Ptttot-AbttUnag Reu/EPtttot-AbttUnag Reu / E Verfahren zur Herstellung von verfestigten Vliesen und MattenProcess for the production of consolidated fleeces and mats

Gegenstand der Erfindung ist ein verfestigtes Vlies oder eine Hatte bestehend aus bzw. enthaltend Zweikomponentenfasern in Kern-Mantel-Struktur.The invention relates to a consolidated fleece or a hat consisting of or containing bicomponent fibers in a core-sheath structure.

Es ist bekannt, Vliese aus natürlichen oder synthetischen Fasern dadurch zu verfestigen, daß bei der Vliesherstellung noch solche Fasern zugesetzt werden, die einen deutlich niedrigeren Schmelzpunkt besitzen als die eigentlich vliesbildenden Fasern. Durch eine Temperaturbehandlung werden die Fasern mit niederem Schmelzpunkt erweicht und dadurch die anderen Fasern punktförmig verklebt. Nach diesem Verfahren werden allerdings die niederschmelzenden Fasern in ihrer Struktur vollständig zerstört und sie tragen außer ihren Eigenschaften als Kleber nicht zum Aufbau des Vlieses mit bei.It is known, nonwovens made of natural or synthetic To solidify fibers by adding fibers that are clearly visible during the manufacture of the nonwoven have a lower melting point than the actual fleece-forming Fibers. The fibers with a low melting point are softened by a temperature treatment and thereby the other fibers are glued in dots. After this process, however, the low-melting fibers are in their structure is completely destroyed and, apart from their properties as adhesives, they do not contribute to the structure of the fleece with at.

Es ist weiter bekannt, Fasern mit einem potentiellen Kleber nachträglich zu umhüllen. Dieser Kleber schmilzt bei Temperatureinwirkung und läuft an den Faserkreuzungsetellen zu Bindepunkten zusammen, wodurch die Verfestigung des Faservlieses bewirkt wird. Weiterhin ist bekannt, Vliese aus Bikomponentenfasern zu erzeugen, wobei in einer'einzigen Faser zwei Komponenten, von welchen die eine einen deutlich niedrigeren Schmelzpunkt besitzt als die andere, nebenein-It is also known to subsequently encase fibers with a potential adhesive. This adhesive melts when exposed to temperature and converges at the fiber crossing points to form bonding points, whereby the solidification of the fiber fleece is effected. It is also known to use nonwovens made from bicomponent fibers to produce, with two components in a single fiber, one of which is clearly one has a lower melting point than the other, adjacent

ander liegen. Bei Temperaturbehandlung erweicht nun die Faserkomponente und bewirkt an den Kreuzungsstellen eine Verklebung. Gleichzeitig tritt aber bei diesem Verfahren eine starke Kräuselung und damit ein Zusammenschrumpfen des Vlieses auf. Das ist speziell bei voluminösen Vliesen nicht erwünscht. .other lie. The temperature treatment now softens the Fiber component and causes a Bonding. At the same time, however, occurs in this procedure a strong crimp and thus a shrinkage of the fleece. This is especially not the case with voluminous fleeces he wishes. .

