Abstract

Es ist bekannt, auf ein Stapelfaservlies fortlaufend endlos gesponnene Filamente abzulegen und dieses Kompositvlies zur Verfestigung wasserzuvernadeln. Dieses dabei erzeugte Vlies ist sehr flach und nicht voluminös. Es wird vorgeschlagen, die Endlosfasern als Bi- oder Segmentfasern auszubilden, also ein Komposit aus Stapelfaservlies mit einem Endlosfaservlies zu bilden, deren Fasern diese Bikomponentenfasern oder ähnliche sind, die später nach der Verfestigung zum Schrumpfen veranlasst werden.It is known to continuously deposit endlessly spun filaments on a staple fiber nonwoven and to water needle this composite nonwoven for consolidation. This fleece is very flat and not voluminous. It is proposed to design the continuous fibers as bi- or segment fibers, that is to say to form a composite of staple fiber fleece with an endless fiber fleece, the fibers of which are bicomponent fibers or the like, which are subsequently caused to shrink after solidification.

Description

Durch die DE-A-19 52 276 ist ein wasservernadeltes Kompositvlies aus Krempelvlies und Endlosfaservlies bekannt. Die Endlosfasern können in einem vorher gefertigten Faservlies als aufgerollte Bahnware vorgelegt oder unmittelbar auf ein Endlosband oder auf das Stapelfaservlies abgelegt werden, wie es in der WO 00/77286 beschrieben ist. Es ist zweckmäßig, die beiden Vliese vor der hydrodynamischen Vernadelung miteinander zu verpressen.DE-A-19 52 276 is a water-needled composite fleece made of carded fleece and continuous fiber fleece known. The continuous filaments can be made in a previously made Fiber fleece presented as a rolled web or directly on an endless belt or placed on the staple fiber fleece, as described in WO 00/77286 is described. It is advisable to place the two fleeces in front of the hydrodynamic Press needles together.

Durch den Pressvorgang und auch durch die Wasservernadelung wird das Komposit zwar gut verfestigt, es wird aber auch sehr flach. Der Erfindung liegt die Aufgabe zugrunde, bei einem Komposit aus einem Stapelfaservlies plus einem Endlosfaservlies, dessen Fasern insbesondere kontinuierlich auf das Stapelfaservlies abgelegt sein sollten, trotz dieser Behandlung so zu gestalten, dass ein voluminöses Vlies erhalten werden kann.The composite becomes through the pressing process and also through the water needling solidified well, but it also becomes very flat. The object of the invention is to achieve this the basis for a composite made from a staple fiber fleece plus one Endless fiber fleece, the fibers of which are continuously applied to the staple fiber fleece should be filed in spite of this treatment in such a way that a voluminous Fleece can be obtained.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, dass als Spinnfasern allein oder vermischt mit anderen Endlosfasern Bi- oder ähnliche Mehrkomponentenfasern mit dem Krempelvlies zusammengebracht und dann beide Vliese zur Verfestigung ein- oder beidseitig mit der hydrodynamischen Vernadelung beaufschlagt werden und dabei die Endlosfasern mit den Stapelfasern vermischt werden.To achieve this object, the invention provides that as staple fibers alone or mixed with other continuous fibers with bi- or similar multi-component fibers the carded fleece brought together and then both fleece for consolidation or both sides with the hydrodynamic needling and thereby the continuous fibers are mixed with the staple fibers.

Die Bikomponenten- oder Segmentfasern können beliebiger Art sein. Sie können einen zentrischen Mittelpunkt oder aber auch exzentrische Mittelpunkte haben. Es können Splitfasern sein oder auch ein- oder mehrschalige Filamente. Hier ist z. B. auf die Offenbarung der DE-A-28 58 174 oder 28 56 091 oder die EP-A-0 455 927 oder 0 625 221 zu verweisen. Wichtig ist nur, dass die Fasern bei einer folgenden Wärmebehandlung zumindest teilweise schrumpfen, sich kräuseln, wodurch das gewünschte Volumen des ganzen Vlieses erzeugt wird.The bicomponent or segment fibers can be of any type. You can have one have a central center or eccentric centers. It can Be split fibers or single or multi-layer filaments. Here is z. B. on the Disclosure of DE-A-28 58 174 or 28 56 091 or EP-A-0 455 927 or 0 625 221 to refer. It is only important that the fibers in a following Heat treatment at least partially shrink, curl, causing that desired volume of the entire fleece is generated.
