Description

Trägervliese sind in der Industrie für vielfältige Anwendungszwecke bekannt. Das wesentliche ist, daß sie den gewünschten Eigenschaften zum dauerhaft Tragen des jeweiligen Produktes genügen. Aus diesem Grunde werden diese Vliese im allgemeinen aus Stapelfasern hergestellt und dann chemisch und/oder mechanisch verfestigt. Unter chemischer Verfestigung ist das innige Vermischen des Vlieses mit einem Bindemittel zu verstehen, das nach einem Wärmebehandlungsvorgang die Fasern des Vlieses fest miteinander verbindet. Es können dem Vlies auch thermoplastische Bindefasern beigemischt werden, die nach dem Schmelzvorgang unter Hitzeeinwirkung die nicht geschmolzenen Fasern punktweise verkleben. Die mit diesen Verfahren herstellbaren Trägervliese haben die geforderte Festigkeit, jedoch sind sie teuer in der Herstellung wegen der notwendigen Bindemittel oder der notwendigen Schmelzfasern.Backing nonwovens are known in the industry for a variety of applications. The the essential thing is that they have the desired properties for permanent wear of the each product are sufficient. For this reason, these fleeces are generally made from staple fibers and then chemically and / or mechanically solidified. The intimate mixing of the nonwoven with is under chemical consolidation to understand a binder that after a heat treatment process Fibers of the fleece firmly bonded together. It can also be the fleece thermoplastic binding fibers are added after the melting process glue the unmelted fibers under heat. With Backing webs that can be produced by this method have the required strength, however they are expensive to manufacture because of the necessary binders or the necessary melt fibers.

Unter mechanischer Verfestigung eines Vlieses aus Stapelfasern oder Endlosfilamenten ist die mechanische Vernadelung zu verstehen. Aber auch diese Vliese sind mit einem Dispersionsbinder zu versehen, da ansonsten die notwendige Festigkeit nicht erreichbar ist. Bei der mechanischen Vernadelung ist es insbesondere von Nachteil, daß die einzelnen Fasern durch die Nadeln verletzt werden, gleichgültig welche Art von Faser oder ob nun Endlosfasern oder Stapelfasern mechanisch vernadelt werden. Dies ist auch ein Grund dafür, daß bei der mechanischen Vernadelung die erforderliche Festigkeit zunächst nicht erreicht wird. Dieses Problem ist zwar zu beheben durch den Einsatz von chemischen Bindern, jedoch sind diese auch nachteilig wegen der späteren schlechteren Penetrationsmöglichkeit. Das Acrylatharz behindert die intensive, auch durchdringende Beschichtung mit Bitumen im Falle der Herstellung von z. B. Bitumendachbahnen. With mechanical consolidation of a fleece made of staple fibers or Endless filaments are to be understood as mechanical needling. But this too Nonwovens are to be provided with a dispersion binder, otherwise the necessary ones Strength is not attainable. With mechanical needling it is particularly disadvantageous that the individual fibers are injured by the needles, indifferent what type of fiber or whether continuous fibers or staple fibers mechanically needled. This is also a reason why mechanical Needling the required strength is not initially achieved. This problem can be remedied by using chemical binders, but they are also disadvantageous because of the later poorer possibility of penetration. The Acrylic resin hinders the intensive, also penetrating coating with bitumen in the case of the production of e.g. B. bitumen roofing membranes.  

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und nach dem Verfahren das wünschenswerte Produkt zu entwickeln, mit dem preiswerter ein hochfestes Vlies wie insbesondere Trägervlies hergestellt werden kann, das für z. B. Bitumenbahnen die geforderte Festigkeit hat, aber mit keinem Bindemittel, keiner Bindefaser versehen ist.The invention has for its object a method and according to the method to develop a desirable product with which a high-strength fleece such as in particular carrier fleece can be produced, which for z. B. bitumen membranes has the required strength, but is not provided with any binding agent or binding fiber.