Es wurde nun gefunden, daß die bisherigen Nachteile umgangen werden können, wenn beim Erspinnen der Faser zwei oder gegebenenfalls mehr Komponenten in Kern-Mantel-Struktur aufgebaut werden. Dabei besitzt die Komponente im Faserkern einen wenigstens 20° höheren Erweichungspunkt als die Komponente im Fasermantel. Bei einer Temperaturbehandlung - gegebenenfalls unter Druck - nach der Vlies- bzw. Mattenbildung wird der Fasermantel plastisch und wirkt als Bindemittel, während der Kern als eigentliche Fasersubstanz in reiner Struktur im fertigen Vlies erhalten bleibt. Die Vlies- oder Mattenbahnen enthalten mindestens 30 Gew.-j6 an Bikomponentenfasern in Kern-Mantel-Struktur. Die so hergestellten Fasern, mit der oben beschriebenen Struktur, können mit beliebigen Titern in reiner Form oder in Mischung mit anderen synthetischen oder natürlichen Fasern zu Vliesen bzw. Matten verarbeitet werden. Der Vorteil dieses Verfahrens liegt darin, daß die Fasern vor der Verarbeitung nicht speziell mit einem potentiellen Binder präpariert werden müssen. Es braucht auch keine Mischung mit Bindefasern hergestellt zu werden. Ferner tritt bei der Temperaturbehandlung keine unerwünschte Veränderung des Faserflors, also auch keine Volumenminderung ein. Es lassen sich beliebige Kombinationen von Kern und Mantel erspinnen, so daß jedem Anwendungszweck.von der Behandlungstemperatur sowie von den physikalischen und chemischen Eigenschaften her Genüge getan werden kann. Bei einer thermischen Behandlung läßt sich aber auch mit dieser Struktur eine gleichzeitige Kräuselung der Kern-Mantel-FasernIt has now been found that the previous disadvantages are avoided can be built up when two or possibly more components in a core-sheath structure when the fiber is spun will. The component in the fiber core has a at least 20 ° higher softening point than the component in the fiber sheath. In the case of a temperature treatment - if necessary under pressure - after the formation of the fleece or mat the fiber sheath is plastic and acts as a binder while the core as the actual fiber substance in a pure structure in the finished fleece is preserved. The fleece or mat webs contain at least 30% by weight of bicomponent fibers in Core-sheath structure. The fibers produced in this way, with the structure described above, with any titers in pure form or in a mixture with other synthetic ones or natural fibers are processed into fleeces or mats. The advantage of this method is that the Fibers do not have to be specially prepared with a potential binder before processing. It also takes no mixture with binding fibers to be made. Furthermore, no undesirable change occurs during the temperature treatment of the pile of fibers, so there is no reduction in volume. Any combination of core and Spin coat, so that every application. From the treatment temperature as well as the physical and chemical properties can be satisfied. At a Thermal treatment can also result in a simultaneous crimping of the core-sheath fibers with this structure

und damit eine Florverdichtung erzielen, wenn Mantel und Kern nicht konzentrisch ersponnen werden. Durch den Grad der Exentrität läßt eich der Kräuselcharakter mit beeinflussen. Als Paserkern werden z. B. Homopolyamide und hochschmelzende Copolyamide oder Mischungen aus beiden eingesetzt, während als Hantel niedrigschmelzende Copolyamide verwendet werden können.and thus achieve pile compaction if the sheath and core are not spun concentrically. The ripple character can be influenced by the degree of eccentricity. As a paserkern z. B. homopolyamides and high-melting copolyamides or mixtures of both are used, while low-melting copolyamides can be used as dumbbells.

Pasern mit dem Titer 6 dtex, der Schnittlänge 60 mm und einer mechanisch aufgebrachten Kräuselung werden in üblicher Weise auf der Krempel mit nachfolgenden] Kreuzleger zu einem Paserflor von etwa 200 g/m aufgearbeitet. Die Pasern bestehen im Kern aus Folyamid-6 (80 #) und iin Mantel (20 #) aus einem Mischpolyamid aus 40 Gew.-Ji Aminocapronsäure und 60 Gew.-Ji Aminoundecansäure. Das Vlies wird während 2 Minuten ohne Druck einer Hitze von 135 0C in einem Düsentrockner ausgesetzt. Dadurch erhält man ein voluminöses, gleichmäßig verfestigtes Vlies, das sich als Gasfilter eignet.Pipes with a titer of 6 dtex, a cutting length of 60 mm and a mechanically applied crimp are worked up in the usual way on the carding machine with a cross-stacker to give a Paser pile of about 200 g / m 2. The fibers consist in the core of Folyamid-6 (80 #) and in the jacket (20 #) of a mixed polyamide of 40 percent by weight of aminocaproic acid and 60 percent by weight of aminoundecanoic acid. The web is exposed in a jet dryer for 2 minutes without pressure to a heat of 135 0 C. This results in a voluminous, uniformly consolidated fleece that is suitable as a gas filter.
