Verfahren zur Herstellung eines keimfähigen PapieresProcess for the production of a germinable paper
Die Erfindung betrifft ein Verfahren zur Herstellung eines keimfähigen Papieres nach dem Oberbegriff des Anspruchs 1 und ein keimfähiges Papier, das nach diesem Verfahren hergestellt wird.The invention relates to a method for producing a germinable paper according to the preamble of claim 1 and a germinable paper which is produced by this method.
Papier ist ein flächiger, im wesentlichen aus Fasern, vorwiegend pflanzlicher Herkunft, bestehender Werkstoff. Er wird durch Entwässerung einer Faserstoffaufschwemmung gebildet, wobei aus den entwässerten Fasern ein Faserfilz entsteht, der anschließend verdichtet und getrocknet wird.Paper is a flat material consisting essentially of fibers, predominantly of vegetable origin. It is formed by dewatering a pulp suspension, whereby the dewatered fibers form a fiber felt, which is then compressed and dried.
Zu dem Papierbrei können Papierhilfsmittel, wie Füllstoffe, Farbstoffe, Harz, Leim, Alaun, Flockungsmittel, Netzmittel, Konservierungsmittel, Schleimbekämpfungsmittel, Weichmacher u.s.w. in Abhängigkeit von der zu fertigenden Papierqualität zugegeben werden. Der Papierbrei wird gründlich durchmischt und auf eine 3%ige, wässrige Suspension eingestellt, die fallweise auch auf 0,2 bis 0,5 % verdünnt werden muß, um in einer Papiermaschine, wie z.B. einer Langsiebpapiermaschine oder einer Rundsiebpapiermaschine verarbeitet werden zu können.Paper auxiliaries such as fillers, dyes, resin, glue, alum, flocculants, wetting agents, preservatives, slime control agents, plasticizers, etc. can be added to the pulp. depending on the paper quality to be produced. The paper pulp is thoroughly mixed and adjusted to a 3% aqueous suspension, which in some cases also has to be diluted to 0.2 to 0.5% in order to be used in a paper machine, e.g. a Fourdrinier paper machine or a rotary screen paper machine.
Zur Herstellung von Gruß- oder Glückwunschkarten ist es beispielsweise aus der WO 94/16907 bekannt, den Faserbrei oder der bereits geformten Papierbahn keimfähige Pflanzensamen zuzuführen, um der Karte eine besondere Note, nämlich als dauerhaftes Geschenk, zu geben. Die bekannten Karten werden jedoch entweder im teuren Kaschierverfahren, d.h. die Samen werden zwischen zwei Lagen Papier eingebet- tet hergestellt oder mit der Hand gefertigt, wodurch jedoch die Oberfläche eine derartige Rauhigkeit aufweist, daß eine maschinelle Bedruckbarkeit (Offset, Buchdruck, Siebdruck etc.) nicht möglich ist. Auch sind bei einer Handfertigung hohe Produktionsmengen bei zu vertretenden Kosten nicht möglich.For the production of greeting or greeting cards, it is known, for example from WO 94/16907, to supply the fiber pulp or the already formed paper web with germinable plant seeds in order to give the card a special note, namely as a permanent gift. However, the known cards are either made using the expensive laminating process, ie the seeds are embedded between two layers of paper. tet manufactured or made by hand, however, the surface has such a roughness that a machine printability (offset, letterpress, screen printing, etc.) is not possible. In the case of manual production, too, high production quantities are not possible at cost.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung eines keimfähigen Papiers zu schaffen, mit dem das Papier unter Gewährleistung einer hohen Oberflächenqualität maschinell und kostengünstig herzustellen ist .The invention has for its object to provide a method for producing a germinable paper with which the paper can be produced mechanically and inexpensively while ensuring a high surface quality.
Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1.The features of claim 1 serve to achieve this object.