Zur Lösung der gestellten Aufgabe ist nach der Erfindung vorgesehen, daß Endlosfilamente unmittelbar nach ihrer Herstellung zu einem gleichmäßig dicken Vlies auf einem Endlossieb abgelegt und dann hydrodynamisch vernadelt werden zur Herstellung eines hochfesten Vlieses. Die Ablage der Endlosfasern kann mit der heutigen Technik sicher derart erfolgen, daß eine im wesentlichen gleichmäßige Festigkeit in den zwei Flächendimensionen erzielbar ist. Wird dann dieses Vlies, werden dann diese Filamente mit der Wasservernadelung verletzungsfrei in der dritten Dimension verlagert, miteinander verhakt, so entsteht die gewünschte hohe Festigkeit, ohne daß die teuren und bei der Weiterbearbeitung des Vlieses auch nachteiligen Binder gebraucht werden. Das Vlies ist weiterhin hoch luftdurchlässig und kann, weil keine Netzmittel bei der Herstellung des verfestigten Vlieses verwendet sind, besser mit einer Nutzschicht durchdrungen, penetriert werden. Es kann sogar gegenüber dem Verfahren nach dem Stand der Technik ein höherer Anteil an Bitumen in das Vlies eingegeben werden, ohne daß die Elastizität des Vlieses verloren geht. Vorteilhaft ist dabei auch die innige Vermischung des Bitumens durch die jetzt vorhandenen Poren des Vlieses, was Folgen für die Nicht-Spaltfähigkeit des Vlieses insbesondere bei niedrigen Temperaturen hat.To solve the problem it is provided according to the invention that Continuous filaments immediately after they are made into a uniformly thick fleece placed on an endless screen and then needled hydrodynamically to Production of a high-strength fleece. The filing of the continuous fibers can be done with the today's technology must be done in such a way that a substantially uniform Strength can be achieved in the two surface dimensions. Then this fleece, these filaments are then injured with the water needling in the third Dimension shifted, hooked together, this creates the desired high strength, without the expensive and also disadvantageous in the further processing of the fleece Binder are needed. The fleece is still highly breathable and can because no wetting agents are used in the production of the consolidated nonwoven, better to be penetrated with a wear layer. It can even face that State-of-the-art methods include a higher proportion of bitumen in the fleece can be entered without losing the elasticity of the fleece. It is advantageous the intimate mixing of the bitumen through the pores now present of the fleece, which in particular has consequences for the non-cleavability of the fleece has low temperatures.

Es ist zur Gewährleistung einer Dimensionsstabilität zweckmäßig, das vernadelte Endlosfaservlies vor einer Beschichtung zu fixieren.It is useful to ensure dimensional stability, the needled To fix continuous fiber fleece before coating.

Die Nutzbeschichtung kann z. B. eine Bitumenbeschichtung sein, oder dieses Trägervlies dient als Matrixbahn für spätere Tuftingveredelung oder einer Beschichtung mit Weichmachern. Letzteres hat in der softener-fabric-Industrie den Vorteil, daß ein solches Vlies nicht flust.The useful coating can e.g. B. be a bitumen coating, or this Backing fleece serves as a matrix sheet for later tufting finishing or one Coating with plasticizers. The latter has the in the softener fabric industry Advantage that such a fleece does not flow.

Diese Vliese können auch aus endlosen PETP-Fasern hergestellt werden, weil damit nicht nur hochfeste, sondern auch thermostabile Vliese erzielbar sind. These fleeces can also be made from endless PETP fibers because of that not only high-strength, but also thermostable nonwovens can be achieved.  

Beispiel 1example 1

Ein 45 g/m2 Vlies aus endlosen PE-Fasern wurde zur Verfestigung hydrodynamisch vernadelt und erhielt eine Festigkeit von 133 N/5 cm in Längsrichtung und 109 N/5 cm in Querrichtung bei einer Dehnung von 68 bzw. 75%. Dies ergibt eine Längsfestigkeit von 3,0 N/5 cm pro g/m2. Diese Festigkeit reicht aus, um z. B. als Bitumenbahn die Basis zu bieten.A 45 g / m 2 nonwoven made of endless PE fibers was needled hydrodynamically for consolidation and obtained a strength of 133 N / 5 cm in the longitudinal direction and 109 N / 5 cm in the transverse direction with an elongation of 68 and 75%. This gives a longitudinal strength of 3.0 N / 5 cm per g / m 2 . This strength is sufficient to z. B. to offer the basis as a bitumen membrane.

Beispiel 2Example 2

Ein 145 g/m2 Vlies aus endlosen PE-Fasern wurde zur Verfestigung beidseitig hydrodynamisch vernadelt und erhielt eine Festigkeit vom 530 N/5 cm in Längsrichtung bei einer Dehnung von 75%. Dies ergibt eine Längsfestigkeit von 3,7 N/5 cm pro g/m2.A 145 g / m 2 nonwoven made of endless PE fibers was needled hydrodynamically on both sides for strengthening and obtained a strength of 530 N / 5 cm in the longitudinal direction with an elongation of 75%. This results in a longitudinal strength of 3.7 N / 5 cm per g / m 2 .
