Definitions
- the present invention relates to a formulation for use as a lubricant in the manufacture of filaments.
- the threads are first prepared by a spinning process, which is preferably the solvent spinning process, and then further processed by applying the formulation of the invention on the surface of the threads as a lubricant.
- the threads produced are preferably cellulose acetate threads and these threads are used to make filters for tobacco products, especially cigarette filters.
- the patent GB 896,599 describes tobacco filters that can be used in cigarettes, pipes, cigarette holders or cigar tips.
- the filter elements described consist of bundles of continuous synthetic filaments, wherein water-insoluble calcium or magnesium salts are finely distributed on the surface of the filaments. These finely divided particles are fixed by oils on the fibers. In addition to mineral oils, these oils may also be high-boiling liquid esters of natural origin, liquid esters of natural fats or liquid high molecular weight fatty alcohols.
- the patent GB 765,962 describes a tobacco filter element consisting of cellulose acetate fibers.
- the cellulose acetate filter material is subjected to various processing steps, such as stretching and crimping of the fibers.
- electrostatic charging of the fibers must be prevented, and on the other hand, the surface of the fiber must be provided with a lubricant so that the fiber can be subjected to these processing steps.
- This lubricant contains a mineral oil with a purity that would make it suitable for the manufacture of pharmaceutical products.
- a rigid tobacco smoke filter consisting of a bundle of optionally crimped continuous filaments and a paper wrapper is described.
- the filaments consist of a mixture of a polyalphaolefin and a plasticizer-soluble polymer of an organic plasticizer.
- Liquid organic plasticizers which can be used in addition to light, medium and heavy mineral oils, liquid high-boiling organic esters or water-insoluble propylene glycols or polybutylene glycols.
- a cleaning composition containing white mineral oil is described.
- the emulsion is used for the treatment and cleaning of metal surfaces.
- the emulsion of the invention contains 20-50 wt.% Of a mineral oil having a viscosity of 50-380 Saybolt seconds, measured at 100 ° F and 0.5 to 10 wt.% Of an emulsifier.
- nonionic emulsifiers has been found to be advantageous.
- sorbitan esters and polyglycerides of fatty acids are also mentioned.
- emulsifier should be present in the emulsion as is just necessary to form a stable emulsion. In this case, 0.5 to 10% by weight of the emulsifier are present in the emulsion, with 1 to 5% by weight of emulsifier being preferred. If more emulsifier is present in the emulsion, milky stains or streaks may remain on the cleaned surface after cleaning.
- a thread which normally contains cellulose acetate
- a spinning process which is preferably the solvent spinning process.
- an acetone solution of cellulose acetate and matting agent TiO 2 is pressed through shower-like nozzles (spinnerets).
- the holes usually have cross sections in the form of an equilateral triangle.
- a heated spin shaft Below the spinnerets is a heated spin shaft. The air sucked through the spinning shaft heats up and absorbs the solvent which diffuses out of the formed filament, acetone, which almost is completely recovered.
- the solution solidifies under considerable volume shrinkage to a filament.
- the filaments When using triangular holes, the filaments have a Y-section.

Die Herstellung von Filtern für Tabakwaren findet in der Regel nach einem Prozess statt, bei dem zunächst ein Faden, der normalerweise Celluloseacetat enthält, mit Hilfe eines Spinnverfahrens, das bevorzugt das Lösungsmittelspinnverfahren ist, hergestellt wird.
Beim acetonischen Verfahren wird eine acetonische Lösung von Celluloseacetat und Mattierungsmittel TiO2 durch brauseähnliche Düsen (Spinndüsen) gepresst. Die Bohrungen haben üblicherweise Querschnitte in Form eines gleichseitigen Dreieckes. Unterhalb der Spinndüsen befindet sich ein beheizter Spinnschacht. Die durch den Spinnschacht gesaugte Luft erwärmt sich und nimmt das aus dem gebildeten Filament ausdiffundierende Lösungsmittel Aceton auf, welches fast vollständig zurückgewonnen wird. Hierbei verfestigt sich die Lösung unter erheblichem Volumenschwund zu einem Filament. Bei der Verwendung von dreieckigen Bohrungen haben die Filamente einen Y-Querschnitt. Wenn ein Faden, der aus mehreren Filamenten zusammengesetzt wird den Spinnschacht verlässt, so sind die Filamente im Faden dicht gepackt, ohne jedoch aneinander zu kleben.
