Abstract

A nonwoven material with two layers consists of a spunbonded or a nonwoven material on which a carded staple fibre mat is placed. The mat is joined to the spunbonded or nonwoven material by needling. The nonwoven material is made wholly or partially of continuous bicomponent filaments. The spunbonded material can consist of polyamide, polyester, polyethylene or poplypropylene. Akzo-Enka's Colback with a polyester core and a polyamide covering is a partic. suitable for the nonwoven material. ADVANTAGE - The material can be used in a wide variety of applications, including as filter fabric.

Description

Die Erfindung betrifft einen zweischichtigen Vliesstoff, bei welchem auf einem Spinnvlies (spun-bonded Vlies) oder einem Vliesstoff ein gekrempeltes Kurzfasergelege (Stapelfaser­ vlies) angeordnet ist und das Spinnvlies bzw. der Vliesstoff mit dem Kurzfasergelege durch Vernadeln verbunden ist.The invention relates to a two-layer nonwoven, at which on a spun-bonded fleece or one Nonwoven a carded short fiber fabric (staple fiber fleece) is arranged and the spunbonded nonwoven is connected to the short fiber fabric by needling.

In Ausgestaltung kann das Spinnvlies bzw. der Vliesstoff ganz oder teilweise aus Bikokomponenten-Endlos-Filamenten bestehen.In one embodiment, the spunbonded nonwoven or the nonwoven can wholly or partly of endless filament bicomponent consist.

Die Erfindung betrifft auch ein Verfahren zum Herstellen des zweischichtigen Vliesstoffes, bei welchem erfindungsgemäß auf einem Spinnvlies (spun-bonded Vlies) oder einem Vlies­ stoff ein gekrempeltes Kurzfasergelege (Stapelfaservlies) angeordnet wird und das Spinnvlies bzw. der Vliesstoff anschließend mit dem Kurzfasergelege vernadelt wird.The invention also relates to a method for producing the two-layer nonwoven, in which according to the invention on a spun-bonded fleece or a fleece a carded short fiber fabric (staple fiber fleece) is arranged and the spunbonded nonwoven is then needled with the short fiber fabric.

Unter Spinnvlies wird ein (textiles) Flächengebilde aus Filamenten verstanden, das aus Polymeren - gegebenenfalls nach einem in die Faserherstellung integrierten Verfahren - hergestellt wird. Dazu können alle Polymere, die sich nach dem Schmelz- oder Trockenspinnverfahren verarbeiten lassen, wie z. B. Polyamide, Polyester und Polyolefine, wie Poly­ äthylen, Polypropylen, eingesetzt werden. Spinnvliese können auch nach einem Naßspinnverfahren hergestellt werden. Die verfestigten Spinnvliese werden Spinnvlies­ stoffe genannt. Zur weiteren Beschreibung von Spinnvliesen und Spinnvliesstoffen, die dem Fachmann an sich bekannt sind, wird beispielsweise auf das Buch "Vliesstoffe" herausgegeben von Joachim Lünenschloß und Wilhelm Albrecht; Georg Thieme-Verlag Stuttgart - New York, 1982; Seiten 106 ff verwiesen.Spunbonded nonwoven is understood to mean a (textile) fabric made of filaments, which is made from polymers - optionally by a process integrated in the fiber production. For this purpose, all polymers that can be processed by the melt or dry spinning process, such as. B. polyamides, polyesters and polyolefins, such as poly ethylene, polypropylene, are used. Spunbonded nonwovens can also be produced using a wet spinning process. The consolidated spunbonded fabrics are called spunbonded fabrics. For a further description of spunbonded nonwovens and spunbonded nonwovens, which are known per se to the person skilled in the art, the book "Nonwovens" is published by Joachim Lünenschloß and Wilhelm Albrecht; Georg Thieme-Verlag Stuttgart - New York, 1982 ; Pages 106 ff.

Das erfindungsgemäße Zweischichtgebilde ist ein Produkt mit hervorragenden Eigenschaften, das für die unterschied­ lichsten Verwendungszwecke bestens geeignet ist. So kann der zweischichtige Vliesstoff mit Vorteil beispielsweise als Filtertuch eingesetzt werden.The two-layer structure according to the invention is a product with excellent properties that make the difference most suitable uses. So he can two-layer nonwoven with advantage, for example, as Filter cloth can be used.

Ein für die Herstellung des erfindungsgemäßen zwei­ schichtigen Vliesstoffes besonders geeigneter Vliesstoff ist unter dem Namen Colback® der Firma Akzo-Enka bekannt, das aus Kern-Mantel-Bikomponenten-Endlosfilamenten besteht mit einem Kern aus Polyester und einem Mantel aus Polyamid 6.A nonwoven that is particularly suitable for the production of the two-layer nonwoven according to the invention is known under the name Colback® from Akzo-Enka, which consists of core-sheath bicomponent continuous filaments with a core made of polyester and a sheath made of polyamide 6 .
