Abstract

Production of a non-woven tissue from wood pulp on a wet strip is known. The above has a cardboardy, paper-like feel to it. In order to achieve a web with sufficient resilience, the desired wood pulp fibres used to advantage in the hygiene industry for absorbing liquids are thus always mixed with chemical fibres as support fibres. According to the invention, a consolidated tissue with a soft feel and high fluid absorption is obtained by means of needling a non-woven pure wood pulp tissue with water.

Description

Durch die EP-A-0 359 615 ist ein Verfahren zum Bilden einer Warenbahn nur aus Zellulosefasern, wie Wood Pulp, bekannt, das auf dem nassen Wege gebildet und dann nur getrocknet wird. Eine Verfestigung in Sinne einer Verschlingung der Fasern untereinander erfolgt dort nicht.By the EP-A-0 359 615 For example, a method of forming a web of cellulose fibers only, such as wood pulp, is known, which is wet-formed and then merely dried. A solidification in terms of entanglement of the fibers with each other is not there.

Es ist durch die EP-A-0 308 320 bekannt, eine höher verfestigte Warenbahn herzustellen, indem auf eine Warenbahn aus nass gelegten Endlosfilamenten eine heitere Schicht aus bis zu 90 % Wood Pulp vermischt mit Stapelfasern gegeben wird. Beides zusammen wird dann zu Verfestigung hydrodynamisch vernadelt.It is through the EP-A-0 308 320 It is known to produce a highly consolidated web by placing on a web of wet laid filaments a serene layer of up to 90% wood pulp mixed with staple fibers. Both together are then hydrodynamically needled to solidification.

Ein ähnliches Verfahren offenbart die EP-A-0 373 974 , nach der ebenfalls nass gelegte Bahnen aus bis zu 80 % Wood Pulp mit Bahnen jetzt aus Stapelfasern zusammen hydrodynamisch vernadelt werden. Derartige Komposits haben zwar eine höhere Festigkeit, aber die Kapazität zur Aufnahme von Flüssigkeiten ist unbefriedigend.A similar method discloses the EP-A-0 373 974 , according to which also wetted webs of up to 80% wood pulp with webs are now hydrodynamically needled together from staple fibers. Although such composites have a higher strength, but the capacity for receiving liquids is unsatisfactory.

Auf trockenem Wege diese Komposits zu bilden ist ebenfalls bekannt. Im Zusammenhang mit Endlosfasern ist dazu auf die EP-A-0 492 554 zu verweisen, wo ein Zellstoffgehalt bis zu 90 % mit den Endlosfasern wasservernadelt wird.Drying these composites is also known. In connection with continuous fibers is on the EP-A-0 492 554 to point out, where a pulp content up to 90% is water-needled with the continuous fibers.

Im Gegensatz dazu sieht die US-A-6 110 848 ein Komposit als vorteilhaft an, wenn die bis zu 90 % mächtige Wood Pulpschicht eine Unterlage aus einem Vlies aus kardierten Stapelfasern zwischen 30 und 100 mm hat. Ein drittes Vlies aus derartigen Stapelfasern kann auf der Oberseite mit der Wood Pulpschicht in der Mitte das Kompost vervollständigen. Alles zusammen soll hydrodynamisch verfestigt werden.In contrast, the sees US-A-6 110 848 a composite advantageous if the up to 90% thick wood pulp layer has a backing of a nonwoven carded staple fibers between 30 and 100 mm. A third web of such staple fibers can complete the compost on top with the wood pulp layer in the middle. Everything together should be solidified hydrodynamically.

Die EP-A-0 483 816 beschreibt die Wasserstrahlvernadelung einer nass gelegten Woodpulp Bahn.The EP-A-0 483 816 describes the waterjet needling of a wet laid Woodpulp web.

Derartige Komposits sind in manchen Anwendungsfällen vorteilhaft, dennoch nehmen die für notwendig gehaltenen künstlichen Fasern keinerlei Feuchtigkeit auf, weswegen nach einem weiteren Produkt gesucht wird, das ebenfalls eine ausreichende Festigkeit aufweist.Such composites are advantageous in some applications, yet take the necessary artificial fibers considered no moisture, which is why looking for another product, which also has sufficient strength.

Der Erfindung liegt folglich die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Vlieses zu finden, dass eine höchst mögliche Flüssigkeitsaufnahmefähigkeit aufweist und zusätzlich eine genügende Festigkeit, die gewährleistet, das Vlies in den jeweiligen Anwendungsfällen einsetzen zu können.The invention is therefore an object of the invention to find a method for producing a nonwoven fabric that has a very high liquid absorption capacity and in addition a sufficient strength, which ensures to be able to use the fleece in the respective applications.

