smoke filter. The described disadvantages of the coarse-grained activated carbon are therefore also evident in this filter construction.
- filter cigarettes are attached to their mouthpiece. provided at the end with tobacco smoke filter that captures at least a portion of the combustion products of the cigarette tobacco and thereby prevents the combustion products are inhaled during smoking.
- a tobacco smoke filter should influence the taste of the tobacco smoke so that it is judged by the smoker to be positive.
- the tobacco smoke filter is mixed with a porous, particulate additive which increases the filtration performance of the tobacco smoke filter or of the tobacco smoke filter elements compared to a tobacco smoke filter without particulate additives.
- the porous additives preferably adsorb gaseous combustion products on their inner surface and thus reduce their concentration in the smoke.
- the porous additives preferably adsorb gaseous combustion products on their inner surface and thus reduce their concentration in the smoke.
- the porous additive activated carbon In the most prominent representatives of this type of cigarette filters is used as a porous, particulate additive activated carbon.
- Other such tobacco smoke filters as described, for example, in DE-A-2 658 479, contain oxides, hydroxides and / or hydrated oxides of various metals, such as silicon, aluminum, magnesium, iron and / or titanium.
- Critical to the effectiveness of such porous, particulate additives is their accessibility to the gaseous smoke ingredients. It has thus been shown that, in particular, finely divided porous materials show increased filter performances compared with coarser particles.
- Other disadvantages of the above-mentioned chamber filter can be seen in the fact that they require a lot of effort in their production.
- US-A-3,043,736 and US-A-2,881,770 describe a tobacco smoke filter from a bundle of endless, crimped cellulose acetate filaments which are combined by a wrapping paper into a filter rod, the individual filaments being finely divided Activated carbon are occupied.
- the possible devices for application of the finely particulate additives can be classified into devices a) for applying the additive from a slurry in an aqueous phase or a volatile organic carrier or plasticizer fluid, b) for inflating the small particle additives previously mentioned c) for application from a latex emulsion; and d) for applying the additive by passing a bundle of filaments or filaments previously wetted by adhesive or plasticizer through a fluidized-bed of finely divided activated carbon.
- devices a) for applying the additive from a slurry in an aqueous phase or a volatile organic carrier or plasticizer fluid b) for inflating the small particle additives previously mentioned c) for application from a latex emulsion
- d) for applying the additive by passing a bundle of filaments or filaments previously wetted by adhesive or plasticizer through a fluidized-bed of finely divided activated carbon.
- the tobacco smoke filters manufactured according to the above methods are characterized in that the filaments loaded with additives are preferably oriented longitudinally and mutually bound to one another at randomly distributed contact points by means of the action of an adhesive or plasticizer, so that substantially longitudinally distributed over the filter small spaces between adjacent filaments are created by the flow of tobacco smoke.
- the cited exemplary embodiments illustrate that the tobacco smoke filters thus produced and offset by particulate additives have similarly high tensile resistances as comparative filters without incorporation of particulate additives. Consequently, according to these methods, it is not possible to produce filters which have equally high additive mass and low draw resistances.
- filter filters doped with activated carbon in tobacco smoke filters are used. These include activated carbons of small particle size, which are bound to the paper in the papermaking process.
- a fabric is produced by the manufacturer of the filter material, rolled up on reels and then sent to the processor. The filter or cigarette manufacturer rolls off the material from the reel, forms it into a rod-shaped product, then compresses it transaxially in the format part of the filter rod machine, envelops it with paper and cuts it to the final length of the filter rods.
- the fabric is usually, but not necessarily, crimped before forming into a rod parallel to the direction by a creping device.
- this object is achieved in that a) the additives are present on the surface of the fibers, the filaments or the films, b) the draw resistance of the tobacco smoke filter and the mass of the additives in the tobacco smoke filter the following
- [mg] is the mass of the additives, c) the tobacco smoke filter has channel structure and d) the filter material is in the form of a flat structure.