Die Erfindung sieht in vorteilhafter Weise vor, daß die Trockenvorrichtung auf eine durchschnittliche Temperatur von 75 °C bis 130 °C beheizt wird, und daß die Papierbahn mit einer Geschwindigkeit von ca. 2 bis 20 m/min, vorzugsweise ca. 3 m/min bis 8 m/min durch die Trockenvorrichtung geführt wird. Mit diesen Parametern wird ein Endtrockengehalt des Papiers gewährleistet, der nötig ist, um eine Papierqualität zu erreichen, die den Anforderungen an heutige Druckerzeugnisse, wie z.B. Grußkarten aller Art, Visitenkarten, Verpackungsmaterial etc. genügt. Gleichzeitig wird die Keimfähigkeit der Pflanzensamen in der Weise bewahrt, daß die Pflanzensamen nicht zu früh keimen oder gar abgetötet werden.The invention advantageously provides that the drying device is heated to an average temperature of 75 ° C to 130 ° C, and that the paper web at a speed of about 2 to 20 m / min, preferably about 3 m / min up to 8 m / min through the drying device. These parameters ensure a final dry content of the paper, which is necessary to achieve a paper quality that meets the requirements of today's printed products, such as Greeting cards of all kinds, business cards, packaging material etc. are sufficient. At the same time, the germination capacity of the plant seeds is preserved in such a way that the plant seeds do not germinate too early or are even killed.
Die Produktivität des Herstellungsprozesses Papiers liegt dabei im Bereich bis zu 100 kg/h und die Kosten belaufen sich auf ca. DM 8,-- bis 22, --/kg. Damit die Pflanzensamen in der Pressenvorrichtung nicht zerdrückt werden, wird die Papierbahn einer maximalen Anpreßkraft pro Bahnbreite von ca. 25 kp/cm ausgesetzt.The productivity of the paper manufacturing process is in the range up to 100 kg / h and the costs amount to approx. DM 8 to 22 / kg. So that the plant seeds are not crushed in the press device, the paper web is exposed to a maximum contact force per web width of approx. 25 kp / cm.
Dadurch, daß die Papierbahn in der Pressenvorrichtung zwischen Trockenfilzbahnen geführt wird, wird der Anpreßdruck verringert und eine schonende Trocknung gewährleistet. Um eine optimale Keimfähigkeit beizubehalten, sollte eine Eigentemperatur der Papierbahn von ca. 75 °C nicht überschritten werden.Because the paper web is guided in the press device between dry felt webs, the contact pressure is reduced and gentle drying is ensured. In order to maintain optimal germination capacity, the paper web's own temperature should not exceed about 75 ° C.
Dadurch, daß in der Pressenvorrichtung eine Strahlungs- trocknung mit Infrarotlampen vorgenommen wird, wird eine besonders schonende Trocknung der Papierbahn gewährleistet .Because radiation drying with infrared lamps is carried out in the press device, particularly gentle drying of the paper web is ensured.
Um eine homogene Verteilung der Pflanzensamen in dem Faserberei zu gewährleisten, können die Samen je nach Art und Beschaffenheit vor der Zuführung in die Stoffaufberei- tung vorgequellt werden. Dabei ist es vorteilhaft, daß die Samen aus einem separaten Behälter, der ein Rührwerk aufweist, mittels einer Dosierpumpe der Stoffaufbereitung zugeführt werden.In order to ensure a homogeneous distribution of the plant seeds in the fiber processing, the seeds can, depending on the type and nature, be pre-swelled before being fed into the stock preparation. It is advantageous that the seeds are fed from a separate container, which has an agitator, to the stock preparation by means of a metering pump.
In vorteilhafter Weise können die keimfähigen Samen mit Wuchs- und/oder Düngestoffen vorbehandelt werden. Die Wuchs- und/oder Düngestoffe können auch bei der Stoffauf- bereitung dem Faserbrei direkt zugegeben werden.The germinable seeds can advantageously be pretreated with growth and / or fertilizers. The growth and / or fertilizers can also be added directly to the pulp during stock preparation.