Es steht jedenfalls fest, dass das Vlies aus Wood Pulp nach einem trockenen Bildungsverfahren, z. B. einem Luftlegeverfahren trocken auf ein Endlosband abgelegt und wie üblich mittels Saugzug auf dem Endlosband verdichtet werden sollte. Dann ist die reine Wood Pulpbahn, also eine aus 100 % Wood Pulpfasern gebildete Warenbahn zur Verfestigung lediglich mit einer hydrodynamischen Vernadelung zu beaufschlagen und anschließend zu trocknen.In any case, it is clear that the non-woven of wood pulp after a dry formation process, eg. As an air laying dry laid on an endless belt and should be compacted as usual by means of induced draft on the endless belt. Then the pure Wood Pulpbahn, ie a fabric web formed from 100% Wood Pulp fibers for solidification only with a hydrodynamic needling and then to dry.

Als Versuchsbedingungen wurde zuerst eine Befeuchtung der Wood Pulpfasern zwischen zwei Endlosbändern mit einem Wasserdruck von 10 bar gewählt. Die eigentliche verfestigende Vernadelung wurde dann ein- oder beidseitig mit nur einem Wasserdruck von 20 bar vorgenommen. Der Wasserdruck sollte nicht zu hoch gewählt werden, vorteilhaft ist ein Druck von 15 - 40 bar. Das zur Unterstürzung gewählte Sieb bei der Vernadelung sollte nur eine geringe Durchlässigkeit von etwa 10 % offene Fläche aufweisen, um einen Pulpverlust zu beherrschen.As a test conditions, a moistening of the wood pulp fibers between two endless belts was first selected with a water pressure of 10 bar. The actual consolidating needling was then done on one or both sides with only a water pressure of 20 bar. The water pressure should not be too high, a pressure of 15 - 40 bar is advantageous. The debulking screen at needling should have only a low permeability of about 10% open area to control pulp loss.

Überraschend wurde festgestellt, dass der befürchtete Wood Pulp Verlust beim Wasservernadeln mit diesen Bedingung ohne große Bedeutung ist. Dieser ist nämlich Gegenstand der WO 01114624 , wo neben der Trägerschicht aus Chemiefasern vor der Aufgabe der Wood Pulpfasern auf die Chemiefaserträgerschicht zunächst eine Schicht aus Meltblownfasern gegeben wird, um den Wood Pulpverlust beim sich anschließenden hydrodynamischen Verfestigen zu mindern.Surprisingly, it was found that the feared Wood Pulp loss in water needling with this condition is of little importance. This is namely the subject of WO 01114624 where, in addition to the carrier layer of chemical fibers before the task of Wood Pulpfasern on the man-made fiber carrier layer, first a layer of meltblown fibers is added to reduce the Wood Pulpverlust during subsequent hydrodynamic solidification.

Die Wood Pulpfasern haben eine Länge von 1 - 5 mm. Die Länge hängt von dem Baum, von der Pflanzenart ab. Ein hier bevorzugtes Vlies sollte jedenfalls Fasern unterschiedlicher Länge aufweisen, vorzugsweise auch längere als 5 mm lange Fasern. Überraschend wurde festgestellt, dass sich auch diese nur kurzen Faserlängen mit der Wasserstrahlverfestigung verwirren lassen, um ein in allen Dimensionen verfestigtes Vlies entstehen zu lassen.The wood pulp fibers have a length of 1 - 5 mm. The length depends on the tree, on the plant species. In any case, a preferred nonwoven should be fibers have different lengths, preferably longer than 5 mm long fibers. Surprisingly, it has been found that even these short fiber lengths can be confused with hydroentanglement in order to produce a nonwoven consolidated in all dimensions.

Das nasse und verfestigte Wood Pulpvlies kann vor dem Trocknen noch mit einem Bindemittel besprüht werden, bevor es dann gleich anschließend getrocknet wird.The wet and solidified Wood Pulpvlies can be sprayed before drying with a binder before it is then immediately dried.

Selbstverständlich kann die Woodpulp-Bahn auch noch nach dem Wasservernadeln mit ändern Fasern vermischt werden oder mit einer anderen Bahn aus ändern Fasern wie Stapel- oder Endlosfasern oder auch natürlichen Fasern verbunden werden.Of course, the wood pulp web can still be mixed after the water needles with other fibers or be connected to another web of different fibers such as staple or continuous fibers or natural fibers.