- the filter material is a flat structure of fibers or filaments .or a film, wherein the planar structure and / or the film are smooth, folded, embossed and / or partially compacted.
- the filter material is made up of a cellulose ester, cellulose esters being in particular cellulose acetate, cellulose butyrate, cellulose losobutyrate, cellulose acetopropionate and / or cellulose propionate.
- a particularly preferred cellulose acetate has a degree of substitution of about 1.5 to 3.0, especially about 2.2 to 2.6, more preferably 2.5. It has proven to be particularly advantageous to use a tobacco smoke filter which is described in WO 01/28369 within the scope of the invention or in its realization.
- the fiber weight (or filament weight / pull ratio S referred to the filament funnel is greater than about 0.7, where the S value is given by the formula
- the fiber weight is at most 10 mg / mm filter length and / or the residual crimp of the filter material does not exceed the value of 1.45, in which case the following formula (III) applies:
- m A is the fiber weight [g]
- G is the total [g / 10 exp 4 xm]
- I is the filter length [mm].
- Optimum residual crimping is between about 1.05 and 1.4, in particular between about 1.1 and 1.3. Furthermore, it is preferred that the fiber weight (or filament weight) / draw resistance ratio S related to the filament titer is at most about 2, in particular between about 0.8 and 1.3.
- the tobacco smoke filter according to the invention when the fiber weight (or filament weight) is at least about 4 mg / mm filter length, in particular between about 5 and 8 mg / mm filter length.
- this should preferably be between about 90 to 95, in particular between about 91 and 93.
- the additives that are essential for the solution of the problem are arranged on the surface of the fibers, the filaments or the films.
- these additives are particulate, in particular have a particle size of less than 300 microns, in particular less than 100 microns. It is particularly preferred if the particle diameter is less than 50 ⁇ m, with a particle size of less than 30 ⁇ m leading to particularly good results.
- the invention is not subject to any significant restriction.
- the suitable additives these preferably being in the form of an adsorbent based on activated carbon, metal oxides, metal hydroxides and / or metal oxide hydrates, in particular those of aluminum, silicon, titanium and / or magnesium is acting.
- the porous additive is additionally mixed with active substances, in particular in the form of antioxidants, flavors and / or antimutagenic substances.
- the introduction of the particulate additives into the tobacco smoke filter according to the invention is not critically limited. Nevertheless, it is preferred that the additives are shaped teilchen ⁇ xed means of a binder on the surface of the filter material fi ⁇ , especially with polyvinyl acetate, polyvinyl alcohol, polyethylene glycol, which ⁇ serlöslichen esters or ethers, starch, starch derivatives and / or Celluloseestern.
- the surface of the fibers, filaments and films can be further optimized as follows:
- the additive located thereon can fulfill the function of a filtration aid, in particular in the form of organic acids, acid carboxylic acid esters, polyphenol and / or porphyrin. derivatives.
- the fibers, filaments and foils of the film material or the fibers, filaments or films constituting the tobacco smoke filters or filter elements may contain further additives in the interior which improve their properties. These are preferably plasticizers, matting agents, pigments and / or stabilizers. Of particular importance is the inclusion of the plasticizer.
- the tobacco smoke filter according to the invention may also contain a photoreactive additive, in particular in the form of finely divided anatase-type titanium dioxide having an average particle size of less than 2 .mu.m.
- the draw resistance of the tobacco smoke filter and the mass of the additives in Ta bacrauchfilter comply with the following formula (I): M ad / Ap 7/8 > 1 mg / daPA (I), wherein Ap [daPA ] is the draw resistance, which is converted to a filter diameter of 7.8 mm Value is used, and M ad [mg] is the mass of the additives. It is particularly preferred if the ratio of M ad / ⁇ p is above 2 mg / daPa, in particular above 3 mg / daPa.
- channel structure of the claimantly constructed tobacco smoke filter or filter elements Another essential feature of the invention is the channel structure of the claimantly constructed tobacco smoke filter or filter elements. It should be noted that in a channel structure, channel-shaped regions of lesser material density extend longitudinally over a substantial portion of the length of the filter or filter element. These channels are limited by the filter material with higher material density. In particular, the channel structure is maintained in that a planar structure is used in accordance with the invention as filter material.