Um die Druck- und/oder Temperaturbeständigkeit zu erhöhen, können die keimfähigen Pflanzensamen mit einem Mantelstoff, der aus Stoffkomponenten wie z. B. Farben, Füllstoffe, Bindemittel etc. besteht, umhüllt werden. In vorteilhafter Weise weist die Trockenvorrichtung vier beheizte Zylinder auf, über die die Papierbahnen mittels zweier Filzbahnen geleitet werden. Dabei kann es für eine schonende Trocknung vorteilhaft sein, daß lediglich der dritte und der vierte Zylinder beheizt werden. Die Zylinder können auch unterschiedlich beheizt werden, wobei die maximale Temperaturdifferenz ca. 65 % beträgt und die untere Temperaturgrenze bei ca. 70 °C liegt.In order to increase the pressure and / or temperature resistance, the germinable plant seeds can be coated with a material that consists of components such as. B. colors, fillers, binders, etc., are wrapped. The drying device advantageously has four heated cylinders, over which the paper webs are guided by means of two felt webs. It can be advantageous for gentle drying that only the third and fourth cylinders are heated. The cylinders can also be heated differently, with the maximum temperature difference being around 65% and the lower temperature limit around 70 ° C.
Um eine optimale Bedruckbarkeit mit den bekannten Druckverfahren zu gewährleisten, weist die Oberfläche des keimfähigen Papiers einen Rauhtiefewert von ca. 360 μm auf. Die Grammatur des keimfähigen Papiers kann dabei in etwa 150 bis 400 g/m2 betragen.In order to ensure optimal printability with the known printing processes, the surface of the germinable paper has a roughness depth of approx. 360 μm. The grammage of the germinable paper can be approximately 150 to 400 g / m 2 .
Untersuchungen haben ergeben, daß auch die Recyclier- barkeit gemäß der DIN für die Kategorien 1 (geeignet für die Herstellung von deinkte Altpapierstoff) und für die Kategorie 2 (Altpapier für die Herstellung von Verpak- kungspapier) erfüllt werden.Studies have shown that the recyclability according to DIN is also fulfilled for categories 1 (suitable for the production of deinked waste paper) and for category 2 (waste paper for the production of packaging paper).
Im folgenden wird unter Bezugnahme auf die Zeichnung ein Aαsführungsbeispiel der Erfindung näher erläutert .An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.
Es zeigt :It shows :
Fig. 1 den schematischen Ablauf des erfindungsgemäßen Verfahrens .Fig. 1 shows the schematic flow of the method according to the invention.
In Fig. 1 ist der Verfahrensablauf für die maschinelle Herstellung eines keimfähigen Papiers am Beispiel einer Rundsiebpapiermaschine für die Rollenproduktion dargestellt. Es sollte deutlich sein, daß auch andere Papierherstellungsprozesse, wie z.B. die Bogenproduktion, sowie auch andere Papiermaschinen, wie z.B. die Langsiebpapiermaschine für die Anwendung des Verfahrens geeignet sind.In Fig. 1, the process flow for the mechanical production of a germinable paper is shown using the example of a circular paper machine for roll production. It should be clear that other paper making processes, such as sheet production, as well other paper machines, such as the Fourdrinier paper machine, are also suitable for the application of the method.
Mit 1 ist die Stoffaufbereitung bezeichnet, in der ein Faserbrei 2 gebildet wird. Durch Zumischung verschiedener Hilfsstoffe in gelöster und ungelöster Form werden die späteren Papiereigenschaften zusätzlich beeinflußt.1 denotes the stock preparation in which a pulp 2 is formed. The subsequent paper properties are additionally influenced by admixing various auxiliary substances in dissolved and undissolved form.
In vorteilhafter Weise werden keimfähige Pflanzensamen 3, die sich in einem separaten Behälter 4 befinden, der ein Rührwerk 5 aufweist, vorgequellt. Mittels einer Pumpe 6 werden die Pflanzensamen dem Faserbrei 2 zugeführt. Die vorgequellten Samen verteilen sich dann homogen in dem Faserbrei 2.In an advantageous manner, germinable plant seeds 3, which are located in a separate container 4, which has an agitator 5, are pre-swollen. The plant seeds are fed to the pulp 2 by means of a pump 6. The pre-swollen seeds are then distributed homogeneously in the pulp 2.
