Description

Die Erfindung betrifft ein Verfahren zur Herttellung eines Grundmaterials aus Abfallfasern für die Weiterverarbeitung zu Kunstleder, Filterstoffen U. dgl.The invention relates to a method for producing a base material from waste fibers for further processing to artificial leather, filter fabrics, etc.

Es ist bekannt, derartiges Material durch Imprägnieren von Faserflächengebilden mit Bindemitteln herzustellen. Brauchbare Produkte für obengenannte Zwecke erhält man jedoch nur beim Imprägniere", von Vliesen aus wertvollem Fasermateri'.l bzw. Mischungen.It is known to produce such a material by impregnating fibrous sheet-like structures with binders to manufacture. However, useful products for the above-mentioned purposes are only obtained from Impregnation ", of fleeces made from valuable fiber material or mixtures.

Es ist außerdem bekannt, Faservliese durch Nähwirken zu verfestigen. Solche Nähvliese sind jedoch für Kunstleder ungeeignet wegen ihrer geringen Festigkeit und des nicht lederärmlichen Aussehens infolge des Oberflächencharakters der Textilbindung. Es ist ferner bekannt, genadelte Vliese zu imprägnieren und für die Weiterverarbeitung zu Kunstleder zu verwenden. Man kann jedoch nicht alle Abfallfasern zu Nadelvliesen verarbeiten.It is also known to strengthen nonwovens by sewing. Such sewn nonwovens are, however unsuitable for artificial leather because of their low strength and the non-leathery appearance due to the surface character of the textile weave. It is also known to impregnate needled fleeces and to be used for further processing into artificial leather. However, one cannot do all of them Process waste fibers into needle punched nonwovens.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung obiger Ausgangsmaterialien aus Abfallfasern, also aus beliebigem, billigem Fasermaterial, herauszufinden.The invention is based on the object of a process for the production of the above starting materials to find out from waste fibers, i.e. from any cheap fiber material.

Die Aufgabe wurde so gelöst durch die Kombination folgender, an sich bekannter Schritte, daß man ein loses Vlies aus beliebigen Abfallfasern vernäht, anschließend beidseitig aufrauht und dann mit einem Bindemittel einmal oder mehrfach imprägniert bzw. thermisch oder durch Anlösen der Fasern verfestigt. The object was achieved by the combination of the following steps, known per se, that a loose fleece is sewn from any waste fibers, then roughened on both sides and then with one or more times impregnated with a binding agent or solidified thermally or by partially dissolving the fibers.

Zu diesem Zweck muß ein Vlies aus beliebigem Abfall-Faseraaterial zunächst genäht werden, um ihm für die weitere Verarbeitung genügend Festigkeit zu geben. Dies kann nach bekannten Nähwirkverfahren geschehen. Auch das Einlegen eines filzfähigen Fadenskeletts eignet sich dazu, wobei jedoch die Fäden nicht mit dem Vlies vernäht werden, sondem zwischen Vlieslagen ausgelegt sind. Um die Längsnähte für das Endprodukt unsichtbar in das Innere des Vlieses zu verlegen, wird das Material anschließend nach bekannten Rauhverfahren beidseitig so behandelt, daß der aufgerauhte Flor gleichmäßig auf beiden Seiten erhalten wird ur>d dadurch die Nähte verdeckt. Gleichzeitig erhält man ein voluminöses und weiches Ausgangsmaterial für die weitere Verarbeitung.For this purpose, a fleece made of any waste fiber material must first be sewn to to give it sufficient strength for further processing. This can be done using known stitchbonding methods happen. The insertion of a feltable thread skeleton is also suitable, however the threads are not sewn to the fleece, but rather are laid out between fleece layers. To the Laying longitudinal seams invisible in the interior of the fleece is the material then treated on both sides by known roughing methods so that the roughened pile is uniform preserved on both sides ur> d thereby hides the seams. At the same time you get a voluminous and soft raw material for further processing.

Nach dem Aufrauhen werden die Faserfiächengebilde mit einem üblichen Bindemittel, wie Latex, Acrylatharz oder Polyurethan (Polymere allgemein), imprägniert.After roughening, the fibrous surface structures are coated with a common binding agent such as latex, Acrylic resin or polyurethane (polymers in general), impregnated.

Durch Wahl des Fasermaterials bzw. Binders können diese Produkte in ihren technologischen Werten beeinflußt werden, z. B. hochsaugfähig, kurzdehnig, hohe Festigkeit, Porosität und Atmungsfähigkeit. Auf Grund solcher Möglichkeiten können solche Produkte verwendet werden für Fensterleder, Schlupfriemen, Futterleder, Futterstoffe, Filtern: edien, Teppichunterlage u. dgl.By choosing the fiber material or binder, these products can improve their technological values be influenced, e.g. B. highly absorbent, short stretched, high strength, porosity and breathability. Due to such possibilities, such products can be used for chamois leather, Slip straps, lining leather, lining materials, filters: media, carpet underlay, etc.

Werden sie anschließend mit einem Deckstrich versehen (Finish), können sie als Kunstleder bzw. Lederersatz verwendet weiden.If they are then provided with a top coat (finish), they can be used as artificial leather or Leather substitute used willow.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß Vliese aus beliebigem Abfall-Fasermaterial auf gleiche Weise verarbeitet werden können. Kurze Baumwoll-Abfallfasern können z. B. bei hohen Vliesgewichten nur genäht, nicht aber genadelt werden. Das erfindungsgemäße Verfahren ist somit den bekannten Verfahren überlegen, da es unabhängig von der Art des Ausgangsvlieses durchführbar ist. Durch das Nähen eines Vlieses aus minderwertigen Fasern mit einem hochreißfesten Synthese-Faden kann weiterhin ersteres eine Festigkeit in Laufrichtung des Fadens erhalten, die etwa der Festigkeit des verwendeten Fadens entspricht. M?n kann dabei beim nachträglichen Imprägnieren mit weniger Bindemittel auskommen.The advantages achieved by the invention are that nonwovens are made from any waste fiber material can be processed in the same way. Short cotton waste fibers can e.g. B. at high fleece weights can only be sewn, not needled. The inventive method is thus superior to the known method, since it can be carried out independently of the type of initial fleece is. By sewing a fleece made of inferior fibers with a highly tear-resistant one Synthetic thread can furthermore receive a strength in the running direction of the thread which is about corresponds to the strength of the thread used. M? N can do this with subsequent impregnation get by with less binder.