- filter tow is drawn off the bale, prepared pneumatically and drawn according to the method customary for spatial filters.
- a non-woven nonwoven fabric with as high a strength as possible is produced in the direction of both surface axes as an intermediate, which can be wound onto spools and charged with additives.
- any suitable method for producing the tobacco smoke filter can be used.
- the apparatuses are particularly suitable a) for applying the additive from a slurry in an aqueous liquid or a volatile organic carrier or a plasticizing liquid for the threads, to each of which a binder may have been added, and b) for blowing of the small particle additive on the filaments, which may have previously been wetted with an adhesive or plasticizer.
- the adhesion of the particulate additives can be ensured by a hot melt adhesive, which is either applied together with the particulate additives or applied separately or activated by brief heating.
- the tobacco smoke filters according to the invention can be produced continuously from filter rods and cut to a limited length.
- Each individual element of such limited length could by itself serve as a tobacco smoke filter for a cigarette However, it is preferably used in a longitudinally aligned arrangement with at least one further filter element as part of a composite (eg double or triple) cigarette filter.
- a single filter element according to the present invention is used in conjunction with a longitudinally camming mouthpiece element of conventional appearance, for example, a unitary rod of cellulose acetate fiber tow.
- the integrally constructed tobacco smoke filter according to the invention is ver ⁇ relatively easy to manufacture in comparison to the corresponding comparative products of the prior art. This eliminates the costly production of said chamber filter of several filter elements. Another advantage is that, especially when the filter material is made of cellulose acetate, the smoky taste is judged to be particularly positive. " Also, the selective retention effect on phenols is observed.
- a filter tow of specification 2.1Y48 (filament denier 2.33 dtex, total 53 333 dtex) is prepared on a conventional two-stage drafting system KDF 2 from Hauni, Hamburg, and sprayed with 8% triacetin.
- the filter tow web with a minimum width of 250 mm is introduced into a pair of heated calender rolls and catalyzed with an effective line pressure of 40 kg / cm.
- the profiled calender rolls have a diameter of 230 cm and a grooved width of 350 mm and have 10 tread grooves per cm, while the other is unprofiled. They are heated with a silicone oil to 150 0 C.
- the groove profile is trapezoidal with an upper width of 0.4 mm and a depth of 0.5 miTL
- the nonwoven thus produced is wound up on a spool.
- a nonwoven spool is unwound continuously on a conventional padder and passed through a liquor which is filled with an aqueous activated carbon suspension.
- excess suspension is squeezed off on a pair of squeeze rolls.
- the squeegee rollers are driven at 10 m / min and thus ensure a uniform movement of the web through the suspension.
- the nonwoven is passed through a circulating air dryer at 150 0 C.
- the dryer has a drying distance of 4 m and thus ensures the drying of the suspension and the fixation of the activated carbon on the nonwoven.
- the nonwoven material doped with activated charcoal is folded strand-like on a commercially available KDF 2 from Körber, Hamburg, by insertion into an inlet nozzle, wrapped in paper and cut to a filter rod length of 126 mm.
- the diameter of the filter rods was set to 7.8 mm.
- a filter tow of specification 2.1Y48 (filament denier 2.33 dtex, total 53 333 dtex) is prepared on a conventional drawing system KDF 2 from Hauni, Hamburg, and sprayed with triacetin.
- the filter tow web is passed through a spreader nozzle with a minimum width of 200 mm and pneumatically mixed with activated carbon particles of about 250 ⁇ m particle size.
- the activated carbon powder is metered onto a suction nozzle continuously with a metering balance and blown by means of compressed air through a pipeline to the spreader nozzle.
- the spreader nozzle is preferably encapsulated with a box provided with a suction, which only has openings for the supply and removal of the filter tow web, in order to prevent the escape of coal dust into the environment.
