Description
Für die Herstellung von Vliesstoffen kommt sowohl der sog. trockene als auch der nasse Weg infrage.Both the so-called dry and the wet method are possible for the production of nonwovens.
Beim trockenen Verfahren bereitet man mit Hilfe einer Krempel und eines Querlegers bzw. eines sog. Bandow-Webbers ein loses Faservlies, das darin anschließend mit Bindemittel imprägniert wird. Nach dem Aushärten des Bindemittels liegt dann der fertige Vliesstoff bereits vor. Entsprechende Verfahren zur Herstellung von Vliesstoffen auf trockenem Wege sind in der Literatur häufig beschrieben. Es sei hier nur auf das Buch "Nonwoven Fabrics", Published by Nonwovens Associates, P. 0. Box 323, Cambridge, Massachusetts, Copyright 1959 verwiesen. In the dry process, a loose material is prepared with the help of a card and a cross-layer or a so-called bandow webber Fiber fleece, which is then impregnated with binding agent. After the binding agent has hardened, the finished one is then in place Nonwoven already before. Corresponding processes for the production of nonwovens by dry means are in the literature often described. Let us just refer to the book "Nonwoven Fabrics", Published by Nonwovens Associates, Referenced P. 0. Box 323, Cambridge, Massachusetts, Copyright 1959.
In den letzten Jahren gewinnt die Herstellung von Vliesstoffen auf nassem Wege immer mehr Bedeutung. Hierbei werden Stapelfasern in einem sehr großen Überschuß von Wasser auf geschlämmt. Gleichzeitig enthält das Wasser ein Bindemittel, das vorzugsweise zur Koagulation gebracht wird, wobei sich das koagulierte Bindemittel fast ausschließlich auf den Oberflächen der imIn recent years, the manufacture of nonwovens by wet means has become more and more important. This is where staple fibers are used slurried on in a very large excess of water. At the same time, the water contains a binder, which is preferably is brought to coagulation, the coagulated binder almost exclusively on the surfaces of the im

Wasser aufgeschlämmten Fasern absetzt. Anschließend gießt man dieses Faser-Bindemittel-Gemisch auf einem in der Papierindustrie üblichen Steilsieb ab.Water suspended fibers settles. Then you pour this fiber-binder mixture on a steep sieve customary in the paper industry.
Auf dem Sieb verbleibt dann das nasse, bindemittelhaltxge Vlies, während das überschüssige Wasser abtropft. Man kann dieses nasse Vlies dann anschließend bei Temperaturen, bei denen das Bindemittel entweder vulkanisiert oder aushärtet, trocknen und erhält dann ebenfalls einen Vliesstoff.The wet, binder-containing fleece then remains on the sieve while the excess water drips off. You can get this wet Fleece then then at temperatures at which the binder either vulcanized or hardened, dried and then also given a non-woven fabric.
Für viele Zwecke werden aber sog. perforierte Vliesstoffe bevorzugt. For many purposes, however, so-called perforated nonwovens are preferred.
Die Erfindung betrifft nun eine Vorrichtung zum kontinuierlichen Perforieren von Vliesstoffen, unmittelbar nach ihrer Bildung auf dem Steilsieb. Im einzelnen geschieht das laut beigefügter Zeichnung folgendermaßen:The invention now relates to an apparatus for continuous Perforating nonwovens immediately after their formation on the steep sieve. This happens in detail according to the attached drawing as follows:
Das Steilsieb übernimmt die aufgeschlammte Vliesbahn gemäß Fig. I und entwässert mit Saugkästen gemäß Fig. II. Am Ende des Saugkastens läuft eine Musterschablone sich drehend mit (1). In diesem Schablonenkörper befindet sich ein Rohrkörper 2, feststehend, welcher durch eine Schlitzdüse 3 mit Druckwasser das entsprechende Muster in die Stoffbahn als Loch- oder Profilstruktur einschießt.The steep sieve takes over the sludged fleece web accordingly Fig. I and drained with suction boxes according to Fig. II. At the end of the suction box, a pattern template rotates with it (1). In this template body there is a tubular body 2, stationary, which through a slot nozzle 3 with pressurized water the corresponding patterns in the fabric as a perforated or profile structure shoots in.
Eine weitere Version ist die, daß man anstelle von klarem Druckwasser eine Faserflotte in einer Konzentration von 0,01 bis 0,1 % durch die Schlitzdüse schickt, Faserablagerungen eine erhöhte Profilierung auf der Stoffbahn belegen und man somit im umgekehrten Sinne eine erhabene Struktur erhält. Je nach Schablonenstärke s die vorwiegend bei 0,1 bis 2 mm liegt, können die erhöhten Stellen auf der Vliesbahn variiert werden oder aber je nach Druckusiterschieden des Wasserstrahls kann man die Lochstruktur bzw* die Profilierung der Stoffbahn auf dem-Steilsieb verändern. Another version is that instead of clear pressurized water, a fiber liquor in a concentration of 0.01 to 0.1% is sent through the slot nozzle, fiber deposits occupy an increased profile on the fabric web and thus, in the opposite sense, a raised structure is obtained. Depending on the stencil thickness s, which is mainly 0.1 to 2 mm, the raised areas on the fleece web can be varied or, depending on the pressure differences in the water jet, the hole structure or the profiling of the fabric web on the steep screen can be changed.

Bei Fasermischungen, die mit Bindefasern oder Bindemittel, auch in pulverisierter Form, versehen sind, kann man anstelle von kaltem Wasser mit heißem Wasser arbeiten und dadurch zugleich eine Bindung zwischen den übrigen Faseranteilen erreichen.In the case of fiber mixtures, which are provided with binding fibers or binding agents, also in powdered form, one can instead of cold water work with hot water and at the same time achieve a bond between the remaining fiber components.
