Verwendung von Aminoxiden bei der Zellstoff- und Papier-Use of amine oxides in pulp and paper
herstellung Die Erfindung betrifft die Verwendung von oberflächenaktiven Aminoxiden bei der Herstellung von Zellulose oder Papier mit geringer mechanischer Festigkeit, hoher Saugfähigkeit und Weichheit.manufacture The invention relates to the use of surface-active substances Amine oxides in the production of cellulose or paper with low mechanical Strength, high absorbency and softness.
Es ist bereits bekannt, daß durch Zugabe von oberflächenaktiven Substanzen zu einer wäßrigen Zellulosepulpe die Bindung zwischen den Fasern der Zellulose vermindert wird. Man erhält auf diese Weise Zellstoff bzw. Papier mit größerer Weichheit und verminderter mechanischer Festigkeit. Diese Eigenschaften sind erwünscht, wenn die Zellulosebahn zu "fluff", einer flockigen Schicht terfasert werden soll Derartige Arbeitsweisen und die hierbei verwendeten oberflächenaktiven Hilfsmittel sind beispielsweise beschrieben in DE-B 22 56 239 und DE-B 25 02 357. Bei diesen oberflächenaktiven Hilfsmitteln handelt es sich um quartäre Ammoniumverbindungen, die sich von Fettalkoholen, oxethylierten Fettalkoholen oder oxalkylierten Alkylphenolen ableiten. Diese Substanzen ziehen aufgrund ihrer substantiven Eigenschaften auf die Faseroberfläche auf und vermindern dadurch den Energiebedarf: bei der Trockenzerfaserung.It is already known that by adding surface-active substances to an aqueous cellulose pulp, the bond between the fibers of the cellulose is reduced will. This gives pulp or paper with greater softness and reduced mechanical strength. These properties are desirable when the Cellulose web to be "fluff", a fluffy layer that is intended to be fiberized Working methods and the surface-active auxiliaries used here are for example described in DE-B 22 56 239 and DE-B 25 02 357. Surface-active in these Aids are quaternary ammonium compounds, which differ from fatty alcohols, Derive oxyethylated fatty alcohols or oxyalkylated alkylphenols. These substances attract due to their substantive properties on the fiber surface and thereby reduce the energy requirement: during dry fiberization.
Es wurde nun gefunden, daß Dian Zellulose oder Papier mit besonders vorteilhaften Eigenschaften hinsichtlich der Verwendung in Hygiene-Produkten erhält, wenn man der Zellstoffsuspension oder dem daraus geformten Papier Aminoxide der allgemeinen Forrael I in der R1 geradkettige oder verzweigte Alkylreste mit 8 bis 22 C-Atomen, R2 Wasserstoff und/oder C1 -C2-Alkyl, R3 und R4 unabhängig voneinander C1-C3-Alkyl oder (CH2 CH2O)m-H mit m = 1 - 5 und n Werte von 0 - 15 bedeuten, zusetzt.It has now been found that Dian cellulose or paper with particularly advantageous properties with regard to use in hygiene products is obtained if amine oxides of the general formula I are added to the cellulose suspension or the paper formed therefrom in which R1 straight-chain or branched alkyl radicals with 8 to 22 carbon atoms, R2 hydrogen and / or C1 -C2 -alkyl, R3 and R4 independently of one another C1-C3-alkyl or (CH2 CH2O) mH with m = 1-5 and n Values from 0 - 15 mean adding.
Durch die Verwendung der Aminoxide der Formel I gemäß der Erfindung wird die mechanische Festigkeit der Zelluloseprodukte weiter herabgesetzt, e'ine gute Benetzbarkeit und darüber hinaus eine vorteilhafte hohe Saugkapazität der daraus hergestellten Hygiene-Produkte erreicht.By using the amine oxides of the formula I according to the invention the mechanical strength of the cellulose products is further reduced, e'ine good wettability and, moreover, an advantageous high suction capacity of the resulting manufactured hygiene products.
Die vorteilhaften Wirkungen der Aminoxide der Formel I bei der Zellstoff- und Papierherstellung sind umso erstaunlicher, als die kninoxide aufgrund ihres strukturellen Aufbaus verglichen mit quaternären Ammoniumverbindungen nur äußerst geringe substantive Eigenschaften besitzen.The beneficial effects of the amine oxides of the formula I in pulp and papermaking are even more astonishing than the kninoxide because of their structural structure compared to quaternary ammonium compounds only extremely have low substantive properties.