Der Faserbrei 2 mit den keimfähigen Pflanzensamen 3 wird dann einer Maschinenbütte 7 zugeleitet, die zumindest einen Rundsiebzylinder 8 aufweist, der in den Faserbrei eingetaucht ist. Bei der Drehung des Rundsiebes 8 setzt sich der Papierstoff außen auf das Sieb ab, während das Wasser durch das Sieb nach innen abläuft .The pulp 2 with the germinable plant seeds 3 is then fed to a machine chest 7, which has at least one circular sieve cylinder 8 which is immersed in the pulp. When the circular sieve 8 rotates, the paper stock settles on the outside of the sieve, while the water runs through the sieve inwards.
Der Papierstoff wird einer Filzbahn 9 zugeführt, um dann in der Pressenvorrichtung 10, die die Filzbahnen 11 und 12 aufweist, gepreßt zu werden. Die Anpreßkraft pro Bahnbreite sollte dabei 25 kp/cm nicht überschreiten. Im Bereich der Pressenvorrichtung 10 können Infrarotlampen 13 vorgesehen sein, die die geformte Papierbahnen 14 schonend vortrocknen.The paper stock is fed to a felt web 9, in order then to be pressed in the press device 10, which has the felt webs 11 and 12. The contact pressure per web width should not exceed 25 kp / cm. Infrared lamps 13 can be provided in the area of the press device 10, which gently pre-dry the shaped paper webs 14.
Die Papierbahn 14 wird dann der Trockenvorrichtung 15 zugeführt, die im wesentlichen vier beheizte Zylinder 16,17,18,19, zwei umlaufende Filzbahnen 20,21 und Umlenkrollen 23 aufweist. Dabei werden die Zylinder der Trocken- Vorrichtung auf eine durchschnittliche Temperatur T von 75 °C bis 130 °C beheizt und die Papierbahn wird mit einer Geschwindigkeit v von 3 m/min bis 8 m /min durch die Trockenvorrichtung 15 geführt. Das Zahlenverhältnis zwischen der Temperatur T in °C und der Papierbahngeschwindigkeit v in m/min beträgt dabei ungefähr 15 bis 23.The paper web 14 is then fed to the drying device 15, which essentially has four heated cylinders 16, 17, 18, 19, two revolving felt webs 20, 21 and deflection rollers 23. The cylinders of the drying The device is heated to an average temperature T of 75 ° C. to 130 ° C. and the paper web is guided through the drying device 15 at a speed v of 3 m / min to 8 m / min. The numerical ratio between the temperature T in ° C and the paper web speed v in m / min is approximately 15 to 23.
Im folgenden werden verschiedene Parameterkombinationen, die diesen Anforderungen genügen, exemplarisch dargestellt:Various parameter combinations that meet these requirements are shown below as examples:

Number ratio 20 v = 5 m / min, T = 95 ° C = »number ratio 19 v = 6 m / min, T = 110 ° C = number ratio 18.3 v = 7 m / min, T = 120 ° C => number ratio 17.1 v = 8 m / min, T = 130 ° C => numerical ratio 16.2.
Die Temperaturen beziehen sich auf das Erreichen des Endtrockengehaltes, der nötig ist, um eine Papierqualität zu gewähleisten, die den Anforderungen an heutige Druckerzeugnisse genügt. Es ist auch möglich, nur den dritten Zylinder 18 und den vierten Zylinder 19 zu beheizen. Dabei können die Zylinder 18,19 auch in unterschiedlichen Temperaturkombinationen beheizt werden. Beispiel:The temperatures refer to reaching the final dry content, which is necessary to ensure a paper quality that meets the requirements of today's printed products. It is also possible to heat only the third cylinder 18 and the fourth cylinder 19. The cylinders 18, 19 can also be heated in different temperature combinations. Example:
