Description

Die vorliegende Erfindung betrifft einmal ein Verfahren zur Herstellung eines sauer gestellten Filters für Tabakprodukte durch Imprägnieren eines faserigen oder flächigen Filtermaterials gemäß Oberbegriff Hauptanspruch sowie ferner die Verwendung derartiger Filter für Cigarettenhülsen, Cigaretten, Cigarren bzw. Cigarillos und für Rauchgeräte.The present invention relates to a method for producing an acid provided filters for tobacco products by impregnating a fibrous or flat Filter material according to the preamble main claim and also the use of such Filters for cigarette tubes, cigarettes, cigars or cigarillos and for Smoking Devices.

Es ist aus der DE 16 92 895 A1 bekannt, Filtermaterial für Tabakprodukte zur besseren Absorption von basischen Anteilen des Tabakrauchs und zur Absorption von Nikotin mit sauren Komponenten auszurüsten, wobei diese zusammen mit dem zur Filterverfestigung dienenden Glycerintriacetat (Triacetin) auf das Celluloseacetat-Tau gegeben werden. Die hier erwähnten und zur Herstellung von sauer gestellten Filtern verwendeten physiologisch und sensorisch unbedenklichen Genußsäuren lösen sich jedoch nur in geringer Menge bzw. auch nur bei höheren Temperaturen von 100 bis 130° C in dem als Carbonsäureester-Härter verwendeten Triacetin. Dieses hat den Nachteil, dass eine gleichmäßige und auch gleichzeitige Imprägnierung der Filter mit der sauren Komponente und der Härterkomponente auf erhebliche Schwierigkeiten stößt.It is known from DE 16 92 895 A1, filter material for tobacco products for better Absorption of basic parts of tobacco smoke and absorption of nicotine equip with acidic components, these together with that for filter solidification serving glycerol triacetate (triacetin) on the cellulose acetate dew are given. The filters mentioned here and for the production of acidified filters The physiologically and sensorially safe edible acids used dissolve however only in small quantities or only at higher temperatures from 100 to 130 ° C in the triacetin used as the carboxylic acid ester hardener. This has that Disadvantage that the filter is impregnated evenly and simultaneously the acidic component and the hardener component on considerable difficulties encounters.

Aus diesem Grunde hat man gemäß DE 13 00 854 C1 saure Ester organischer Genußsäuren wie Citronensäure, Weinsäure, Bernsteinsäure, Äpfelsäure und Zuckersäure verwendet, die in Glycerintriacetat gelöst auf den Fasern des Filtermaterials fein verteilt werden können. Nachteil dieses Verfahrens ist jedoch, dass die Ester der jeweiligen Polycarbonsäuren eine nur sehr schwache Retention gegenüber basischen Rauchinhaltsstoffen aufweisen, da die reaktiven Säuregruppen in diesem Falle verestert sind und damit nicht mehr für die selektive Retention von basischen Rauchkomponenten zur Verfügung stehen.For this reason, according to DE 13 00 854 C1, there are acidic esters of organic edible acids such as citric acid, tartaric acid, succinic acid, malic acid and sugar acid used, which dissolved in glycerol triacetate finely distributed on the fibers of the filter material can be. The disadvantage of this method, however, is that the esters of the particular Polycarboxylic acids have only a very weak retention compared to basic smoke ingredients have, since the reactive acid groups are esterified in this case and therefore no longer for the selective retention of basic smoke components be available.

Bei einem anderen Verfahren gemäß DE 38 20 089 C2 werden die Säureanhydride der entsprechenden Di- oder Polycarbonsäuren in den als Filterhärter eingesetzten Carbonsäureestern gelöst und nach dem Aufsprühen auf die Filterfasern hydrolysiert. Nachteil dieses Verfahrens ist zum einen die sehr aufwendige und damit teure Herstellung der Säureanhydride und zum anderen die Instabilität der gelösten Anhydride, die bereits durch Spuren von Wasser im verwendeten Lösungsmittel oder durch Luftfeuchtigkeit zu den entsprechenden Säuren hydrolysiert werden und als Säuren aus dem Lösungsmittel auskristallisieren.In another process according to DE 38 20 089 C2, the acid anhydrides are the corresponding di- or polycarboxylic acids in the carboxylic acid esters used as filter hardeners dissolved and hydrolyzed after spraying on the filter fibers. disadvantage on the one hand, this method is the very complex and therefore expensive production of the Acid anhydrides and secondly the instability of the dissolved anhydrides, which already by traces of water in the solvent used or by air humidity to be hydrolyzed to the corresponding acids and as acids from the solvent crystallize.