Ihre bevorzugte Eignung bei der Verwendung gemäß der vorliegenden Erfindung dürfte unter anderem auf ihre gute antistatische Wirkung zurückzuführen sein.Your preferred suitability for use in accordance with the present Invention is believed to be due, among other things, to its good antistatic effect be.
Die Aminoxide der Formel I können nach bekannten Verfahren entsprechend dem allgemeinen Reaktionsschema X = Halogen oder -OSO 3Me, Me = Alkalimetall hergestellt werden.The amine oxides of the formula I can be prepared by known processes according to the general reaction scheme X = halogen or -OSO 3Me, Me = alkali metal.
Vorzugsweise kommen solche Aminoxide der Formel I zur Anwendung, bei denen R2 Wasserstoff und n 0 oder Werte von 1 bis 10 darstellen.Such amine oxides of the formula I are preferably used where R2 is hydrogen and n is 0 or values from 1 to 10.
Die Aminoxide der Formel I werden der Zellstoffsuspension, die für die erstellung von Hygiene-Zellstoff gedacht ist, in der Regel nach dem Bleichprozeß vor oder während der Verformung zu kontinuierlichen Bahnen auf einer Zellstoffentwässerungs- oder einer Papiermaschine zugesetzt. Die Aminoxide werden zweckmäßig als 1 bis 15 %ige wäßrige Lösung in solchen Mengen zugegeben, daß die Einsatzmenge 0,02 bis etwa 2 %, vorzugsweise 0,1 bis 1 %, bezogen auf das Trockengewicht der Zellulose beträgt.The amine oxides of the formula I are the pulp suspension, which for The creation of hygienic pulp is intended, as a rule, after the bleaching process before or during the deformation into continuous webs on a pulp dewatering or added to a paper machine. The amine oxides are conveniently classified as 1 to 15 % aqueous solution is added in such amounts that the amount used is 0.02 to about 2%, preferably 0.1 to 1%, based on the dry weight of the cellulose.
Die Zugabmenge hängt insbesondere von der gewünschten Wirkung an. Sie kann erforderlichenfalls die vorstehend angegebene obere Grenze auch noch überschreiten.The amount added depends in particular on the desired effect. If necessary, it can also exceed the upper limit specified above.
Die gemäß der Erfindung behandelte Zellulose oder das Papier können für die verschiedenen Hygiene-Produkte wie z.B. ToilStenpapier, Papierhandtücher und Textilersatzmaterialien und dergleichen verwendet werden.The cellulose treated according to the invention or the paper can for the various hygiene products such as toilet paper, paper towels and textile substitute materials and the like can be used.
Die Erfindung wird durch die folgenden Beispiele weiter erläutert Beispiele 1 bis 4 Einer 3 %igen Zellstoffsuspension, die für sanitäre Zwecke geeignet ist und die im Laboratoriumspulper 2 Minuten lang aufgeschlagen wurde, wurden Aminoxide der Formel 1 in 1 %iger Lösung zugesetzt. ,)ie so behandelten Zellstoff-Suspensionen wurden auf 2 % verdünnt; anschlie-Bend wurde in der Blattbildungssäule des "Rapid-Köthen-Blattbildner" jeweils ein Blatt mit einem Flächengewicht von 300 g/m2 gebildet. Die so hergestellten Prüfblätter wurden auf eie dampfbeheizten und filzbespannten Trocken zylinder getrocknet und 48 h lang bei 200C und 65 % relativer Luftfeuchte klimatisiert.The invention is further illustrated by the following examples Examples 1 to 4 A 3% pulp suspension suitable for sanitary purposes and which was whipped in the laboratory pulper for 2 minutes, became amine oxides the formula 1 added in 1% solution. ,) ie so treated Pulp suspensions were diluted to 2%; Subsequently, in the sheet formation column of the "Rapid-Köthen-Blattbildner" each formed a sheet with a basis weight of 300 g / m2. The so produced Test sheets were dried on a steam-heated and felt-covered drying cylinder and air-conditioned for 48 hours at 200C and 65% relative humidity.
Die so hergestellten Blätter wurden folgenden Prüfungen unterworfen: 1. Berstfestigkeit (kPa) nach DIN 53141, Teiles (7.77), ZMV/13/62 2. Saughöhe entsprechend ZMV/15/60, wobei die Methode dadurch abgewandelt wurde, daß die Zeit in Sekunden bestimmt wurde, die das Prüfmedium Wasser benötigt, um einen 15 mm breiten Streifen 4 cm hoch zu steigen 3.