Am Ausgang des Spinnschachts enthält der Faden typischerweise einen Restanteil von ca. 1 bis 6 Gew-% Aceton. Hier wird der Faden mit einer Präparation (Avivage), die hauptsächlich als Schmiermittel für die nachfolgenden Verarbeitungsschritte dient, versehen. Diese Präparation erfolgt durch einen Öler oder mit Hilfe einer Auftragswalze. In den nachfolgen Schritten wird zunächst der Gehalt an Aceton in den Fäden weiter reduziert, mehrere Fäden zu dem sogenannten Tau zusammengeführt und das Tau einem Kräuselungsprozess mittels einer Kräuselmaschine, die vorzugsweise nach dem Stauchkammerprinzip arbeitet, unterworfen. Zur Herstellung von Filtern für Tabakwaren wird dieses Tau durch ein konisches Maschinenteil geführt und so auf seine endgültige Dicke, also der Dicke des herzustellenden Filters komprimiert. Vor Einlauf in dieses konische Maschinenteil wird eine Glycerintriacetat enthaltende Zusammensetzung auf das Filtertau aufgebracht. Diese weitere Präparierung sorgt nach dem Verlassen des Komprimierteils durch Aushärten zu einer Fixierung des Filters in der gewünschten Form und Dicke.The manufacture of filters for tobacco products usually takes place after a process in which first a thread, which normally contains cellulose acetate, is produced by means of a spinning process, which is preferably the solvent spinning process.
In the acetone process, an acetone solution of cellulose acetate and matting agent TiO 2 is pressed through shower-like nozzles (spinnerets). The holes usually have cross sections in the form of an equilateral triangle. Below the spinnerets is a heated spin shaft. The air sucked through the spinning shaft heats up and absorbs the solvent which diffuses out of the formed filament, acetone, which almost is completely recovered. Here, the solution solidifies under considerable volume shrinkage to a filament. When using triangular holes, the filaments have a Y-section. When a thread composed of several filaments leaves the spinning shaft, the filaments in the thread are densely packed without, however, sticking to each other.
At the exit of the spinning shaft, the thread typically contains a residual fraction of about 1 to 6% by weight of acetone. Here, the thread is provided with a preparation (avivage), which serves mainly as a lubricant for the subsequent processing steps. This preparation is carried out by an oiler or by means of an applicator roll. In the subsequent steps, the content of acetone in the threads is first further reduced, a plurality of threads are combined to form the so-called rope and the rope is subjected to a crimping process by means of a crimping machine, which preferably works according to the stuffer box principle. To produce filters for tobacco products, this rope is passed through a conical machine part and thus compressed to its final thickness, ie the thickness of the filter to be produced. Before entering this conical machine part, a glycerol triacetate-containing composition is applied to the filter tow. This further preparation, after leaving the compression part by curing, fixes the filter in the desired shape and thickness.
Bei der Zusammenführung der Fäden zum Tau und der Komprimierung des Taus auf die endgültige Dicke dient die nach dem Trocknen der Fäden aufgebrachte Formulierung als Schmiermittel. Sie stellt u.a. sicher, dass die Reibung, die während der nachfolgenden Verarbeitungsschritte auftritt, einen Wert nicht überschreitet, der zum Abriß oder zu einer unerwünschten Erwärmung der Fäden bzw. des Taus führt. Beides würde unerwünschten Ausschuß bedingen. Zusätzlich werden durch das Schmiermittel höhere Maschinengeschwindigkeiten ermöglicht. Die Formulierung muss die bei diesem Prozess auftretenden hohen Scherkräfte ohne Wirkungsverlust überstehen.When merging the threads into the rope and compressing the rope to the final thickness, the formulation applied after the threads have dried acts as a lubricant. It ensures, inter alia, that the friction which occurs during the subsequent processing steps does not exceed a value which leads to the breakage or undesired heating of the threads or the rope. Both would cause unwanted rejects. In addition, the lubricant enables higher machine speeds. The formulation must withstand the high shear forces associated with this process without loss of effect.
Dieses Schmiermittel besteht üblicherweise aus einer Emulsion, die aus einer Mischung aus niedrigviskosem Mineralöl und Emulgator hergestellt wird. Weitere Komponenten können in der Emulsion enthalten sein.This lubricant usually consists of an emulsion which is prepared from a mixture of low-viscosity mineral oil and emulsifier. Other components may be included in the emulsion.
Die Mineralöle verbleiben nach der Herstellung der Filter und der entsprechenden Tabakwaren, die diese Filter enthalten, auf den Fäden.
Beim Rauchen z.B. einer Zigarette, die ein solches Filter enthält, kann ein Teil des Mineralöls, das sich auf dem Filter befindet, vom Raucher aufgenommen werden. Mitte der 90'er Jahre haben Baldwin et al. (
For example, when smoking a cigarette containing such a filter, some of the mineral oil that is on the filter may be absorbed by the smoker. In the mid 90's Baldwin et al. (
Die Aufgabe der vorliegenden Erfindung ist es, eine stabile und lagerfähige Emulsion bereit zu stellen, die hochviskose Mineralöle mit einer Viskosität von mindestens 8,5 mm2/s bei 100°C enthält. Hierzu ist es notwendig, Emulgatoren zur Herstellung einer verarbeitbaren Formulierung zu finden. Die Formulierung wird dann im Austausch gegen die verwendeten Formulierungen, die niedrigviskose Mineralöle enthalten, eingesetzt.The object of the present invention is to provide a stable and storable emulsion containing high viscosity mineral oils having a viscosity of at least 8.5 mm 2 / s at 100 ° C. For this it is necessary to find emulsifiers for the preparation of a processible formulation. The formulation is then used in exchange for the formulations containing low viscosity mineral oils.
Die Aufgabe der vorliegenden Erfindung wird durch eine Formulierung zur Verwendung als Präparation bei der Herstellung von Fäden enthaltend a) 30-80 Gew.-% eines Mineralöls mit einer Viskosität von mindestens 8,5 mm2/s bei 100°C und b) 11-60 Gew.-% eines Emulgators ausgewählt aus Sorbitanmonoester, Derivate von Sorbitanmonoestern, Sorbitandiestern, Derivate von Sorbitandiestern, Sorbitantriestern, Derivate von Sorbitantriestern, Polyglycerinestern, Derivate von Polyglycerinestern, Polyricinoleat, Derivate von Polyricinoleat und Mischungen derselben erreicht, wobei die Formulierung eine Wasser-in-Öl oder eine Öl-in-Wasser Emulsion ist.The object of the present invention is achieved by a formulation for use as a preparation in the production of threads containing a) 30-80 wt .-% of a mineral oil having a viscosity of at least 8.5 mm 2 / s at 100 ° C and b) 11 60% by weight of an emulsifier selected from sorbitan monoesters, derivatives of sorbitan monoesters, sorbitan diesters, derivatives of sorbitan diesters, sorbitan triesters, derivatives of sorbitan triesters, polyglycerol esters, derivatives of polyglycerol esters, polyricinoleate, derivatives of polyricinoleate and mixtures thereof, the formulation comprising a water in oil or an oil-in-water emulsion.
Unerwarteterweise zeigte sich, dass solche Formulierungen eine vergleichbare und teilweise sogar bessere Lager- und Verarbeitungsstabilität haben. Die Stabilität einer Formulierung, die als Emulsion vorliegen kann, lässt sich durch die Trübung der Formulierung bestimmen. Dabei gilt grundsätzlich, dass eine höhere Trübung eine geringere Stabilität anzeigt. Die Verarbeitungsstabilität der Formulierung lässt sich dadurch prüfen, indem die Trübung der Formulierung während der Verarbeitung überprüft wird. Dabei ist keine oder eine geringe Zunahme der Trübung besonders vorteilhaft, während eine stärkere Zunahme der Trübung auf eine nicht ausreichende Formulierungssstabilität schließen lässt. Die Lagerstabilität einer Formulierung lässt sich durch Überprüfung der Trübung nach z.B. fünf Tagen Lagerung bei 23°C überprüfen. Ist eine Zunahme der Trübung nach einer solchen Lagerzeit nicht feststellbar oder sehr gering, so ist die Lagerstabilität der Formulierung als sehr gut zu beurteilen, während eine Zunahme der Trübung bzw. ein eventuelles Entmischen der Phasen als schlechte Lagerstabilität zu charakterisieren ist.Unexpectedly, it has been found that such formulations have comparable and sometimes even better storage and processing stability. The stability of a formulation which may be in the form of an emulsion can be determined by the turbidity of the formulation. It basically applies that a higher turbidity indicates a lower stability. The processing stability of the formulation can be checked by checking the turbidity of the formulation during processing. No or little increase in turbidity is particularly advantageous, while a greater increase in turbidity indicates inadequate formulation stability. The storage stability of a formulation can be checked by checking the turbidity after, for example, five days storage at 23 ° C. If an increase in turbidity after such a storage time is not detectable or very low, then the storage stability of the formulation is to be assessed as very good, while an increase in turbidity or a possible segregation of the phases is to be characterized as poor storage stability.
Bei dem erfindungsgemäßen hochviskosen Mineralöl ist die Viskosität bei 100°C gemessen nach ASTM D 445 mindestens 8,5 mm2/s. Das eingesetzte Mineralöl hat bevorzugt eine Viskosität von 8,5 bis 1000, besonders bevorzugt von 8,5 bis 20 und ganz besonders bevorzugt von 8,5 bis 11 mm2/s.In the case of the high-viscosity mineral oil according to the invention, the viscosity at 100 ° C., measured according to ASTM D 445, is at least 8.5 mm 2 / s.

Aus diesen Fäden lassen sich Filter für Tabakwaren herstellen. Hierbei ist es bevorzugt, dass die Filter Zigarettenfilter sind. Bei allen Arbeitsschritten verbleibt die aufgebrachte Emulsion auf den Fäden und somit auf dem Tau. Somit ist die Emulsion zu einem gewissen Anteil auch noch in den Filtern für Tabakwaren und den Tabakwaren selbst vorhanden.From these threads can be produced filters for tobacco products. It is preferred that the filters are cigarette filters. In all operations, the applied emulsion remains on the threads and thus on the rope. Thus, to a certain extent, the emulsion is still present in the filters for tobacco products and the tobacco itself.
Die erfindungsgemäße Emulsion wird an folgenden Beispielen erläutert, ohne jedoch auf diese Beispiele beschränkt zu sein.The emulsion according to the invention is illustrated by the following examples, but without being limited to these examples.
2 + 20 EO bedeutet 20 mol Ethylenoxideinheiten pro mol Ester 1 Primol ® 352 is a high viscosity mineral oil of ESSO AG viscosity according to ASTM D 445: 71 mm 2 / s at 40 ° C, 9.0 mm 2 / s at 100 ° C
2 + 20 EO means 20 moles of ethylene oxide units per mole of ester
Die Formulierungen 1 und 2 aus Tabelle 1 enthalten beide die erfindungsgemäße Kombination aus einem Mineralöl mit einer Viskosität von wenigstens 8,5 mm2/s bei 100°C und dem erfindungsgemäßen Emulgator. Die Emulsionen lassen sich nach Standardmethoden herstellen.
Zur Herstellung der Formulierung 1 wird Primol 352 bei Raumtemperatur vorgelegt und unter ständigem Rühren werden die Rohstoffe in der Reihenfolge Sorbitanmonolaurat, Sorbitanmonolaurat + 20 EO, Sorbitanmonooleat, Polyglyzerin-Polyricinoleat und Wasser zugegeben. Formulierung 1 wird für weitere 30 Minuten gerührt.
Zur Herstellung der Formulierung 2 wird auf 50°C erwärmtes Primol 352 in einem Rührer vorgelegt. Unter ständigem Rühren und bei 50°C werden die weiteren Rohstoffe in der Reihenfolge Sorbitanmonolaurat, Sorbitanmonolaurat + 20 EO, Sorbitantristearat + 20 EO, Polyglycerin-Polyrizinoleat und Wasser zugegeben. Nach 30 Minuten rühren bei 50 °C lässt man die Formulierung auf Raumtemperatur abkühlen und rührt sie bei dieser Temperatur für weitere 30 Minuten.Formulations 1 and 2 from Table 1 both contain the combination according to the invention of a mineral oil having a viscosity of at least 8.5 mm 2 / s at 100 ° C. and the emulsifier according to the invention. The emulsions can be prepared by standard methods.
To prepare Formulation 1, Primol 352 is initially charged at room temperature and, while stirring continuously, the raw materials are added in the order of sorbitan monolaurate, sorbitan monolaurate + 20 EO, sorbitan monooleate, polyglycerol polyricinoleate and water. Formulation 1 is stirred for a further 30 minutes.
To prepare formulation 2, primer 352 heated to 50 ° C. is initially charged in a stirrer. With continuous stirring and at 50 ° C, the further raw materials are added in the order of sorbitan monolaurate, sorbitan monolaurate + 20 EO, sorbitan tristearate + 20 EO, polyglycerol polyricinoleate and water. After stirring for 30 minutes at 50 ° C, the formulation is allowed to cool to room temperature and stirred at this temperature for a further 30 minutes.
Beide Formulierungen werden zur Herstellung von Celluloseacetatfäden nach dem Lösungsmittelspinnverfahren eingesetzt. Hierbei zeigte sich bei der Herstellung der Fäden kein negativer Einfluss der erfindungsgemäß eingesetzten Formulierungen. Formulierung 1 und Formulierung 2 zeigen eine Lagerstabilität bei 23°C und fünf Tagen, die mit den üblicherweise eingesetzten Formulierungen vergleichbar ist und während der Verarbeitung der Fäden zu Filtern trat keine Zunahme der Trübung der Emulsion bedingt durch auftretende Scherkräfte ein. Beide Formulierungen verhielten sich vergleichbar mit den üblicherweise eingesetzten Formulierungen. Both formulations are used to produce cellulose acetate filaments by the solvent spinning method. In this case, no negative influence of the formulations according to the invention was shown in the production of the threads. Formulation 1 and Formulation 2 show storage stability at 23 ° C and five days, comparable to the formulations commonly used, and no increase in clouding of the emulsion due to shear forces occurred during processing of the filaments into filters. Both formulations behaved similarly to the commonly used formulations.
