Description

Verfahren und Vorrichtung zur Applikation eines Textilhilfsnnittels bei der Verfestigung von Geotextilien mittels eines hydrodynamischen VerfestigungsverfahrensMethod and device for applying a textile auxiliary agent in the consolidation of geotextiles by means of a hydrodynamic consolidation method
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Applikation eines Textilhilfsnnittels, im wesentlichen einer Avivage bei der Verfestigung von Geotextilien mittels eines hydrodynamischen Verfestigungsverfahrens.The invention relates to a method and a device for applying a textile auxiliary agent, essentially a finishing agent for the consolidation of geotextiles by means of a hydrodynamic consolidation method.
Die Verwendung von Textilhilfsmitteln, also einer sogenannten Avivage bei derThe use of textile auxiliaries, a so-called finish at
Verfestigung von aus Stapel- oder Endlosfasern bestehenden Vliesen ist bekannt.Solidification of nonwovens consisting of staple or continuous fibers is known.
Derartige Textilhilfsmittel verringern die Reibung zwischen den Fasern und erlauben so eine definierte und verbesserte Verfestigung der Vliese.Such textile auxiliaries reduce the friction between the fibers and thus allow a defined and improved consolidation of the nonwovens.
Üblicherweise werden diese Textilhilfsmittel, unabhängig von der angewandten Verfestigungsmethode, also mechanische Verfestigung durch Vernadeln oder hydrodynamische Verfestigung direkt auf die zu verfestigenden Fasern aufgebracht und wirken an der Oberfläche der Fasern sozusagen als Schmiermittel für das leichtere und reibungsarme Durchdringen der Nadeln im Vernadelungsprozess bzw. für das leichtere Gleiten der Fasern auch in hydrodynamischen Verfestigungsprozessen.These textile auxiliaries are usually applied directly to the fibers to be consolidated, regardless of the consolidation method used, i.e. mechanical consolidation by needling or hydrodynamic consolidation, and act on the surface of the fibers as a kind of lubricant for easier and less frictional penetration of the needles in the needling process or for that easier sliding of the fibers even in hydrodynamic consolidation processes.
Hydrodynamische Verfestigungsverfahren sind bekannt und beispielsweise für unterschiedlichste Faserarten in der EP -A 0 896 080, EP-A 101 064, EP-A 0 900 295, EP - A 0967 315, EP-A 0859 076, EP-A 0 841 424, EP 0 727 517 und der EP - A 0 751 249 beschrieben.Hydrodynamic consolidation processes are known and for example for a wide variety of fiber types in EP-A 0 896 080, EP-A 101 064, EP-A 0 900 295, EP-A 0967 315, EP-A 0859 076, EP-A 0 841 424, EP 0 727 517 and EP - A 0 751 249.
Zur Verringerung der Faser/Faserreibung und zur Erreichung einer gleichmäßigen Verfestigung muss das Textilhilfsmittel gemäß der derzeit vertretenen Ansicht des Fachmanns sehr gleichmäßig und mit ausreichenderIn order to reduce the fiber / fiber friction and to achieve a uniform consolidation, the textile auxiliary must, according to the currently held view of the person skilled in the art, be very uniform and with sufficient
BESTATIGUNGSKOPIE Flächendeckung auf die Oberfläche aufgebracht werden um einen gleichmäßigen Erfolg sicherzustellen.BESTATIGUNGSKOPIE Coverage must be applied to the surface to ensure even success.
Aufgabe der Erfindung war es, ein Verfahren zur Aufbringung des Textilhilfsmittels bei der Verfestigung von Vliesen mittels eines hydrodynamischen Verfahren bereitzustellen, bei dem die gewünschte Wirkung des Textilshilfsmittel ohne aufwendige Aufbringungsverfahren eintritt und eine gleichmäßige Verfestigung erzielt werden kann.The object of the invention was to provide a method for applying the textile auxiliary during the consolidation of nonwovens by means of a hydrodynamic method, in which the desired effect of the textile auxiliary occurs without complex application processes and a uniform consolidation can be achieved.
Es konnte nun überraschenderweise gefunden werden, dass eine Aufbringung des Textilhilfsmittels mit ausgezeichneter Gleichmäßigkeit und ohne Wirkungsverlust durch einfache Zudosierung des Textilhilfsmittels zum Wasserstrahl erfolgen kann.It has now surprisingly been found that the textile auxiliary can be applied with excellent uniformity and without loss of effectiveness by simply metering the textile auxiliary into the water jet.
Gegenstand der Erfindung ist daher ein Verfahren zur Aufbringung eines Textilshilfsmittel in einem hydrodynamischen Verfestigungsverfahren, dadurch gekennzeichnet, dass das Textilhilfsmittel direkt in das zur hydrodynamischen Verfestigung verwendete Fluid dosiert wird, bevor das Fluid aus den Hochdruckkapillaren austritt. Vorzugsweise wird das Textilhilfsmittel im Niederdruckteil des Verfahrens zudosiert.The invention therefore relates to a method for applying a textile auxiliary in a hydrodynamic consolidation process, characterized in that the textile auxiliary is metered directly into the fluid used for hydrodynamic consolidation before the fluid emerges from the high-pressure capillaries. The textile auxiliary is preferably metered in in the low-pressure part of the process.
Geeignete Textilhilfsmittel sind dem Fachmann bekannt und im Handel erhältlich. Es können alle zur Avivierung von Fasern bekannten Textilhilfsmittel verwendet werden.Suitable textile auxiliaries are known to the person skilled in the art and are commercially available. All textile auxiliaries known for the finishing of fibers can be used.