Bei anderen bekannten Verfahren werden die Di- oder Polycarbonsäuren in Form sehr feiner Teilchen entweder gemäß EP 09 13 100 A2 über eine Dosiereinrichtung direkt auf den Strang aus Filtermaterial bei der Filterherstellung aufgebracht oder diese sehr feinen Teilchen werden gemäß DE 39 04 239 C1 in einem organischen, flüssigen Medium suspendiert und die erhaltene Suspension auf das Filtermaterial aufgebracht. Hierbei ist die Herstellung der kleinen Teilchen durch Mikronisieren überaus kostspielig; zum anderen benötigt man entweder zusätzliche Dosiereinrichtungen an der Filterherstellungsmaschine oder die eingesetzten Suspensionen zeigen eine Instabilität, wodurch sich die feinen Teilchen mit der Zeit auf dem Boden absetzen. In other known processes, the di- or polycarboxylic acids are very in the form fine particles either according to EP 09 13 100 A2 directly via a metering device applied to the strand of filter material during filter production or this very According to DE 39 04 239 C1, fine particles are in an organic, liquid medium suspended and the suspension obtained applied to the filter material. Here, the production of the small particles by micronization is extremely expensive; on the other hand, either additional metering devices are required the filter manufacturing machine or the suspensions used show instability, whereby the fine particles settle on the floor over time.

Bislang ist kein Verfahren bekannt, bei dem auf wirtschaftliche Weise in einem Standardverfahren zur Filterherstellung feste organische Säuren oder deren saure Salze in den üblicherweise eingesetzten Filterhärtern gelöst auf das Filtermaterial aufgebracht werden können.So far, no method is known in which in an economical manner in a standard procedure for filter manufacture solid organic acids or their acid salts in the filter hardener usually used applied to the filter material can be.

Die Erfindung hat sich die Aufgabe gestellt, ein Verfahren zur Herstellung eines sauer gestellten Filters für Tabakprodukte vorzuschlagen, bei dem die bei Umgebungs- und Verarbeitungstemperaturen kristallinen Genußsäuren beziehungsweise deren saure Salze zusammen mit einem als Filterhärter eingesetzten organischen Lösungsmittel wie einem Carbonsäureester-Härter gelöst werden können, damit die erhaltene klare Lösung in üblicher Weise auf das Filtermaterial aufgebracht werden kann.The invention has for its object a method for producing an acid proposed filters for tobacco products, in which the environmental and Processing temperatures of crystalline edible acids or their acidic ones Salts together with an organic solvent used as a filter hardener as a carboxylic acid ester hardener can be solved so that the result is clear Solution can be applied to the filter material in the usual way.

  • a) physiologisch und sensorisch unbedenklichen und als Genußsäuren bezeichneten Mono-, Di- oder Polycarbonsäuren oder Hydroxysäuren mit bis zu 8 Kohlenstoffatomen und 2 bis 3 Carboxylgruppen bzw. mit deren sauren Salzen und
  • b) einer Carbonsäureester-Härterkomponente vorgeschlagen,
    • welches dadurch gekennzeichnet ist, dass man diese Genußsäuren bzw. deren saure Salze und die Carbonsäureester-Härterkomponente durch Zusatz eines alkoholischen Lösungsvermittlers aus der Gruppe von Methyl-, Ethyl-, Propyl-, iso-Propyl-, Butyl- und iso-Butylalkohol oder deren Mischungen in Lösung bringt und die derart erhaltene Lösung auf das Filtermaterial aufbringt.To solve this problem, starting from the known method according to DE 39 04 239 C1, a method for producing an acidified filter for tobacco products by impregnating a fibrous or flat filter material with
  • a) physiologically and sensorially harmless and referred to as edible acids mono-, di- or polycarboxylic acids or hydroxy acids with up to 8 carbon atoms and 2 to 3 carboxyl groups or with their acidic salts and

    • which is characterized in that these edible acids or their acid salts and the carboxylic acid ester hardener component by adding an alcoholic solubilizer from the group of methyl, ethyl, propyl, iso-propyl, butyl and iso-butyl alcohol or their Bring mixtures in solution and apply the solution thus obtained to the filter material.

    Das erfindungsgemäße Verfahren hat die folgenden überraschenden Vorteile gegenüber den bekannten Verfahren:

    • Die Verteilung der Genußsäuren oder deren sauren Salze auf den Filterfasern ist sehr fein und homogen, so dass eine äußerst hohe Wirksamkeit erzielt werden kann.
    • Die Aufbringung der Genußsäuren oder deren sauren Salze erfordert keinerlei besondere Maßnahmen bei der Herstellung der Filter. Es sind weder Maschinenmodifikationen notwendig noch schränkt die kritische Stabilität und Homogenität der eingesetzten Lösung die Verarbeitbarkeit in irgendeiner Art und Weise ein.
    • Das Verfahren gestattet den Einsatz preiswerter Rohstoffe, da für die Herstellung der benötigten Lösung Standardprodukte ohne besondere aufwendige Vorbehandlung wie Mikronisieren oder Lösen bei Temperaturen über 100° C eingesetzt werden können.
    The process according to the invention has the following surprising advantages over the known processes:
    • The distribution of the edible acids or their acidic salts on the filter fibers is very fine and homogeneous, so that extremely high effectiveness can be achieved.
    • The application of the edible acids or their acid salts does not require any special measures in the manufacture of the filters. No machine modifications are necessary, and the critical stability and homogeneity of the solution used does not limit the processability in any way.
    • The process allows the use of inexpensive raw materials, since standard products can be used for the production of the required solution without special, expensive pretreatment such as micronizing or dissolving at temperatures above 100 ° C.

    Als Filterverfestigungsmittel können allgemein alle üblichen und hier als Carbonsäureester-Härter bezeichneten Ester verwendet werden, wie sie in der DE 39 04 239 C1 beschrieben sind, wobei insbesondere Glycerintriacetat (Triacetin) Polyethylenglykolacetate bzw. -propionate und insbesondere Triethylenglykoldiacetat (TEGDA) geeignet sind.All conventional and here as carboxylic ester hardeners can be used as filter hardening agents designated esters are used, as in DE 39 04 239 C1 are described, in particular glycerol triacetate (triacetin) polyethylene glycol acetates or -propionate and especially triethylene glycol diacetate (TEGDA) are.

    Vorzugsweise wird die Lösung aus Genußsäuren bzw. aus deren sauren Salzen, der Carbonsäureester-Härterkomponente und dem alkoholischen Lösungsvermittler für ein Filtermaterial verwendet, das aus Fasern oder Vliesen aus Celluloseacetat, Cellulose, Polyethylen oder Polypropylen besteht.The solution is preferably made from edible acids or from their acid salts, the Carboxylic ester hardener component and the alcoholic solubilizer for one Filter material used, which consists of fibers or nonwovens made of cellulose acetate, cellulose, There is polyethylene or polypropylene.

    Als Genußsäuren werden bevorzugt Maleinsäure, Bernsteinsäure, Glutarsäure, Weinsäure, Äpfelsäure, Citronensäure und/oder Acetylcitronensäure bzw. deren saure Salze verwendet, wobei man insbesondere als saure Salze die sauren Alkali- und insbesondere Kalium salze oder Ammoniumsalze verwendet.Maleic acid, succinic acid, glutaric acid, tartaric acid are preferred as edible acids.

    Die erfindungsgemäß als Lösungsvermittler eingesetzten Alkohole haben ein gutes Lösungsvermögen für die Polycarbonsäuren bzw. für deren Salze. Besonders bevorzugt ist Ethanol, da dieser besonders gut als Lösungsvermittler geeignet ist und schon geringe Mengen ausreichen, um die Genußsäuren z.B. in Glycerintriacetat (Triacetin) zu lösen und letztlich weil Ethanol auch ein ansonsten in der Tabakindustrie übliches Lösungsmittel ist. Hinzu kommt eine verbesserte Löslichkeit für Celluloseacetat-Fasern, d.h. die entsprechenden Celluloseacetat-Filter härten schneller aus.The alcohols used according to the invention as solubilizers have a good one Solubility for the polycarboxylic acids or for their salts.