Das Textilhilfsmittel wird direkt in das Fluid eingebracht und nicht auf die Oberfläche des zu verfestigenden Vlieses. Mit dem Fluid wird das Textilhilfsmittel gleichmäßig in auf und durch das zu verfestigende Fasergebilde transportiert. Durch den Fluidaustrag mit dem feuchten Produkt, muß sowohl das Fluid, als auch das Textilhilfsmittel kontinuierlich nachdosiert werden, damit sowohl die Fluidmenge als auch die Konzentration des Textilhilfsmittels konstant bleibt. Eine Überprüfung und Korrektur der Konzentration ist durch Messung des Brechungsindexes leicht möglich.The textile auxiliary is introduced directly into the fluid and not on the surface of the nonwoven to be consolidated. With the fluid, the textile aid is transported evenly in and through the fiber structure to be consolidated. Due to the fluid discharge with the moist product, both the fluid and the textile auxiliary must be continuously metered in, so that both the amount of fluid and the concentration of the textile auxiliary remains constant. It is easy to check and correct the concentration by measuring the refractive index.
Überraschenderweise zeigt sich dabei, dass im Gegensatz zu der bisher von de Fachmann vertretenen Ansicht, auch bei Zudosierung des Textilhilfsmittels in das zur hydrodynamischen Verfestigung verwendete Fluid eine gleichmäßige verbesserte Verfestigung erreicht werden kann.Surprisingly, it turns out that, in contrast to the view previously held by the skilled worker, even if the textile auxiliary is metered into the fluid used for hydrodynamic consolidation, a uniformly improved consolidation can be achieved.
Die Menge des zudosierten Textilhilfsmittels ist abhängig von derThe amount of textile auxiliaries added depends on the
Zusammensetzung des Textilhilfsmittels, den Verfahrensparametern der hydrodynamischen Verfestigung und der Art des zu verfestigenden Vlieses, insbesondere der Fasereigenschaften, Fasertextur und den Eigenschaften, die das Vlies nach der Verfestigung aufweisen soll.Composition of the textile auxiliary, the process parameters of the hydrodynamic consolidation and the type of nonwoven to be consolidated, in particular the fiber properties, fiber texture and the properties that the nonwoven should have after consolidation.
Das zu verfestigende Vlies kann aus Stapel- oder Endlosfasern bestehen.The fleece to be consolidated can consist of staple or continuous fibers.
Vorzugsweise bestehen die Fasern aus Kunststoffen, wie beispielsweiseThe fibers preferably consist of plastics, such as, for example
Polypropylen, Polyethylen, Polyamid, Polyester oder aus Mischungen derselben.Polypropylene, polyethylene, polyamide, polyester or mixtures thereof.
Ferner können die Vliese auch Bikomponentenfasern aufweisen oder zurFurthermore, the nonwovens can also have bicomponent fibers or for
Gänze aus derartigen Fasern bestehen.Entirely consist of such fibers.
Die Vliese können aber auch Anteile an natürlichen Fasern wie Cellulose,The nonwovens can also contain natural fibers such as cellulose,
Hanf, Sisal, Kokos, Kenaf und dergleichen enthalten.Contain hemp, sisal, coconut, kenaf and the like.
Die Fasern können jeweils unterschiedliche Texturen und/oder Faserquerschnitte aufweisen.The fibers can each have different textures and / or fiber cross sections.
Ferner können auch mehrere Vliese durch das erfindungsgemäße Verfahren miteinander verbunden und verfestigt werden.Furthermore, several nonwovens can also be connected to one another and consolidated by the method according to the invention.
Dazu werden 2 oder mehrere unverfestigte oder vorfestigte Vliese übereinander abgelegt und anschließend durch ein hydrodynamisches Verfestigungsverfahren unter Zudosierung des Textilhilfsmittels miteinander verbunden. Zur Durchführung des Verfahrens wird das gewählte Textilhilfsmittel vorzugsweise in einem Vorlagebehälter bereitgestellt und über eine Zuleitung zum Wasserstrahlsystem der hydrodynamischen Verfestigungseinrichtung kontinuierlich eingebracht. Vorzugsweise ist die Dosiereinrichtung am Vorlagebehälter situiert. Zur Regelung des Zuflusses werden im allgemeinen über eine geeignete Steuereinrichtung gesteuerte stufenlos regelbare Dosierpumpen verwendet. Die gleichmäßige Verteilung des Textilhilfsmittels im Fluid wird durch eine Mischeinrichtung gewährleistet.For this purpose, two or more unconsolidated or pre-consolidated nonwovens are placed on top of one another and then connected to one another by a hydrodynamic consolidation process with the addition of the textile auxiliary. To carry out the method, the selected textile auxiliary is preferably provided in a storage container and continuously introduced via a feed line to the water jet system of the hydrodynamic consolidation device. The metering device is preferably located on the storage container. In order to regulate the inflow, infinitely variable metering pumps controlled by a suitable control device are generally used. The uniform distribution of the textile auxiliaries in the fluid is ensured by a mixing device.
Durch das beschriebene Verfahren kann auf einfache Weise eine gleichmäßige höhere und einstellbare Verfestigung des Vlieses durch hydrodynamisches Verfahren erreicht werden. Using the described method, a uniformly higher and adjustable consolidation of the fleece can be achieved in a simple manner by means of a hydrodynamic method.

Ein im spun lace Verfahren aus Polypropylengranulat hergestelltes Vlies wurde hydrodynamisch verfestigt, wobei beim ersten Muster kein Textilhilfsmittel, beim zweiten Muster jedoch ein Textilhilfsmittel in den Wasserkreislauf dosiert wurde:A fleece made from polypropylene granulate using the spun lace process was hydrodynamically consolidated, with no textile auxiliary in the first sample, but a textile auxiliary in the second sample being metered into the water cycle:
